Summary
The Sarasota County Oyster Monitoring Program was designed to examine the role of Crassostrea virginica (Eastern Oyster) as an environmental indicator of watershed health. In the fall of 2003, Sarasota County began monitoring C. virginica in the Dona and Roberts Bay (DARB) watershed to determine the impacts of freshwater flows from Cow Pen Slough and the Myakka River/Blackburn Canal. Sites were chosen in Shakett and Curry Creeks, and Lyons, Dona, and Roberts Bays. In addition to the oyster data, rainfall, salinity, and discharge flow data, where available, were collected and used in the analyses. Staff was able to establish a link between declines in the percentage of live oysters and increased freshwater input in those sites receiving high freshwater in-flows. In the fall of 2006, the program was expanded to include sites in other coastal watersheds: Sarasota Bay Watershed (Hudson Bayou and Phillippi Creek); Little Sarasota Bay Watershed (Matheny, North, Catfish, and South Creeks); and Lemon Bay Watershed (Alligator, Forked, Gottfried, and Ainger Creeks). The expanded monitoring program provides comprehensive data for the entire county that can be used to track watershed health, evaluate the success of watershed management projects, and track the overall success of the county's comprehensive watershed management practices.

Notes
Application
To track watershed health, evaluate the success of watershed management projects, and track the overall success of the county's comprehensive watershed management practices.
