Discussion
Of conservation concern.
Eriogonum concinnum is locally common on the mesas of the U.S. Department of Energy’s Nevada Test Site east and north of Beatty, Nye County. Although the area is subject to considerable habitat destruction, the species seems to be surviving and is neither threatened nor endangered, although it is properly considered a “sensitive” species given its limited range and the potential for more profound habitat destruction in the area.
