Type Concept: This mesquite shrubland association is currently described from Grand Canyon National Park in Arizona. It is also reported from Nevada, California, Texas and possibly New Mexico. More survey and classification work are needed to fully characterize this type. It occurs most commonly along the Colorado River corridor above the old high-water line, but also in large tributary canyons along drainage channels and on adjacent sideslopes. It typically occurs at 375 to 850 m (1225-2825 feet) elevation, but has been observed at up to 1050 m (3475 feet). It occurs on gentle to moderate gradients (up to 20°), across all aspects other than south-facing. When found on sideslopes, it typically occurs on low slopes or toeslopes. Soils are well- to rapidly-drained sandy loams. Some stands support notable cryptogamic soil crust. This association is characterized by pure and fairly dense stands of tall-shrub or small-tree Prosopis glandulosa var. torreyana, which can reach 75% cover in dense stands. Encelia farinosa occasionally occurs in the short-shrub layer, while various other species, including Baccharis sarothroides, Pluchea sericea, Isocoma acradenia, Atriplex canescens, and Ephedra spp., occur less frequently. Dwarf-shrubs are essentially absent. Exotic Bromus rubens and the native annual Vulpia octoflora dominate the graminoid understory when it occurs, although it is not present in all stands. Forb composition is quite variable.
