Rank Reasons

Endemic to western North America, Sulcaria badia is known only from four groups of sites in California and Oregon, all in maritime areas. It is known historically from Washington. All occurrences but one consist of only a few thalli. Threats to this lichen are land development, air pollution, collections for private herbaria, and any other activity, such as forestry and recreational, that may impact older trees.

Range Extent Comments

Historically, from Washington to California, west of the Cascades (McCune and Geiser 1997). Endemic to western North America. Known extant sites range from Mendocino County in northern California to Benton County in Oregon (Peterson 1998).

Occurrences Comments

Known from four groups of sites in Oregon and California (Peterson 1998). Also known from a Washington site; the lichen appears to be extirpated from this site according to Peterson (1998).

Threat Impact Comments

Increasing threats are land development and air pollution (McCune and Geiser 1997). Collection for herbaria has severely impacted S. badia at its type locality (Peterson 1998). Forest management practices and recreational activities may impact sites.

Ecology & Habitat

Habitat

Occurs on bark and wood of mainly apple, oak, and maple trees in well-lit to partly shaded situations at low elevations. One site is known from a coastal pine forest (McCune and Geiser 1997). The site with the largest quantity of Sulcaria badia is a flat valley dominated by huge oak trees, mainly Quercus garryana. At this site, S. badia appears to be the dominant species, occurring with Usnea cavernosa and Bryoria tortuosa. Elevation from sea level to about 600 m (Peterson 1998).
