Ecological Indicator Information

A shade-tolerant, submontane to montane, circumpolar fern distributed in Pacific, Cordilleran, and Atlantic North America. Occurs on very moist to wet, nitrogen-rich soils within boreal, temperate, and mesothermal climates. Plentiful to abundant (occasionally dominant) in non-forested communities or forest understories on water-receiving (alluvial, floodplain, seepage, and stream-edge) sites; often inhabits water-collecting (swamps and fens) sites. A nitrophytic species characteristic of Moder and Mull humus forms.
