One Student's Experience with the
MARA Project!
Gabriella F. from Ms. Coggeshall's class at Calvert Middle School made some interesting observations from her home (Prince Frederick SW). She shares some of her observations below:
I was
doing my homework when my dad called me outside from the garage. He told me to
come quiet and slow, and naturally, my first though was “my puppy got his head stuck in the porch railings again!” So I
walked out and up to my dad. “What is-”
I started to ask, but he cut me off, put his finger to his face and pointed to
what I thought was a rock on the side of our front porch. “You really brought
me out here to show me a rock?” I asked quizzically. “But” I thought, “at least
I don’t have to get my puppy’s head out of the railings!” “NO!” He said
defiantly. “Go look.” I walked over and saw this little guy! This is a Cope’s
Gray Treefrog. Cope’s Gray Treefrogs have a high trilled call and toepads that act
as suction cups and allow them to climb and grip objects. This is a great
adaption due to the fact that they like to hang around in trees. As you can
see, this little guy was using the toepads to its advantage. That advantage was
getting away from the camera!
This is another Cope’s Gray
Treefrog that was found in my pool filter. After taking him out of the water
and making sure he was alright, we placed him back where he belongs!
This is a Black Rat Snake. They
are not poisonous to humans, but if provoked, man do they bite! We found him
under our porch, but where afraid my puppy would eat him, so we put him in this
bucket so we could put him back into the woods.
This is an Eastern Fence Lizard. My younger
brother found this little guy and put him in an open container so that he could
look at him for a few minutes, and, don’t worry! We put him back.
When I
went to listen for frog calls on last Tuesday or 5/22/12, I heard the low ‘rum’
sounds of some bullfrogs and my little Cope’s Gray Treefrogs buddies were
trilling out too!
All right! So here are some questions!
Why are amphibians &
reptiles so important?
One
of the biggest jobs of amphibians and reptiles is acting as one of the first indicators
to bad air, and bad water. Frogs live in water and we drink water. So when
there seems to be a problem with the water, which we can see because of frogs
dying off due to water cleanliness and salinity, it shows that the water is not
safe for us to drink. Also frogs, as tadpoles, eat algae, which clear the water
and allow the sunlight to filter through the water and then the underwater
plants are able to get sun. This last job isn’t as important to the environment
as it is to us. Frogs eat insects such as mosquitoes and flies. This leads to a
nice even amount of pesky insects and leaves the summer days less ‘buggy’.
Why are amphibians disappearing?
Well, with this, the reasons make us look like
pretty bad predators. We are destroying their habitats by bulldozing ‘their’
land to build homes and other establishments. Not only does bulldozing take
away their land, but it also is another cause off run off and pollution in the
water. Non-native species can also be a big problem. They take the native species
land, food, and other needed resources. People hunt and kill frogs, not as much
here as other countries though. Illnesses are one other huge impact. Chytrid is one of the worst amphibian skin infections, it kills
many and fast.
What actions can we do to help
these species?
We can participate in programs such as MARA to
locate frog species, where they live, and try to protect them from harm. When frog species, especially endangered
ones, are located and found in their most desirable place to live, we are able
to protect the area from harms such bulldozing, water pollution, and from
hunters. We can also use less air harmful pesticides and outdoor sprays. They
pollute the air that both we and the frogs breathe. But frogs can’t take all of
that harmful air and they get sick and die. One other thing is to not release
exotic amphibian pets into the wild.
This causes problems with non-native species, especially invasive ones.
Non-native species will come and possibly overtake the native populations. This
will lead to less space, food, and water for the native species and more
competition between the native and non-native populations.
