Long Run Seep

Nature Preserve Area: 
3
County: 
Will
Location and Access: 
In Lockport, take Rte. 171 north from Rte. 7, turn left onto New Ave., continue north 1.5 miles. The nature preserve is on the right between New Avenue and Lemont Road.

Description: 
This preserve contains a calcareous seep representative of the northeastern Morainal Division, a part of Illinois that contains many glacial lakes and other unique wetlands. Within this alkaline wetland, spotted touch-me-not, tussock sedge, skunk cabbage and the shrub nannyberry are common. Due to the calcareous nature of this site, several calcium-loving plants grow here, including grass-of-parnassus, great Angelica, Kalm's lobelia and Riddel's goldenrod. Two exotic plant species, purple loosetrife and glossy buckthorn, are threatening the native plant communities of the seep.
