Surveying for Birds in Bangladesh
February 3, 2023
Students at Chandipur Model High School in Rangpur, Bangladesh conducted bird surveys under the direction of their teacher, Khalilur Rahman.
Students worked in groups to observe birds in three areas of their community. They divided the areas into three categories which are, 1) Residential areas, 2) Markets and schools, and 3) Open areas consisting of vegetation and water bodies. The students observed the areas, spotted birds, and identified the bird species. They also took photos and videos of the birds using their android mobile phones and showed them to their teacher to confirm. They recorded the number of birds of each species in their notebooks. Students compared the number of birds they had recorded from three areas. Next, they brainstormed the reasons for the differences in the number of birds they found in those areas. They search online to learn more about the birds they saw in their locality to verify their ideas.
Barn Owls in Israel LIVE!
January 20, 2023
Barn Owls are a fascinating species of bird. They are found nearly across the globe, often nesting near areas of human inhabitation, especially around agricultural lands and in the adjacent structures that are their namesake. These owls are important predators of rodents and other small animals.
In Even Yehuda, Israel, a webcam has been placed in a barn owl nesting box. The camera gives us a window into the secret lives of these beautiful birds. At this writing, the parent birds are caring for three chicks with two more eggs almost ready to hatch. The male bird has been an excellent provider. A visit to the webcam will likely show the rodent meals stored in the box to feed the hungry chicks. Most of the prey seen in the box are jirds, a species of rodent very similar to the gerbils that are often kept as pets.
Here is a link to the Charter Group of Wildlife (Israel) webcam
Work is being done to determine if the cosmopolitan barn owls are actually distinct forms. Groups such as the Global Owl Project are collecting data to determine if the barn owls in the Americas are a separate species.

Venomous Snakes of Southern Africa!
September 22, 2022
Our friend Rob C. took part in an expedition to South Africa and Namibia to find and photograph a variety of reptiles and amphibians. His team encountered many different specimens including several venomous snakes. These animals are fascinating examples of creatures that are adapted to the varied habitats of that region.
Check out the specialized adaptations on the Peringuey’s Adder, a desert dweller of Namibia.
Rob traveled with a group of fellow “herpers” or reptile and amphibian enthusiasts. They explored a variety of different habitats to observe the unique species found in Southern Africa.
Here’s where the team traveled to look for the snakes and other animals.
The habitats of South Africa are quite varied. Temperatures and rainfall amounts are impacted by the features of the landscape along with elevation.
And now for the snakes! While many people are fearful of snakes, they are beautifully adapted to their environment. Venomous snakes in particular are interesting in their ability to capture their prey items by delivering venom through hollow fangs. While many of the snakes pictured can be dangerous to humans, the animals would prefer to avoid contact with people and simply be left alone.
One of the snakes responsible for many bites throughout Africa is the Puff Adder. This snake has excellent camouflage which it uses to ambush its prey. Unfortunately, this characteristic frequently results in the snake being stepped upon by people. The bite of the Puff Adder can be deadly, though if treated quickly with antivenom, people can survive.
One of the most feared snakes in South Africa is the Black Mamba. These snakes are excellent climbers and will frequently be found near human settlements. These are the second longest venomous snake, reaching lengths over 3 meters and exceeded only by the King Cobra.
The Bibron’s Stilleto Snake is an unusual creature. The snake digs beneath the ground in search of burrowing reptiles such as lizards and other snakes. This snake can deliver a painful bite even when held behind the head, using its fangs to slash its victim.
High up in the mountains where temperatures are cooler is the home for the Berg’s Adder. This little viper is unusual in that its venom primarily affects the nervous system of its prey. The Berg’s Adder feed largely on lizards and amphibians, but will also consume small mammals.
Some of the group traveled from South Africa to Namibia, a much drier environment with some different snakes to observe.
One of the snakes with a very specialized adaptation is the Black Spitting Cobra. These snakes have developed the ability to “spit” their venom as far as 2 meters. If the venom hits the eyes, it can cause permanent or temporary blindness. This is used primarily as a defensive mechanism. This snake was actually found climbing in a nest of weaver birds. These birds construct hanging basket-like nests that can be quite large.
The Desert Mountain Adder is a snake of rocky slopes and hillsides. It’s bite, though painful, is not likely to be deadly to humans. This snake feed mainly upon lizards and rodents.
The Anchieta’s Cobra is a “generalist” in terms of its diet, feeding on frogs and toads, rodents, and birds including poultry.
The Shield-nose Cobra is not truly a cobra but has a small hood that it extends when threatened, hence its name. The large scale on its nose helps the snake burrow into the dry sand in search of the lizards and rodents that make up its prey. The bite of this snake rarely causes death in humans.
A challenge for life in the desert is the blowing sand that these animals encounter on a daily basis . An adaptation that many snakes develop are “horns” that protect the eyes from sand. In fact, the sidewinder rattlesnakes of the desert southwestern United States have a similar adaptation. This Many-horned Adder’s prominent horns help it to survive in the harsh desert environment.
The little Horned Adder has excellent camouflage to help it blend in with the desert and dry savannah that make up its habitat.
Thanks Rob for sharing your experience with us!
May 13, 2022
Students at Mill Creek Middle School took part in a BioBlitz. This is an activity in which students conduct surveys of the variety of living things found on the schoolyard. Ms. Gallihugh’s eighth graders created informative (and sometimes funny) summaries of their experience! Here’s a video from Tyler:
January 6, 2022
Eighth grade students from Mill Creek Middle School in Calvert County, Maryland participated in a stream survey to assess the health of local streams with the health of the CHESPAX environmental education program. Students contributed some blog posts to share the story of their experience.
During the CHESPAX visit to Mill Creek the students found many diverse types of bugs that are commonly found in various levels of polluted water. They bought bags of leaves that were placed in a stream that led out to St. Leonard’s creek. They brought in these leaves so that we students could see what benthic macroinvertebrates were living in this stream. By looking at the macroinvertebrates in the stream we could tell the quality of the stream’s water and the level of pollution.
This is a hellgrammite; I find these organisms remarkably interesting due to their claw like pinchers and their false legs that act as gills. These little bugs are found in water that may have some pollution and they tend to be semi- tolerant. The bugs can be very in size and are like lions of the streams. They can be called this due to their big pinchers and their ability to hunt other bugs and invertebrates.
These benthic Macroinvertebrates are called scuds, these can live in semi polluted water but just because they are semi tolerant of polluted water doesn’t mean that’s all they can live in. The scuds were the most common organism that was found throughout all these buckets of leaves. These organisms can be found along with ones that aren’t tolerant of any pollution. If the water quality gets too low and one food source is lacking these organisms can food off of algae, which thrives in water which can be lower quality.
This is a rat-tailed maggot, rat tailed maggots can be found in very polluted water with little cleanliness. This organism lives alongside the two other semi tolerant species. This species is fascinating due to their ability to survive in water that is heavily polluted. They can even live in puddles found in parking lots which may have oil, trash, and other pollutants in them.
We did an experiment to see how clean our streams are by using bugs. We use mesh bags and put leaves in them. You then tie it closed and put it in your stream for a few days. When you get after a few days you open the mesh bag and dump the leaves in a bucket with some water in it about half way full. Get a separate container and grab a hand full of wet leaves with some clean water in it and look for bugs. Depending on the type of bugs you find Is how clean your stream is. But the stream must be at least 1 ft deep.
Autumn described the project:
This is the type of bag you must use for this to work. You use this type of bag because the holes are big enough for the bugs can crawl in and make a borough to live in.
This is a midge fly larva also known as a blood worm. This worm is tolerant of pollution. If you find these there is a high chance that your stream is not clean. It feeds on algae and bacteria. When it becomes an adult, it becomes irritating, these tiny flies may bite.
If you see this. This is a caddisfly larva it is very sensitive to pollution if you see these this means that there is a higher chance that your stream is clean. They eat algae.
The adult version of the caddisfly is medium with hairy wings. This is the adult caddis fly.
When CHESPAX visited Mill Creek Middle School so we could test the stream at Flag Ponds.
One of the most fascinating insects was the Hellgrammite. The Hellgrammite is a Dobson fly larva. The Hellgrammite is tolerant of water that has little pollution. The Hellgrammite has spikes that look like legs, but they are not. Hellgrammites have large pinchers; Hellgrammites can grow up to 2 inches before becoming a dobsonfly. Hellgrammites are like the tigers of the ecosystem. This is a picture of a Hellgrammite.
Pollution and things such as growing development in Prince Frederick can easily ruin the creeks and streams around the area. When rain falls and causes erosion, the sediment run-off into streams can make it difficult for the more sensitive animals to live and thrive.
The pollution dirties the water and therefore makes it harder for organisms to live. When the pollution fills the water, the grasses at the bottom of the stream don’t get enough sunlight. Though some organisms like the damselfly can live in moderately polluted water, other organisms may not be able to.
For the past few weeks, we have been learning about biodiversity. On November 16th we searched through leaf piles that have been sitting in a stream to determine the water quality of the stream. We did this by searching through the leaves to find what Benthic Macroinvertebrates were living in the leaves. The macroinvertebrates helped us determine the water quality because some of them will only live in a stream with a certain water quality.
In order to search through the leaves, we poured a bit of water in the bottom of a tub. We put a handful of leaves in the bottom and used droppers and spoons to get out any bugs we found.
When we got any of the bugs we put them in an ice cube tray filled with water so that we could see them and be able to look closely at them. This also made sure they didn’t get hurt by keeping them in water.
After getting all of them out we put some of the bugs into bigger cups under a camera so we could zoom in and get a closer look at them. We carefully put them into the cup as to not harm them.
Leaves are important because they provide shade and shelter for the bugs and the fish in the water. Warm water can kill, so the shade is important in many ways that the animals need to survive, They also provide food for some bugs and fish.
When CHESPAX visited Mill Creek Middle School my class learned about all the different types of bugs and how well they can survive in the ponds. There are some bugs that are sensitive, less sensitive, and lastly tolerant of the stream’s healthiness in the water. In this experiment we were given buckets filled with leaves and on those leaves would living organisms.
This is a riffle beetle, this organism is very interesting for a few reasons. For example, one of our tables found this and we saw that the beetle will get relatively long legs and tarsal claws when it gets older. The riffle beetle helps clean the streams by feeding on organic decay found in the water such as decaying leaves, rotting plants and microscopic algae. These insects are moderately intolerant to the pollution in the streams and rivers. So, it’s very good to find these in your rivers because then you know it’s a bit clean.
Two days ago, CHESPAX came to our class to teach us about biodiversity in Calvert. They gave us leaves they had put in bags and set in a stream in Flag Ponds for about 2 weeks to look for bugs in. At first It didn’t sound pleasant. But it turned out to not be horrible. We set the leaves into a bucket of water and started searching. My group didn’t find the most bugs or the biggest ones, but we found a few. When we were looking at the ones we found, we learned they each have sort of a “job” that they do to contribute to their mini ecosystem. Which is great because if everything did the same thing then the ecosystem would eventually stop working causing everything to die.
We have been learning about biodiversity for the past few weeks. There will be a leaf packet left in a stream for 2 weeks or more. The leaf bag will collect bugs, then you end up surveying it to determine the health of the stream from the diverse kinds of bugs and how tolerant they are to pollution and their diversity.
This bug is a riffle beetle. This bug is sensitive to pollution, so if the water quality was bad, we would not have found it in our leaves. It’s a good sign the waters healthy.
This is a scud; they swim on their side. It is a bottom feeder that eats dead stuff. According to Mr. Harten, scuds are like the vultures of the stream. Scuds are less sensitive to pollution. This is an OK sign for the water. I like scuds. They look like they’re dancing. I love the scud my table called Shrimpy.
The leaves were soggy and wet, but they created a fantastic habitat for mysterious insects. When CHESPAX came to our classroom with these leaves and told us we were going to find bugs, we were a bit skeptical. However, after searching through this stream habitat in our classroom, we discovered that the creek at Flag Ponds Nature Park had a good water quality rating based on the bugs we found. Certain insects do not tolerate pollution so finding them is a sign of good water quality. We also wanted to find a variety of bugs because the higher the biodiversity, the healthier and more resilient the ecosystem. It was surprising, it was good.
This is a casemaker caddisfly; they make a home out of leaves. They spew a web that sticks them together. This species is sensitive to pollution and hard to find because their house blends in with the leaves so well. That’s an incredibly good sign and find.
Leaves are not just important to the trees they grow on. Leaves provide shade for streams that keep the stream from getting too warm and make it a great habitat for species within the warm weather. In the cold weather, the leaves fall from the trees and into the streams, providing habitats, homes, and food for BMI’s (benthic macroinvertebrates AKA simply bugs). We collected some leaves and searched for some bugs to help us figure out if a stream was healthy. It was.
Biodiversity is important for ecosystems to be healthy. On November 15, 2021, CHESPAX came to Mill Creek Middle School to help us complete a stream survey for a stream by Flag Ponds Nature Park. A few weeks ago, we made leaf packs for them to put into it, which they left there for ten days after which they were taken out. In the days leading up to when we did the survey, we talked about how biodiversity in ecosystems helps them be more resilient by keeping the gene pool large enough that it can be able to adapt to changes in their environment. During the survey, we found a variety of creatures.
Overall, our stream did okay in its water quality test, but it did not have a lot of biodiversity. We had mayflies in the sensitive category, Damselflies and Scuds in the less sensitive category, and aquatic worms in the tolerant category. Thank you for reading!
Biodiversity is when an ecosystem has different variants, that makes it stronger. A couple of weeks ago we sent bags with leaves to some friends at CHESPAX. They took it and put it into a stream. Bugs then caught on to those leaves and we took them back to class for studying. We found different types of bugs, and that told us how diverse the stream was, or how much biodiversity was in the stream.
This picture shows us looking for bugs in the water. When we found one, we would scoop it up, and put it into the ice cube tray. From there, we could see it clearer and try and figure out what it is.
This is a damselfly. It is in the less sensitive to pollution section . Since we know that we have a decently sensitive bug in the river. We could say that our river couldn’t be too polluted. We do not know how much pollution, but it could not be that bad.
Goodbye to the Maryland Darter
November 11, 2021
The biodiversity of our world can be awe inspiring as the contributions to this blog have demonstrated. We have learned about ducks and bulbuls in Bangladesh, birdlife in Poland, and dolphins along the New Jersey shoreline. This biodiversity is a part of our natural heritage and for many, as a source of pride to share their local flora and fauna.
Sadly, the loss of biodiversity is a very real global issue. This hit home in the state of Maryland this week when the Maryland Darter, a small fish native to a single creek along the Susquehanna River, was officially declared extinct by the state’s Department of Natural Resources. This fish was last sighted in 1988, but has not been relocated despite numerous surveys by scientists across the region. This species of darter was the only animal that had its entire range limited to the state of Maryland.
It is important to remember that our global biodiversity is not guaranteed. Let’s celebrate, but also protect, the plants and animals that help to sustain all life, including our own! To read more about the Maryland Darter, here’s a link to an article from Chesapeake Bay magazine.
Dolphins on the Jersey Shore
October 19, 2021
Our friend and retired educator, Robin Shaffer, shared these amazing images of Bottlenose Dolphins that he observed from his kayak near Ocean City, New Jersey (U.S.A.). Dolphins are naturally curious and provided Robin with some excellent views as they played and hunted for fish just offshore.
These coastal Bottlenose Dolphins are migratory. They will soon leave the New Jersey shore for the warmer waters of the Carolinas, returning in May of next year. It is possible that a few animals will remain through the winter if temperatures are mild and if fish are plentiful.
Students are Buzzing about these Mystery Creatures!
October 13, 2021
An important skill for young scientists to develop is the ability to record interpretations from direct observations of natural phenomenon. Seventh grade students in Calvert County, Maryland began the school year with an investigation of “Mystery Creatures”, live aquatic organisms that seemed to undergo change with each passing day. Students recorded their observations and learned to create scientific drawings to document their findings. These skills will be applied throughout the year as they encounter new scientific concepts and phenomena.
Thanks to Mr. Kelsey from Northern Middle School for sharing some examples of excellent scientific drawings from his students!
Students made predictions about these mystery creatures. Some thought the animals might be Sea Monkeys (which are really brine shrimp). Others knew that these organisms were in reality, mosquito larvae. Mosquitoes begin their lives as aquatic creatures, spending time as larvae and pupae before emerging from the water as adults. Classes received sets of mosquito chambers or pupators containing larvae. These chambers allow the larvae to develop through their aquatic life cycle and emerge as adults in an enclosed chamber.
There are lessons to be learned from this experience beyond basic scientific process skills. Throughout the year, students circle back to this early experience with mosquitoes. For example, students learn that an effective way to combat mosquito populations is to break their life cycle by removing water sources on their property. Students also raise native Gambusia or “mosquito fish” as a biological control for the larvae. These methods are a desirable alternative to chemical pesticides which can have impacts on other insects and wildlife.
What Does Biodiversity Sound Like?
August 26, 2021
“All of nature begins to whisper its secrets to us through its sounds. Sounds that were previously incomprehensible to our soul now become the meaningful language of nature.” Rudolph Steiner (1861-1925)
The soundscape of natural areas has been the inspiration of authors and poets for generations. The chorus of songbirds on a spring morning, the nighttime buzz of insects, the croaking of frogs from a nearby pond are the voices of nature that can provide calming relief from the stresses of modern world.
The sounds of nature also reflect the biodiversity of the environment. Eighth grade students in the Calvert County Public Schools (Maryland, USA) are investigating the importance of biodiversity as a measure of environmental health. A grant from the Calvert Environmental Trust for Youth will help these students use the sounds of nature as a measure of biodiversity and to create a digital library of nature sounds. Students will use SongMeter Micro recorders produced by Wildlife Acoustics. The tiny recorders are about the size of a deck of cards and will automatically log nature sounds day and night when deployed on our schoolyards. This data will be shared with the Maryland Biodiversity Project, a group seeking to document the diversity of life across the state.
Toward the end of the last school year, the recorders purchased through the grant were field tested with students at Mill Creek Middle School. The images and sounds below are examples of how the project will be implemented.
Along with the collection of useful scientific data, it is hoped that the participating students begin to hear the “whispered secrets” of the language of nature.
Afsara Discovers some Duck Eggs
August 23, 2021
Hi. My name is Afsara Ibnat. I am 14 years old. I read in grade 8 in BAF Shaheen College Dhaka, Bangladesh.
In March 2020, when lockdown started in Bangladesh due to outbreak of Corona pandemic, I along with my mother and elder sister went to Moulvibazar, a north-eastern district of the country, to stay with my father. My father was the Officer Commanding of Moulvibazar Radar Unit, an Air Force station, during that time.
While living there, one day I and my sister were taking a walk and we came across some small eggs around a pond. We took pictures of them and showed to our father. He said that those were the eggs of “Bali Hash” (Lesser Whistling Duck). A flock of these ducks used to roam around this pond quite often so they laid their eggs there.
The Lesser Whistling Duck, also known as Indian Whistling Duck or Lesser Whistling Teal, is a species of Whistling duck that breeds in the Indian subcontinent and Southeast Asia. It’s scientific name is Dendrocygna javanica. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call.
June 8, 2021
Hello. My name is Zaheen P. I am 9 years old, and I read in grade 2 in BAF Shaheen English Medium College.
Last Friday, I went to my grandparents’ house at Cumilla, Bangladesh.
On Saturday morning, I went for a walk with my parents and saw these little colorful birds on a tree. With the help of my father, I captured the photo. This bird is called ‘Bulbuli,’ scientific name- Pycnonotus cafer. It is very common in Bangladesh. It is a short-neck bird with a high voice. It is a magnificent bird.
The Great Eastern Brood
May 28, 2021
There something magical happening across parts of the eastern United States this spring. Billions of Periodical Cicadas are emerging from their underground tunnels and burrows where they have lived for the past 17 years. The Latin name Magicicada, evokes the mysterious nature of these fascinating insects.
Periodical Cicadas are a North American phenomenon with 15 different broods that emerge on 17-year and 13-year cycles. Most of the populations occur from eastern seaboard states to the mid-west. The current brood that is emerging in the states of New York, New Jersey, Pennsylvania, Delaware, Maryland, District of Columbia, Virginia, West Virginia, North Carolina, Georgia, Tennessee, Kentucky, Ohio, Indiana, Illinois, and Michigan is known as Brood X or the Great Eastern Brood. These insects last appeared in 2004.
As the insects begin to emerge after their 17 year subterranean journey, they tunnel upward and crawl onto the nearest tree or any vertical structure. Here they shed their skin and take flight.
Insect predators such as birds and reptiles will gorge themselves on this sudden abundance of protein that emerges from beneath the ground. While copperheads will eat cicadas readily, the emergence doesn’t cause an increase in their population or activity levels.
Male cicadas congregate in trees and emit a loud buzzing sound that seems other worldly. The insects themselves are quite unusual in appearance, with bright red eyes and orange-veined wings. The noise can be deafening when there are thousands and thousands of these insects in a single tree. In some areas, there can be up to 1.5 million cicadas in an acre of land! That’s a lot of bugs!
The cicada chorus of the Great Eastern Brood will soon fall quiet. We can look forward to their return in the spring of 2038!
Goodbye until 2038!
HAWKS OUTSIDE OUR WINDOW
April 8, 2021
Mrs. Wiles from Plum Point Middle School in Calvert County, Maryland (USA) shared this great video of a pair of Red-shouldered Hawks nesting right outside of her classroom window. It’s interesting to listen to the counterplay of the classroom discussion and the screeching of the two hawks from a nearby tree. It’s a reminder that while we all go about our own business, incredible natural events are happening just outside of our window! Thank you Mrs. Wiles for sharing the view from your window!
Our friend and blog contributor Irum’s school in Pakistan is still in quarantine and unable to contribute to the Global Biodiversity Blog. Irum was kind enough to share a post from her brother, Dr. Ali, a Senior Scientist currently living with his family in Warsaw, Poland. Thanks to Irum and Dr. Ali for this interesting post!
Biodiversity in Poland
March 22, 2021
In a time of quarantine when you need someone to spend time with, Polish birds and animals will not disappoint you. You will be hooked by their friendly nature. What makes them so friendly? No specific reason except having friendly people and a friendly environment around them. The people in Poland always bring something to feed them with. That is why the birds are never scared of coming close to them.
No matter what language you speak, the birds in Poland understand all kinds of languages when you get them to eat out of your hand. You simply place nuts or seeds in the palm of your hand and they will not let you wait for long.
Polish swans (Mute Swans)- large sized waterfowl that add beauty to ponds, marshes and lakes. They are also friendly and you can feed them fresh bread or grains.
Warsaw is the capital city of Poland. The most unusual thing here is the friendly nature of squirrels, birds and peacocks. After coming here, you feel a bit closer to nature. You can spend hours relaxing, lying on the grass, and feeding the birds and the squirrels.
Blue peacocks are among such big birds who sometimes get noisy but quite friendly in nature when you are ready to feed them. They trust your presence and sense the smell of food in your palms. Even if you are a foreigner, these Polish birds and little animals make you feel at home.
When birds bloom: A post lockdown birding in the Western Ghats
February 2, 2021
Bird photographers would always cherish to see birds perched at eye level on the branch of a tree with a shallow depth of field. It gives the photograph a nice bokeh effect. I went to the resort of my friend, holding close the dreams I had the previous night. In the dream, I saw myself looking thorough the view finder of the camera with a big telephoto lens attached. I was trying to hold my breath so that I could prevent the camera from shaking. I did not remember the photo I took with that imaginary telephoto lens though! When I try to remember any dream later, I normally do not have a very clear idea about it. Most often what remains is a mosaic of visuals and it’s pretty hard to string them together to make some sense out of them.
The resort is situated in the buffer zone of the Western Ghats in the Wayanad district of Kerala State. It has coffee plantations all around the property. The hilly slopes with occasional tall trees and a brook that flows along the plot, make it a haven of birds! Plenty of them. I actually woke to the heavenly note of Malabar whistling thrush….(link to full text of article)

A recent review of photos from the CHESPAX Submerged Aquatic Vegetation monitoring program, yielded this as of yet, unidentified creature. A quick thinking Ms. Holly Fallica from Calvert Middle School captured a fleeting image of this beast on the Patuxent River during a Fall 2019 CHESPAX field trip.
A review of literature lead some to speculate that this could be an out of range sighting of Chessie, a legendary sea monster that may inhabit the middle of the Chesapeake Bay. Other observers have indicated that it’s probably just a slime covered log.
Mr. Harten from the CHESPAX staff, perhaps made a fateful decision to reconnect with the creature on Friday, March 13, and has not be seen around the office since that date.
Happy April 1!
Elephants of Kerala
January 28, 2020
VoiceThread is an interesting communication tool to link schools from different regions for discussions about a range of topics and interests. Some teachers from Calvert County Schools in Maryland (US) have joined with teacher Sujith S. from Pantheerankave Higher Secondary School in Kozhikode, Kerala (India) on a project to allow students to communicate on global biodiversity. One of Sujith’s students, Ashiqa, put together an excellent presentation about the role of the elephant in Kerala’s culture and some of the problems for elephants in a captive situation.

Exploring Xochimilco through EarthWatch
January 17, 2019
Ms. Fallica from Calvert Middle School was a participant this summer in an EarthWatch expedition to central Mexico. During this experience, she had the opportunity to engage as part of a team of educators and interact with local scientists. Below is Ms. Fallica’s account of her experience.
We worked with the REDES team throughout the week. REDES (Restauración Ecológica y Desarrollo A.C.) is a local non-profit that aims to increase ecosystem health of wetlands in Xochimilco, Mexico by monitoring water quality and local biodiversity, providing research results to policy-makers, and educating local farmers on sustainable agriculture and business strategies.
They taught myself and 6 other teachers about their efforts and outreach in improving the health of Lake Xochimilco, as well as the ancient farming technique of “Chinampas”. The practice of Chinampas is a type of agriculture which used small, rectangular areas of fertile land to grow crops on the shallow lake beds. There are still some intact Chinampas being used with the same ancient gardening techniques as the Ancient Mayans who once lived in Mexico City.
We learned throughout the week how imperative it is to not only keep these agricultural traditions alive, but to keep the canals and water clean for the Axolotl. The Axolotl is a Salamander- like amphibian that can regenerate many of it’s own organs and body parts. It is now critically endangered and feared to be almost extinct in the wild. Native species like these amazing creatures and the massive amount of migratory bird species that visit Mexico City is another reason why the health of Xochimilco is so important.
We went on a trajinera (colorful boat) with REDES through the canals of Xochimilco that day to count the various bird species and have lunch in the Chinampas. I think we saw over 17 different kids of birds just within a few hours! It wasn’t even migration season yet.
I learned so much working with the team of scientists from REDES and the public university of Mexico City and made so many connections between their efforts in conservation and what we have been working on here in Maryland. The water quality testing and biodiversity studies that we do together with CHESPAX is very similar to what this Earthwatch expedition was all about in Mexico.
I felt like I was the only teacher who attended this expedition who could make similar connections between the science field work and the classroom because of all the research that we do here in Maryland with the Chesapeake Bay Watershed.
The pictures above show us collecting water samples from the canals, as well as Macroinvertebrate samples. Based on the macroinvertebrate diversity and sensitivity to pollution, we were able to gain an understanding of the canals’ health. It was a tedious job, but the data that we were able to collect really helped us gain a better understanding of the health of this ecosystem and factors that could be impacting the native species, like the critically endangered Axolotl only found in Mexico city. This science work is helping Mexico to better understand the past, present, and future ecological impacts of this ancient land.
For more information, please refer to our Earthwatch Expedition Blog. Each of us worked on the blog to keep track of what we did and learned each day while in Mexico. The link is below:
Mill Creek Middle School Investigates Stream Health
January 6, 2020
Students from Mrs. Gallihugh’s 8th grade science classes at Mill Creek Middle School reflected on their recent stream survey experience with the CHESPAX staff.
The stream score we received indicated pollution, but the species present tell a different story. In science class, we examined bags of leaves from Battle Creek and Flag Ponds. We used bags of leaves because they collect Benthic Macroinvertebrates (BMIs) when left in the water. We found many different species from both streams. We did this because the varieties of BMIs can indicate the health of a stream because they vary species that are sensitive, such as Caddisflies and Stoneflies, to species that are tolerant to pollution, such as Leeches and Lunged Snails. We found that while there were some sensitive species in both areas, such as Mayflies and Caddisflies, we scored fair. This strange because Mayflies and Caddisflies cannot survive in the presence of pollution, but we only scored fair. It indicates that there’s another issue separate to pollution present.
Our class sampled Benthic Macro-Invertebrates (BMI) in two local streams. Since the streams are close geographically, we expected them to be similar with water quality and the insects we find. Some similar insects we found were mayflies, netspinner caddisflies, scud and aquatic worms. The crane flies, net spinner caddisflies and scud in Battle Creek show the medium tolerance rate. In Flag Ponds we found sow bugs, crayfish and damselflies. These BMI also show a less sensitive tolerance rate. These insects both contribute to the fair biotic index of 5.67 for Flag Ponds and 5.51 for Battle Creek.
There are also many differences that can be found between the 2 streams, things like different (Percent EPT is short for the total number of Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies)). EPT and individuals per bag. The EPT at flag ponds %13.5, The EPT at Battle Creek is %16.3. The individuals per bag in flag ponds is 14.9 while in battle creek its 22, with this information we can determine that battle creek is a healthier stream than flag ponds. Battle Creek has more bugs than Flag Ponds with a total number of species coming in at 15 species, Flag Ponds only has 11 species in total. All things considered Battle Creek is a healthier stream, it has more species, higher EPT, and the individuals per bag is greater. Flag Ponds has lower EPT, lower individuals per bag, and less species. If you want a place to test to find a variety of species, go to Battle Creek.
Our class surveyed two different streams for Benthic macroinvertebrates. Since the two streams were so close, we predicted to find similar data from each of the streams. And this was exactly what we ended up finding. We surveyed Battle Creek and Flag ponds. We found a lot of scuds in both ponds. Scuds indicate somewhat good water quality because scuds breathe by absorbing dissolved oxygen through their gills, they can’t live in severely polluted or stagnant waters that contain no oxygen.
Scientists use stream surveys to investigate whether ecosystem streams are healthy or not. In science class we surveyed two different streams in our county to see if they are healthy or not. CHESPAX had placed bags full of leaves in the streams. When the leaves are in the streams they collect the benthic macroinvertebrates (BMI). The leaves provide food and shelter for them. BMI’s are also collected within the leaves. CHESPAX had taken them out of the water and brought them to MCMS so us students can investigate them. We collected the BMI’s from the leaves to investigate whether the local streams were healthy or not. Some of the species like stoneflies and mayflies tolerate very little pollution. Species like crayfish and scuds tolerate some pollution. And leeches and lunged snails tolerate lots of pollution. Investigating the leaves helped us tell whether the streams are healthy or not.
The two separate streams we sampled were streams in Calvert County. We sampled Battle Creek and St. Leonard Creek at Flag Ponds. We tested each of them to see what the differences of each of them are. The health of the ecosystem around the stream can indicate that the stream is healthy. We collected benthic macro invertebrates and we found that each stream a biotic index grade level of fair. Both streams had a similar EPT% with Battle Creek having a 16.3% EPT and Flag Ponds having a 13.5% EPT. Both streams had similar BMI’s also they both had mayflies, netspinners, scud, midges, caddisflies, and aquatic worms. A couple unique to the Battle creek stream were gilled snails, lunged snails, stoneflies, planarians, leeches, craneflies, beetles, and helgramites. Some unique to the Flag pond stream were sowbugs, crayfish, riffle beetles, and damseflies. Overall both of these streams would probably look the same because of how many things they had that were similar like there Biotic Index and there EPT%
Lily focuses on the Gilled Snails that she observed and provides some excellent background information!:
Gilled snails were found in Mill Creek Middle School’s (MCMS) eighth-grade class stream surveys. Gilled snails tolerates little to no pollution in the creeks. Having the snails in the creek means that the stream is healthy. If a stream has lots of pollution it is not healthy, and all of the animals could possibly die. Gilled snails are a good indicator of a healthy stream because they can’t tolerate a lot of pollution. Having a lot of gilled snails in a stream is a good sign, the snails eat decaying plants or algae growing on rocks. This helps the stream because if there is too much algae the stream could become unhealthy and polluted, the snails eating the decaying leaves help also, if the leaves do not decay then the stream will become unhealthy because the leaves will pile up and leave no room for animals to hide and no place for the fish to swim around.
Gilled snails fall under the category of operculate snails. They can grow to be about 70mm as adults. Gilled snails have a fleshy body with no jointed legs or hard mouthparts. The parts of their bodies are the head, visceral mass, mantle, and foot. The visceral mass is what holds the snail’s organs, the mantel is a thin layer of soft tissue on the outside of the body and the foot is for movement. They use this t to move by gliding on a thin film of mucus secreted from the underside of the foot. The snails have a singular shell. The opening is on the right of the shell, this is what differentiates it from lunged snails. The shell opening has an operculum, which is a door that closes over the opening to protect the snail. Gilled snails have a set of eyes and two tentacles on their heads. Inside the mouth, there are lots of tiny teeth which are used by dragging them along food to eat, this is called the radula.
A snail’s diets consist mainly of algae, decaying underwater plants and occasionally, a snail will consume a very small aquatic animal, although it’s uncommon.
These snails are very flexible and can be found in most freshwater habitat due to how easily they adapt, although they are sensitive to pollution. They are less common in fast or turbulent waters and live for about one year. The snails let water enter their shells and use their gills to obtain dissolved oxygen from the water.
Eighth grade students of Mill Creek Middle School took survey of two streams, Battle Creek, and Flag Ponds. The data we acquired from this helped us determine the health of the two ecosystems. Finding the health of an ecosystem is important, so we can ensure that the stream can continue to survive. We first surveyed Flag Ponds and concluded that the biotic index was 5.67. We then found the biotic index of Battle Creek, which was 5.51. The biotic index indicates the health of an environment by indicating the types of organisms found in it. Both of the streams are fairly healthy, though they could be healthier.
Water Hyacinth (Eichhornia crassipes solms) in Vietnam
December 3, 2019
This is an article and video shared from Students Huy at 11A4 class of Mrs Linh Truong at Binh Thuy High School in Vietnam about Eichhornia crassipes solms when it is sunset.
The western part of Vietnam is associated with water. Here, plant life is very diverse and is the favored environment for Eichhoriaceae crassipes solms or Water Hyacinth of the Pontederiaceae species.
,They appear idyllic in association with the countryside in Vietnam, with light purple flowers growing in clusters at the top of the plant in the summer. The base of the hyacinth is ribbed in the shape of a bow and sprouts into an asterisk shape. The petiole bulges into a buoy-shape, resembling a jar. Stems and roots form large mats to help the plants float on the water.
Leaves grow fast so it is easy to clog lakes and canals. Often, Eichhoriaceae crassipes solms is used as organic fertilizer. Additionally, flowers are used as animal food, composting mushrooms, and for fertilizing.
Eichhoriaceae crassipes solms is very helpful for the environment, but the whole plant is poisonous.
Birds of The Himalayan Foothills
October 8, 2019
The diversity of birdlife across India is truly astonishing. Sattal is one of the famous locations to see an incredible array of birdlife in the lower region of the Himalayan mountains. Our friend Sujith S., traveled to Sattal after a Fulbright educator conference in Delhi. He was kind enough to share some of his photos which provide us a glimpse of the diversity of birds found in Sattal.
Squirrels in Russia
September 5, 2019
A few months ago, we requested that schools share their squirrels with the Biodiversity Blog. Squirrels are often fairly common, easy to observe species, yet they display an amazing diversity in their form and behaviors. We appreciate the recent post from the students at the Roshchinski State School in the Lipetsk region of Russia. Their teacher, Ms. Irina Azarova, shared their article on the squirrel species found near their school and across much of Russia. We appreciate this article very much and look forward to learning more about the biodiversity across our globe!
The Eurasian Red Squirrel is the largest subspecies of the common squirrel with very thick fur. Winter fur is very light, silver-gray with grayish ripples; the tail is pale gray with an admixture of blackish and yellowish-rusty tones. Red Squirrels are smart, beautiful and friendly. These animals belonging to the rodent family and they are very mobile and graceful.
They only have two broods a year, but in each litter, there are from 3 to 10 squirrels. The first brood is usually in March, the second is in the middle of summer.
Despite the good ability to reproduce, the number of Red Squirrels is small. In addition to the Crimean peninsula, these squirrels live on the territory of western Siberia and Kamchatka; they have recently been acclimatized in the Caucasus.
At home, Red Squirrels live in dry pine forests along the upper reaches of the Ob, Irtysh, Middle Yenisei and their tributaries. First, they were released for acclimatization in the forests of the Crimean region, as well as to improve the quality of local ordinary squirrel fur in the forests of the Kremen district of the Voroshilovgrad region and the Korosten district of the Zhytomyr region. But Red Squirrels found the most favorable climatic and natural conditions for life only in the Crimea. Here the location of the Red Squirrel is associated with a high yield of the main food of these animals – nuts; that is why squirrels live in forest plantations with dense thickets of hazel.
In spring and summer, Red Squirrels live mainly in the valleys of mountain rivers.
Late in autumn and winter, when snow falls in the mountains, they migrate to the watersheds in pine and beech forests or closer to orchards and vineyards. The nests in which they live and give birth to babies, are arranged in most types deciduous and coniferous trees. The first offspring they have is very early – at the end of April. After about 40 days of pregnancy, the female gives birth to three to five babies. The rates of its reproduction in the Crimean forests vividly testify to the successful acclimatization of Red Squirrels.
In our small-town zoo, there is a Eurasian Red Squirrel. It has been living there for already 5 years. A lot of children come to the zoo to see this beautiful animal. Our students work as volunteers to take care of the squirrel and other animals.
Backyard Birds in Punjab Province
August 14, 2019
Our friend and teacher, Irum Butt, visited her sister who lives near the desert regions in Rahim Yar Khan in Punjab province of Pakistan. Her sister’s family provides food and water for local wildlife and enjoy interacting with these visitors. See some of the photos and videos that she captured during the visit. Thanks Irum for sharing your observations!
This first video shows a pair of Black-rumped Flameback Woodpeckers as they drink from the water source in this backyard habitat.
This second video demonstrates the vocalizations of the Asian Koel, a member of the Cuckoo family. These birds are widely distributed across southeast Asia. Like most cuckoos, the Koel lays its eggs in the nests of other birds. The young koel are raised by these “foster parents”. This type of behavior is known as brood parasitism.
Red Squirrels and Global Education!
July 22, 2019
Back in February, we had put out a request for posts about squirrels. These animals can be found over much of the planet, varying to a degree from region to region around the world. Some nice images of some Red Squirrels were sent in by frequent contributor, Lizoon Nahar. Lizoon is a teacher at the BAF Shaheen English Medium School in Dhaka, Bangladesh.
Red squirrels range over much of the northern tier of the United States and into Canada. Their populations dip southward along the Appalachian and Rocky Mountain ranges. The squirrels thrive at these higher elevations where there is an abundance of conifers (pines, spruce, firs, and hemlocks) which provide the cones that make up much of the squirrels’ diet. Red squirrels are also known as predators of young birds and eggs. Red squirrels are excellent climbers, allowing them to reach their food sources and to escape from predators.
What makes these images remarkable is that they were taken in Indiana, Pennsylvania by Lizoon’s friends Cindy and Gloria Vatavuk. This friendship was developed during Lizoon’s International Leadership in Education (ILEP) exchange program experience at Indiana University of Pennsylvania. This exchange and several others are sponsored by the U.S. Department of State and administered by IREX. Some of the values of these global exchanges are the long-term friendships and the collegial relationships that form after these face-to-face experiences.
While Pennsylvania is a neighboring state to Maryland (where this post is being written), the images came through to the blog from literally the other side of the world! This underscores the value of global education as a connecting point for teachers and students around the planet. We have a shared interest in learning about and protecting our global biodiversity!
Thank you Lizoon, Cindy, and Gloria for sharing these images and for participating in our global biodiversity forum!
Keeping an Eye Out for Dolphins!
July 11, 2019
Most people around the Chesapeake Bay typically think of blue crabs, oysters, and rockfish as the iconic species of the region. In recent years, scientists from the University of Maryland’s Center for Environmental Science have been urging the public to keep an eye out for a new visitor to the bay, Bottlenose dolphins! As sightings around the bay have increased, scientists are working to understand why these marine mammals are making inroads into the Chesapeake and its tributaries.
To facilitate the collection of data, a Chesapeake DolphinWatch app has been developed to help the public to share their sightings of dolphins in the region. To read more about the application and how to become involved in the project, click on the button below.
Schoolyard Wildlife and the Maryland Biodiversity Project
June 6, 2019
Students from Mrs. Ward’s class at Calvert Country School have been researching the wildlife that they have been finding on their school property. Data collected is shared with the Maryland Biodiversity Project, an effort to document the distribution of living things across the state. Through stream surveys and the use of trail cameras, the students have made a valuable contribution to our knowledge of wildlife distribution in our county and the state of Maryland! The students wrote up some background information on their findings.
From Jonathan: A common amphibian found in Calvert County is the Northern Two-lined Salamander. This salamander can be described as having greenish-yellowish or orange-blackish skin. It is 2 ½ to 3 3/34 inches long. It has a yellow belly. The Salamander lives in a wet habitat. The habitat has wetlands, streams, and rocks. The salamander’s diet consists of worms, bugs and other salamanders. This salamander sheds its skin. They tease their predator with their tail because it is detachable and will grow back. Salamanders are unable to hear sound. They use their tongue to smell and taste.
From Jonathan: One common mammal found in Calvert County and your school’s backyard is the raccoon. The raccoon can be described as having a robber mask for a face, a striped tail. It has short front legs and long back legs. They weigh about 10-35 pounds. The Raccoon lives in a wet marshy habitat. This habitat has swamps and marshes. Sometimes they live in suburbs because there is trash to get into. This mammal’s diet consists of fish, plums, crayfish, and berries. The raccoon is usually nocturnal and solitary. It is more active during the spring and fall. This mammal, at times, can be considered a pest. The public can call 877-463-6497 or visit the MD DNR website.
- Raccoons have thumbs
- Responsible for 60% of rabies
- They look like robbers
- Can transmit canine distemper to dogs
From Lucie: One common mammal found in Calvert County and your school’s backyard is the North American River Otter. The river otter can be described as having a long slender body covered in grown, waterproof fur. They range from 36 to 60 inches long from head to tail. They have sharp claws on their feet to catch prey. The river otter lives in a wet habitat. This habitat has streams, rivers, lakes, and fresh and saltwater marshes. This mammal’s diet consists of fish, frogs, crayfish, shellfish, and sometimes aquatic insects, snakes, turtles, salamanders, earth worms, small birds, and small mammals. The river otter is managed as a fur-bearing animal. The public can learn more about the fur-bearing management by visiting https://dnr.maryland.gov.
- They are the largest member of the weasel family.
- They live in a variety of habitats.
- They use dens made by beavers.
- They are primarily carnivorous.
From Khari: One common animal found in Calvert County and your school’s backyard is the Opossum. The scientific name is Didelphis Virginiana. The opossum can be described as having a long tail and a pouch to carry their young. The opossum lives in a woody habitat. This habitat includes dens in a hollow tree or under stumps and roots. This mammal’s diet consists of insects, frogs, worms, birds, fruits, nuts and carrion (dead animals). The opossum is usually nomadic, and they rarely establish their own territory. They are mostly nocturnal and wander throughout areas in the night to search for food. Opossum’s fake an illness to avoid predators. They also freeze to avoid predators. This mammal, at times, can be considered a pest. The public can call the furbearers hotline: 877-620-8DNR (8367) or visit the website: dnr.Maryland.gov/wildlife/pages/plants_wildlife/opossum.aspx.
From Khari: Another common mammal found is the Eastern Gray Squirrel. The Eastern Gray Squirrel is described as having gray fur and a bushy tail. They weigh from 14 to 16 ounces and are 9 to 12 inches. Their habitat range could be up to 40 acres of land. They construct their dens on bare or hollow branches. They also use abandoned bird nests for shelter. Since they’re predominantly a nut-eating species, they are found in many Oak and Hickory forests in North America. Their den (or drey) reduces heat loss. These squirrels feed on bark, seeds, walnuts, acorns and other kinds of nuts. They also eat beech nuts, pine seeds, maple samaras, wild grapes, and American holly berries. The Eastern Gray Squirrel will sometimes eat dog wood, black cherries, bird eggs and amphibians. They are alert, aggressive and inquisitive. They dig through snow to retrieve buried nuts. If there are any problems managing this animal please visit this website: www.animalspot.net/eastern-gray-squirrel.html or call the Nuisance wildlife hotline at: 1-877-463-6497.
Deep Sea Food Chains
Science in Action
June 3, 2019
Dr. Blaire Umhau is a former Calvert County Public Schools student who went on to study Marine Biology. She shares below some fascinating experiences conducting research deep in the Pacific Ocean. Thank you Dr. Umhau, for sharing your experience with us!
Exploration of the Deep Sea Food Chain
Dr. Blaire P. Umhau
In May, I went on an expedition with a team of scientists working to better understand the deep-sea food web. Scientists believe that animals living on the sea floor in deep (~4000 m) water need more food to survive than scientists estimate sinks to the depths from the surface waters. The food from the surface is in the form of tiny particles of organic material containing nutrients like carbon and nitrogen that these animals need to survive. Our goal was to determine what other food may be available and what the organisms are actually consuming. To do this, we used pumps to filter water and collect the particles that sink to the seafloor that deep sea animals will eat. We also collected organisms from the seafloor using the submersible Alvin. Alvin is a small submarine capable of diving to a depth of 4,500 m on dives that last up to 10 hours.
The specimens we collected have been taken back to labs on land to be analyzed. Hopefully, they will help us better understand how the deep-sea food chain works.
More from the American Chestnut Land Trust
May 7, 2019
Cooper shared: My favorite part of the field trip to the American Chestnut Land Trust in Calvert County was when our group got to work in the farm there. Half of our group was working on a technique of farming called hugelkulture. This is where you dig a hole, put in horse manure, old wood, mulch, compost, then mound dirt on the top of it all. The other half of the group were mainly weeding. I was in the group that was weeding. We had to weed a whole row of plants full of weeds to help the Daisy Girl Scouts that were planting sweet potatoes in that area. All the food planted there goes straight to food pantries to people aren’t as fortunate to get fresh food. The volunteers at the ACLT will harvest the plants, wash them, and put them straight on a truck to get them shipped, so they could be as fresh as possible. ACLT donates about 3,000 pounds of vegetables from this. I think this is a great thing especially since most of the workers are volunteers. One thing I wonder though, is what do they plant in these farms and give to the pantries. Going to the ACLT was a fun field trip and we helped to do a great cause.
Lillian reports: Our science class went on a field trip to the American Chestnut Land Trust, where we did farm work, searched for insects, and went on a hike. My favorite part of the trip was the hiking. I was fun to stop and look around as the guide told us things about plants and animals in the area. There were many difficult hills where everyone’s legs were hurting but we saw so many awesome things on the way. For instance, we saw a huge box turtle that our guide says was the biggest he had ever seen. We also saw a salamander chilling on a fallen log. It was also a great experience to work in the garden. I helped with preparing a section for sweet
potatoes to be grown. We had to clear weeds then put horse poop over top to put nutrients into the soil. Overall one of the best fiend trips from all of middle school.
Exploring a Local Land Trust
May 2, 2019
Much of the protected land in the United States is managed by federal, state and local governments. However, there are many natural areas that have been saved from development by forward thinking private citizens that work together to preserve areas of natural significance. The American Chestnut Land Trust (ACLT) in Calvert County, Maryland is one of these private sanctuaries. Recently, Mrs. Gallihugh brought her eighth grade classes to the ACLT to continue their studies of biodiversity in our region. Below are some of the reflections of her students.
Jasmin reports: My favorite thing that we did on the trip is going on the hike. We walked on one of their trails and went down to the creek. The guide spoke in depth about many of the different plants and birds that we saw and heard along the trail. It was fun being with friends and learning about nature. One of my favorite plants are the Christmas ferns, and I saw many of them along the trail. On one of the trees we found this leaf that gives off a scent when you crumble it up, and it didn’t smell that good. Down in the creek there is this old beaver dam. There were still some of the dam there but most of it had broken down over time. It was calming being in the woods; hearing the natural sounds of the animals in the woods. I did also like shoveling mulch when we got back from the hike. It was fun and I liked helping them out. I had spoken to the lady who was helping us out in the garden and told her how we do this stuff at our green team. She used to be the leader of the green team at her school when she went. I thought that was cool.
Taisiya observes: On April 29th, my class went to ACLT for a field trip. We went on a mile-long hike, farmed, and observed leaves. My favorite part of the field trip was going on the mile-long hike. We stopped every few steps to look at the different things in nature. Our tour guide told us that we could have seen snakes, beaver, plants, and many more animals. My group got see this leaf that smelled like spices, plants, a dead snake, and bugs. While we were on our hike, we went on this bridge that took us over leaves and water. Our tour guide told us facts and then we went back where we came from. When coming back from the hike it didn’t feel like it did when we started the hike. When I left I wondered: How long does it take for banana peels to compost?
Lindsay wrote: On April 29, 2019 I went to ACLT (American Chestnut Land Trust) for a field trip. My favorite part of the trip was the hike. I liked that we went hiking through the woods and we got to see many different things in nature such as learning about new plants, trees, and flowers and we also got to see a beaver dam. I learned that Mrs. Gallihugh’s favorite plant is the “Jack in the Pulpit”.
Kyleigh shared: My favorite part of the field trip was the hike where one of the workers told us about the different types of plants found along the trial. When we first got there, we were split up into 3 different groups. My group went to their garden space to dig holes so they could plant their crops for the summer. Then my group went over to the barn and picked bugs out of water from the streams and recorded how many we found. The last thing my group did was walk on the trails while the worker explained what types of plant were on the trail.
Alexis observed: On April 29, 2019 my science class and I went on a field trip to the American Chestnut Land Trust and did many things involving the biodiversity in our ecosystem. The things we did consisted of searching through leaf bags filled with many different insects of many species, going on a hike on a trail and looking at the many different plants and/or native plants, animals, and just our ecosystem. We also conducted a type of farming called hugelkulture it was something I’ve never done or heard before so it was interesting to do. Hugelkulture is when you dig a hole in our case it was a 4x2x2 foot hole, and once you dig the hole you put horse manure, wood chunks, mulch, and dirt in it and wait for it all to
decompose. Once decomposed it turns into a very rich soil superior for farming. Overall I think it is great what the American Chestnut Land Trust (ACLT) is doing for our economy and I for one had a fun time experiencing it.
Ryleigh observed: On April 29 we went to ACLT. We did many things on this trip. My group started off searching through the leaf bags trying to find bugs. At first this wasn’t very interesting but once we started find different bugs and watched them it was very fun. Then after that we went on a hike for about an hour. We stopped every few feet to look at the scenery and our tour guide taught us about the plants and animals around us. After that we worked on the farm. This was my favorite part of the trip. I used the wheel barrel to bring the mulch and then my classmates spread it around the flowers. After we had finished that a classmate and I weeded out the gardens getting ready for the potatoes to be planted. At the end the leader told my friends and I that we would be terrific “flower girls.” It was very fun and I’m glad that we could help the ACLT while having fun and learning about our Earth.
Chase tells us: It was a cold day in late April. My class went on a field trip to ACLT. We did many things on this trip, such as, going on a hike, digging a hole to make richer soil, and trying to find different species in water. In my opinion, the best part was probably the hike. This is because it was very cool to see all the different types of plants. On the hike, we saw poison ivy, Christmas ferns, and much more. The Christmas ferns were probably the coolest plant. This is because it’s a fern that has leaves that look almost like stockings from Christmas. This is why its called the “Christmas fern”. This type of fern doesn’t harm you or start a rash like a poison Ivy plant does.
From Griffin: For our field trip to the American Chestnut Land Trust we had activities to do like for example, working with mulch by moving it from a pile. My favorite part of the trip was when we observed leaf packs to find aquatic bugs in water. This was my favorite part because I got to see what we could find and it was enjoyable. The bugs also got to show us the quality of the water because of the kind of bug that is in the water, for example if Stoneflies and Mayflies were in the water then the quality would be good. For my group we found Caddisflies, Stoneflies, and Mayflies and some Scuds were in the water too, meaning the water was high quality.
Bio-Blitzing for a Purpose!
April 26, 2019
We encourage students to learn about the world around them. Students enjoy the opportunity to get out of the classroom and explore the natural environment surrounding their school buildings. These adventures are not only great learning experiences, but also can yield some valuable data for larger scientific studies. Students in Mrs. Gallihugh’s classes at Mill Creek Middle School recently conducted a “Bio-Blitz”, recording all of the living things encountered during their outdoor survey. This data is being shared with the Maryland Biodiversity Project, an effort to document living things across the state of Maryland. Below you can find some student writing samples about their work and some images captured during the bio-blitz.
Veronica shares: After visiting the Maryland Biodiversity Project website, we realized there weren’t many species of wildlife and plants observed in the Solomon’s Island quad. Because our school is in said quad, we went outside in hopes of discovering and observing species to fill in the gaps of data between our quad and the surrounding quads. Students were equipped with cell phone cameras, so that the variety of species found at Mill Creek could be documented. One of the species of wildlife found was a worm snake. The worm snake was found after turning over a few rocks in a drainage ditch. We hypothesize the worm snake was found under a rock because that is where it’s main source of food could be found. We also came to this conclusion because a variety of bugs (mostly ants) came rushing out upon the rock being turned over. This leads us to believe that worm snakes prefer ants over other types of foods.
From Beau: In science class, we were exploring biodiversity in our ecosystem. To do this, we went on the Maryland Biodiversity Project website. Once we went on to this website, we located our quadrant, the Solomon’s island quadrant, and looked at what data was missing. Once we did this, we tried to fix that by going outside and searching for the missing animals in our quadrant. Some of the animals we found consisted of…
Savannah writes: My science class went outside to find different species in our school ecosystem. Our class then uploaded the pictures we took of species and saved them in an MCMS album on Schoology. We then decided to identify some of the species we found using apps like Seek and iNaturalist. This is one of the species we found in Mill Creek Middle School in Solomons, MD.
Chase reported: It was a sunny day in April. My science class decided togo outside and look for any types of species found in the back of our school. Before this, we had visited MarylandBiodiversityProject.com and found that not many species are recorded in our quadrant, which is the Solomon’s Island quad. We went into the woods and we found many different types of species such as, worms, snakes, and different types of trees and plants. While outside, we found a worm snake. This snake was found under a rock which we picked up. The snake was slippery and very tiny, it also seemed very calm when we picked it up and had no problem with us taking it out of his home.
Jamie wrote: In my science class we went on a bio-blitz through the woods at our school. The woods that we searched through was in the Solomons quadrant. A bio-blitz is an activity where you go into the woods to explore for animals and other living things. Prior to going outdoors to find animals in our quadrant we visited the Maryland Biodiversity Project website to see how many species are reported in our quad. There are only a few species reported in our quad. In our quadrant we have animals such as salamanders, salamander eggs, snakes, spiders and deer.
Hunter said: On April 12, 2019 our class went outside to conduct a BioBlitz experiment on the school grounds. During the previous class (April 10) we set up a frog recorder to help us gather sound to determine which frogs live in the area. However, we weren’t here to examine the sound data. A BioBlitz is when you go outside to collect as much data as you can in a limited amount of time, then examine it. An example of plant life that we found was a Wild Violet. A Violet is a “lawn weed” with beautiful purple petals. Another lawn weed is the dandelion. A dandelion is a weed with yellow petals.
April 15, 2019
The sounds of nature reflect the health of our local biodiversity. Through a generous grant from the U.S. Department of State, we were able to purchase some equipment to help gather sounds illustrating the biodiversity from a partner school located in Calicut, India. Teacher Sujith S. set up the Song Meter 4 recorder at the Aralam Wildlife Sanctuary located in Kerala in the southwestern part of India. This recorder captures one minute sound samples every half hour. The collected sounds help to document the biodiversity of the area. Students in Calvert County, Maryland (US) will share sounds collected through their own biodiversity studies. These sounds will also be posted on the Global Biodiversity Blog as a way to celebrate the richness of the soundscape of our Planet Earth! Stay tuned.

In this recording you will first hear the call of the Small Green Bee-eater. At :17, listen for the Black-rumped Flameback or Lesser Golden-backed Woodpecker to make a loud call as it flies past the recorder. The sound made by members of the woodpecker family is similar around the world!
In this pre-dawn recording, listen for the Racket Tailed Drongo to call throughout the segment. Turn your volume up a bit and try to hear the Jerdon’s Nightjar at :05 and :08 seconds. The call is a distant and short “cough” like sound.
See if you can pick out the Srilankan Frogmouth call at :30 and :49. These last two birds are related to the Whip-poor-Whill and Chuck-Will’s Widow that can be found in the United States.

Many of us think of deserts as barren wastelands colored only in shades of brown or gray. The desert comes alive following winter rains and there can be a burst of color and activity as desert flowers begin to bloom. This year in southern California, a so-called ‘Super Bloom’ followed a rainy winter season. These blooms are followed by the mass emergence of many butterflies and caterpillars that feed on this profusion of plant growth.
Our friend, Rick Froehbrodt, a fifth grade teacher at the Franklin Elementary STEAM Magnet School in San Diego, shared some images of a recent trip into Anza Borrego State Park. His student, Kayla N., wrote up a nice description of the park to accompany Rick’s images. Thanks Rick and Kayla for a great post!
The Anza-Borrego Desert State Park is the largest state park in California. It is 25 miles east to west and 50 miles north to south. It was named after a Spanish explorer, Juan Bautista de Anza and Borrego, the Spanish word for sheep. It’s located in the Colorado desert of southern California. In the summer the temperature can reach 110 degrees or more. In the winter it decreased by 40%. Many visitors come to the Anza-Borrego for their beautiful wildflowers such as the verbena and lilies.

While we think of owls as inhabitants of deep dark forest landscapes, there are some species that can be found in close proximity to human activity. In fact, there are some species that thrive in the heart of the city! Our friend, Lizoon Nahar from BAF Shaheen English Medium School in Dhaka, Bangladesh, shared some student work about an owl observation in an urban setting.
This small and stocky Spotted Owlet, binomially named ‘Athene brama’, is from the Animalia Kingdom and Chordata Phylum. They can be found near human habitation because of the increased availability of rodents over there to feed the young. They breed in Tropical Asia between November and April, and perch in quite small groups in the dent of trees or in the holes of rocks or buildings. A variety of insects, for example, small invertebrates, scorpions, molluscs etc. are hunted by them.
In spite of being nocturnal, meaning that they are active at night, these owlets can sometimes be seen during the day. A fascinating behavior of them is that, if anyone disturbs them from their daytime place, they jerk their heads and simply stare at the intruders.
Spotted Owlets are very familiar to people, mostly because of their call which is a loud and harsh churring and chuckling chirrur-chirrur-chirrur ending with a chirwak-chirwak. Many people have linked them with bad omen too.

A Bio-Blitz is a wide ranging survey of biodiversity in a given area. All living things that can be documented are recorded and shared using a variety of different apps that support this effort. Mr. Cook from Plum Point Middle School located in Calvert County, Maryland (U.S.A.), shared his students’ experience with a Bio-Blitz.
Back in December, students in Mr. Cook’s 8th grade Science class participated in a BioBlitz using the apps Seek and iNaturalist. Here is what some of the students had to say about the experience.
“Do you think the ecosystem is diverse at PPMS? My first period class went outside on the cold Tuesday morning to find out, we went out and looked for organisms to find to determine if our school’s environment was diverse depending on how many different organisms we found. We found a total of 15 organisms in our school’s ecosystem just in our middle school’s backyard! After we identified some organisms, the next day we went into groups and discussed all the organisms the classes had found. We attempted to identify some of the unknown organisms, but we did not have much luck. We did find something interesting, someone had found a worm and an ant. We were mainly shocked by the worm because when we were out, we could not find any animals, especially a worm because of how cold it was. We did think the ant was a possibility that we just did not find because of how small ants are. One other observation that was cool and interesting was the mountain laurel which is a kind of flower, I only found this strange because there were three identifications of those, but I have never seen the flowers growing so it will be interesting to see them growing in spring. The ecosystem at PPMS is diverse according to the observations because all the things found seemed balanced and none were taking over, and none were dying out. So, to think about how 99% of the things we found were only in 6 hula hoops out of the whole back yard of our school, PPMS is a diverse ecosystem.”
“Have you ever wondered what the ecosystem of your school was like? On Tuesday, Dec 4, Mr. Cook’s 2nd period went outside to observe the different species living in the schoolyard. The day was very overcast, windy, and cold. The students got into groups of 7 to walk around and discover the different species living around them.
As my group went to the first hoop, we found many types of mosses and leaves and recorded them on the papers given to us. Moving to different hoops, we began to find more of a variety of plants and animals living in the schoolyard. There were different trees and bushes all around the school that we were able to identify using the Seek and iNaturalist apps. In some hoops, there were small insects that were discovered when looking closely at the plants in that area. Most of the insects that were found were small, like ants, but some worms were also discovered in the ground. Something interesting about observing the plants and animals was that we could see specifically what species live around us every day. It was very difficult to find a lot of different organisms because of the current season. Because it is almost winter, most of the species have left to find warmer areas or have died from the temperatures.”
“Have you ever looked out your window to see plants? Of course, you have! But, have you ever studied the plants closely? Recently, my science class and I went outside to observe different plants and organisms. We found a wide range of plant species. One observation that we made was we found an Eastern Redcedar, it is a small tree. It has long pointy leaves and many branches. Another observation is a Japanese aucuba. This bush is very large compared to the Eastern Redcedar. It has dark and light-colored leaves and is very pretty. Also, we found it shocking that we were able to find so many plants in one area and many different types of plants! We also found a Japanese Honeysuckle, a little plant with four large leaves or stems. We found many more. We used the app “Seek” to identify the different specific species. I learned so much about my local ecosystem and the organisms living in it. I am very happy to say my local ecosystem has very good biodiversity. Having positive biodiversity means that when a natural disaster or any life-threatening issue occurs, there is more room for animals to change and cope with their new ecosystem, or with the loss of an organism within their food chain or ecosystem. I encourage you to go and study your local ecosystem and see whether it has a good biodiversity or a bad one. #Study your local Ecosystem! #BeOnewithyourBackyard”
“…Then the next day we stayed inside in order to identify all the species that we took pictures of. We identified the moss as a fern moss and the fungi as black knot. Then we identified the worm as a common earthworm. We have found that the biodiversity in your backyard may not be the best but there are still many important living factors in your very own backyard. This shows us that the health of our ecosystem is not good because there’s not much biodiversity.”
“In class the next day, we set out to identify all the species that we could from the previous day. Out of all the species posted on the app, 15 were successfully identified. There were still many unidentified species and work to be done. It was sometimes difficult to identify the organisms in the photos because there were often many species that’s appearances matched the photos. Using the iNaturalist app, we were able to get feedback on the photos from different people. Some were specialists in the organisms, while others just knew what the species were by looking at them. It was interesting to see the different species of plants that we often just group together as “trees” or “bushes”.
By going through the process of identifying various organisms in the schoolyard, I can conclude that there is a wide diversity of plants, but a low variety of animal species. Biodiversity is important because, by seeing the animals that live there and what conditions they need to survive, you can define the current conditions of the ecosystem. I’ve discovered that you can learn a lot about the ecosystems around you by spending time looking at the different organisms that live there. In using the iNaturalist and Seek apps, we could easily and quickly get access to feedback on the species that we took pictures of.”
“I found It very interesting and slightly exhilarating when I identified a species. I felt proud and like a true scientist which was fun. On the other hand, it was very cool to look around the environment that I am surrounded with and pass daily. My only wish is that we had had more time for the identifying part of the activity.
It is important to consider the biodiversity of an ecosystem because one ecosystem could affect other systems around the world. Biodiversity helps humans in ways I would’ve never imagined. I never realized the impact that ecosystems have on medicine and the life of humans on this earth. One small species going extinct from a natural disaster- for example- could end up being catastrophic. One species dying affects an ecosystem’s food chain, affecting which species live and die, potentially leading to the destruction of an ecosystem. Also, if this isn’t enough, one ecosystem’s deceasing could affect the others. All of this leads back to the way that humans are affected. Without biodiversity the entire world is at risk and is not stable. We need biodiversity for the well-being of this planet and the development of our society.”
“The next day, we used iNaturalist and Seek to identify organisms. We compared the pictures we took with the pictures of other already identified organisms suggested by iNaturalist. We identified a few of the same organisms and had about 10 different species that we identified. I found doing that very interesting. Overall, it was a very interesting experience to search for then identify organisms around my school. If there is ever a BioBlitz near you, I recommend trying it out. There is a very interesting connection between the biodiversity and the health of the ecosystem and what it provides for us through that.”
The students that participated had mixed success in finding species in the beginning of the winter months, however they did gain a better understanding of biodiversity’s important role in our school yard ecosystem. We’re looking forward to repeating this activity in the spring and are anticipating even better results!
Pied Mynahs in Bangladesh
March 11, 2019
This article was written by a student of Lizoon Nahar of the BAF Shaheen English Medium School in Dhaka, Bangladesh.
The lovely flowers of every garden start their wonderful day with the sweet music of the enchanted bird: the Pied Mynah. In Bangladesh they are known as Shalik . It is an open woodland bird which has adapted itself to the urban environment. The Pied Mynah is identified by the brown body including white stripes, black head consisting bare yellow patches behind the eyes, yellow beaks and brown legs. These birds feed on small insects, earthworms, seeds, grain, fruits etc. The Pied Mynah loves staying in artificial nests or nests built in wall holes. If you leave a shoebox on your roof, within a few days you may find small birds peeping from within it. It has been recorded that these birds are quarrelsome at times but still, they are able to take a fond place in people’s mind.

Birding with Children
March 8, 2019
Children are born observers. They are fascinated with the natural world around them and animals are often a particular focus of their interest. Our friend and teacher Sujith S. from Kerala, India, took his own children out for a Saturday afternoon bird walk. In addition to watching birds, they spent some time conducting some field sketches of their observations. This is a great skill for students to develop!
Show us Your Squirrels!
February 26, 2019
Squirrels are a diverse and widely distributed group of animals. Since they often live in close proximity to humans, they are easily studied and a provide a great example for us to look at ways in which a closely related family of mammals varies from place to place. We invite ALL of our participants and readers to submit posts about your schoolyard squirrels. It will be interesting to see the diversity of these creatures across our globe!
Thanks to our friends at BAF Shaheen English Medium School in Dhaka, Bangladesh and their teacher Lizoon Nahar for submitting the first post in our recurring “squirrel series”!
Squirrels in Bangladesh
Among the lush greenery of Bangladesh dwell nimble, bushy-tailed rodents, called squirrels. They are members of the Sciuridae family and can be divided into about two hundred species. However, only about nine of them can commonly be encountered in this country including three-striped squirrels, five-striped squirrels, black giant squirrels, Irrawaddy squirrel and orange-bellied squirrel.
Three-striped squirrels are the most common species, living in Bangladesh. They are mostly found in the hilly territories of the country with some of them living east of the Jamuna river. This gray-brown coloured squirrel has a creamy white-coloured belly and three stripes that run from their head to tail. Three-striped squirrels are majorly frugivorous but also feed on nuts. They are quite noisy and make a “chip chip chip” sound when they sense danger. They are carpetbaggers in urban areas, and can be easily curbed and tutored to accept food from humans. These rodents aid pollination and dispersion of fruits and seeds, thus contributing to the ecosystem and preserving the country’s greenery.
However, forests and trees are gradually being cut off to accommodate the rapidly growing population of the country. As a result, the squirrel population is decreasing as they die due to a lack of food and shelter. If this continues, squirrels in Bangladesh will soon be lead to extinction which will affect the country’s whole ecosystem. So, ensuring a safe natural habitat for these squirrels has become almost obligatory.

A Schoolyard Biodiversity Survey in Pakistan
February 15, 2019
In the second week of February 2019, the fourth graders of OPF Girls College in the capital city of Pakistan were given a project to observe their environment and study different creatures by their English language teacher Ms. Irum for whom the activity was a part of CLIL i.e. Content and Language Integrated Learning. Here the content was related to the science field. The students came out of their classrooms in the form of groups. Their writing skill in the second language was supported by such tactile and kinesthetic way of learning. The groups chose a specific area for their study.
One of the groups said in their observations that they really liked touching different plants. It was mentioned in their writing that they saw plants with big leaves, found snail shells and baby termites. They need fertile soil to grow. They claimed that some leaves were thorny, hairy and simple. Some flowers were grown in a vehicle’s tires.
One of their first observations was a Coffee Bee Clearwing, a type of Hawk Moth. These insects will hover in front of flowers as they feed on nectar.
They mentioned that the whole group was amazed by tiny creatures which looked like termites. It had holes all over its place. It was not only one. It was the whole colony of it. The soil was wet which proved that it liked damp places to live in.
They called it a ‘rare insect’. In its description they wrote: It is as small as an ant. It had orange head with white transparent body. It had one black eye and two black antennas. It had difficulty in moving which showed that they were newly born babies. At times, it rolled upside down so its movement stopped. This is likely a “soldier” termite, a defender of the termite colony!
Another group had their findings near a tall tree.
They discovered a bug. They called it a ‘black bug’. They claimed that it was changing its head’s color, it had six legs and there were three lines on it.
The second discovery of the same group was a caterpillar found at the same place. They called it a slug which they thought as slimy, flexible and had no bones.
Another group was found working on the bushes. They tried to find things in depth. They even drew what they saw.
Their most important discovery was the ‘green potato bug’ with sticky legs and red eyes. They mentioned in their writing that the bug was in green color because it was on green plant. It was camouflaging itself from big creatures.
A few groups worked on snail shells which were found in abundance.
They found a family of snail shells at different places. Some were sleeping in the mud and some were sleeping on the green plants. One of the snail shells was of red color which looked different from the others. The students relate a shell’s body structure with a ‘hypnotizing machine’. They had a spiral shape. These appear to be specimens of a group of land mollusks known as “tramp snails”.
Looking for an Environmental Research Project? Try a Stream Survey!
February 11, 2019
A few weeks ago, we described the results from Mill Creek Middle School’s eighth grade stream survey. This is a project that could be replicated anywhere in the world that has flowing streams. This is a great way to engage students in an authentic assessment of environmental health. Jonathan, a student at Calvert Country School, was kind enough to put together some step by step directions for a leaf pack project.
How Can we Determine if a Stream or Creek is Healthy?
One way to determine if a stream or creek is healthy is by conducting a leaf pack experiment. This experiment uses tree leaves and aquatic insects to evaluate the health of a stream or creek. Before starting the experiment, you will need a stream and some materials.
First, find a location along the stream that has good water flow and is deep enough for the leaf packs. If the stream flows too fast, some organisms cannot hold on to the leaves.
Second, gather the materials needed.
- Mesh bags
- Nylon string
- Flagging tape
- Zip ties
- Plastic totes
- Ice cube trays
- Hand lenses
|Next, prepare the leaf packs. To prepare the leaf packs, collect fallen dried leaves from the ground. Use the scale to weigh 30 grams of leaves for each mesh bag. Tie 3 bags together with zip ties. Take a long piece of nylon string and tie it into the mesh bags.|
Once the leaf packs are ready, tie the leaf packs to rocks or roots. Make sure all leaf packs are under water and secure.
After several weeks, retrieve and process the leaf packs. *Before retrieving the leaves, collect stream water or tap water (allow tap water to sit for 3 days)*.
Pick up the leaf packs quickly and place into a large plastic tote. Bring the leaf packs inside to process. Place the leaf packs into a bucket of the stream or tap water.
Shake small handfuls of leaves in the bucket to get the macroinvertebrates off the leaves. Pour the water from the bucket into a strainer to catch any insects.
Put a small amount of water into the ice cube tray and use a spoon to catch and place a macroinvertebrate into each section.
As a final step, identify each macroinvertebrate found and record on a datasheet. Study the data to figure out if the stream is in poor, fair, or good health.
Nature Spotting Contest Winners!
February 6, 2019
Some sharp-eyed students and teachers were able to spot the hidden animal in the photo from the January 30 blog post. The animal is a raccoon, a fairly common species throughout much of North America. Raccoons have also been introduced in Europe and Asia an may be quite common in some areas.
Congratulations to Cameron, Michael, Asa-Marie, Amiya, and Olivia from Mrs. Gallihugh’s class at Mill Creek Middle School for submitting their observations. Thanks also to students from OPF Girl’s College in Islamabad, Pakistan for submitting the photo below!
Look for more biodiversity related contests in future posts!
Nature Spotting Contest
January 30, 2019
We are surrounded by biodiversity. The plants and animals that make up our local ecology can be seen as soon as we step outside our doors. Animals can sometimes be trickier to spot, as they often would prefer not to be seen and blend in with their surroundings.
For this contest, we are asking classes to look at the photo below and spot the hidden animal lurking in the picture.
The first class to send in a screen shot with the animal circled and identified, will win a certificate for the “Eagle Eye” award and recognition on the Global Biodiversity Blog! Send your screenshot to: Eagle Eye Award. Good luck!
January 24, 2019
Our friend Rob C. recently traveled to Uganda on an expedition to study the reptiles and amphibians of this East African nation. The group took a side excursion to look for Mountain Gorillas in the Bwindi Impenetrable National Park. The trip did not disappoint as several of these magnificent apes were observed by the team.
The Bwindi Impenetrable National Park is a UNESCO World Heritage Site. These are places of natural or cultural significance that have been identified by the United Nations are places that are important resources that need protection for the good of all humanity.
Mountain Gorillas are critically endangered. This means that without protection, it is very likely that the species would go extinct. There are approximately 1,000 Mountain Gorillas remaining in the wild. This is actually an increase over the past 30 years and it is hoped that this population increase can be sustained.
The Pine Tree: Ordinary-Extraordinary Beauty
January 16, 2019
The students from Ms. Irina Azarova’s class of the Roshchinski State School in the Lipetsk region of Russia submitted an excellent article about their study of pine trees.
We study at Roshchinsky school, it was built in 2001 and immediately the question arose about its landscaping. Near the school, flowerbed, lawns, an orchard appeared, and then they decided to plant several pines. One was planted directly opposite the entrance to the school.
A pine is the oldest tree on earth. A pine was a symbol of life among the northern peoples, a symbol of fertility and immortality – in Asia, eternity and longevity – especially in Japan.
An ordinary pine is found everywhere. It can grow like a ten-storied house. Pine’s resin was used not only for medical purposes, but also for gluing household items, arrowheads and spears.
In Russia, the resin was used as glue, people burned it to illuminate the streets. Currently, products derived from pine are used in 70 industries, without them it is impossible to manufacture paints, plastics, paper, photographic films. In Russia, pine’s sap was chewed to strengthen the gums, teeth, and also to disinfect the mouth and throat. Pine phytoncides disinfected the air in the forest, which became almost sterile and was used to house various kinds of health centers and sanatoriums.
The nature of our land is rich and beautiful. We are very interested to learn about it something new. When we are in the forest, we are surrounded by various trees, especially pine trees look majestic and mighty. Glades around pines strewn with cones. We wanted to learn more about the pine tree, what role it plays in nature and human life.
1.1 Pine is a common widespread tree of Eurasia, starting from Spain and the United Kingdom and reaches the Amur River in Eastern Siberia. In the north, pine grows up to Lapland, in the south it is found in Mongolia and China. It forms clean plantations and grows with spruce, birch, aspen, oak. It is undemanding to soil and ground conditions, and often occupies areas unsuitable for other types: sands, swamps. Pine is adapted to different temperature conditions. It is distinguished by its love of light. In the north of the range rises to a height of 1000 m above sea level, in the south to 1200-2500 m above sea level.
The tree is 25–40 m high and with a trunk diameter of 0.5–1.2 m. The tallest trees (up to 45–50 m) grow on the southern coast of the Baltic Sea. They live up to 150-200 years, sometimes up to 400 years. Pine ordinary grows rather slowly, so it will take more than one decade until it reaches 20-40 m. This is the height that an adult plant reaches. Young pines have a cone-shaped or rounded crown, with wide branches. In old trees, the crown becomes umbrella-shaped.
The trunk is straight, below with dark brown bark, above – with red-brown and golden bark. The bark in the lower part of the trunk is thick, scaly, gray-brown, with deep cracks. In the upper part of the trunk and on the branches the bark is thin, in the form of flakes (flakes), orange-red.
Leaves are in the form of needles. The needles are smooth, sharp, rigid, fastened in pairs, retained on the branches for 2–3 years, 4–6 cm long, 1.5–2 mm thick. Gray or bluish-green, as a rule, slightly curved, the edges are finely toothed, live 2-6 (-9) years. In young trees, needles are longer (5–9 cm). Old needles are shorter (2.5-5).
Pine, like all coniferous plants, has no flowers. Male cones are 8-12 mm, yellow or pink. Female cones are 3–6 cm long. Cone-shaped, symmetrical or almost symmetrical, single or 2-3 pieces. When ripe, dull cones from gray-light brown to gray-green. Ripen in November – December, 20 months after pollination; open from February to April and soon fall. The scales of the cones are almost rhombic, flat or slightly convex with a small navel, rarely hooked, with a pointed tip. The seeds are black, 4-5 mm, with a 12-20-mm membranous wing.
Pine is the source of many substances and products widely used by man. Essential oils, turpentine, rosin, varnishes, solvents, adhesives and other products are obtained from the resin. The amount of tar and turpentine depends on the age of the trees, the nature of the soil and climatic conditions. Rosin obtained in the processing of resin, is used in soap-making, paper, rubber and paint industry. It is also used for rubbing bows and strings of musical instruments. In addition to the benefits that these trees bring, the pines look majestically and greatly decorate the landscape. They are often planted near dispensaries and sanatoriums, administrative buildings, used for landscaping parks, country estates.
1.6 Healing properties
In addition, the plant has a healing effect, since it releases into the atmosphere a large number of useful substances that suppress many pathogens.
Therefore, walks through the coniferous forest are useful to everyone without exception. Curative conifer air favorably affects the nervous, immune systems, respiratory tract. In the treatment of many diseases, young, fresh needles, cones, buds, shoots, bark and resin of the tree are used. In particular, young needles are actively used in the treatment of colds, flu, respiratory diseases.
In Siberia, curative tea for colds is prepared according to this recipe: you need to pour 100 g of fresh pine needles and young shoots with a liter of boiling water, boil again, immediately remove from heat. Wrap the pan warmer and insist until it cools (turns warm). Then filter the drink, mixed with honey and take 100 ml, several times a day.
In China, pine is considered a tree that brings happiness. Therefore, it is often planted near private houses, as a symbol of well-being, good health and longevity.
In Russian, there is an expression: “Lost in three pines”. This means not being able to find a way out of a fairly easy situation.
Our pine tree gives an aesthetic appearance near the school, it is beautiful and stately, as it has enough light and nutrients, its crown is wide. But the pine was planted not only to decorate the schoolyard, but also so that we would decorate our green tree on New Year’s holidays and learn more about this tree.

Some Rwandan Monkeys
January 10, 2019
Monkeys are an interesting part of our global biodiversity. Our friend and educator Robin Shaffer recently traveled to Rwanda and spent some time in Nyungwe Forest National Park, where he observed four different species of monkeys.
Thanks Robin for sharing these awesome photos!
Baboons are relatively large monkeys, some of them reaching a weight of over 70 pounds (32 kilograms). Baboons are omnivores, meaning that they eat both meat and plant material. Baboons live in complex social groups or troops that may include dozens of members.
Vervet Monkeys range over much of east Africa. These are smaller monkeys, typically weighing less than 10 pounds (4.5 kilograms). These are long lived monkeys, often with a life span of 30 years. In many areas, Vervet monkeys are considered pests as they will steal food and raid crops from farms.
L’Hoest’s Monkeys are beautifully marked with black and white fur. These monkeys spend most of the time on the ground, where they live in small groups consisting of a single male and 10-15 females and offspring. The are primarily plants eaters although they will consume some insects and other invertebrates.
The Colobus Monkey is another beautiful species of east Africa. While the adults are covered in long black and white fur, newborns are completely white. Colobus have an unusually tiny thumb, which is essentially a stump. The other four fingers are extra long however, enabling them to easily swing through the branches of trees. These monkeys are the most arboreal (live in trees) of any African primate. Colobus are important to the ecosystem for seed dispersal as they are reported to be “sloppy” eaters, scattering the seeds from the fruits that they eat throughout the forest ecosystem.
Every Stream has a Story to Tell
January 7, 2019
The small streams that flow through our backyards and communities can reveal a lot about water quality and environmental disturbance. CHESPAX staff visited eighth grade classrooms in the late fall of 2018 to conduct stream surveys using aquatic insects as indicators of stream health. Here are some reflections of students from Mill Creek Middle School on their findings and their impressions of the experience during the investigation. We will be adding more blog entries from Mill Creek over the coming weeks!
Alaura writes: We did a stream survey with CHESPAX who provided the materials. My class and I pulled dirty, muddy leaves with critters in them and put them in a container of water. We then searched for the critters we could find in the mucky water and when we did, we set them into ice cube platters. We found bugs like scuds, mayflies, stoneflies, crane flies, and hellgrammites. We recorded our data on a chart and determined our score.
From Alexis: There are little streams all around you though you may not notice them. There are little organisms that live in those streams. When it rains and the environment is polluted the runoff goes into the streams affecting the little organisms (Benthic Macro-Invertebrates ‘BMI’). IN my science class we wanted to know how healthy our local streams are, so we did an experiment. Some bugs tell us the water quality is healthy/good. While other (BMI) tells us the water quality is polluted and poor. We pulled some leaves in bags out of the stream and studied the water. We found many (BMI) leading us to know how our environment Is affecting our local streams.
Kara adds: In my class we were looking for bugs, more specifically macro-invertebrates. We were looking for these to see the variety of macroinvertebrates that we have living in our own stream (St. Leonard creek at Flag Ponds and Mill Creek.) One thing we discovered was a gilled snail. A gilled snail is a good sign as these are sensitive to pollution. If you find a gilled snail in your stream that means that it is healthy. It’s also a good thing to have variety in macroinvertebrates that you have living in your own lake stream. We also took some pictures of the insects that we found in the leaves.
Autumn observed: The St. Leonard Creek at Flag Ponds is a healthy creek. When we took a look at the data that the stream provided us, we found many different kinds of benthic macro-invertebrates that told us a lot about it’s great biodiversity. This biodiversity proved the good health of the creek based on the variation of these macro-invertebrates.
Beau learned: One Insect that we found while researching was a Hellgrammite. The Hellgrammite is a predator of macro-invertebrates that can resist moderate pollution. The Hellgrammite shows that the ecosystem is flourishing because if there is no prey, the predators will leave as well. So if there is a predator, there is prey to go with it.
Catrina found out: On December 11th, CHESPAX brought mesh bags filled with leaves to our school. Those bags of leaves had been sitting in St. Leonard’s Creek in Lusby, Maryland for a month before they brought them here. They dumped the leaves into buckets with water, gave us tools, and had us search for bugs who had made their home in the leaves. The groups of kids found many bugs, and even a salamander, throughout the leaves. Through this we determined the heath of the creek from our findings. For the St. Leonard’s Creek, the creek heath was 22 which is “good”. These are some of the bugs, or benthic macroinvertebrates, that our classes found.
Adapting to a Changing Climate: How can we support our backyard birds?
January 2, 2019
Climate change is impacting wildlife around the world. Arctic species are finding that the year-round sea ice to which they’ve adapted over thousands of years, is no longer present. Intense storms batter coastal areas and alter the landscape, impacting critical habitat.
In Khamgaon, India, a town in in the Vidarbha region of Maharashtra state, the intense heat in April and May, coupled with a lack of rainfall has created a dire situation for wildlife species. Large cats such as leopards will sometimes venture from forested areas into villages in search of water or food. Teacher Rajesh Patil has worked to create an oasis for birds in his yard through creative plantings and by providing water sources for some of the birds local to his region. Along with Gerard Francis and Sreedharan Gopalsamy, Mr. Patil wrote an excellent article describing his project in a recent issue of Nature Watch magazine
As we work at adapting to a changing climate, it is worth considering our wild neighbors and to help provide them with a means of survival in an altered landscape.

Creature Feature: Bougainvillea glabra
December 21, 2018
This post is from Students Ngan at 11A5 classof Mrs Linh Truong at Binh Thuy High School in Vietnam.
Bougainvillea glabra is flower in the Nyctaginaceae family. They are a beautiful flower, which is native to South America, but now they are grown in Vietnam. The plants bloom in all seasons. If we know how to care for it, this flower will bloom very beautifully. On the other hand, it is a climbing plant. People usually grow it on a gate or fence, so it is very beautiful in all seasons.
The plant originates from Central America and South America. It is grown often at offices, cafes or in the park and at homes in urban areas. This is a healthy, beautiful and easy to maintain species valued by both artisans and any people.
The stem is over 500 centimeters. Bougainvillea glabra are creeping plants with many branches. Flowers are single, oval or elongated at the top, round at the root. The leaf stems have thorns in the leaf axil, which are straight and pointed.
Blooms grow with a cluster of three flowers, each attached on a white or pink leaf which is very beautiful.
The growth rate of flowers is fast and they grow towards light, demonstrating positive phototropism. Bougainvillea will develop in good drainage conditions, with adequate nutrients.
Creature Feature: Domestic Dog (Canis lupus familaris)
December 21, 2018
Domestic dogs are associated with humans all around the world. Mrs. Linh Truong shared some insights about the local dogs in Vietnam.
Canis lupus familiaris (Little Canini) is a species of Canis lupus in Caninea familiy. It is a species of Phu Quoc island. Canis lupus familiaris have tiger bridle, fire gold, transfer ink with the fur is darker in back, ears upright and slim waist. Additionally, they grow with a size of average 55 centimeters, a weight of 18 kilograms.
They have great hunting ability. Canis lupus familiaris can hunt big game, such as deer, wild boars and snakes. They have risked their lives to save the owner anytime when they are danger.
utstandingly aggressive compared to the other dogs, they fought and did not falter in despite of their larger rivals and it often won. It can track the prey even when they has passed long ago. They often back even when they are lost a few days.
Whenever they discover prey, they send prey to the same line, and bark up to call the master. They do not let go until the master signals to “stop”.
Creature Feature: Armand Pine or Chinese White Pine (Pinus armandii)
December 21, 2018
This post is from Mrs Linh, who is a Biology teacher at Binh Thuy High School in Vietnam
Pinus armandii is a species of Pine in the Pinaceae family. It was discovered from Xuan Nha Nature Reserve in Vietnam.
Pinus armandii grows on vertical cliffs of 1,000-1,500 meters in height above sea-level. These trees grow to a height of 20-35 meters and a diameter of .4- 1 meter. A cluster of needle have five leaves, which reach a length of about 15-20 centimeters. The pine cones are egg-shaped, that can be solitary or centered with 2-6 cones in the cluster. The cones grow to a length of 8-11 centimeters with a diameter of 5-7 centimeters.
These photos below were taken at Xuan Nha Nature Reserve, Son La province in Vietnam. The reserve is protecting these plants and many other species.

We all enjoy the beautiful sounds of nature. The dawn chorus of birds has been the subject of authors from around the world and throughout history. While the sounds may differ from place to place, they are a welcome greeting to a new day. Our colleague Sujith S., shared some of the beautiful sounds collected outside of his home in Kerala, India, as he began his day. We would welcome similar recordings from our participating students and teachers from around the world. Thanks for sharing a part of your world Sujith!
Bird Feeder: Kerala Style!
December 18, 2018
Our colleague, Sujith S. from Kerala, India intentionally let a papaya in his yard get overripe to see what might come to feed on the fruit. His efforts did not disappoint, as he captured photographs of two beautiful birds at his backyard “bird feeder”! The pictured birds are the Asian Koel and the White-cheeked Barbet. Thanks for sharing these images Sujith!

Some Wildlife of Rwanda
November 7, 2018
Our friend and educator, Robin Shaffer, recently traveled to Rwanda in south central Africa and spent some time in Akegara National Park. He spotted some beautiful birds and got some great looks at Vervet Monkeys! Check out these amazing animals.
November 5, 2018
A student from Ms. Webster’s fifth grade class at St. Eugene School in Milwaukee, Wisconsin made a neat observation of pelicans from a lake near her home. She wrote the accompanying text and shared this photograph. Thanks!
These pelican are found all over the lake that my Island is on. They love smallmouth bass. They fly all over our island. They come on our land. They are white and their beaks are orange. They get their food from the lake. They sometimes hide in the tall weeds.They use their long beaks to catch the fish. Sometimes they don’t catch the fish and fully go under water. It is very funny! You would see them in lakes swimming. They just go down in the water and scoop up a fish.
Bees are Important Pollinators
October 10, 2018
Students from Ms. Webster’s fifth grade class at St. Eugene School in Milwaukee, Wisconsin have been studying the biodiversity around their schoolyard. The student shared this photograph and wrote the accompanying text. Thanks for sharing your observations!
This Bumble-Bee is pollinating some flowers. Bumble-bees are very common in Milwaukee, Wisconsin and all over Wisconsin (Wisconsin is found in the northern part of United States of America or USA). This is due from the variety of wildflowers native to the state. Also, Wisconsin has very nice soil, so lots of different plants can grow there. Bumble-bees pollinate flowers and plants and help our plants grow. They help support the ecosystem, by pollinating our food. Apart from making delicious natural sweeteners called honey, the also help farmers with crops that start out from flowers like potatoes, apples, etc. Bumble-bees are very important in Wisconsin. Bumble-bees may just be annoying but they support life and help us all. They also make HONEY! Yum!
Creature Feature: River Otter
September 25, 2018
Everyone loves otters! Their playful nature and endearing appearance make them a favorite of animal lovers around the world. Otters are fairly global in distribution with different species found on every continent except for Australia and Antarctica.
Here in the U.S. we have two species of otters. The Sea Otter is found in the chilly waters of the Pacific Northwest, where it feeds largely on shellfish and sea urchins. The River Otter is more widely distributed and can be found in freshwater river systems across most of the continent.
Recently, a young River Otter paid a visit to the CHESPAX environmental education center located in southern Maryland, USA. The otter explored the office surroundings for several minutes before returning to the nearby creek. Mr. Wagner from the CHESPAX staff captured some images and a video clip of this aquatic visitor!
Beautiful Biodiversity from Kerala!
September 17, 2018
Our colleague Sujith S. from Kerala, India shared some incredible videos from his home region. Like the current situation in the southeast US, Kerala experienced some dramatic flooding last month. Such events impact not only human activity, but wildlife as well. In the first video, two Indian Cobras took refuge on a ceiling fan of a deserted home during the high water. The second video is of the beautiful Oak Leaf butterfly. The butterfly contrasts camouflage and flamboyance with the flapping of its wings. Thank you Sujith for sharing these awesome videos!
September 7, 2018
Foxes are a species of mammal that are truly global in their distribution. They can be found on every continent, except for Antarctica. Humans have helped in expanding the distribution of foxes, introducing them into new areas for their fur and for sport hunting. Foxes are considered a nuisance in Australia where they were introduced in the 1830s. The red fox is native to the U.S., but there are reports of early settlers bringing the red fox from Europe for release by landowners for hunting with hounds.
Foxes are omnivores, meaning that they will eat both plants and animals. Small mammals such as mice, rabbits, and squirrels are common prey for foxes.
The CHESPAX program has placed trail cameras on middle school properties around southern Maryland. The cameras capture images of wildlife species as they move about the schoolyard. Below are a few images of foxes captured by the cameras.
More European Species
August 31, 2018
Fifth grade teacher Rick Froehbrodt from Franklin STEAM Magnet School in San Diego spent a part of his summer traveling around Spain and Portugal. Rick always has his camera ready to capture some interesting images and shared these photos taken near the end of his journey.
The two jellyfish photographs were taken in Lisbon, Portugal where the Tagus River became a bay and entered the Atlantic Ocean. The Eurasian Magpie was observed in northern Spain. Magpies are relatives of crows and jays and are noisy, but very inquisitive birds. Thanks Rick, for sharing a bit of your adventure with us!
Butterflies from Ukraine
August 15, 2018
Our backyards and schoolyards often host a great diversity of insect species. The Lepidoptera, or butterflies and moths, are among the most beautiful of these species and can be found throughout most of the world. A student of Svitlana L. from the Polatava region of Ukraine shared images of the Southern Festoon buttefly (Zerynthia polyxena) and the Small Magpie moth (Anania hortulata). These butterflies are widespread through much of Europe into Central Asia.
Svitlana teaches English for grades 1-11 in the Poltava region of Ukraine. It’s the largest rural school within the district with approximately 300 students enrolled. The school encompasses 3 groups defined by grade level. Specifically, elementary ( grades 1-4), middle(grades 5-8), and high school( 9-11) . Svitlana involves her students in numerous collaborative projects. Thank you for sharing these images and we look forward to seeing more biodiversity from your region!
Many thanks to Lepidopterist, Eugene Karolinskiy from Ukraine, for his assistance in identifying these insects for us!

One of the iconic wildlife species of India is the Indian Elephant. Wild elephants still roam the grasslands and forests of India. Elephant populations are in decline across Asia due to habitat loss. Elephants sometimes come into conflict with humans as they sometimes will trample crops in agricultural areas. Elephants may consume up to 150 kilograms or 330 pounds of vegetation each day.
During his Teachers for Global Classrooms field experience, teacher Matthew Kuehl accompanied host teacher Sujith S. to the Bandipur Tiger Reserve in Karnataka and captured this awesome video of wild elephants!
Spanish Storks and other sightings
July 27, 2018
Fifth grade teacher Rick Froehbrodt from Franklin STEAM Magnet School in San Diego is spending a part of his summer traveling around Spain. Rick is a keen observer of nature and shared some images and a video clip of of his sightings. Of particular interest are the Black Storks. These large birds have a wingspan of up to five feet across. They often nest around human habitation such as buildings and rooftops. Local people will provide structure and support for the nests of these birds which can weigh up to 1,000 kilograms or over 2,000 pounds! These birds will breed in Europe and spend the winter months in Sub-Saharan Africa. Thanks Rick for sharing your fantastic observations!
Summer Butterflies in Maryland
July 25, 2018
Mr. Harten from CHESPAX was inspired by Sujith’s post on May 27. While school is out in Calvert County, he did a quick survey of butterflies in his backyard. Butterflies are an important element of the ecosystems in which they live. Choosing plants for the garden that are attractive to butterflies are a great way to support local biodiversity.
Schoolyard Biodiversity from Bangladesh

Megafauna from the Western Ghats!
July 10, 2018
Sujith S., a teacher from Calicut in Kerala, India submitted some beautiful photographs of local butterflies from his schoolyard on May 27. Sujith will be hosting educators from the Teachers for Global Classrooms program very soon and was conducting some field visits to prepare for the exchange.
Sujith visited the Mudumalai Tiger Reserve as a potential site to bring the U.S. teachers, a place he sometimes brings his students on field experiences. Despite numerous trips to the reserve, Sujith had never observed a tiger or a leopard, the two top predators at this location. This visit paid off as he observed both species as well as other iconic creatures of the Indian forest, the Chital deer and the Indian Peacock.
Thanks Sujith for sharing your amazing observations!

The Black Widow Spider is one of the two species of spiders that are potentially harmful to humans. The Black Widow is fairly common in Maryland, usually found under cover. These spiders generally avoid contact and will only bite when threatened. These animals feed on small insects which become caught in their sticky webs.
With the warmer days of spring comes a variety of life! This beautiful swamp darner is fairly common in the Eastern United States and Canada, and is the largest dragonfly found in Maryland!
It’s a Worm, It’s a Snake, It’s a Worm Snake!
The smallest snake in Calvert County, Maryland (USA) is the Eastern Worm Snake. This snake is fairly common to our area, often found while digging in a garden. These snakes feed on worms and small insects. These snakes do look like worms, but the scales and pink belly are a good field mark to identify them as a worm snake.
June 6, 2018
This Eastern Tiger Swallowtail was found in Prince Frederick, MD. This beautiful butterfly was posing for its photo op so we could not resist it’s charm!
Right in our backyard
June 5, 2018
This copperhead snake was found cruising through a backyard in Prince Frederick, MD early one night. During the hot, humid months, copperhead snakes are said to be more nocturnal, searching for food when it is dark outside. Copperhead snakes are one of two venomous snakes found in Maryland, and the only one found in Calvert County!
Sounds of the Indian Forest
June 3, 2018
Around the world, springtime forests are filled with the sounds of the species native to that region. In Maharashtra, India the sounds of the Koyal, a type of cuckoo are heard in the video below. Like some other cuckoo species, the Koyal will deposit its eggs in the nests of other birds and allow these hosts to raise their offspring. This behavior is known as brood parasitism. The call of the Koyal is quite beautiful! Thanks to Dr. Sanjyot Chhajed, of Ahmednagar, Maharashtra, India for sharing her video!
Students in Calicut, Kerala, India Survey Schoolyard Butterflies
May 27, 2018
Mr. Sujith S., is a Secondary School English Teacher with a passion for environmental study. Sujith lives about an hour ride from the Western Ghats. This region is one of the eight hot-spots of biological diversity in the world. Butterfly photography is a hobby of Sujith’s and last year, he engaged members of the Eco club from his school in a butterfly survey in and around the campus. They were surprised to see there were about 26 species in the campus itself! See below the beautiful butterflies found during their survey!
Students Help Propagate Endangered Orchid
May 21, 2018
Here is a great example of students taking action for biodiversity. Agricultural high school students from Okinawa Prefectural Comprehensive Center used biotechnology tools to raise the Nagoran, an endangered species of orchid native to Japan. Many thanks to Mr. Jin Yakabi, the Educational Supervisor of the center for sharing this beautiful photo. Mr. Yakabi was a participant in the Japan U.S. Teacher Exchange for Education for Sustainable Development.
Some Southern US Snakes!
May 18, 2018
Rattlesnakes are unique to the Americas. The largest venomous snake in the US is the Eastern Diamondback Rattlesnake. Mr. Harten from CHESPAX spotted this beautiful reptile on a trip to the Everglades.
The Burmese Python is a snake that is native to Southeast Asia that has become established in South Florida. Mr. Harten found one of these big snakes during a Florida camping trip. Our interconnected world sometimes results in non-native species becoming established in ecosystems where they don’t belong.
West Coast Monarchs!
May 15, 2018
During the fall season, millions of Monarchs migrate along the east coast of the United States to their wintering grounds in the mountains of Michoacán in central Mexico.
West of the Rocky Mountains, most of the Monarch population migrates to southern California to spend the winter season. In spring, these Monarchs begin to move north, laying eggs on milkweed plants. The successive generations over the next few months will disperse northward and eastward until late summer. The generation that hatches in August and early September will begin the long distance journey back to sunny, Southern California.
Our friend, Rick Froehbrodt, a fifth grade teacher at Franklin Elementary STEAM Magnet School, located in San Diego, sent these images of Monarch caterpillars feeding on the milkweed on their schoolyard butterfly garden yesterday afternoon. See also below some adult Monarchs feeding on red sunflower. Where will these little insects travel over the next few weeks??
Frog Chorus from Kazakhstan!
May 14, 2018
Our friend Robin Shaffer sent us this great video clip of frog calls from his time spent in the city of Astana in Kazakhstan. The country is located in Central Asia. We are still trying to identify the species calling on the clip. The sound is very similar to our North American Wood Frogs. Perhaps they are a related species!
Frogs from the Land of the Pharoahs!
May 2, 2018
One of the goals of this blog site is to foster discussion between students from around the world about the importance of biodiversity. We have several global partners that are encouraging their students to collect audio, video, and images of their local species to share on this forum.
Our first submission comes from Mr. Youssef Mourard Reyard, a teacher at the Narmer American College in Egypt (Middle and High School). Mr. Youssef collected this sound file of an Egyptian frog species near the Narmer campus.
