These footprints delineate the presence of existing infrastructure associated with developed sites within Grizzly Bear Primary Conservation Areas at the time of the analysis. The analysis was completed by Lisa Landenburger USDA, in 2018, who used the “Convex Hull geoprocessing algorithm (XTools Pro v.17.2 extension inside ArcGIS v.10.5.1 software)” to generate the polygons based on roads within the developed areas, using specific parameters according to the type of developed area. For more information about the methods used see the Grizzly Bear Conservation Strategy for the Greater Yellowstone Ecosystem (in revision 2021).</span></span></p><p style='background-color:rgb(255, 255, 255); color:rgb(76, 76, 76); font-family:&quot;Segoe UI&quot;, Arial, sans-serif; font-size:13.3333px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0px 0px 6px; padding-bottom:1em; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'><span style='font-size:14px;'><span>In winter of 2026, a 200ft expansion to the existing boundaries was approved by senior park leadership. YELL GIS created this layer of updated boundary polygons by using the Buffer (Analysis Tool inside ArcGIS 3.5.6) with a distance of 200 International Ft on the original dataset. These boundaries will be presented to the Grizzly Bear Conserervation Strategy interagency working group.</span></span></p><p style='background-color:rgb(255, 255, 255); color:rgb(76, 76, 76); font-family:&quot;Segoe UI&quot;, Arial, sans-serif; font-size:13.3333px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0px 0px 6px; padding-bottom:1em; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'><a target='_blank' href='https://irma.nps.gov/DataStore/Reference/Profile/2310646' rel='nofollow ugc noopener noreferrer'>IRMA Data Store Reference</a></p><p style='background-color:rgb(255, 255, 255); color:rgb(76, 76, 76); font-family:&quot;Segoe UI&quot;, Arial, sans-serif; font-size:13.3333px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0px 0px 6px; padding-bottom:1em; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'><span style='background-color:rgb(255,255,255); color:rgb(74,74,74); font-family:&quot;Avenir Next&quot;; font-size:14px;'><span style='display:inline !important; float:none; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'>NPS Open Data Reference:</span></span><span style='background-color:rgb(255,255,255); color:rgb(74,74,74); font-family:&quot;Avenir Next&quot;; font-size:16px;'><span style='display:inline !important; float:none; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'> </span></span><a target='_blank' href='https://public-nps.opendata.arcgis.com/datasets/62e94b50edf94356bff1ea0c40c4fcff_0/explore?location=44.597014%2C-110.544875%2C9' rel='nofollow ugc noopener noreferrer'>YELL Grizzly Bear Conservation Areas 2026 | National Park Service</a></p>
