- Resilient Coastal Sites (Southeast Blueprint Indicator) [U.S. Fish and Wildlife Service]
- Description
- Reason for SelectionThe resilient coastal sites indicator seeks to capture features of salt marshes that are important for salt marsh species and ecosystem function both now and in the future. Many of these characteristics, like water quality and landform diversity, also serve as indicators of a site's potential future habitat quality once the salt marsh is fully inundated and transitions to a new estuarine or marine habitat.Input DataBase Blueprint 2022 extentSoutheast Blueprint 2023 extentThis indicator combines data from the following TNC projects:TNCResilientCoastalSitesforConservationintheSouthAtlanticTNCResilientCoastalSitesforConservationintheGulfTNC Resilient Coastal Sites for Conservation in the Northeast and Mid-AtlanticFrom the South Atlantic and Gulf Resilient Coastal Sites projects, we used:The "RESILB1stC" field of the "Tidal_Complex_Resilience_Score_SLR65" layers: Final resilience score within existing tidal complexes in a 6.5 ft of SLR scenario.The "RESILB1stC" field of the "Migration_Space" layers ending in _SLR15, _SLR30, _SLR40, and _SLR65: Final resilience score within the migration space associated with each tidal complex in 1.5, 3, 4, and 6.5 ft of SLR scenarios. Migration space consists of low-lying areas adjacent to current tidal complexes that may support future tidal habitats as current habitats migrate due to SLR.The "RESILB1stC" field of the "Additional_Migration_Space" layers ending in _SLR15, _SLR30, _SLR40, and _SLR65: Final resilience score within additional migration space units in 1.5, 3, 4, and 6.5 ft of SLR scenarios. Additional migration space units capture portions of the migration space that do not spatially intersect current tidal marshes but may provide additional landscape context.From the Northeast and Mid-Atlantic Resilient Coastal Sites projects, we used:The "RESILssBZ" field of the "slr06_stratified_resilience" layer: Final resilience score within existing tidal complexes in a 6 ft of SLR scenario.Mapping StepsTo capture the resilience of existing tidal complexes in the highest SLR scenario (6.5 ft for South Atlantic and Gulf of America, 6 for Northeast and Mid-Atlantic):Convert the South Atlantic and Gulf of America "Tidal_Complex_Resilience_Score_SLR65" layers from vector to a 30 m raster data using the "RESILB1stC" field.Convert the Northeast and Mid-Atlantic "slr06_stratified_resilience" layers from vector to a 30 m raster using the "RESILssBZ" field. Areas that overlapped with the South Atlantic were removed from this input.To capture the resilience of the migration space and additional migration space associated with each tidal complex across all SLR scenarios (1.5 ft, 3 ft, 4 ft, and 6.5 ft):Convert all of the South Atlantic and Gulf of America "Migration_Space" and "Additional_Migration_Space" layers for each SLR scenario (ending in _SLR15, _SLR30, _SLR40, and _SLR65) from vector to a 30 m raster using the "RESILB1stC" field. Note: The Northeast and Mid-Atlantic data does not provide resilience scores for migration space or additional migration space.To create a combined coastal resilience layer:Combine the coastal resilience layers produced in the previous steps using the Cell Statistics "MAX" function in ArcGIS. This creates a layer depicting the highest possible resilience score for each pixel from the above sea-levelrise layers.Clip to the spatial extent of Base Blueprint 2022.As a final step, clip to the spatial extent of Southeast Blueprint 2023.Note: For more details on the mapping steps, code used to create this layer is available in theSoutheast Blueprint Data Downloadunder > 6_Code.Final indicator valuesIndicator values are assigned as follows: 7 = Most resilient 6= More resilient 5 = Slightly more resilient 4 = Average/median resilience 3 = Slightly less resilient 2 = Less resilient 1 = Least resilientKnown IssuesResilience scores on some indigenous lands are still under review and are not included in this indicator.This indicator does not account for the occurrence and timing of disturbance processes, like prescribed fire, which impact resilience.Accretion rates were not incorporated into the marsh migration data.The source data from TNC assesses costal resilience and sea-level rise slightly differently in a portion of coastal Virginia that falls into the Northeast and Mid-Atlantic region, where TNC conducted its first coastal resilience assessment. In the Northeast and Mid-Atlantic, TNC data only assessed coastal resilience within the existing tidal complex and did not score migration space as it does in the Gulf and South Atlantic regions. Therefore, migration space along the North Virginia coast will appear as NoData.Also, TNC assessed sea-level rise in the Northeast and Mid-Atlantic region in 1 ft increments (ranging from 1-6 ft) as opposed to 1.5 ft increments (ranging from 1.5-6.5 ft) in the Gulf and South Atlantic regions. As a result, this indicator likely underestimates the extent of resilient areas in this portion of coastal Virginia.Because resilience was only assessed for tidal marsh and its migration space, there will be areas of NoData in the coastal zone. Places that do not receive a resilience score are urban areas or non-marsh habitat in the coastal zone, but outside of the migration space.Disclaimer: Comparing with Older Indicator VersionsThere are numerous problems with using Southeast Blueprint indicators for change analysis.
