Parathelypteris noveboracensis
Also called New York Fern
Amauropelta noveboracensis, the New York fern, is a perennial species of fern found throughout the eastern United States and Canada, from Louisiana to Newfoundland, but most concentrated within Appalachia and the Atlantic Northeast. New York ferns often forms spreading colonies within the forests they inhabit.
New York fern is common in sunny patches caused by canopy gaps in mixed woodlands, near vernal seeps, at the edge of swamps, in wooded ravines, and along streams. Once soil pH levels decline below 4.1, this fern can become a dominant understory species. In such situations, it may out-compete the seedlings of certain tree species, some of which are commercially important. The seedlings of Prunus serotina are especially vulnerable, as the fern releases an allelopathic phenol which can kill them.
