Long Run Seep Nature Preserve

Long Run Seep is a high-quality fen—a term often used interchangeably with "seep"—that is situated on the east terrace of the Des Plaines River. Three species on the Illinois list of endangered or threatened species occur here, and the site is considered a likely candidate to be a breeding site for Hine's emerald dragonfly (HED), a federally-listed species. Indian plantain, marsh blazing stars, marsh skullcaps and many other plants indicative of high quality wetlands thrive in the fen.
