Ecological Indicator Information

A shade-intolerant, submontane to subalpine, Western North American fern-ally distributed equally in the Pacific and Cordilleran regions. Occurs on very shallow, very dry to moderately dry, nitrogen­poor soils within boreal, temperate, cool semiarid, and cool mesothermal climates. Its occurrence decreases with increasing latitude, elevation and precipitation. Commonly scattered in non-forested communities on very shallow soils on rock outcrops. Usually associated with Arctostaphylos uva­ursi, Cryptogramma crispa, Rhacomitrium canescens, and lichens. Characteristic of moisture-deficient sites.
