Rounded Global Status Rank: G3 - Vulnerable
Reasons: Ephedra antisyphilitica has a more restricted range and a more scattered and isolated distribution within its range than most other Ephedra species. It is generally not dominant or co-dominant within its community. Information on its abundance in Mexico is lacking. There is a definite risk of collection for medicinal and landscaping purposes; although collection is probably not focused on this species, similarity among the various species and general collection of the genus create an indirect danger. Invasive shrubs and livestock grazing also pose potential threats.

Gray ephedra occurs naturally on flats and slopes in all the creosote bush deserts at mostly 1,000 to 4,000 ft (305-1,220 m) elevation and sometimes it is found in the desert grassland up to 5,000 ft. (1,524 m). It inhabits California in the eastern Mojave and Colorado deserts, southern Nevada in Clark and Lincoln counties, southwestern Utah, Arizona in the Grand Canyon area and in the Mojave. It also occurs in Arizona and Colorado deserts, New Mexico along the Gila and Pecos river drainage, TransPecos Texas, the Edwards Plateau, and at scattered locations on the Rio Grande Plain, Baja California to Coahuila and Central Mexico (Benson and Darrow 1981). Characteristic species are creosotebush, white bursage, Joshua tree, blackbrush, catclaw, burrobush, big galleta, Indian ricegrass, black grama, bush muhly, and desert needlegrass.
