Name:
Quercus turbinella - Arctostaphylos pungens - Ceanothus greggii Warm Interior Chaparral Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This interior chaparral macrogroup occurs across central Arizona (Mogollon Rim) and southern New Mexico, east in mountains across Trans-Pecos Texas, and south into the Madrean Occidentale and Madrean Oriental in northern Mexico. Occurrences are also found in desert mountains in the Sonoran and Mojave deserts. The vegetation is characterized by a moderate to dense evergreen shrub layer less than 3 m tall that is dominated by scrub oak and sclerophyllous shrubs. Widespread diagnostic species <i>Quercus turbinella, Arctostaphylos pungens</i> or <i>Ceanothus greggii</i> frequently dominant large areas. Other characteristic shrubs include <i>Cercocarpus montanus var. paucidentatus, Garrya wrightii, Quercus toumeyi</i>, and <i>Rhus trilobata</i> with <i>Arctostaphylos pringlei</i> and <i>Arctostaphylos pungens</i> at higher elevations. In desert chaparral stands in the western extent, <i>Arctostaphylos glauca, Arctostaphylos patula, Cercocarpus montanus var. glaber, Eriodictyon angustifolium, Garrya flavescens, Juniperus californica, Nolina parryi, Quercus berberidifolia, Quercus cornelius-mulleri, Quercus john-tuckeri, Rhamnus ilicifolia</i>, and <i>Rhus ovata</i> characterize this shrubland. In the eastern extent, stands in the Chihuahuan Desert mountains and the Sierra Madre Oriental are dominated by evergreen shrub oak species, such as <i>Quercus mohriana, Quercus pungens</i>, and <i>Quercus vaseyana</i>, and several widespread chaparral species, such as <i>Arctostaphylos pungens, Ceanothus greggii</i>, and <i>Garrya wrightii</i>. Additional characteristic Madrean species are may be present such as <i>Arbutus xalapensis, Fendlera rigida, Garrya ovata, Purshia mexicana, Rhus virens var. choriophylla</i>, and several species of <i>Salvia</i>. The herbaceous layer variable, but is generally composed of semi-arid perennial grasses. Stands are found on foothills, xeric mountain slopes and canyons in hotter and drier habitats and often dominate along the mid-elevation (1000-2500 m) transition zone between desert scrub and montane woodlands. Sites are often steep and rocky.
