On Saturday September 26th join the St. Louis Herpetological for its annual field trip down to Snake Road at LaRue-Pine Hills Natural Area in Illinois' Shawnee National Forest. As many of you know this 2.5 mile road that bisects the swamp from the bluffs is closed each fall and spring so snakes and other swamp critters can cross over safely to get to the bluffs for hibernation or to the water for food and breeding. For many herp enthusiasts making the bi-yearly pilgrimage to LaRue-Pine Hills is a ritual. People come from all over the region for a chance to see many species of snakes, turtles, amphibians and lizards. And since this is a time of movement for most of these animals your chance of a sighting is very good.
If interested in going down on the 26th with herp society members, there will be a meet-up to carpool at the Park and Ride lot on the corner of 270 and Gravois rd. Meeting time is 8 a.m. sharp! If you would to prefer to meet at Snake Road, the carpoolers should be down at the north entrance of the road at approximately 10 a.m. Be sure to wear good walking shoes and bring your lunch and beverages as this will be an all day adventure. Remember:
No bags or collection tools allowed!
For info on carpooling please contact Curt Hendricks at guitlizard1@att.net

Here is further information on the area plus rules, regulations and the road closure schedule.
Collection or removal of any animals is prohibited. Gathering, herding, harassing or having any animal in possession is also prohibited.

LaRue-Pine Hills/Otter Pond Research Natural
Area (RNA) became our nation’s 250th RNA in
1991. RNA’s are permanently protected to
maintain biological diversity and to provide places
for research and monitoring of undisturbed natural
areas. More than 1200 species of plants and animals
make their homes in the LaRue-Pine Hills/Otter Pond
RNA. Many are threatened and endangered species.
Northern prairie plants, southern swamp types and
plants typical of the eastern and western forests are all
found here, over 1150 plant species in all. It is one of
only two sites in the state where the native shortleaf
pine grows naturally.
Perhaps this area is most famous for the biannual ‘Snake Migration’ across the LaRue Road at the base of the bluffs,
adjacent to LaRue Swamp. The road is closed to vehicular traffic every spring and fall to help protect thousands of
reptiles and amphibians during their migration between their summer and winter habitats. About 66 percent of the
amphibians and 59 percent of the reptiles known to occur in Illinois are found here (approximately 35 species of snakes).
Approximately 90 percent of the Illinois mammal species and 173 bird species inhabit the RNA. It is an important resting
area for migratory birds and waterfowl. Some unusual animals and birds that make LaRue-Pine Hills their home include
the bobcat, bald eagle, spring cavefish, eastern woodrat, golden mouse, Mississippi kite, and indigo bunting.
Protecting the Reptile and Amphibian Population
The yearly migration involves the hibernation of the animals during the winter months in the bluffs. These animals
then move to their feeding grounds in the swamp during the summer months. Herpetologists have reported that the main
factor in triggering the seasonal migration is ground temperature. This road was open to traffic year-round prior to 1972.
This resulted in the death of many animals that were crossing the road. Consequently, the Forest Service decided to close
a 2.5-mile segment of the road during the seasonal migration to protect the reptiles and amphibians. The road is now being
closed for two months in the spring and fall to further ensure the protection of early or late migrating species. The number
of animals protected by this action is unknown, however, far fewer reptiles and amphibians are found dead on the road.
The closure dates are March 15 to May 15 in the spring and September 1 to October 30 in the fall.
Collecting of any kind is prohibited. The impact of this action on people is minimal. People who want to enter this area of the Shawnee National Forest for
scientific study or recreation are welcome to travel the snake road on foot or by non-motorized methods. Alternate travel
routes are available for the motorized traveler. The closure does not interfere with waterfowl hunting, a popular late fall
activity in the LaRue Swamp.
