Name: Pinus ponderosa / Bouteloua gracilis Woodland
Reference: NatureServe Biotics 2019
Description: This widespread woodland occurs at foothill and lower montane elevations from the southern Rocky Mountains, extending east onto southern Great Plains escarpments, south to the mountains of western Texas, and west to the Colorado Plateau and Mogollon Rim of New Mexico, Arizona and Utah. Sites occur on dry, gentle to steep slopes of all aspects, but are more common on southern and western aspects, especially at higher elevations, which ranges from 1740-2610 m (5700-8550 feet). Substrates are quite variable and include shallow sandy loam soils derived from granitic parent materials, coarse cinder soils, and clayey soil with or without high coarse fragment content. The ground surface is typically characterized by scattered grass patches and litter amid exposed soil. The vegetation is characterized by an open to moderately dense evergreen, needle-leaved tree canopy 10-30 m tall that is typically dominated by <i>Pinus ponderosa</i>. Some stands may be codominated by <i>Pinus edulis</i>. <i>Juniperus</i> spp. may be important subdominants. The shrub canopy is variable and usually low in cover. <i>Ericameria nauseosa, Fallugia paradoxa</i>, and <i>Gutierrezia sarothrae</i> are the most common shrub elements. The typically moderately dense herbaceous layer has greater cover than the shrub layer and is dominated by graminoids. The warm-season, sod-forming shortgrass <i>Bouteloua gracilis</i> dominates the herbaceous layer; <i>Poa fendleriana, Elymus elymoides</i>, and <i>Muhlenbergia montana</i> are all frequent associates but subordinate. Forb cover is typically sparse or well-represented and most commonly includes semi-arid woodland and plains grassland species such as <i>Artemisia carruthii, Sphaeralcea coccinea, Bahia dissecta, Hymenoxys richardsonii, Glandularia bipinnatifida, Lotus wrightii</i>, and <i>Heterotheca villosa</i>.
