Habitat Protection Sought for World’s Largest Turtle, Endangered Leatherback, Off California and Oregon Coast


SAN FRANCISCO, CALIFORNIA, Sep. 29 -/E-Wire/– A coalition of environmental organizations formally petitioned the federal government on September 26th to designate critical habitat under the Endangered Species Act for the Pacific leatherback sea turtle, a species whose frequent and deadly encounters with longline and gillnet fishing gear meant to catch swordfish have put it on a steep slide toward extinction.

The last members of an ancient lineage that has outlived the dinosaurs, leatherbacks are ocean giants that grow to the size of a small car, dive half a mile deep, and migrate across the entire Pacific Ocean basin from their nesting grounds in New Guinea and Indonesia to feed in the rich waters off California and Oregon. Leatherbacks swim more than 6,000 miles within a single year – the largest geographic range of any living marine reptile and one of the longest known migrations for any species in the world.
Leatherbacks in the Pacific Ocean have declined by more than 90 percent over the past three decades, primarily as a result of drowning in industrial longline and gillnet fisheries aiming to catch swordfish, sharks, and tunas. Marine debris and loss of nesting beaches due to sea-level rise also threaten the species, predicted to go extinct within the next few decades.
“Leatherback sea turtles survived the asteroid that killed off the dinosaurs, but they are unlikely to survive our appetite for swordfish,” said Brendan Cummings, oceans program director at the Center for Biological Diversity. “If leatherbacks are to survive the coming decades, we must turn the waters off California and Oregon into a true sanctuary for these imperiled creatures. Designating critical habitat is a vital step toward that end.”
The petition from the Center for Biological Diversity, Oceana, and Turtle Island Restoration Network asks the National Marine Fisheries Service to designate as critical habitat an area of ocean spanning Big Sur, California to central Oregon. The proposed area, comprising roughly 200,000 square miles, is a food-rich upwelling region favored by many marine species, including the leatherback.
Areas designated as critical habitat must be managed for species recovery recent studies have shown that species with critical habitat are twice as likely to have improving population trends as species without it.
“Sea turtles have been able to survive for millions of years with only their shells for protection. To survive the challenges of today, however, they will need more than that – they need help from all of us,” said Ben Enticknap of Oceana. “We know when and where leatherbacks are along our coastlines, and we know what the threats are to them while they are here. Designating this important area as critical habitat will ensure that no activities occur along our shores that would push these ancient and extraordinary animals further toward extinction.”
The proposed critical habitat area is currently designated as the Pacific Leatherback Conservation Area by the National Marine Fisheries Service. It is closed to drift-gillnet fishing for swordfish during a three-month period during the summer and fall when leatherbacks gather here to feed on jellyfish. But the Fisheries Service has recently proposed to re-open the area to drift-gillnet and pelagic longline fishing.
“If we don’t want one of the ocean’s most inspiring species to go extinct on our watch, permanent habitat protection for the giant leatherback must be put into place. Right now, we’re continually having to fight another proposal to allow destructive fishing technologies inside the already designated Pacific Leatherback Conservation Area,” said Todd Steiner, biologist and executive director of Turtle Island Restoration Network.
The Endangered Species Act requires the National Marine Fisheries Service to respond to the petition within 90 days. Contact Info:
