Known from Uintah Co., Utah and Mesa Co., Colorado. The plant primarily occurs sporadically over a 30 mile range in Uintah County, Utah. Astragalus desperatus var. neeseae grows on sand and sandy silt soils and is a component of the salt-desert shrub vegetative community. It is threatened by habitat destruction from off-road vehicle use, as well as from road, pipeline, and well site construction in connection with anticipated oil and gas development.
