Rank Reasons
Eriogonum brachyanthum is an annual herb that is common throughout the western Mojave desert and Great Basin in the western United States. With a large range extent, over 100 occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent Comments
Eriogonum brachyanthum is known from southeastern Oregon, western Nevada, and southern California in the western United States (FNA 2005). Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, it is estimated that there are more than 100 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, Eriogonum brachyanthum is potentially threatened by development, road maintenance, invasive species, livestock management, off-road vehicle use, and other threats.
Ecology & Habitat

Habitat

Eriogonum brachyanthum grows in "sandy to gravelly flats, washes, and slopes, saltbush, greasewood, and sagebrush communities, pinyon-juniper and montane conifer woodlands" (FNA 2005).
