The Bay Institute
The Bay Institute is a nonprofit research, education, and advocacy organization dedicated to protecting and restoring the ecosystem of the San Francisco Bay, the Sacramento-San Joaquin Delta, and the estuary's tributary rivers, streams, and watersheds. Created in 1981, TBI's scientific experts have worked to secure stronger protections for endangered species and their habitats; improve water quality; reform how California manages its water resources; and promote comprehensive ecological restoration from the Sierra to the sea. They are based in Novato, California. Aquarium of the Bay in San Francisco is affiliated with them.
