Description: This layer depicts the Gulf of Mexico Decision Support project Louisiana study area. State waters of Louisianai up to a 3 nautical mile boundary were mapped and used as the study area to generate the oyster restoration dashboard layers for Louisiana. <a href='xml/LA_Study_area.xml' target='_blank'><b>Metadata</b><a></br>
Description: Oysters are likely to be successful in areas where they historically have been productive. However, it is important to note that conditions may have changed in the given time span such that restoration may not be suitable in all of the areas identified by this layer. To identify areas where oysters have been or are currently found, multiple current and historic oyster reef data sets were collated and merged. Areas with reef were scored 1 and all remaining areas were scored a 0. The scored polygons were converted to a 500m, 500m grid. Original data source: TNC digitization (Vermilion Bay), 1920s Coast Line and Oyster Bottoms of Louisiana Historic Map digitization (TNC). Resolution: varies from 1:24,000 to 1:200,000.

Description: Oysters are able to thrive at a variety of depths, however, for the objectives of this project, the depth of placement was restricted to a maximum of 10 feet. All areas 10ft deep or less were scored 1 with remaining areas scored 0. The scored raster was resampled to a 500, 500m grid. Original data source: NOAA Bathymetry of Texas-Louisiana Continental Shelf and Coastal Regions (Digital Vector Data) compiled by Texas Parks and Wildlife Dept. (1930-2005).

Description: Optimal salinity zones (5-25ppt) were scored as most suitable for oyster restoration while areas of extreme low and high salinities were scored as least suitable. Polygons representing optimal salinities between 5-25 ppt were scored 1 with remaining areas scored 0. The scored polygons were converted to a 500m, 500m grid. Original data source: Salinity Zones in Estuaries along the Gulf of Mexico- NOAA/NCDDC (polygon), Resolution: 1:24,000. <a href='xml/LA_salinity_score.xml' target='_blank'><b>Metadata</b><a></br>
Description: Oyster reefs placed next to marshes help mitigate shoreline erosion in vulnerable areas along the coast. A polygon layer identifying all wetland areas in Louisiana was used to identify suitable areas 50 meters or less from marshes. Suitable areas were scored a 1 and all remaining areas were scored 0. Scored polygons were converted to a 500m, 500m grid. Original data source: USFWS National Wetland Inventory data (polygon). <a href='xml/LA_dist2mar.xml' target='_blank'><b>Metadata</b><a></br>
Description: Oyster restoration projects can provide social and economic benefits to those communities whose livelihoods depend most upon the health of coastal natural resources. To identify coastal communities with high levels of natural resource job dependence, we used census data to map the percentage of the workforce employed in agriculture, forestry, and fishing per census block group. Need one sentence on classification method. Nearshore areas (within 2km of shore) adjacent to block groups with high concentrations of workers employed in natural resource dependent sectors were scored 1 while areas adjacent to medium concentrations received a score of .5. All remaining areas were scored 0. Scored polygons were converted to a 500m, 500m grid. Original data source: 2000 US Census (polygon), Resolution: 1:100,000.

Description: Placement of reefs in areas where public and private oyster leases for harvesting are not present were considered most beneficial. All areas indicating public or private oyster leases were deemed unsuitable and scored a 0 while all other areas without leases were deemed suitable and scored a 1. Scored polygon data were converted to a 500m, 500m grid. Original data source: Louisiana Dept. of Wildlife and Fisheries (LDWF) 2001, LDWF 2006 (polygon).<a href='xml/LA_ppf.xml' target='_blank'><b>Metadata</b><a></br>
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.
