Description: Shrublands included in this alliance have been described in south-central New Mexico, but the alliance is likely to occur in southeastern Arizona, Trans-Pecos Texas and adjacent Mexico. ~Robinia neomexicana$ is considered a semi-riparian species by some researchers. Thickets occur along drainages in canyons at lower elevations (1500-2000 m). On upland sites it is restricted to cooler north aspects at lower montane elevations, but may occur on any aspects at higher montane elevations. Sites are nearly level to moderately steep slopes. Substrate ranges from alluvial deposits on stream terraces to colluvial slopes. Stands have a dense to moderately dense woody layer to 5 m tall that is dominated by the deciduous shrub ~Robinia neomexicana$. ~Quercus gambelii$ may be present but does not codominate. The understory may be dominated by mesic forbs like ~Thalictrum fendleri$, but little other information is available. Stands in the montane conifer zone are considered seral and may have seedlings of ~Pinus ponderosa, Abies concolor$ or conifer species that are colonizing the stand.
