Acer grandidentatum - Quercus gravesii - Quercus muehlenbergii Forest & Woodland Alliance
Reference:
NatureServe Biotics 2019
Description:
Stands in this forest and woodland alliance occur in mesic canyons of the Chisos Mountains and Guadalupe Mountains of Trans-Pecos Texas and New Mexico. The tree canopy is dominated by deciduous tree species <i>Acer grandidentatum</i> and <i>Quercus gravesii</i> or <i>Quercus muehlenbergii</i>, which are diagnostic. Other characteristic species sometimes present include the deciduous <i>Ostrya chisosensis</i> and <i>Quercus graciliformis</i>, and the evergreen <i>Arbutus xalapensis, Hesperocyparis arizonica, Juniperus deppeana, Juniperus flaccida, Pinus cembroides, Pinus edulis, Pinus ponderosa var. scopulorum, Quercus grisea, Quercus emoryi</i>, and <i>Quercus rugosa</i>. The shrub and herb strata are relatively sparse. Associated shrubs that may be present include <i>Agave havardiana, Agave parryi ssp. neomexicana, Ceanothus greggii, Crataegus tracyi, Dasylirion leiophyllum, Garrya ovata, Mahonia haematocarpa, Nolina erumpens, Salvia regla</i>, and <i>Vitis arizonica</i>. Associated herbaceous species include <i>Bothriochloa laguroides ssp. torreyana, Bouteloua curtipendula, Muhlenbergia rigida, Piptochaetium fimbriatum, Poa strictiramea</i>, and <i>Schizachyrium scoparium</i>. These woodlands occur along drainage channels, sometimes occupying benches, terraces, and adjacent lower slopes, often in coarse, rocky substrate. It occurs in the most sheltered habitats, on upper stream terraces and canyonheads. These communities grade to slightly less mesic mixed evergreen-deciduous forests and woodlands.
