Description: Oyster reefs can be placed adjacent to eroding shorelines to help attenuate waves and stabilize shorelines. To identify portions of the shoreline that are currently vulnerable to erosion, we used a portion of the USGS Coastal Vulnerability Index. We extracted shoreline erosion rates for Louisiana and reclassified the values into quartiles with scores of .25, .5, .75, and 1. A score of 1 indicates areas with the highest erosion rates and a score of .25 indicates areas of low erosion or accretion. The scores were then allocated to the nearshore areas (within 2km of shore) adjacent to the shoreline. All remaining areas were scored 0. Scored polygons were converted to a 500m, 500m grid. Original data source: USGS Coastal Vulnerability Index (Used erosion raw values, polyline), Resolution: 3 arc-minute grid cell.
