Name: Quercus emoryi / Piptochaetium fimbriatum Woodland Reference: Western Ecology Working Group of... Description: This Madrean semi-riparian woodland occurs in the "Borderlands" area of southwestern New Mexico and possibly extends into southeastern Arizona, western Texas and the northern Sierra Madre Occidentale of Mexico. Stands are naturally small, being restricted to elevated alluvial stream terraces on mesic aspects. This association has only been documented from one site in the Animas Mountains at 1770 m elevation. The stand occurs in a narrow valley on a north-facing terrace near an intermittent stream channel. The site is gently sloping (4%) with a sandy alluvium substrate. There is high cover (96%) of plant litter. These late-successional woodlands are dominated by broad-leaved evergreen trees with a sparse shrub layer and a moderately sparse herbaceous layer(<25% cover). The tree canopy is generally between 25-60% cover and is codominated by <i>Quercus emoryi</i> and <i>Quercus arizonica</i> with scattered <i>Juniperus deppeana</i>. The shrub layer consists of scattered shrubs (<10% cover) and often has high diversity. <i>Rhus trilobata, Nolina microcarpa, Garrya wrightii, Juniperus deppeana, Pinus discolor, Cercocarpus montanus, Ericameria laricifolia</i>, and <i>Opuntia imbricata</i> are commonly present. The herbaceous layer is codominated by the perennial grasses <i>Piptochaetium fimbriatum</i> and <i>Bouteloua curtipendula</i>, but is typically very diverse and includes sparse cover of many other grass and forb species. The diagnostic characteristics of this late-successional oak woodland are a moderately dense tree layer that is dominated or codominated by <i>Quercus emoryi</i> with <i>Piptochaetium fimbriatum</i> present to dominating in the herbaceous layer.  Accession Code: VB.CC.32265.CEGL000686 Plot-observations of this Community Concept: 0
