Broadhead Skink (Eumeces laticeps) is one of many herp species found in or near the Shawnee National Forest.

LaRue Road and Forest Service Road No. 345 also known as "Snake Road" will be closed to vehicle traffic for about two months to allow these herps, some that are listed as threatened and endangered in the state and the country, to safely cross the road.

The road will remain open to people on foot, so if you are near the area, it would be an opportune time to see a lot of reptiles and amphibians in a single location, and especially on the two mile road.

The state is home to 35 snake species, including water moccasins, southern copperhead, blue racer, northern scarlet snake, northern and prairie ring necked snake, and southern black racers, just to name a few. 

The road closure also is ideal for those who love to watch birds, see native plants and observe insects as well. For more information on Snake Road and the migration, visit the Shawnee National Park website.
