Rank Reasons
Peraphyllum ramosissimum is species within a monotypic genus of shrubs endemic to North America where it is known from the interior West. With a large range extent, more than 80 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Peraphyllum ramosissimum is a species endemic to the United States, from eastern Oregon, south to eastern California, and east to Utah, western Colorado, western Idaho, and northern New Mexico (Idaho Native Plant Society 1993, FNA 2014).
Occurrences Comments
By applying a 1 km separation distance to herbarium records, Idaho Native Plant Society records, and photo-based observations documented between 1993 and 2024, there are estimated to be between 81 and 300 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024, Idaho Native Plant Society 1993).
Threat Impact Comments
Although threats are not widely documented, Peraphyllum ramosissimum is potentially threatened by development, road maintenance, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

This species grows on dry hillsides, mostly in full sun, in oak-sagebrush, pinyon-juniper, mountain brush, and ponderosa pine communities (FNA 2014).
