PH Library, NRC Host Program On Lake In The Hills Nature Preserve

The Prospect Heights Natural Resources Commission (PH-NRC) and the Prospect Heights Public Library will be co-sponsoring another program called “Lake in the Hills Fen” by David Schwaegler from 7-8:30 p.m. on Thursday, April 21.

Schwaegler has volunteered at Lake in the Hills Fen since the late 1980s before the natural area achieved Illinois Nature Reserve status. His many roles include bird watching, butterfly monitoring, conducting plant inventories, phenology studies, tour guide and nature steward, among others.

Like many native grasslands in Illinois, the 500-acre site has had a hectic path to becoming a natural preserve despite the rare and irreplaceable flora and fauna that exist at this site.

A total of nine unique and distinct native communities make up this ecosystem – limestone floating mat, graminoid bog, shrubby fen, hanging bog, limestone seep, sedge meadows and marshes, perennial stream, gravel meadow dry and mesic gravel prairie.

He will take a picture tour through this landscape and learn firsthand about the history and the people who fought so hard to preserve it.

The program is free but register by visiting as it will take place virtually through the library’s Zoom platform. Instructions for logging into the program will be emailed to registrants on the day of the program. The program will also be taped and encore presentations will air at future dates and times.
