Shoreline Management Model v.6; Module 8: Oyster Structures
Module 8 identifies areas that may be suitable for oyster living shoreline structures based on site salinity, substrate, wave energy, and bathymetry.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Geospatial layers were collected for 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 locality. 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>

The annual SAV aerial photographic monitoring program provides a comprehensive and accurate measure of change in SAV relative abundance that has been used to link improving water quality to increases in bay living resources.
Wave Energy: Derived from two inputs: 1) Maximum fetch calculated in the SMM, and 2) wave energy outputs generated by CCRM's SCHISM model.

Oyster structure to consideration for generating shellfish habitat co-benefits
CCRM
Oyster Shell Bags
Oyster shells contained in a netting that bundles the shells together to reduce settling, scattering, and siltation of the shell reef. These are often placed or stacked along the leading marsh edge. Bagged oyster shells promote recruitment by serving as substrate for larval attachment and growth.
CCRM
Constructed Oyster Reefs (a,b,c)
Designed and built structures made of oyster shells or other suitable materials, suitable for the wave energy regime of the area. These constructed oyster reefs are classified into a) oyster shell bags, b) manufactured oyster reefs (examples include: oyster reef balls, Grow Oyster Reefs, Natrx), and c) stone reefs.
