text: Yes, they are, depending on the species. The ones I noticed were the Bird-voiced Tree Frog, Illinois Chorus Frog, Blanding's Turtle, Timber Rattlesnake, Illinois Mud Turtle, Kirtlan's Snake, Jefferson Salamander, Western Hognose Snake, Dusky Salamander, Four-toed Salamander, Silvery Salamander, and the Great Plains Rat Snake. I'm familiar with some of these species because they are found in some caves in Illinois. \n\nIllinois does have an endangered species act. There is a 57 page document listing the endangered species by county,  that can be downloaded at:\nhttp://dnr.state.il.us/espb/\nThe direct link is:\nhttp://dnr.state.il.us/ORC/list_tande_bycounty.pdf
