Name: Pinus ponderosa / Arctostaphylos patula Woodland
Reference: Western Ecology Working Group of...
Description: This woodland association has been reported from the mountains and plateaus in Colorado, Utah and California. Elevation ranges from 1770-2600 m (5800-8500 feet). Sites are dry, warm, mid to lower slopes, benches and ridges often with southerly aspects. Soils are typically sandy loams but vary from sand to silt loam. Parent materials are sandstone, limestone and occasionally basalt and andesite. The tree canopy is typically open (about 30% cover), but can range from 10-80% cover and is dominated by Pinus ponderosa. Scattered Juniperus scopulorum trees may also be present. Arctostaphylos patula dominates the moderate to sparse shrub layer. Others shrub species present may include Amelanchier utahensis, Ceanothus spp., Cercocarpus montanus, Mahonia repens, Purshia tridentata, Quercus gambelii, Symphoricarpos oreophilus, and Tetradymia canescens. The sparse herbaceous layer (<20% cover) is primarily composed of graminoids such as Carex rossii, Achnatherum hymenoides (= Oryzopsis hymenoides), Elymus elymoides, Leymus salinus (= Elymus salinus), and Poa fendleriana. Forbs are sparse and may include Achillea millefolium, Balsamorhiza sagittata, and Eriogonum racemosum.
