HABITAT TYPES AND PLANT COMMUNITIES:

Mesa dropseed is a component of desert scrub, shrub, grassland, sagebrush (Artemisia spp.) and pinyon-juniper (Pinus-Juniperus spp.) communities [3,46]. Wolters and others [47] placed it in the transition zone between desert scrub and desert grassland. Mesa dropseed is also a component of the mesquite-dropseed-broom snakeweed (Prosopis spp.-Sporobolus spp.-Gutierrezia sarothrae) and broom snakeweed-dropseed communities [4,9]. It has become a dominant grass species in fragmented black grama (Bouteloua eriopoda) stands [15] and is associated with soaptree yucca (Yucca elata) [6,32].
