Name: Juniperus monosperma / Bouteloua eriopoda Open Woodland
Reference: NatureServe Biotics 2019
Description: This association is occurs in north-central to south-central and southwestern New Mexico. At present, it has only been described in New Mexico, but unconfirmed reports also place it in the Trans-Pecos region of Texas and in southeastern Arizona. Stands occur on gentle hillslopes and rolling plains, on moderate to very steep foothills, canyon slopes and escarpments (26-65%) and lower elevation mountain escarpments. It can also extend down onto the upper piedmont slopes of the lower valleys and occasionally into basins. Elevation ranges from 1460-2100 m (4800-6900 feet) on all aspects; however, lower elevation slopes are generally restricted to cooler north-facing slopes, and higher elevation stands are restricted to warmer southerly aspects. Soils are typically shallow, gravelly or rocky and derived from basalt, rhyolitic tuff, sandstone, limestone, and occasionally granitic or pumice parent materials. The ground surface is rocky and/or gravelly with scattered grass bunches and litter. Vegetation is characterized by an open to very open tree canopy (10-40% cover) of mature <i>Juniperus monosperma</i> forming an woodland or savanna. Saplings or seedlings are also common. Occasionally mature individuals, seedlings or saplings of <i>Pinus edulis</i> can be present. The herbaceous layer is characteristically grassy with the diagnostic <i>Bouteloua eriopoda</i> dominant and well-represented to abundant. <i>Bouteloua gracilis, Bouteloua curtipendula</i>, or <i>Bouteloua hirsuta</i> may be present but clearly not dominant. Forbs are scattered and variable; the most common species are <i>Astragalus lentiginosus, Ipomopsis longiflora, Mirabilis multiflora</i>, and herbaceous species of <i>Artemisia</i>. Shrubs are poorly represented or absent; the ruderal subshrub <i>Gutierrezia sarothrae</i> and succulents such as <i>Cylindropuntia imbricata, Opuntia phaeacantha, Opuntia polyacantha</i>, and <i>Yucca elata</i> are the most frequent.
