Wikipedia Abstract

Ephedra nevadensis (Nevada ephedra) is a species of Ephedra native to dry areas of western North America. Its range extends west to California and Oregon, east to Texas, and south to Baja California, including areas of the Great Basin, Colorado plateau and desert Southwest. It is found in rocky and sandy soils, generally in areas without trees. More than other North American Ephedra species, it is a significant forage plant. It is grazed upon by mule deer (Ococolius hemionus), pronghorn (Antilocapra americana), and Desert Bighorn Sheep (Ovis canadensis) as well as domestic sheep.
