Name: Pinus leiophylla / Piptochaetium fimbriatum Woodland
Reference: Western Ecology Working Group of...
Description: This Madrean conifer woodland occurs in the mountains of southeastern Arizona, southwestern New Mexico and possibly northern Mexico. Stands are naturally small and patchy in distribution being restricted to flat to gently sloping streamsides and alluvial benches along drainages and washes. Elevation is roughly 1520-1830 m. Soils are fluventic and derived from alluvial sediments. The open to moderately dense (25-60% cover) tree canopy has an overstory of Pinus leiophylla (8% cover), with a subcanopy codominated by Pinus discolor (10%) and Juniperus deppeana (13%) with evergreen oaks present such as Quercus arizonica or Quercus X organensis [arizonica X grisea] hybrid, Quercus hypoleucoides, and Quercus emoryi. Occasional Platanus wrightii, Juglans major, Prunus serotina, and Fraxinus velutina may also occur in the tree canopy. The shrub layer is typically moderately dense (>25%) and is dominated by tree regeneration and shrubs such as Quercus toumeyi, Quercus rugosa, and Rhus trilobata. Other species, including Arctostaphylos pungens, Nolina microcarpa, Frangula betulifolia, Garrya wrightii, and the vine Vitis arizonica, are also present in low cover. The moderately dense herbaceous layer (25-60% cover) is dominated by the perennial grass Piptochaetium fimbriatum. Aristida schiedeana var. orcuttiana (= Aristida orcuttiana), Bouteloua curtipendula, Bouteloua gracilis, Bromus porteri (= Bromopsis porteri), Carex geophila, and Muhlenbergia longiligula are also common, but the herbaceous layer is typically very diverse and includes sparse cover of many other grass and forb species. The Pinus leiophylla overstory and Piptochaetium fimbriatum-dominated herbaceous layer are diagnostic of this late-successional woodland.
