Book Description
When Drakes Estero, which lies within the Point Reyes National Seashore (PRNS) about 25 miles northwest of San Francisco, California, was designated by Congress in 1976 as Potential Wilderness, it contained a commercial shellfish mariculture operation. Oyster mariculture began in Drakes Estero with the introduction of the nonnative Pacific oyster in 1932, and has been conducted continuously from that date forward. Hence, the cultural history of oyster farming predates the designation of Point Reyes as a National Seashore in 1962. Nevertheless, with the approach of the 2012 expiration date of the current National Park Service (NPS) Reservation of Use and Occupancy (RUO) and Special Use Permit (SUP) that allows Drakes Bay Oyster Company (DBOC) to operate within the estero, NPS has expressed concern over the scope and intensity of impacts of the shellfish culture operations on the estero's ecosystem. Public debate over whether scientific information justifies closing the oyster farm led to the request for this study to help clarify the scientific issues raised with regard to the shellfish mariculture activities in Drakes Estero.

Book Description
On September 13, 2012, Point Reyes National Seashore near San Francisco turned fifty. Mixing wilderness, history, and agriculture, Point Reyes is a hybrid park unlike any other in America. An Island in Time traces the triumph of its creation, the rescue effort that saved it from early abandonment, and its frequent identity crises since. Sixty images by regional photographers make it clear why people care. Celebrating what has been accomplished in half a century at Point Reyes, Hart takes a clear-eyed look at the several (and ongoing) arguments about what this remarkable piece of land should ultimately be. The nationally noted debate about the fate of a historic oyster farm within the park takes its place as the latest in a series of struggles to define the terms. In 1962, Harold Gilliam's classic book Island in Time: The Point Reyes Peninsula helped complete the drive to create the National Seashore. In 2012, An Island in Time: 50 Years of Point Reyes National Seashore tells the rest of the story-and illuminates the choices now at hand.

Book Description
It all began simply enough. In 1976 the Point Reyes Wilderness Act granted the highest protection in America to more than 33,000 acres of California forest, grassland and shoreline – including Drakes Estero, an estuary of stunning beauty. Inside was a small, family–run oyster farm first established in the 1930s. A local rancher bought the business in 2005, renaming it The Drakes Bay Oyster Company. When the National Park Service informed him that the 40–year lease would not be renewed past 2012, he vowed to keep the farm in business even if it meant taking his fight all the way to the Supreme Court. Environmentalists, national politicians, scientists, and the Department of the Interior all joined a protracted battle for the estuary that had the power to influence the future of wilderness for decades to come. Were the oyster farmers environmental criminals, or victims of government fraud? Fought against a backdrop of fear of government corruption and the looming specter of climate change, the battle struck a national nerve, pitting nature against agriculture and science against politics, as it sought to determine who belonged and who didn't belong, and what it means to be wild.

Book Description
U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.
