Rank Reasons
Ericameria lignumviridis is a shrub endemic to Sevier County, Utah in the western United States. It was described in 1995 from plants that fell into a riparian area from steep rocky slopes above. Due to this confusion and the complications of surveying the treacherous slopes and outcrops, new occurrences were not discovered until 2019 by a United States Bureau of Land Management botanist. There are potentially 13 occurrences known at this time but additional survey and mapping work is needed to confidently delineate the occurrences. Threats are likely low given the inaccessibility of the habitat to humans. Environmental threats are not known. As baseline data are still being compiled, trends also remain unknown.
Range Extent Comments
Ericameria lignumviridis is endemic to Sevier County, Utah in the vicinity of Monroe Mountain (Dustin Rooks, pers. comm., 2019, Welsh 1993).
Occurrences Comments
This species was only known from the type locality which was collected near a riparian area, apparently from a specimen that fell from the steep slopes above. Several newly discovered localities for the species were found in its true habitat of steep volcanic terrain (Dustin Rooks, pers. comm., 2019).
Threat Impact Comments
The threats to this species are assumed to be low since it inhabits extremely steep volcanic slopes above rivers. However, occurrences have only been observed once in 2019.
Ecology & Habitat

Habitat

The habitat for this species was misunderstood for many years and believed to be riparian areas, however it was discovered that specimens had fallen from steep slopes above. The true habitat of this species is steep rocky slopes of volcanic substrates (FNA 2006, Dustin Rooks, pers. comm., 2019).
