Rank ReasonsAbundant in the Pacific Northwest and also found in other parts of North America. Found in Europe as well, but considered threatened throughout its European range.
Range Extent CommentsA low arctic-temperate circumpolar species (Krog 1968). In North America, found from coastal CA (one site) to AK and east of the Rockies in BC and AB. In AK: in the East and Central Pacific Coast District, AK Range District, Central Yukon River District, Bering Sea District and Bering Strait District. Also found in eastern Canada and the northeastern U.S., and in CO and NM (Brodo et al. 2001). In Germany in montane and high-montane oceanic, mild but cool areas (about 1/2 the populations are extinct (Wirth 1995). Also in other parts of northern Europe. Found in Iceland (Kristinsson 1980).
Threat Impact CommentsConsidered to be threatened in its entire distribution area in Europe. (Clerc et al 1992). The genus Nephroma is sensitive to air pollution (PNW Lichen sensitivity ratings by species). In Sweden: "the lichen species recorded were significantly correlated with the presence of large, old deciduous broad-leaved trees, Deciduous broadleaved woods with many old trees are at present being rapidly transformed into forest plantations. The recorded lichen species will decrease unless the woods are protected or have modified management" (Gustafsson 1992).
