Rank Reasons

The distribution for Platismatia lacunosa is somewhat restricted (it is found only along the western coast of North America). According to McCune and Geiser (1997), this is the rarest of the Platismatia genus in the Pacific Northwest. It occurs from Alaska to California west of the Cascades. It is uncommon in moist riparian forests in the Coastal Range and Cascades where it occurs on branches of Alnus rubra. An estimated 270 sites exist worldwide. This species is sensitive to air pollution, but most sites are not near cities.

Range Extent Comments

Plastimatia lacunosa occurs on the west coast of North America from the Aleutians and southern Alaska to northern California (Culberson and Culberson 1968, McCune and Geiser 1997, Brodo et al. 2001).

Occurrences Comments

90 to 129 sites known in the Pacific Northwest.

Threat Impact Comments

Air pollution sensitive (McCune and Geiser 1997), but sites are not located near cities.
