extensively in the Great Basin Region, from the southwest corner of Wyoming and

Green ephedra is a constituent in a
variety of plant associations but is rarely referred to as a dominant or
subdominant species.
It has, however, been identified as a dominant on the upland bench of
Chaco Canyon, New Mexico in the galleta (Hilaria jamesii)-blue
grama (Bouteloua gracilis)-fourwing saltbush(Atriplex
canescens) vegetation type [20], and in a cold desert community of Wupatki National Monument in northern
Arizona [15]. It has also been identified as a dominant in some sagebrush (Artemisia spp.)-grasslands [6]
and pinyon (Pinus spp.)-juniper (Juniperus spp.)
woodlands [10,30,89,91]. It is often present with
low or moderate occurrence in Joshua tree (Yucca brevifolia) [66,99], blackbrush (Coleogyne
ramosissima)
[9,14,32,43,65,73,100,101] desert shrub [13,15,23,35,61,71,72,74,91,98,99,100], sagebrush [7,41,54,56,64,65,72,74,88,93,99,100,101,105,106,108], desert
grassland [58,65,99,100,101,102], and pinyon-juniper communities
[3,13,18,39,42,54,55,61,64,69,74,79,80,86,99,104,106,108].
