Known to some as the smiling turtle, the
Blanding's turtle actually has something to smile about because of the success
of a seven-year effort by the Lake County Forest Preserves to support the
reptile, which was declared endangered by the state in 2009.
"I'm really excited about the point we
are at," said Gary Glowacki, wildlife biologist for the Lake County Forest
Preserves.
Local preservationists are very close to
having a viable population that can reproduce on its own along the northern
Lake Michigan shoreline area in Lake County on the border with Wisconsin, where
thousands of acres between state and county preserves afford the turtle a place
to thrive and room to roam.
"The bigger the area, the better,"
Glowacki said, since the turtle prefers to reside in mats of cattails and
wetland until it is ready travel to a dry upland area to dig a hole and lay its
eggs. Sometimes, the turtles cross the road to find a good nesting site, and
roadkill takes its toll on turtles in general.
Illinois has 17 species of turtles, according
to the Illinois Department of Natural Resources (IDNR). The Blanding turtle's
range includes Canada south to into New England and west through the Great
Lakes to Nebraska, Iowa and extreme northeastern Missouri, according to the
forest preserve.
Before the area became farmland, the
Blanding's turtle — named for American naturalist Dr. William Blanding — was
probably common in the county, but the Chiwaukee Illinois Beach Lake Plain
between Waukegan and southeast Wisconsin is the only area expansive enough for
a large population to become viable.
Along with the IDNR, Lake County officials
have been teaming with the McHenry County Conservation District, the Wisconsin
Department of Natural Resources, The Nature Conservancy and the Illinois Nature
Preserve Commission on the turtle project.
"We've been working on it for seven
years, and survival rates are increasing. The next step is some of the turtles
we put out will hit the reproductive stage," said Glowacki after recently
picking up a batch of small turtles from McHenry, where they were incubated.
"We bring them back and put them in tubs
and grow them so they have a better chance of surviving," he said.
Predators like raccoons are trapped to reduce predation, though crows,
chipmunks, foxes and skunks are also a threat.
The young turtles come in about the size of a
quarter and leave when they're more the size of a cookie, three to six inches
across. The restoration program has been supplementing the local population
with about 100 turtles a year, although last year the number hit 178.
"We over-shot it a little bit,"
Glowacki said with a laugh.

one of 112 baby turtles that will be released next year. (Lake County Forest

The turtles are fed a kind of turtle Jell-O
that has all the required nutrients. Later, they get time outdoors in pens
where they will eat their natural prey, such as earthworms, small fish and
crayfish, before being released to fend for themselves. They can live up to 80
years, and an adult sized turtle is the size of a helmet.
"Anything they can get their mouth on,
they'll eat," Glowacki said. When staffers live-trap the turtles to count
them and take blood and saliva or attach a transmitter, they put a sardine in
the trap.
"They go after that," Glowacki
said, "but when a crayfish is in the trap, attracted to the bait, a turtle
will soon follow."
This year, the program received help from two
interns from The Wildlife Epidemiology Lab within the College of Veterinary
Medicine at the University of Illinois. Their blog about taking blood samples
and saliva swabs, among other things, is at http://vetmed.illinois.edu/wel/author/laurenjohn/.
Glowacki said their quest for a viable
population is closer than ever.
"Modeling supports that were not quite
viable, but very very close," he said, noting the program has the largest
population of Blanding's in the state. "It's not quite viable, but we are
definitely headed in the right direction.”
The program is funded through the
Preservation
Foundation of the Lake County Forest
Preserve, which has an Adopt a Turtle program where donors can name a turtle
and get a behind-the-scenes tour for a $120 donation. Last year, the program
exceeded its $12,000 goal. This year, the amount was about half that in
mid-October, but officials said there was a big push in 2016.
Richard (Dick) Reilly, 70, who moved to Volo
recently from Wauconda, has been a turtle champion to three specimens so far —
Slick, Turbo and Bucky, as in the University of Wisconsin's Bucky Badger
mascot. He first saw something about the program in the preserve's newsletter.
"It just clicked right away for
me," he said. "We grew up being instilled as nature lovers by my
parents. (We) had a lot of turtles and frogs around outside, and we learned to
like them at a very early age.”
Reilly added that participating in the
conservation effort "was a way to try and help turn things around. I'm all
in."
Information on the Adopt-A-Turtle program can
be found at the district's headquarters in Libertyville and online at https://www.lcfpd.org/preservation-foundation/adopt-a-turtle/. Donations
are being taken to be a turtle champion and be part of the tour in November.
"There's still a month left,"
Glowaski said in mid-October. "Hopefully, we can make (the fund-raising
goal) in the end."
