Strategic Goal 3: Enhance coastal and marine biodiversity

Through our biodiversity program, we work to enhance the diversity and health of California’s coastal and marine ecosystems, restore and protect threatened habitats, and support sustainable fishing through science-based, collaborative management. For example, our state’s unique and globally significant network of 124 marine protected areas (MPAs) is breaking new ground in improving ocean health. Supporting climate-resilient fisheries will protect marine ecosystems, local communities, and coastal economies. Additionally, coastal and marine biodiversity depend on clean water. Plastic pollution, harmful algal blooms, nutrient runoff, legacy and emerging pollutants, and marine invasive species harm ecosystems and individual species, plus trigger significant health and economic costs for Californians, including costs related to litter cleanup, contaminated beaches, and fisheries closures. Learn more in our Strategic Plan to Protect California’s Coast and Ocean 2020–2025.

Current Programs

We work to safeguard our coastal and underwater ecosystems, habitats, fisheries, and marine life by supporting the adaptive management of marine protected areas, supporting sustainable fisheries, fighting for water quality, and advancing California’s commitment to conserve 30% of our coastal waters by 2030.
