Restoration suitability index values were calculated for the inclusive OHSIM (4-RSI) and the salinity-only-based model (3-RSI, percent cultch value removed), as shown in Figure 9A and B, respectively.
1 % had medium to high suitability, and almost 5% had high suitability in the inclusive OHSIM (4-RSI) results.
The influence of percent cultch is also illustrated in Table 3, in which more than 70% of the study area had medium to high or high suitability in the salinity-only-based model 3-RSI results, decreasing to less than 10% area with medium to high or high suitability in the inclusive OHSIM 4-RSI results.
The OHSIM is a simplified version of the one developed by Soniat (2012).
Our results indicated that the OHSIM is highly sensitive to percent cultch.
To determine how robust the OHSIM was to data input, we applied it to 2 regions that had different data resources.
However, we were trying to determine how robust the OHSIM was when nonideal data were available.
The OHSIM represents a generalized model for determining locations suitable for oyster restoration throughout the Atlantic and Gulf coasts, and it provides a scientifically based support tool for natural resource managers and project planners.
