In Alaskan kelp forest ecosystems, sea otters are the keystone species that mediates this trophic cascade. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead.
The rocky reef, kelp forest and emergent rock habitats in these MPAs support numerous species of invertebrates, plants, fish and marine mammals; among them are garibaldi, rockfish, octopus, gorgonians, nudibranchs, bat rays, kelp bass and many more.
Carmel Pinnacles State Marine Reserve (SMR) is a marine protected area in Carmel Bay including a unique underwater pinnacle formation with adjacent kelp forest, submarine canyon head, and surfgrass. [1] Carmel Bay is adjacent to the city of Carmel-by-the-Sea and is near Monterey, on California's central coast.
The islands are off the coast of Southern California, near Los Angeles, Ventura and Santa Barbara. ... Marine biologists with the National Park service monitor Channel Islands' kelp forest, which ...
Ecological habitats found in the sanctuary include extensive kelp forests, rocky reefs, deep-water coral gardens, sandy beaches, coastal dunes, and wetlands, the latter serving as nursery grounds for numerous commercial fish species and important habitats for many threatened and endangered species.

A welding hammer strapped to her wrist, Joy Hollenback slipped on blue fins and swam into the churning, chilly Pacific surf one fall morning to do her part to save Northern California's vanishing ...
The area is a hotbed of biodiversity and sustains a thriving ecosystem. The areas encompass four distinct habitat zones; rocky reef, kelp forest, sandy flat, and deepwater canyon. In a study focused around the benefits of MPAs, it was found that throughout the La Jolla region, there were half of the known California fish species present. [8]
Fish that live in and rely on kelp forests include kelp surfperch (Brachyistius frenatus), kelp bass (Paralabrax clathratus), giant kelpfish (Heterostichus rostratus), and kelp rockfish (Sebastes atrovirens). A study conducted near San Luis Obispo, California showed that when kelp was removed from a nearby reef, fish biomass declined by 63%.
