This size was chosen to contain most (&gt; 99%) of the large fires, with fire sizes generally smaller than 250,000 acres, although the largest extreme event fires can span multiple firesheds. These boundaries were created by dividing up the landscape into regular-sized units that represent similar source levels of community exposure to wildfire risk.</span><b><br /></b></p><p><b>Purpose:</b></p><p>Section 2a1 of the June 2022 Secretary’s Memorandum 1077-004 on Climate Resilience and Carbon Stewardship of America’s National Forests and Grasslands directed the Forest Service to spatially identify risks to ecosystem values to inform decision making by updating the fireshed risk map to include additional ecosystem and equity layers. <br /></p><p><b>Overview:</b></p><p>This layer was designed to enable data exploration of the firesheds with NFS lands in the west in relation to various datasets identified by all the contributing 2a1 sub team members for the Western United States. This layer show shows fireshed name, fireshed ID, number of acres along with other social and environmental characteristics, summarized at the fireshed level. Use this layer to explore patterns and relationships on National Forest lands in the Western United States.</p></div>
