Description: This woodland alliance occurs in dry mountain ranges of the Great Basin and southern California, usually on erosional terrain or upper alluvial slopes. Soils are variable, but generally coarse-textured and well-drained. Vegetation included in this alliance is characterized by an open tree canopy dominated by ~Pinus monophylla$, quite often in association with ~Juniperus osteosperma$. ~Pinus monophylla$ may be the sole tree in some cases, or ~Juniperus osteosperma$ may be codominant. In stands that occur in dry ranges of central and southern Nevada, ~Cercocarpus ledifolius$ is a common associate. Less common tree associates include ~Pinus ponderosa, Pinus flexilis, Pinus aristata$, and ~Abies concolor$. In eastern California, ~Pinus jeffreyi$ and~Juniperus californica$ may also be common. The shrub layer is present to moderately dense. Shrub associates may include ~Artemisia tridentata, Artemisia arbuscula, Artemisia nova, Amelanchier alnifolia, Arctostaphylos patula, Quercus gambelii, Prunus virginiana$, and ~Purshia tridentata$. Other shrubs include chaparral species such as~Quercus chrysolepis$ and ~Ceanothus cuneatus$; and ~Quercus turbinella, Arctostaphylos glauca, Eriogonum fasciculatum, Yucca schidigera$, and ~Coleogyne ramosissima$ in southern California. The typically sparse herbaceous layer is usually composed of cespitose perennial grasses, including ~Pseudoroegneria spicata, Festuca idahoensis, Elymus elymoides$, and ~Stipa$ spp. Diagnostic of this woodland alliance is the tree canopy dominated by~Pinus monophylla$ often with ~Juniperus osteosperma$ as a codominant.
