Welcome back to the US Fish and Wildlife Services Conservation
My name is Chelsea McKinney, your host,
as we explore various conservation
careers, new species, and different types of technology
that conservation professionals use to observe wildlife.
Today we're coming to you from rural Maryland,
in a bog area where we're hoping to find some secretive bog
turtles I'm here with Christine Peterson from the University
of Vermont, who's studying the bog turtles' habitat.
Christine, thank you so much for being with us today.
Can you tell us, what do we need to know about this bog turtle?
So bog turtles are pretty small.
They're only about four or five inches long.
And they really like this kind of open, boggy habitat
that we're in here that has a lot of sunlight, not too
They like to hang out and bask in the sun.
But there's a good mix of mud and dry ground,
because they are semiaquatic.
So sometimes, they like to be in the water,
and sometimes, they'll be on land.
So for part of the year, during the summer
from April to October, they'll be out.
And this is during their nesting period,
and this is when they'll lay eggs.
But then for the rest of the year,
during the winter when it's really cold,
they'll actually hibernate underneath the mud
when the top freezes over.
So they're only active for part of the year.
But some of the most important parts of the habitat
here are the vegetation that they really like,
and the open canopy.
Now, the bog turtle is a threatened species.
Why is it a threatened species?
So there's three main things that are really
a threat to bog turtles.
One of the biggest ones is development.
So lots of people like to build houses and buildings
in these kind of beautiful landscapes,
but unfortunately that can I have negative effects
on this kind of wetland.
Obviously, the bog turtles are really cute and very
charismatic, and people want to take them home with them
and make them pets, but this is where they're supposed to be.
This is where they belong, and so
taking them home is a real threat to their population.
Absolutely, and they deserve to be in their natural habitat.
Now, I know bog turtles are rare in this type of ecosystem.
What kind of technology are you using to find them?
Well, one way that we can help find them multiple times
is using a GPS like this, where when we do find them
in the field from doing surveys and walking around and looking
for them, we can record on here exactly where we found them.
And recording those kinds of points throughout this habitat,
we can figure out where they most like
to hang out so that we can more likely find them next time.
And another really interesting way
that we can help figure out where these turtles are
is by attaching a little radio transmitter backpack onto them.
And then we can track them when we're out in the field.
And Nathan Byers, a graduate student
at Towson, who is also looking at bog
turtles for his research, and he's been attaching these radio
So let's see if we can go find him and find some turtles.
Yeah, let's meet Nathan.
Nice to meet you, Nathan.
Nice to meet you, too, Chelsea.
Christine said you are the bog turtle guy,
and I see you've got some equipment here.
Can you tell us how we're going to find these bog turtles?
So at this wetland, I have little bog turtles
that have little radio receiver backpacks on them that send out
a constant little radio signal.
This gizmo right here pretty much
picks up on that constant little ping that it's sending out,
and this is antenna makes it a little louder,
so that I can find it.
So you can hear in that direction.
We have a really strong, loud signal.
In that direction, not quite as loud.
And that's exactly how that works.
So using this, I track right to the turtles.
Let's find some bog turtles.
Let's find some bog turtles.
Definitely hearing a stronger sound in that direction.
Yeah, she's somewhere right in here.
Now it's just a matter of actually finding her.
I think she's right here.
So what I'm going to do now is take off the antenna,
so I can try to find her a bit closer.
Oh, so that will--
Oh, I see her.
There she is.
There's by bog turtle.
And this is the little backpack you were talking about.
That's the little backpack.
That sends out a constant little sound for me to pick up.
That is incredible.
She's just ate.
So how do you know that?
So you can see on her mouth, she's
got something hanging down there.
So it looks like she probably ate a slug or something
like that, which is one of their favorite animals to eat.
And why are bog turtles so critical and important
to the ecosystem?
So bog turtles serve as a really effective sort
of wetland indicator.
Because they require these sorts of wetlands
that are relatively low, have a lot
of low vegetation, like we see here.
And they use that vegetation for every aspect of their life,
from nesting, to basking, or hanging out in the sun
to raise their body temperature, and pretty much every aspect.
So if there any problems with the vegetative community
in bogs like this, the bog turtles
are the first to pick up on that.
And if we see them leaving the bogs,
then we know something's wrong.
So you definitely don't want to pollute wetlands like this.
You see a wetland like this, just
leave it alone, because these are very sensitive.
And often just people walking through them can cause issues.
Other than that, just things closer to home.
Just try to eliminate runoff from your lawn, things
like insecticides, pesticides, other things like that,
because those go straight into our watersheds
and straight into our bogs.
The technology that we can use to study wildlife
has become absolutely extraordinary.
Thank you so much, Christina and Nathan, for being with us
We're looking forward to you guys recovering and delisting
the bog turtle soon.
We'll see you guys next time, on the US Fish and Wildlife
Services Conservation Connect.
