Rank ReasonsThis species is common in most parts of Finland, Norway and Sweden and also occurs in cool to temperate areas of the Northern Hemisphere, South America and North America, Although, the distribution and population sizes of this species are large enough to qualify for G5, the significant decline of the species since pre-industrial times may justify reducing the rank slightly to G4G5.
Range Extent CommentsGlobal distribution "Common in most parts of Finland, Norway and Sweden; less frequent in Denmark [...] Widely distributed in cool to temperate areas of the Northern Hemisphere and southernmost South America" (Tibell 1999). Within North America, widespread in temperate and boreal regions.
Occurrences CommentsNumber of known occurences worldwide is probably > 1000 (including many historic); Number of known occurrences in North America is probably ca. 300 ; Number of known occurrences in California = 6+; Number of known occurrences in Oregon = 29+; Number of known occurrences in Washington = ca. 8+; Number of known occurrences in British Columbia = 67+. Rikkinen (2003?) reports on 32 locations from the region. Although the number of extant occurrences worldwide is unknown, the North American occurrences (collections) are recent and are mostly extant.
Threat Impact CommentsWorldwide, the species has gone through drastic declines since pre-industrial times. The Pacific Northwest, due to logging, has been no exception. However, the rate of loss in the Pacific Northwest has slowed. Although little is known about the reproductive and dispersal biology of this species, it is thought that the species can overcome some habitat fragmentation and, at this point, is secure from extirpation or extinction. However, given the strong old-growth association of this species, it should not be ignored in conservation actions.
