Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

There are very few known populations of Sulcaria badia and negative impacts to the species from increasing residential and agricultural development have been documented. Additionally, two populations have already been reported as extirpated.


Geographic range

This species is endemic to the west coast of the United States and is found from Washington to northern California.


Population and Trends

This species was originally known from Washington, Oregon and California. However, the Washington population has not been successfully relocated (Peterson et al. 1998) and further searching did not result in any newly discovered populations in that area (Carlberg 2006).

Population Trend: Deteriorating


Habitat and Ecology

This species grows predominantly on Gary oak and cherry trees (Brodo and Hawksworrth 1977), but has also been found on many other tree species (Carlberg 2006).

Temperate Forest

Threats

This species is most threatened by habitat loss due to increasing agricultural and residential areas as well as the increased air pollution (Peterson et al. 1998).

Conservation Actions

Ensuring that populations of this species are not affected by any increasing human residential and agricultural development is essential. Additionally, it should be listed in the United States as an endangered species. Additionally, education and training of land managers and local botanists to identify the species should be conducted, and contracted experts should be hired to conduct detailed monitoring at various time intervals (every 5 to 10 years).

Research needed

Research on the population size and genetics would greatly enhance our understanding of this species. Additionally, long-term monitoring projects need to be conducted.
