Name: Pinus discolor / Quercus hypoleucoides Woodland Reference: Western Ecology Working Group of... Description: This Madrean conifer woodland occurs the Animas, Peloncillo, Chiricahua and Santa Catalina mountains in the 'Borderlands' of southwestern New Mexico and southeastern Arizona, and probably occurs in the mountains of adjacent northern Mexico. Stands are small and patchy and limited to elevated plains, mountain and foothills slopes, and ridgetops. Elevation ranges from 1890-2130 m. Soils are shallow and rocky, often with rock outcrops. This late-successional woodland association has an open tree canopy (>25% cover), codominated by the evergreen trees Pinus discolor and Juniperus deppeana, with occasional Pinus ponderosa or Pinus leiophylla present. The moderately dense to dense shrub layer (>25% cover) is dominated by the broad-leaved evergreen oaks Quercus hypoleucoides and Quercus rugosa, but includes many other shrub species such as Arctostaphylos pringlei, Arctostaphylos pungens, Garrya wrightii, Nolina microcarpa, Agave parryi, Rhus trilobata, and Quercus gambelii. The herbaceous layer is generally sparse and composed of mixed grass and forb species including Aristida schiedeana var. orcuttiana (= Aristida orcuttiana), Bouteloua curtipendula, Elymus arizonicus, Muhlenbergia emersleyi (low elevations), Geranium caespitosum, and Thalictrum fendleri. The presence of Quercus hypoleucoides in a moderately dense shrub layer is diagnostic of this Pinus discolor woodland type.  Accession Code: VB.CC.21886.PINUSDISCOLORQU Plot-observations of this Community Concept: 0
