(The Center Square) – One hundred years
ago, ornate box turtles were found in half of the 102 counties in
Illinois. Now they live in only 10 counties.
Dr. Matt Allender, a scientist at the University of Illinois and
clinical veterinarian with the Chicago Zoological Society, uses a team
of Boykin spaniel dogs to hunt for endangered ornate box turtles.
The dogs are much more efficient at collecting the four-inch
brown-and-gold-patterned box turtles than the scientists on Allender’s
team.
“People can find a box turtle, about one in every 2.5 search hours. So
if you are out for a day, you can find about four. One of these dogs can
find a box turtle every 15 minutes,” Allender told Illinois Radio
Network.

The dogs don’t hurt the box turtles. The scientists study the creatures
for about an hour and then they put them right back on the prairie. The
effort is part of the longest and largest health survey of box turtles
in North American, Sondra Katzen of the Chicago Zoological Society told
Illinois Radio Network.
Allender says the ornate box turtles are sentinels of environmental
health.
“Even if you don’t care about wildlife and you don’t care about turtles,
these animals are critical for evaluating the natural resources that we
provide our society on. I’m doing this to save the world and we’re using
box turtles to do it,” Allender said.

Ornate box turtles do not need a lot of space, but
they cannot thrive on just any tract of prairie, Allender says. They
need prairie with diverse nutrients and soil composition.
At the Nachusa Grasslands, a 4,000-acre reclaimed prairie, there are
over 70 different species of prairie grass or prairie plants that
generate seeds and host insects that turtles and many different
species of birds and pollinators depend on. At Nachusa, the ornate
box turtles have an important animal partner in the native bison who
live there. As the large, heavy bison tramp across the grasslands,
their hooves churn the soil, spreading seeds and creating habitat
for the bugs and insects that the turtles eat.
When the prairies and the bison disappeared, ornate box turtle
populations in Illinois were decimated as well, Allender said.
