The distribution and abundance of conifers in sagebrush (Artemisia spp.) ecosystems of the Great Basin in the Western United States has increased substantially since the late 1800s. Encroachment of these trees can also present significant threats to populations of sagebrush obligate species, such as greater sage-grouse (Centrocercus urophasianus). Accordingly, baseline tools are needed to allow better understanding of factors influencing conifer encroachment into sagebrush ecosystems. Such tools also help facilitate informed management decisions aimed addressing the threats to populations of greater sage-grouse. To meet this need, WERC scientists have developed a suite of spatial products derived from high resolution...
