    The pinyon-juniper woodland ecosystem complex is highly variable across the western landscape, as is bird community composition. We investigated relations between breeding birds and vegetation characteristics in modified pinyon-juniper woodlands at three sites (BLM, USFS, NPS) on the Colorado Plateau. It is widespread and often abundant in this region, forming extensive open woodlands, usually mixed with junipers in the pinyon-juniper woodland plant community. The Colorado pinyon (piñon) grows as the dominant species on million acres (19, km 2 or 7, sq mi) in Colorado Clade: Tracheophytes.

      We investigated relations between breeding birds and vegetation characteristics in modified pinyon–juniper woodlands at three sites (BLM, USFS, NPS) on the Colorado Plateau. During the breeding seasons of and , we surveyed birds and measured vegetation in 74 study plots.

Many reptiles also rely on the pinyon-juniper ecosystem for habitat [55]. Seventy-three different bird species breed in pinyon-juniper habitat woodlands.

Price New from Used from Author: Mark. Zarn. Piñon-Juniper Woodlands. Major Species. The most common species within piñon-juniper woodlands are Colorado piñon pine (Pinus edulis) and Utah (Juniperus osteosperma) and one-seed (Juniperus monosperma) juniper, although Rocky Mountain juniper (Juniperus scopulorum) may codominate or replace one-seed juniper at high elevations.

Piñon-juniper woodlands account for just over 5 million. Covering as much as 15% of the land area in 5 states—Arizona, Colorado, Nevada, New Mexico, and Utah—pinyon-juniper woodlands provide a wealth of resources and ecosystem services, from wildlife habitat and vegetative cover for watershed protection, to pinyon nuts and fuelwood (Gottfried et al.

The pinyon and juniper type is widespread on the Colorado Plateau, occurring between 5, to 7, feet in elevation. Range, species composition, structure, and stand characteristics are influenced by moisture availability and precipitation patterns.

Pinyon-Juniper Habitat. In Colorado, pinyon-juniper ecological systems may occur as shrublands or woodlands. These systems are typically found at lower elevations (ranging from 4, – 8, ft) on dry mountains and foothills of the Colorado Plateau region on the Western Slope.

Pinyon-juniper also occurs in a limited distribution on the eastern plains near the Purgatoire River. Pinyon-juniper may exist on deeper valley soils, buttree size and density increase as elevation increases and soil depth decreases (Vasek andThorne ).

Characteristic landforms include gently rolling hills to steep mountainslopes, rocky canyons, and narrow ridges (Bradley and Deacon ). In Santa Fe, New Mexico. The Pinyon-juniper woodland is one of the most prevalent types of coniferous woodland in northern Arizona and New Mexico.

In Arizona the great basin woodland species are Juniperus arizonica, Juniperus californica in western Arizona, Juniperus deppeana, Juniperus monosperma, Juniperus osteosperma, Juniperus scopulorum at higher elevations, Pinus monophylla var.

Pinyon-juniper (Pinus spp.-Juniperus spp.) communities occupy areas in 10 states of the Great Basin (to 42°N), the Colorado Plateau, the Rocky Mountains, and the Sonoran and Chihuahuan Deserts (Figure 1).It extends southward to the states of Jalisco and Puebla in Mexico (to 18°N).

Pinyon and juniper trees grow together and tolerate a broad range of environmental. GENERAL DISTRIBUTION: Pinyon-juniper woodlands cover more than million acres in the western U.S. [].Singleleaf pinyon has a large area of distribution and, therefore, probably a large degree of genetic variation [].It is the predominant tree species in the isolated mountain ranges of the Great Basin, ranging from southern Idaho, western Utah and northwestern Arizona, through most of.
