RMRS-GTR-12: A management-oriented classification of pinyon-juniper woodlands of the Great Basin


West, Neil E.; Tausch, Robin J.; Tueller, Paul T. 1998. A management-oriented classification of pinyon-juniper woodlands of the Great Basin. Gen. Tech. Rep. RMRS-GTR-12. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 42 p.

A hierarchical framework for the classification of Great Basin pinyon-juniper woodlands was based on a systematic sample of 426 stands from a random selection of 66 of the 110 mountain ranges in the region. That is, mountain ranges were randomly selected, but stands were systematically located on mountain ranges. The National Hierarchical Framework of Ecological Units (ECOMAP) was used for the highest levels of classification, subdividing the Great Basin into nine relatively environmentally homogeneous Sections. The remaining levels are vegetation-based, focusing on the relative composition and dominance of pinyon and juniper and the dominant shrub and perennial grass species present. This approach will allow managers to better relate the results of previous, as well as new studies and management experiences.

Keywords: pinyon, juniper, vegetation classification, ECOMAP, Ecoregions, management
