Description: Oysters are likely to be successful in areas where they historically have been productive. However, conditions may have changed in the given time span such that restoration may no longer be suitable in these areas. It’s also important to note that experts with local knowledge were less confident in the accuracy of the historical dataset. Therefore, this parameter was weighted as less important in determining oyster restoration suitability and areas within 1 mile of a historic reef were scored 2, while all other areas were scored 0. Data Sources: Historic Oyster Reefs digitized from maps - Lt. Francis E. Winslow (1887). <br><br> * Based on federal guidelines, areas located within 50 feet of either side of a navigation channel, within 150 ft of marinas, boat access points, or anchorage areas, or overlapping dredge disposal areas were excluded from this analysis. Areas beyond 1 mile from the shoreline have been excluded as they would not be suitable for subtidal shoreline oyster reefs.
