Rank Reasons

Eriogonum hirtellum is known from 10 recent occurrences and 19 occurrences that haven't been seen recently (Del Norte and Siskiyou counties, California) in the Klamath National Forest. This taxon is a strict serpentine endemic. It is threatened by disturbance from roads, quarry building, burning, and possibly from grazing. There are also historic impacts from logging.

Range Extent Comments

Currently known from Del Norte and Siskiyou Counties in California (California Native Plant Society 2012). There are reported occurrences in Oregon but these are not confirmed (S. Vrilakas, pers. comm. 2012).

Occurrences Comments

There are 30 mapped occurrences, but 1 is confirmed extirpated (CNDDB 2016).

Threat Impact Comments

Threats include ORVs, logging, grazing, and roads (CNDDB 2016). Threatened by road and quarry development, fire line construction, disruption of natural fire regimes, and historic impacts from logging (M. Knight, pers. comm. 2012; R. Bittman, pers. comm. 2012).

Ecology & Habitat
