Like state and national parks protect wildlife and habitats on land, marine protected areas (MPAs) conserve and restore wildlife and habitats in our ocean. Under the California Marine Life Protection Act (MLPA) passed in 1999, California began a historic effort to establish a science-based, statewide network of MPAs through a collaborative effort that includes the California Department of Fish and Wildlife and California State Parks. California is taking a regional approach to the design and implementation of MPAs, and has divided the state into five regions: the north coast, south coast, north central coast, central coast and San Francisco Bay.
MPAs contribute to healthier, more resilient ocean ecosystems that can better withstand a wide range of impacts such as pollution and climate change. By protecting entire ecosystems rather than focusing on a single species, MPAs are powerful tools for conserving and restoring ocean biodiversity, and protecting cultural resources, while allowing certain activities such as marine recreation and research. There is a global body of scientific evidence about the effectiveness of marine protected areas and reserves to restore marine ecosystems (http://www.piscoweb.org).
In the waters adjacent to the William Randolph Hearst Memorial Beach there are two MPAs, Cambria State Marine Park (SMP) and White Rock (Cambria) State Marine Conservation Area (SMCA).
