Reason for SelectionResilience scores quantify a combination of landscape diversity and local connectedness, stratified by geophysical setting and ecoregion. These measures represent the number of microclimates available to species and the current state of the landscape. This builds on research from Anderson and Ferree (2010), who showed geophysical diversity and elevation range were associated with biodiversity in the Eastern United States. Resilience emphasizes diverse landscapes where species are likely to be able to move and adjust to changing conditions.Input Data<ul><li>The Nature Conservancy’s (TNC) combined terrestrial and coastal <a target='_blank' href='https://www.conservationgateway.org/ConservationPractices/ClimateChange/Pages/RCN-Downloads.aspx' rel='nofollow ugc noopener noreferrer'>resilient sites for the conterminous U.S.</a> in geodatabase format (<a target='_blank' href='https://tnc.app.box.com/s/iujcn7ru9a1vahxqojnesz9ibgu7e6x2' rel='nofollow ugc noopener noreferrer'>resilient_sites_national.zip</a>), accessed 12-3-2024</li><li><a target='_blank' href='https://secas-fws.hub.arcgis.com/maps/0b3e3940763a4e3aae7647b0fe4c31e4/about' rel='nofollow ugc noopener noreferrer'>Southeast Blueprint 2025 extent</a></li></ul>Mapping Steps<ul><li>Clip the TNC data to the bounding box around the Southeast Blueprint 2025 extent.</li><li>To extract the terrestrial component of the analysis, reclassify the “type_des” field to assign “Terrestrial Resilience” a value of 1 and everything else a value of NoData.</li><li>Reclassify the “CONUS_Legend” field into the final indicator values:<ul><li>11 Most resilient = 7</li><li>12 More resilient = 6</li><li>13 Slightly more resilient = 5</li><li>17 Average/median resilient (terrestrial or coastal) = 4</li><li>18 Slightly less resilient (terrestrial or coastal) = 3</li><li>19 Less resilient (terrestrial or coastal) = 2</li><li>20 Least resilient (terrestrial or coastal) = 1</li><li>91 Developed = 0</li></ul></li><li>As a final step, clip to the spatial extent of Southeast Blueprint 2025.</li></ul>Note: For more details on the mapping steps, code used to create this layer is available <a target='_blank' href='https://www.sciencebase.gov/catalog/file/get/68ba6308d4be021908ad78ae?name=Southeast_Blueprint_2025_Data_Download.zip' rel='nofollow ugc noopener noreferrer'>in the Southeast Blueprint 2025 Data Download</a> under > 6_Code.Final indicator valuesIndicator values are assigned as follows:7 = Most resilient6 = More resilient5 = Slightly more resilient4 = Average/median resilience3 = Slightly less resilient2 = Less resilient1 = Least resilient0 = DevelopedKnown Issues<ul><li>This indicator does not account for the occurrence and timing of disturbance processes, particularly fire. Without fire, resilient sites in many terrestrial ecosystems will not serve as biodiversity hotspots. This is particularly problematic in pine and prairie ecosystems in the Piedmont and Coastal Plain.</li></ul>Disclaimer: Comparing with Older Indicator VersionsThere are numerous problems with using Southeast Blueprint indicators for change analysis.
