The California Fish and Game Commission voted yesterday to list leatherback sea turtles as endangered protecting them under the state’s Endangered Species Act. The commission acted on the recommendation of the California Department of Fish and Wildlife, which is concerned by the turtles’ dramatic decline in state waters.
“California’s action will make an outsized difference for leatherback sea turtles, even in the face of global threats like the loss of nesting beaches,” said Catherine Kilduff, an attorney at the Center for Biological Diversity, in a statement.“Protecting the state’s ocean to save leatherbacks benefits not only sea turtles, but whales and people too. The California Endangered Species Act will ensure that leatherbacks’ decline gets the attention it deserves during this global biodiversity crisis.”
”For millions of years, leatherbacks have travelled across the Pacific using their long flippers, which can easily catch on fishing lines,” continued Kilduff. “Now California has to commit to ensuring they survive by converting to ropeless pots and traps and doing research to prevent entanglement in other gear.”
Scientists estimate that leatherback sea turtles have declined in abundance off the coast of California by 5.6%annually over nearly 30 years. An estimated 50 Pacific leatherbacksnow forage in California waters annually, as compared to 178 Pacific leatherbacks during the years 1990-2003.Whale-watching trips observed three leatherback sea turtles in August 2020 in Monterey Bay.
“California’s action today is a decisive step in the recovery of critically endangered leatherback turtles, one of California’s most giant, gentle, and unique marine species,” said Todd Steiner, a wildlife ecologist and Executive Director of Turtle Island Restoration Network. “Combined with earlier action to declare the leatherback the official marine reptile of California, we now must redouble our efforts to eliminate all threats from commercial fishing, pollution, and climate change.”
Protecting leatherbacks under the California Endangered Species Actwould make them a state conservation priority. Despite the lack of regular monitoring of state fisheries, leatherback sea turtles have been found tangled in commercial rock crab and Dungeness crab gear.
In June 2020 the California Department of Fish and Wildlife determined that increased protections may be warranted and began the status review. The action came in response to a petition from the Center for Biological Diversity and Turtle Island Restoration Network.
A review of leatherback sea turtle science last year concluded that West Pacific leatherbacks, one of seven distinct populations of leatherback sea turtles worldwide, face a high extinction risk. The National Marine Fisheries Service and U.S. Fish and Wildlife Service found that all seven leatherback sea turtle populations remain endangered and denied a petition by the commercial fishing industry to relax some protections.
The Center and TIRN sued the Trump administration after a fishing permit issued in 2019 exempted vessels from the federal ban on longline gear off the coast of California. Longlines stretch up to 60 miles, with thousands of baited hooks. A federal judge in Oakland, California, ruled that the federal government had failed to adequately consider impacts on leatherbacks when it revived longline fishing, blocking the permit.
