Reptiles and Amphibians

We have been assessing reptile and amphibian populations within the Tollway corridor using:

– baited hoop traps
visual encounter surveys
minnow traps

Radio tracking turtles in marsh below bridge construction

Blandings Turtle
Assessing Impacts of the Carp Barrier on Movement of Reptiles and Amphibians
I-294
– IL53-IL120 extension assessment
IL Rt 390 extension
North Chicago Wetland Mitigation Site
– Turtle health

Highlights from our work:

  • Head-starting and releasing turtles is costly and will not mitigate population declines on their own in the I-355 corridor, as adult mortality is too high. Less costly alternatives include protecting nests, controlling predators, and releasing hatchlings.
