Name: Pinus edulis / Muhlenbergia pauciflora Woodland Reference: Western Ecology Working Group of... Description: From Muldavin et al. (2000b): This is a major community of the San Andres and Oscura mountains of New Mexico and is also known from the Sacramento and Capitan mountains that are directly east of White Sands Missile Range. This association typically occurs on cool and steep escarpments at moderate to high elevations (1830-2410 m [6000-7900 feet]). Soils derive mostly from limestone, are moderately shallow, and range from weakly developed aridic Inceptisols to more developed and mesic Mollisols. Soils tend to be fine loamy, but can have 10 to 50% gravel and cobble content at the surface. Caliche or secondary calcium carbonate accumulations are also common. This open woodland is dominated by <i>Pinus edulis</i> with <i>Juniperus monosperma</i> as a subdominant or codominant. Scattered patches of <i>Muhlenbergia pauciflora</i> characterize this type along with other bunchgrasses such as <i>Bouteloua curtipendula</i>, along with <i>Achnatherum scribneri (= Stipa scribneri)</i> and <i>Koeleria macrantha</i> (usually under the trees). Grass cover seldom exceeds 25%, and can occasionally range below 5%. Stands can have a diverse shrubby layer (33 species noted), but shrubs usually do not exceed 10% total cover. <i>Cercocarpus montanus, Quercus x pauciloba (= </i><i>Quercus undulata)</i><i>, Yucca baccata, Rhus trilobata, Gutierrezia sarothrae, Nolina microcarpa</i>, and <i>Opuntia phaeacantha</i> are the most consistent and abundant associates. Several forbs are possible (35+ species), but only <i>Viguiera dentata</i> is moderately constant.  Accession Code: VB.CC.32806.CEGL000785 Plot-observations of this Community Concept: 0
