Since 1854, salt is one of San Francisco’s largest industries, with over 80% of its wetlands developed for salt mining. The salt ponds cover over 16,500 acres, most of which was owned by Cargill, Inc., an international food production and marketing company. In 2003, Cargill, Inc. sold 15,100 acres of the ponds to state and federal agencies, as well as private foundations, who are now in the process of restoring the land to its pristine tidal wetland beginnings.
