The action was prompted by a 2018 legal victory by the Center for Biological Diversity, Wishtoyo Foundation, and Turtle Island Restoration Network—which sued over the federal failure to designate critical habitat as required by the Endangered Species Act.
“Pacific humpbacks finally got the habitat protections they’ve needed for so long. Now we need to better protect humpbacks from ship strikes and entanglement in fishing gear, their leading causes of death,” said Catherine Kilduff, an attorney with the Center in a statement. “To recover West Coast populations of these playful, majestic whales, we need mandatory ship speed limits and conversion of California’s deadly trap fisheries to ropeless gear.”
The Center for Biological Diversity also sued the federal government in January for failing to protect endangered whales from speeding ships using California ports. The organization is also co-sponsoring the California Whale Entanglement Prevention Act (Assembly Bill 534), which would require the state’s commercial Dungeness crab and other trap fisheries to convert to ropeless gear (also known as “on-demand” or “pop-up buoy” gear) by the end of 2025.
One population of endangered humpback whales that feeds off California’s coast contains fewer than 800 individuals, leaving them vulnerable to threats from humans.
This rule is a win, as it designates a total of 224,030 square nautical miles for the two endangered and one threatened populations, but overlapping habitat means 116,098 square nautical miles will be protected.
Specifically, the rule designates 48,521 square nautical miles of critical habitat off the coast of California, Oregon, and Washington for the humpback population that winters in Central America.
The Mexico population got 116,098 square nautical miles in the North Pacific Ocean, including Bering Sea and Gulf of Alaska—regions that also made up the 59,411 square nautical miles listed for the Western North Pacific humpback population.
“Today is a good day for humpback whales and the ocean all living things depend on,” said Todd Steiner, executive director of Turtle Island Restoration Network. “Designating 116,000 square miles of critical habitat in the ocean is something to celebrate, but whales, turtles, and dolphins still need additional protection from industrial fishing and ship strikes to recover and thrive, so we won’t be resting on our laurels.”
Critical habitat protection will help safeguard ocean areas essential for migrating and feeding. The designation will ensure that federally permitted activities do not destroy or harm important whale habitat. Evidence shows that endangered or threatened species that have protected critical habitat are twice as likely to be recovering as those without it—and that’s good news indeed.
