The State of San Francisco Bay 2011 presents a science-based assessment of the health of San Francisco Bay. The authors reviewed available data and developed methods for evaluating the status and trends of the Bay’s vital signs. By providing all interested parties with these results, the broader community can consider whether resource managers, regulators, and citizens are taking enough of the right actions to protect the Bay. With this assessment, the Estuary Partnership will begin to report on the state of the Bay approximately every five years, with the goal of educating the public and helping scientists and managers make decisions about how to best allocate resources to protect and restore the Bay. The report can be downloaded by section or in its entirety using the links below.
