Classification
Scientific Name: North-Central Appalachian Seepage Fen
Unique Identifier: CES202.607

© New York Natural Heritage Program
Summary: This system is found in scattered locations in the Central Appalachians and eastern Great Lakes regions. Mostly non-forested, these open fens develop on shallow to deep peat over a sloping substrate, where seepage waters provide nutrients. Conditions are often circumneutral to alkaline. Sedges are the major dominants. Packera aurea, Symplocarpus foetidus, and Lobelia kalmii are among the characteristic forbs. Some of these areas are kept open by grazing, and succession to shrublands may occur in the absence of disturbance.
