File-based data for download: https://www.sciencebase.gov/catalog/item/632a33ced34e71c6d67b914fRelated report with figures: https://doi.org/10.3133/ofr20221081Location and extent of three mapped threats (invasive annual grasses, expanding conifers, and human modification) with core sagebrush areas and growth opportunity areas across the sagebrush biome of theUnited States for 2020. Blue areas (dark and light, representing core sagebrush areas [CSAs] and growth opportunity areas [GOAs], respectively) arelocations of high sagebrush ecological integrity and could serve as anchor points in an overall biome-wide strategy.Sagebrush foliage percent cover is a definitive characteristic of the ecosystem and relevant to persistence of most sagebrush-associated animal species studied, such as greater sage-grouse (Connelly and others, 2011), sagebrush-obligate songbirds (Knick and Rotenberry, 1995; Earnst and Holmes, 2012; Carlisle and others, 2018), and pygmy rabbits (Smith and others, 2019). Fragmentation and loss of formerly large and contiguous sagebrush patches are primarily the result of altered fire regimes, annual grass invasion, conifer woodlands expansion, and various human land uses—trends that profoundly alter the composition, structure, and function of the ecosystem (table 2; Knick, 1999).
