Negotiating ecology: Marine bioregions and the destruction of the Southern California Bight

Bioregional studies tend to focus on landscapes and associated cultural and biological diversity. This essay provides a general overview of the ecology of the Southern California Bight (SCB), which is the coastal marine bioregion of southern California. The bioregion is considered one of the most threatened ‘hot spots’ for biodiversity in the world. The SCB includes the Channel Islands National Marine Sanctuary, the Channel Islands National Park, and a designated ‘biosphere reserve’ of the United Nations Man and the Biosphere Program. The essay describes the destruction of southern California's coastal watersheds and wetlands, and provides a summary of the significant decline in ecological productivity of the marine bioregion. Despite the decline in general marine ecosystem integrity, there has been no large-scale planning effort that focuses on the entire coastal marine bioregion. With this in mind, the essay provides an overview of recent policy initiatives that call for the establishment of Marine Protected Areas or MPAs to protect marine ecosystems. Without a new institutional approach to the entire bioregion the future of the coastal marine ecosystems of the system is rather dim. With this in mind, the author recommends a number of institutional changes that support large-scale bioregional planning.
