| Description: | This open woodland and savanna alliance is characterized by diagnostic tree species Pinus monophylla that forms an open to moderately dense tree layer often with Juniperus osteosperma or, less frequently, Juniperus californica in southern California, with an understory dominated by an open to dense layer of perennial grasses and lacking significant cover of shrubs. It occurs on dry mountain slopes, foothills, plateaus and ridges in the Great Basin region and eastern foothills of the Sierra Nevada, and south in scattered locations throughout southern California, including desert mountain ranges. |
