Pinyon-juniper woodlands of the Great Basin: distribution, flora, vegetal cover
Research Paper, Intermountain Forest and Range Experiment Station, USDA Forest Service
Dot grid analysis of maps from LANDSAT-1 photographs showed that approx. 7.1 million ha of pinyon-juniper are found in the Great Basin. A list is given of 240 plant species identified in the area (5 trees and 67 shrubs). Total vegetative cover increased with altitude. Juniperus osteosperma was more frequent at lower, drier sites, whereas Pinus monophylla and P. edulis were more frequent at higher altitudes.
