Pinyon-juniper woodland

Pinyon-juniper woodland, also spelled Piñon-juniper woodland, is a vegetation type (biome) of Western United States higher elevation deserts, characterized by being an open forest dominated by low, bushy, evergreen junipers (Juniperus osteosperma,Juniperus californica,Juniperus grandis), pinyon pines (Pinus monophylla,Pinus edulis), and their associates which vary from region to region. The woodland's crown height may vary from less than 10 meters up to 15 meters, depending on the site. It may consist of pure stands of pinyon pine, or pure stands of juniper.

The Pinyon-juniper woodland range spans from New Mexico, to the eastern Sierra Nevada, the Colorado Plateau, the Great Basin, and higher elevations of Mountain ranges of the Mojave Desert. The woodland's range includes the Mogollon Rim in the south, to its northern extent in the Snake River Plain.

The Pinyon-juniper woodland is one of the most prevalent types of coniferous woodland in northern Arizona and New Mexico.

The pinyon-juniper plant community covers a large portion of Utah and the Canyonlands region. singleleaf ash (Fraxinus anomala), and Utah serviceberry (Amelanchier utahensis) are codominants of pinyon pine and Utah juniper in this region. in this region, the community occurs on rocky soils or jointed bedrock.
