This species' total known range consists of a few square km on the Arizona-Utah border. It is locally common within this tiny range. Threatened by highway and power line construction, ORV use, displacement by exotic weeds, grazing, and mineral development (Harper 1997 and Stubben 1997, cited by USFWS 2000).
This plant is threatened by off road vehicle use, development, invasive non-native plants, and domestic cattle grazing.
Populations have been reported in 6 locations in Washington County.
For the past decade Astragalus holmgreniorum has been a focus of research in southern Utah. Studies have focused primarily on demography and density within populations of this species. This plant is monitored on an annual basis by the Bureau of Land Management.
A portion of habitat is managed by the BLM, while other populations fall within the boundaries of the school Institutional Trust Land (SITLA).
we must continue to actively find answers regarding the life history of this species. Continued monitoring of populations is important to understand long-term fluctuations.
Due to development, Propagation protocols are important for the survival of this species. Propagated plants may be placed in areas where the habitat is protected.
