Sideling Hill Creek

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.


Two hour drive from Baltimore and Washington, D.C., past the Sideling Hill Creek Interpretive Center.

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
  • In 1998, 40 volunteers restored 3 acres of stream buffer with 1,200 native tree saplings
  • 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.
  • Twelve rare, endemic (occurring only on the shale barrens and nowhere else) plants including the nationally-endangered evening primrose, shale ragwort, and Kate's mountain clover.

What to See: Animals

  • Olympian marble butterfly, green floater mussel, tiger beetle
  • Wild turkey, hawks, and bobcat.
