Description
File-based data for download:https://www.sciencebase.gov/catalog/item/632a06dcd34e71c6d67b902fRelated report with figures: https://doi.org/10.3133/ofr20221081Location and extent of the conifer threat across the sagebrush biome in the United States for 2020. Blue areas (dark and light, representing core sagebrush areas [CSAs] and growth opportunity areas [GOAs], respectively) are locations of high sagebrush ecological integrity and could serve as anchor points in an overall biome-wide strategy. A separate, high-resolution portable document format (PDF) version of this map is available at https://doi.org/10.3133/ofr20221081 so stakeholders can zoom in and see the results at much smaller scales. By zooming in, one can see better that conifer threats are occurring at the edges of CSAs and GOAs and are not well represented at a range-wide extent.Conifer woodlands [that is, Pinus edulis (Engelm) (piñon pine) and Juniperus L. spp. (juniper)] have expanded their range in parts of the sagebrush biome, particularly in the Southern Great Basin region (Miller and Rose, 1995; Miller and others, 2000) and the Colorado Plateau ecoregion (Romme and others, 2009; Miller and others, 2019). These shifts are known to have negative effects on greater sage-grouse (Baruch-Mordo and others, 2013; Coates and others, 2017; Severson and others, 2017b) and other sagebrush-associated wildlife populations (Miller and others, 2017; Maestas and others, 2021). Increases in conifer canopy cover result in nonlinear declines in sagebrush cover (Roundy and others, 2014; Miller and others, 2000), which directly reduces the amount of available food and cover for sagebrush-dependent species and thereby increases its relative threat (Maestas and others, 2021).
