Washington, D.C.

Defenders of Wildlife and partner conservation groups filed an emergency rulemaking petition with NOAA Fisheries today to protect critically endangered North Atlantic right whales from being struck and killed by vessels in their calving grounds off the coast of the southeast United States.

“Right whales have journeyed to the Southeast since time immemorial to birth and nurse their calves in the safety of warm, shallow waters,” said Jane Davenport, senior attorney at Defenders of Wildlife. “But the calving grounds have become killing grounds. If we don’t protect vulnerable mother-calf pairs, we cannot protect this species’ future.”

The requested rule mirrors a NOAA Fisheries proposal to set speed limits for vessels 35 feet long and greater and expand the areas where speed limits apply. The agency has yet to finalize that proposal, and the emergency rule would help prevent incidents like the boat collision that killed a right whale calf off Florida last year and likely fatally injured its mother, who has not been seen since. That collision also resulted in a $1.2 million loss of the vessel. 

“Speeding ships can’t be allowed to kill mother right whales and their babies during this year’s calving season, so federal officials have to act quickly,” said Kristen Monsell, oceans legal director at the Center for Biological Diversity. “Endangered right whales need better protection from vessels now, or the species faces extinction. It’s up to the Fisheries Service to immediately implement more protective speed restrictions in the whales’ only known calving grounds.”

Vessel strikes are one of two primary threats to the species’ existence, along with entanglements in commercial fishing gear. Right whales begin giving birth to calves around mid-November and the season lasts until mid-April. Both females and calves in southeastern waters are especially vulnerable during that time. Current regulations are not sufficient to protect the whales, and changes proposed by the NOAA Fisheries in August seem unlikely to go into effect before this year’s calving season.   

Right whales birth and nurse their calves off the southeastern coast from Cape Fear, N.C., in the north to below Cape Canaveral, Fla., in the south. Pregnant females and mothers with nursing calves are especially at risk of vessel strikes because of how much time they spend near the water’s surface. Calving females are also the whales most critical to the species’ survival and recovery. Scientists know of no other calving grounds for the right whale. 

During the last calving season, a 54-foot boat struck both a newborn calf and its mother off St. Augustine, Fla. The collision killed the calf and seriously injured the mother, who hasn’t been seen since. 

“A newborn calf spends most of its first few months of its life on the surface with its mother,” said Erica Fuller, senior attorney at Conservation Law Foundation. “Given that these whales are tough to see under the best of circumstances, slowing boats down is the only way to prevent collisions like those that have killed whales, injured people and caused major vessel damage in the past.”   

Today’s petition comes after the NOAA Fisheries issued a proposed rule in August 2022 to expand the existing vessel speed rule to smaller vessels and more areas. The current rule requires vessels 65 feet in length and greater to slow to 10 knots or less to protect right whales in certain areas at certain times. The agency has noted that a rule expansion is essential to preventing the whale’s extinction. But the agency’s proposed rule does not appear to be on track to go into effect by the start of calving season, necessitating an interim solution. 

“Slowing down is the best way to reduce accidental collisions, which is why there are speed zones around schools,” said Regina Asmutis-Silvia, executive director of Whale and Dolphin Conservation. “Striking a whale not only put the whales at risk but also can cause serious damage to vessels and injure passengers. Slowing down can save lives while it also saves a species.” 

The conservation groups’ petition urges the NOAA Fisheries to immediately apply the agency’s own proposed rule in the right whale’s calving rounds. It asks the agency to expand the existing seasonal speed zone to include more waters in the calving grounds between Florida and North Carolina and to apply the rule to vessels 35 feet in length and greater. The petition also asks that the agency make dynamic speed zones mandatory in the calving grounds following several reports that vessels are not complying with voluntary measures.

Scientists at the New England Aquarium recently determined that only 340 North Atlantic right whales remain, with about 70 reproductive females. The population has continued to decline from previous years, and right whales only give birth every 3 years to 10 years. 

NOAA Fisheries has determined that, given the high mortality level and declining population, at least 50 calves would need to be born each year for several years to stem the decline and put the species on the road to recovery.

Biden Administration Restores Roadless Area Protections to Tongass National Forest

Today, the U.S. Department of Agriculture reinstated the national Roadless Area Conservation Rule in the Tongass National Forest in Southeast Alaska. The move restricts development on roughly 9.3 million acres in North America’s largest temperate rainforest.

Vessel Strikes to Blame for Series of Whale Deaths?

On a cold winter beach in New Jersey, onlookers huddled around a 30-foot dead humpback whale lying on the sand. This was one of more than a dozen whales that have washed up on beaches along the U.S. East Coast since the beginning of December 2022. Five of these whales washed up in New Jersey, two in New York and others on the coasts of states from Maine to Florida. A total of 178 humpback whales have washed up along East Coast beaches since 2016, leading the National Oceanic and Atmospheric Administration to declare an “unusual mortality event.” An investigation is underway.
