Sharing the
Bay celebrity of crabs, oysters and Bay grasses is the diamondback
terrapin, the newest poster child for Bay restoration.
We’ve
all seen a blue crab, and an oyster — though scarce — is no mystery.
But terrapins have kept a low profile, hiding out in marshy areas
and quietly surviving in Bay shallows and tributaries.
Now
these secretive reptiles are basking in the spotlight of
environmental restoration projects, and with the help of local
conservationists, terrapins have risen to notoriety as an
up-and-coming Bay spokes-species.
Out of the Marsh and into the
Soup
Malaclemys
terrapin, or diamondbacks, have for eons resided in brackish marshes
and tidal creeks from Cape Cod down the East Coast, around the
Florida Keys and across the Gulf Coast to western Texas. As the only
turtle in the world to inhabit solely brackish waters, diamondbacks
are perfectly at home in the shallows of the Chesapeake Bay estuary
and its tidal waters.
They hibernate in the mud during
winter and emerge in late May to mate and lay eggs on sandy summer
shores.
Unlike sea turtles, who maneuver through deeper
waters with fins, terrapins prefer the shallow inlets along the
coast and use their webbed feet to both swim and climb on logs for
basking. These water-loving creatures leave their element only for
soaking in the sun or for nesting. They build nests to hold their
pinkish-white eggs above the high tideline on sandy shorelines. Both
nests and hatchlings are vulnerable on the beach.
There,
terrapins are prey — especially in their juvenile stage — to crabs,
crows, gulls, rats, muskrats, foxes, raccoons and skunks. Terrapins
are also predator, for these carnivores feed on aquatic snails,
crabs, insects, fish and small bivalves
To help them tear
their fishy meals, the turtles have beak-like mouths and long claws.
Between claws and shell, their speckled salt-and-pepper skin bears
marks as unique to each turtle as a fingerprint to a human.
Tan-brown to gray-black shells bearing their namesake diamond
pattern on plates called scutes grow in concentric rings, forming a
tough exterior.
Their toughness makes mature terrapins a dish
you’d have to work at getting. So terrapins’ most troublesome
predator is humans.
Terrapin soup isn’t as popular as it used
to be, but terrapins have long been trapped by watermen and sold for
food. To catch a terrapin you need a permit, and you can trap them
legally only August through April, when there is no upper limit on
how many terrapins you can take. However, a caught terrapin’s
underside shell, or plastron, must be at least six inches long. If
you’ve got a keeper, it’s likely a mature female, since the males
are generally smaller. Watermen hoist the turtles aboard from
fishing nets.
Even today, terrapin supporters worry that
taking too many females could create problems for turtle
populations.
Bob Evans, a longtime Southern Anne Arundel
waterman who was involved with the state terrapin program and who
now lobbies for the Maryland Watermen’s Association, used to catch
terrapins to sell. He has since focused on fish and crabs. “People
don’t catch many terrapins commercially anymore,” he
says.
Accidental catches are down, too,
since the 1999 law that required turtle excluder devices for crab
pots to help prevent accidental turtle fatalities. Turtles can only
survive a few hours completely underwater, so keeping them out of
crab pots helps terrapins and makes more room for crabs. Evans
helped design the Bay version of the excluders, known as TEDs, which
are used worldwide to prevent accidental catches of turtles of all
sorts.
These turtle excluders are a thick wire bent into a
rectangle strip and secured with hog rings at the narrow end of the
crab pot’s funnel. Only four inches long and an inch and a half
high, this metal rectangle is too small for the convex-shell of
turtles. But thinner crabs easily can scuttle through.
“We
used to find them in our crab pots, and then we’d release them,”
said Kenneth Keen, a former waterman now at DNR. “Once they started
putting in TEDs, that helped a lot.”
Terrapin eggs are also
protected by law from harvesting or tampering.
Nowadays when
terrapins appear on the market, turtle supporters often buy them to
return them to the wild. An adult terrapin usually sells for about
$6, says Marguerite Whilden, co-founder of The Terrapin Institute,
who reports that she bought the same terrapin three times. “I could
tell by the small notch left on the turtle where our tag had fallen
out,” she said.
The Terrapin Institute wants the turtles to
be common Bay citizens once again. But right now, neither they nor
anybody else knows just how many terrapins are out there.
“We don’t have a lot of good, quantified data,” said
fisheries biologist Martin Gary at the Department of Natural
Resources. Lacking a terrapin management program, the best sources
of information DNR has are nesting data it’s collected, University
of Maryland studies and estimates made along the Patuxent River in
documenting the Chalk Point oil spill of 2001.
Anecdotal
evidence points to terrapin survival as well. “Field biologists give
feedback throughout the Bay that indicates that terrapins are fairly
routinely encountered,” says Gary.
Hoping to find answers to
many terrapin questions, researchers have begun tagging female
terrapins with small metal bands bearing an identification number in
order to get an idea of how many terrapins are out there and where
these terrapins go.
Restoration’s New Poster
Critter
Terrapins
have found their place in the spotlight as the ideal symbol of the
Chesapeake — a segue between water and land, since they live mostly
in the water but breathe air and come ashore for basking and
nesting.
University of Maryland’s athletic teams took the
terrapin as their mascot in 1933, and Testudo has since become
famous. In 2002, when the University of Maryland’s men’s basketball
Terps won the NCAA championship, the school’s athletic department
donated part of the proceeds of their Fear the Turtle merchandise to
diamondback research and conservation.
Terrapins have found
sanctuary under the law as well as fame in sport. In 1994,
diamondback terrapins were named Maryland’s state reptile. In April
2001, former Gov. Parris Glendening sparked the Terrapin Task Force,
bringing a diverse group of people together to evaluate how
terrapins were doing in the Bay. The Task Force later urged that
terrapins were “a historically notable species in decline and in
need of increased state protections.”
Public awareness of terrapins is widely credited to
Whilden’s terrapin outreach program at DNR from 1998 to 2003.
“The terrapin program has greatly increased awareness of
terrapins and of environmental awareness,” said Willem Roosenburg,
an Ohio University biologist who studies terrapins on the Patuxent
River.
Whilden’s terrapin program not only taught students
and adults about terrapins but also used terrapins to give a
friendly face to conservation and to involve people in
stewardship.
But under a new governor the program fell to
budget cuts, and the task force ended with the program.
“When
we were eliminated from DNR, the problem wasn’t eliminated,” says
Whilden, who shifted her terrapin efforts to the private sector with
The Terrapin Institute.
Regardless of their sponsor,
terrapins work magic when people see them.
“They’re
engaging,” says Whilden of these charismatic creatures. “They’re
something the public can handle and relate to.”
Terrapins
bring shells-full of stories to their spotlight.
The annual
hatching of Terrapins coincides with the blooming of Maryland’s
native plant, turtlehead, in August.
Terrapins’ history with
humans dates back to early Native Americans, who ate their flesh and
crafted the shells into tools, weapons, jewelry and more. The very
word terrapin is derived from a Native American language. Colonists
used terrapins to feed pigs and indentured servants. Terrapins
eventually ended up in gourmet bowls of terrapin
stew.
Terrapins are no longer common fare for restaurants.
But until five years ago, the historic Baltimore restaurant
Haussner’s, which has since closed, served terrapin. Culinary
adventurers can find recipes in Maryland cookbooks and on the
Internet, where you can even find a recipe for low-carb terrapin
soup.
Terrapins make storytellers as well as stew. The 13
scutes, or diamond-shaped plates, on the terrapins’ shells make
convenient references to history: America’s 13 original states; a
Native American tale cites 13 moons on a turtle’s back; 13 years of
prohibition (during which terrapin populations strengthened,
attributed to the lack of sherry wine for terrapin soup); the 13th
amendment abolishing slavery (which ties to the turtle’s days as
food for indentured servants).
Another terrapin tale is the
terrapin’s success. At a time when oysters battle diseases and
overharvesting, Bay grasses can’t seem to plant roots and Bernie
Fowler still can’t see his sneakers, the terrapin is one of the few
hearty survivors in the Chesapeake. There are no real disease
issues, and their population has rebounded after nearly being wiped
out from overharvesting in the early 1900s.
With so much
negative news about the Bay in the last decade, the terrapin gives
the public a reason for hope — which the terrapins unknowingly
symbolize by returning to the beach to nest.
Terrapin Trouble
But not all
the stories are good ones. Anecdotal research — stories people tell
rather than scientific data — shows the decline of the Bay’s
terrapins over the last 50 years.
Decreases in the Bay’s
abundance have been noticed by watermen and citizens
alike.
“As far as I’m concerned, there’s not as many
terrapins as there used to be,” says Evans. “Back in the early 1970s
on the Patuxent, when we’d haul in the seine net looking for fish,
we caught them by the thousands.”
Whilden, too, tells stories of times “when terrapins were
commonplace.” As a child, she remembers seeing the heads of swimming
terrapins in Whitehall Bay.
Roosenburg says that on the
Patuxent River, where he conducts most of his terrapin research,
“populations are less than 50 percent of what they were four years
ago.”
But it’s all comparative, say some.
DNR’s
fisheries biologist Gary reports that terrapins appear to be doing
well considering the habitat loss and water quality problems of the
Bay, especially when compared to other animals that haven’t fared
well, such as shad. Even though there was a fishing moratorium on
shad in 1980, it didn’t help the population rebound like the success
of the rockfish.
“The outlook for terrapins is brighter now
than it has been for a while,” says Gary, “They’re more common than
people think.”
Like shad, rockfish, crabs, oysters and all
the other Bay creatures, terrapins are threatened by pollution,
habitat loss and overharvesting.
What’s the number-one threat
to the tough-shelled terrapin?
“Over-fishing is a good
possibility,” said Mary Hollinger, an aquatic biologist and
oceanographer at NOAA as well as a partner in The Terrapin
Institute. Because harvesters only take the reproductive females,
every time a female is caught, that means thousands fewer eggs will
be laid.
Evans has another idea. “Because boat traffic is so
severe, the main problem is boat injuries,” the waterman says.
Turtles lucky enough to survive contact with a boat propeller may
still suffer disease-prone gashes in their shells.
Other
problems are the proliferation of water-clouding jet skis, abandoned
underwater crab pots and fyke nets — tubelike nets staked in the
shallows to catch terrapins but also used for finfish.
But
habitat loss likely outweighs all these other factors.
The
toughest problem is “having appropriate habitat where they can lay
their eggs,” according to DNR’s Gary.
Returning shorelines
to habitats that welcome terrapins is on the minds of both DNR and
communities.
“We need to make changes in habitat and water
quality,” says Stephen Barry, coordinator of Arlington Echo Outdoor
Education Center, where a restored natural shoreline has made a good
home to terrapins released there in June.
Easing Terrapin Troubles
“We don’t
have a dedicated program for terrapin preservation right now,” said
DNR’s Gary, who says that the department continues to try to
coordinate with Whilden to address crab pot issues and include
terrapins in fisheries discussions.
Terrapin preservation
may be a by-product of other preservation and conservation efforts,
but improving underwater grasses proliferation and oyster
restoration are both tied into water quality and habitat that
benefits terrapins, says Gary. Terrapins will benefit from
ecosystem-based management, which Gary says, is “very much the focus
of where fisheries management is going.”
Still, terrapin
lovers call for a more drastic step.
“This is not brain
surgery,” says Whilden. “Let’s not wait until the next crisis before
we look at management.”
NOAA biologist Hollinger agrees. “We
need to get a handle on the situation,” she says. “We need a
moratorium until we really get a feel for what’s going on.”
An ideal step right now? “A moratorium on terrapin
harvesting, with compensation to the fishermen at twice what they
would have made on the turtles’ sale,” says Whilden. “And we need to
compensate the buyer, too.”
Researchers credit watermen with
providing much of the needed data on harvested terrapin numbers. But
they worry that what we think we know is nowhere near
accurate.
“We know there’s been over 1,500 turtles captured
this year, with only 600 reported as being caught for sale. A pet
trader told us he bought at least 500,” said Hollinger. “And these
are just the ones we know about. Who knows how many others were
captured and not reported?”
A Little Help from Their
Friends
With their
curious eyes, cute faces and easy-to-hold shells, terrapins may be
the new face of Bay restoration. It sometimes may be hard to get
students to care about a plant or a shellfish that looks like a
rock, but there’s something special about a turtle.
That’s
why The Terrapin Institute and other groups are turning terrapins
into teachers. Terrapins raised in the classroom can provide many
lessons about wildlife, history, society and environment, as well as
about health and even art. Terrapins have even been brought into
classrooms with autistic or disabled children for supervised visits,
because often, these children respond well to
animals.
Permits allowed the Terrapin Institute 100 eggs for
research. They collected the pastel eggs about the size of grapes
from Chesapeake Bay Environmental Center, formerly Horsehead
Wetlands Center, and various citizen-reported locations.
The
eggs, carefully positioned in Pearlite to hold moisture, are kept
under close observation at Arlington Echo. There too, hatchlings
salvaged from a Holiday Inn parking lot in Grasonville are growing
strong in large outdoor tanks protected from predators by wire mesh
and observed and fed daily. Next, they’ll move into Arlington Echo’s
Resource Lab or head off to Head Start programs to be raised until
they’re ready for release. The terrapins are generally low care,
have plenty to teach and will grow before students’ eyes in the
classroom.
Lots of students and their parents are getting to
know baby terrapins nowadays. This spring, home-schoolers released
terrapins that they had raised and cared for at Carrie Weedon
Science Center in Galesville. Students named the terrapins, the size
of a quarter when they arrived at the Center, Hope, Freedom and
Braveheart, in honor of their birthday, September 11, 2003. The
three were released into their new home at Chesapeake Bay
Environmental Center in Grasonville.
“I think the kids became
aware that there are terrapins in the Bay,” said Sharon Solberg,
teacher at the Science Center, and that they’re “more than just a
mascot for the university.”
School groups and recently Planet
Earth Campers at Arlington Echo have also set terrapins free onto
the natural shoreline.
Not just kids are into terrapins. At
Franklin Manor, in Churchton, six tagged female diamondback
terrapins were released by the boat ramp on Deep Cove Creek.
Community member Pat Keeler helped coordinate the release at the
community’s shoreline.
“After Isabel’s destruction, it felt good to be a part of
something constructive,” Keeler told Bay Weekly. As far as she knew,
none of the tagged terrapins had reappeared, but Keeler’s community
looks forward to being a part of the program again.
Three
couples from D.C., enamored with Whilden’s terrapins, asked to raise
the hatchlings. Raising terrapins, or protecting hatchlings until
they’re less likely to be targeted by birds and mammals, are other
ways individuals can help restoration efforts from their homes.
Even businesses want their terrapins — and not for soup. At
Herrington Harbour Marina Resort in Rose Haven, terrapins are
fostered and lovingly visited by customers and then let go when they
grow bigger. Staff and volunteers just released 11 of the turtles in
June, and if they acquire more hatchlings, they plan to raise them
as well.
Cantler’s Riverside Inn in Annapolis keeps
terrapins, as well as horseshoe crabs, in tanks where customers can
observe a live terrapin up close while they wait for their food.
They have about 10 terrapins that they’ve either caught or received
from customers who know of the terrapin tanks. Instead of serving
them, this restaurant releases them as they mature.
“Putting
something back into the ecosystem is huge from a conservation
standpoint,” said Whilden.
More than 1,000 such terrapins
have been tagged and released into the Bay since March, according to
Hollinger. Many of the terrapins don’t survive in the wild, but many
do. Those hearty turtles often can be sighted close to where they
were released
According to Whilden, it’s not enough to simply
tell students that the Bay is in trouble. Truly educating the public
means teaching kids what citizens can do to help — whether it’s
writing to their representatives, running for office, organizing
themselves to collectively speak out on environmental concerns or
physically putting something, like terrapins, back into the Bay —
instead of stewing in frustration.
“Kids care when something
engages them. There has to be emotion to learning,” said Barry,
whose center is raising about 65 of the hatchlings and more than 100
eggs to be raised later in classrooms.
Such restoration
projects like releasing terrapins and building habitats help kids to
learn how to give back to the Bay.
Turtles are the tool,
says Whilden. “Our product is stewardship.”
Perhaps like its
cousin the tortoise, the terrapin reminds us that slow and steady
wins the race.
Turned Around by a Turtle
“We are
running out of time,” Whilden said, slapping her palm for emphasis.
Campaigns like hers seize the time, not waiting for years of
studies, years that could hurt a population in the meantime.
Science data can tell us where the problems lie, but, says
Whilden, “The real trick is how to get society to start doing
something about it.”
As we wait, focusing on a small part of
the ecosystem, the diamondback terrapin seems to work at bringing
attention to the larger issues at stake — taking care of the entire
Bay in all its economic, social and environmental realms.
Homing in on one small aspect of the Bay makes conservation
more manageable — instead of trying to take on the whole Bay at
once. “Instead, we have one product,” says Whilden. “We don’t want
to become General Foods.”
In focusing so intensely on
terrapins, researchers hope to find ways for everyone to make
behavioral changes that will lead to a cleaner and healthier
Chesapeake Bay.
“If you ask people if they care about the environment, a
great majority will say yes,” said Barry. But Barry would add that
the majority of people have no idea how to help the environment, or
even understand how their own actions impact the Bay.
A
growing number of area residents, however, are becoming concerned
about the terrapin.
“Just yesterday someone called in that
had a terrapin nesting in their back yard,” said Gary. “I could tell
that he was really concerned. Fifteen years ago he wouldn’t have
cared.”
Terrapins even got the attention of Comptroller
William Donald Schaefer. Speaking at the Board of Public Works
meeting in April, Schaefer chastised the Department of Natural
Resources for not supporting The Terrapin Institute’s turtle
conservation and research. “You ought to try and get somebody
interested in preserving those terrapins,” he said last
August.
Now in the glow of public attention, the terrapins
continue to prefer to hide out in creeks and shorelines. They’re
relatively shy creatures for such intense
limelight.
