Single-leaf pinyon–Utah juniper woodland in northeastern Nevada near Overland Pass at the south end of the Ruby Mountains. Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a biome found mid-elevations in arid regions of the Western United States, characterized by being an open forest dominated by low, bushy, evergreen junipers, pinyon pines, and their associates.
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, the community occurs on rocky soils or jointed bedrock. [5]
The pinyon pines and juniper trees that fill the high desert, seen by many as an invasive scourge, are drawing interest as a source of renewable energy. Love them or loathe them, pinyon-juniper ...
The main plant communities, or zones, are woodlands, mountain woodlands, and grassland and shrub. The woodland zone, or pinyon-juniper woodland, covers the largest area.. It consists of open woodlands of short trees, mostly pinyon pine (Pinus edulis throughout the ecoregion, and Pinus monophylla subsp. fallax in the southwestern portion of the ecoregion) and species of juniper (Juniperus spp
In the Owens Valley, the Foothill Woodland Zone is replaced by a Pinyon-Juniper Woodland Zone, characterized by single-leaf pinyon pines and sierra junipers. The underbrush contains big sagebrush (Artemisia tridentata) and blackbrush (Coleogyne ramosissima). Jeffrey pines may occur along streams.
A rare and endemic wildflower, the Walker Pass milkvetch (Astragalus ertterae) of the pea family, grows within the Pinyon-Juniper woodland. It grows in the sandy-loamy to granitic soils associated with pinyon pines and canyon live oaks. It is primarily found on west-facing slopes from 5,600 to 6,200 feet (1,700 to 1,900 m) elevation.
The pinyon–juniper woodland has a broader elevational range in the carbonate areas of eastern Nevada than elsewhere in Great Basin montane forests, even extending onto the floors of the higher basins, partially because of greater summer precipitation. Both pinyon pine and juniper decline north of this ecoregion.
Short-statured pinyon pine and Utah juniper trees with an understory of shrubs and grasses comprise the pinyon-juniper woodland community, occupying dry slopes, hills and mesa tops. Common understory plant species include Gambel oak, big sagebrush, Indian ricegrass, western wheatgrass, galleta and blue grama.
