Population Size Comments: Estimated 5000 individuals worldwide.

Number of Occurrences with Good Viability/Integrity: Many (41-125)
Viability/Integrity Comments: Estimated 50 occurrences worldwide with good viability.

Overall Threat Impact: Medium
Overall Threat Impact Comments: Localized substantial threat. This species is widespread in Europe and Scandinavia, but is declining and listed as rare, threatened, or endangered in most countries. Listed as critically endangered in United Kingdom and vulnerable on the European Red Data List. In North America, populations remain robust. Causes for decline include changes in the microclimate of deforested areas, the decrease of decayed wood in forests, and diminishing mesic forest.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Short-term decline 10-30% in Europe, but more or less stable in North America.

Long-term Trend: Decline of 30-50%

Ecology & Life History

Habitat Comments: According to Schofield (1976), in British Columbia at least, the habitat is similar to Buxbaumia aphylla, and the species is found "on moist rotten logs and stumps, and on soil of trail banks in subalpine coniferous forests", and also, "confined to the sub-alpine confier forests from the coast to the Interior of the southern half of the province".
