LaRue Swamp

Nature Preserve Area: 
Location and Access: 
From the town of Wolf Lake on Highway 3, take Highway 3 north 3 miles to a county road. Turn east on the county road and go 1 1/4 mile to where the road comes to a "T" at the base of the bluff. Turn south on the road and go 1/4 mile. The preserve is south and west of the road.

La Rue Swamp in combination with the adjacent Pine Hills is one of the richest, most biologically diverse areas in Illinois. The Pine Hills/La Rue Swamp area contains 43% of all the plant species known from Illinois. The preserve contains mesic floodplain forest, shrub swamp and pond communities once characteristic of the Mississippi River bottomlands of southern Illinois, but now nearly all cleared and drained. The primary source of the swamps' water is runoff from west - facing wooded slopes and bluffs of the adjacent Pine Hills and from springs along the base of the bluffs. Some of the rare, relic or unusual species that occur in the preserve are golden mouse, green water snake, bluehead shiner, and bantam sunfish.

La Rue Swamp has been designated a National Natural Landmark.
