Long Run Seep Nature Preserve
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.
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.
