The Nature Conservancy staff, along with our devoted volunteer stewards, work to stem the invasion of autumn olive (Elaeagnus umbellata), an exotic species threatening to crowd out native plant species.
Rare bryophytes and ferns that occur here have made this site exciting to botanists, both professional and amateur alike. Sphagnum moss is slowly filling an abandoned sandstone quarry in the northern part of the preserve while other species of mosses and liverworts can be found on cliff walls and the forest floor. Mayapples, Jack-in-the-pulpit, blue phlox and yellow celandine poppy can also be found the the woodland's understory.
The preserve is open for hiking - a trail does exist on the preserve - photography, and bird watching on its moderate to rugged terrain. Rock climbing and rappelling are not allowed. Please note that the preserve is gated to keep vehicles out. Simply walk around the gate. For more information please consult the Conservancy’s Preserves Visitation Guidelines.
