Areas Suitable for Oyster Restoration
2023-08-30T00:00:00
Identify areas within Mobjack Bay that are suitable oyster habitat based on four criteria: salinity, substrate, depth, and wave energy.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Geospatial layers were collected for each of the four habitat suitability factors identified as important for oyster growth and survival: salinity, substrate, wave energy, and bathymetry. Each layer was clipped and projected onto 1-meter grid cell covering the Mobjack Bay study area. Each grid cell contains a score value for each layer. Scores for the salinity and substrate layers were assigned so that unsuitable sites were excluded from the analysis. Scores for wave energy and bathymetry were assigned based on threshold values that affect the type of oyster structure suitable for that location. The suitability of each 1-meter cell was calculated by multiplying the scores for each of the four suitability layers, and the resulting overall score indicates whether the location is 1) suitable and 2) what type of oyster structure would be most appropriate based on bathymetry and wave energy. Suitable cells were exported to polygons, and areas with important management considerations (SAV beds, private lease areas, and Baylor grounds) are flagged.</SPAN></P></DIV></DIV></DIV>
