Why You Should Visit
Originating from the southwestern mountains of Pennsylvania, Sideling Hill Creek tumbles its way down the steep, forested, shale cliffs of western Maryland before it finally spills into the Potomac River. The preserve has several trails so visitors can explore the variety of species and natural communities that exist at Sideling Hill Creek Preserve. Admission is free.

Why the Conservancy Selected This Site
Sideling Hill Creek is one of the most pristine streams in Maryland, which helps support the globally-rare harperella population. In addition, the occurrence of the rare shale barren communities prioritizes this site as a focus for the Maryland/D.C. Chapter's efforts.
What the Conservancy Is Doing Here
- 704 acres purchased or under easement by The Nature Conservancy since 1992
- Annual trail spring cleaning in late April
- Studying and monitoring the shale barren communities
- Leasing hayfields to local farmers to demonstrate compatible agricultural practices
- Preventing sedimentation of stream
- Removing non-native weeds on the shale barren - volunteers welcome!
- Monitoring the stream for sediment, pollutants and excess nutrient runoff
What to See: Plants
- The world's healthiest population of the globally-rare aquatic wildflower, harperella.
