Ecological Indicator Information

A shade-tolerant/intolerant, montane to subalpine, circumpolar fern (transcontinental in North America). Occurs fresh to very moist, calcium and nitrogen-rich soils within boreal, wet temperate, and cool mesothermal climates; its occurrence increases with precipitation. Rare to scattered in herbaceous understories on water-shedding and water­receiving (floodplain) sites. Fairly common on Queen Charlotte Islands, locally on coastal mainland. A nitrophytic species characteristic of Moder and Mull humus forms.
