Along the West Coast of North America, Reef Check helps ensure the long-term sustainability and health of the nearshore rocky reefs and kelp forests. Reef Check volunteer citizen scientists are divers that come from a wide range backgrounds and who take a proactive role in making sure that our nearshore ecosystems are healthy and well managed. We train scuba divers to be citizen scientists familiar with local marine life and how to survey kelp forests. We provide them with the skills to conduct scientific surveys and then lead them in monitoring kelp forests along the West Coast.

The Garibaldi (Hypsypops rubicundrus) is California’s state marine fish. These fish make nests and after the female lays her eggs, the male Garibaldi will guard the nest from anyone who ventures near.

The California Coast

We monitor kelp forests inside and outside of California’s marine protected areas (MPAs) and Oregon’s Marine Reserves. We work with marine managers, researchers, and the public to provide scientific data needed to make informed, science-based decisions for the sustainable management, conservation and restoration of these critical habitats.

Our climate change project tracks ocean temperature at 75 of our monitoring sites. We aim to use this information from sentinel sites to begin to understand the effects of climate change on ocean life and how to mitigate them.

Through our kelp forest restoration program, we conduct restoration research and establish restoration sites across the West Coast. We are involved in various restoration projects in California, Oregon, and Washington. This work is testing different methods of purple sea urchin suppression, in conjunction with kelp enhancement and monitoring studies of kelp recovery. All restoration work is community focused to not only provide ecological benefits, but also economic benefit to the local ocean communities.

The sunflower star (Pycnopodia helianthoides) is typically found from Central California all the way north to Alaska. They can grow up to three feet wide and have lots and lots of arms. Unfortunately, the sunflower star has almost disappeared due to a disease that affected many sea stars along the Eastern Pacific Coast, including California.

Black Rockfish (Sebastes melanops) live in the northeast Pacific and are often seen in California. They can live to be 50 years old and can grow to be almost two feet long!
