Human Modification 2020 (Fig. 11) - A Sagebrush Conservation Design to Proactively Restore America?s Sagebrush Biome

Blue areas (dark and light,<br/>representing core sagebrush areas [CSAs] and growth opportunity areas [GOAs], respectively) are locations of high sagebrush ecological integrity<br/>and could serve as anchor points in an overall biome-wide strategy. A separate, high-resolution portable document format (PDF) version of this map<br/>is available at https://doi.org/10.3133/ofr20221081 so that stakeholders can zoom in and see the results at much smaller scales. By zooming in, one can<br/>see better that human modification threats are occurring at the edges of CSAs and GOAs and are not well represented at a range-wide extent.<br/><br/>Human modifications to natural ecosystems, including landcover conversion for urban, agricultural, and energy development, also reduce SEI at local and landscape scales. Human modification to and land-use change of sagebrush ecosystems have altered or removed native vegetation cover over millions of acres (Reeves and others, 2018). Landcover conversion and modification of natural ecological processes across the ecosystem vary in extent and severity and include agriculture, urban development, resource extraction and energy development (for example, hard rock mining, and oil and gas drilling), and residential and industrial infrastructure (roads, transmission lines, railroads, and pipelines; table 2).</p>
