Just as parks on land protect special lands and wildlife from over development and hunting, these underwater parks preserve California's stunning marine ecosystems for future generations to observe and enjoy.
California's coast and ocean are among our most treasured resources. The productivity, wildness, and beauty found here is central to California's identity, heritage, and economy.
The need to safeguard the long-term health of California's marine life was recognized by the California Legislature in 1999 with the passage of the Marine Life Protection Act. This Act aims to protect California’s marine natural heritage through establishing a statewide network of marine protected areas (MPAs) designed, created, and managed using sound science and stakeholder input.
MPAs protect the diversity and abundance of marine life, the habitats they depend on, and the integrity of marine ecosystems. The Marine Life Protection Act recognizes that a combination of MPAs (marine reserves, conservation areas, and parks) with varied amounts of allowed activities and protections can help conserve biological diversity, provide a sanctuary for marine life, and enhance recreational and educational opportunities. MPAs can also provide scientific reference points to assist with resource management decisions, and protect a variety of marine habitats, communities, and ecosystems for their economic and intrinsic value, for generations
Our Marin MPA Watch volunteers help to protect our MPAs in California by learning about the coastal environment, becoming "community scientists" and coastal stewards, and collect monitoring data on human uses to inform management decisions that would not be possible under the current state budget.
Marin County is home to nine (9) California MPAs and two (2) State Marine Parks along our coastline and within San Francisco Bay.
