I felt along its back to where I thought the shell should end, but my hand just kept going.”

Since she had no tracking device, she was not one of the turtles that had been released into the area. DNA tests showed that she belonged at the site and was not a lone traveler from a southern state. Southern Illinois is at the northern end of the turtle species’ range.

Populations of this state-endangered species have declined because of habitat changes including dams, drained swamps and river dredging. Only Union and Jackson counties offer the habitat that the turtles need to reproduce and thrive. Locating any wild turtles in these counties will help determine the next steps — whether to preserve a population or reintroduce more alligator snapping turtles in Illinois.
“Bolstering a hidden population of an endangered species is better than starting a new population in the area,” said Ethan Kessler, a graduate student of natural resources and environmental sciences at the University of Illinois and a co-author of the study. “However, since no wild alligator snapping turtles have been found in Illinois since 1984, reintroduction efforts make sense.”
For several years, researchers have purchased turtles reared in a facility and released them at ages 2, 3, 4, 5 or 6. They also released about 90 adult turtles. Most of the animals go into creeks with radio transmitters attached to their backs so they can be relocated and tracked.
Researchers were conducting their biannual catch-and-release program when they found the wild turtle, close to the same spot and 30 years, almost to the day, after their last wild alligator snapping turtle was found.
“Finding this individual does not indicate that there is a functional, stable population of wild alligator snapping turtles in Southern Illinois,” Kessler said. “When a population dies out, a single turtle may wander around like a zombie waiting for the end of its days.”
“She is marked, so in case of an incidental encounter, we will know it’s her,” he said.
One of the challenges of tracking turtles that have been introduced in Illinois is that they disappear underwater and may not be seen again until divers retrieve them.
“If we succeed with our project in introducing a new, viable population of alligator snapping turtles, it’s likely that no one will see them,” Phillips said. “It’s not as if we’re studying bald eagles that soar above us. I may never know the fate of these turtles, but it’s cool to know that this wild space exists in Illinois.”
The alligator snapping turtle is listed as threatened in the U.S.
