Long Run Seep

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.
