Defending Sea Otter Recovery in Southern California

What's at Stake

The population of California sea otters before fur traders arrived is believed to have been between 14,000 and 16,000. But in 2012, the animals’ three-year population average was only 2,792.

Their fondness for eating urchins and other invertebrates helps keep these populations in check, contributing to the health of kelp forests.

Case Overview

Conservation and wildlife groups, represented by Earthjustice, are defending a decision by the U.S. Fish and Wildlife Service to end a failed policy of trying to exclude sea otters from their Southern California habitat—a so-called “no-otter zone”—by relocating otters to other areas. An industry group, the California Sea Urchin Commission, has filed a lawsuit challenging the federal decision to end the counterproductive management policy.

In 1987, the U.S. Fish and Wildlife Service passed a regulation establishing a “no-otter zone” off the coast of Southern California as part of a plan to translocate sea otters to San Nicolas Island. At the time the agency suggested that the translocation program would help southern sea otters, which are protected as a “threatened” species under the Endangered Species Act, to gain protection should a catastrophic event like an oil spill threaten the otter population along parts of the California coast. The “no-otter” zone was established by Congress in response to complaints from fishermen that moving otters to a new location could interfere with their fishing activities.

The translocation program ultimately fell short of expectations because not enough otters remained at San Nicolas Island to establish a viable population. Many relocated otters swam back to their waters of origin; others died from being captured or transported. U.S. Fish and Wildlife Service subsequently determined that enforcing the no-otter zone would hurt sea otters’ protection and recovery. In 2013, the agency ended the “no otter zone” and translocation program in order to allow otters to expand to their natural, historical range south of Point Conception, which is necessary to achieve recovery of the species.

But that decision is being challenged by the California Sea Urchin Commission, an organization that represents urchin harvesters and views sea otters as competitors. While sea otters do enjoy urchins, they also eat clams, mussels, mollusks, crustaceans and snails. Also, their fondness for eating urchins and other invertebrates helps keep these populations in check and prevents them from mowing down kelp forest habitat.

The population of California sea otters before fur traders arrived is believed to have been between 14,000 and 16,000. But in 2012 the animals’ three-year population average was only 2,792.

The district court dismissed the suit on procedural grounds but the fishing groups have appealed that ruling to the Ninth Circuit Court of Appeals.

Groups Will Fight Industry Lawsuit Seeking to Eliminate Sea Otters From Southern CA

Conservation and wildlife groups will defend the U.S. Fish and Wildlife Service’s decision to end a failed sea otter translocation policy that relocated otters to San Nicolas Island and established a “no-otter zone” off the coast of Southern California. The program, which failed to establish a viable population around the island, also resulted in the death of countless sea otters that attempted to swim back to their waters of origin.
