- California Ecosystems and Species
KELP FOREST RESEARCH IN CALIFORNIA
Much of California's iconic kelp forests have been lost due to the "perfect storm" of factors. California Sea Grant funded researchers are working to understand why and how to best restore these important habitats.
FAQ: California's Marine Heatwaves
Several marine heatwave events have taken place since 2014 off the coast of California. What is a marine heatwave? What drives these warming events? How do they impact marine life in the region? Learn more here.
FAQ: DROUGHT & CALIFORNIA'S COASTAL REGION
What is a drought, what causes them, and what are their effects on California? Explore this FAQ to learn more about what’s causing droughts and their impacts on California’s coastal regions.
RESTORING ENDANGERED SALMON
Learn how California Sea Grant is helping bring back endangered coho salmon in Sonoma County. If you like to go fishing, learn how to tell the difference between endangered coho and other species, to avoid heavy fines.
Non-native species can wreak havoc in lakes, rivers, and the ocean. Help protect kelp beds and reefs from invasive seaweeds, or check out our manual for lake managers on early detection monitoring for quagga mussels and rapid response to suspected invasions.
MARINE PROTECTED AREAS
California is home to a unique network of 124 marine protected areas (MPAs), created to protect our valuable ocean resources. This network was established through a science-based, stakeholder-driven process and represents one of the most advanced marine protection management systems in the world. California Sea Grant works with California state agencies to provide science-based information to help manage these important regions. Learn about MPA research and monitoring, find reports and data, and explore MPA outreach resources.
ESTUARIES: CONNECTING LAND TO OCEAN
Estuaries, one primary example of a coastal wetland, are transition zones between the land and sea where saltwater from the ocean mixes with freshwater from upland rivers, streams, hillsides and canyon runoff.
