Shawnee Forest to the Mississippi: Three Species, Real Risk
Illinois is a state of stark contrast — the flat cornfields of central Illinois are virtually snake-free, while the rugged sandstone bluffs of the Shawnee National Forest in the south host the state\'s entire venomous snake population. The Illinois Department of Natural Resources reports approximately 40 venomous snake bites annually, almost exclusively in the southern 20 counties.
Hikers on the River-to-River Trail, rock climbers at Garden of the Gods, anglers along the Mississippi River, and homeowners in the unglaciated hills of Jackson and Union counties all face real exposure. The Eastern Massasauga, a federally threatened species, persists in northern wetland remnants but poses minimal human risk.
