A conservation organization has once again filed notice of its intent to sue the U.S Fish and Wildlife Service for “violations” to develop a national gray wolf recovery plan under the Endangered Species Act.

The lawsuit by the Center for Biological Diversity is in response to the Service’s November decision that protections under the Endangered Species Act for the gray wolf are “no longer appropriate,” therefore, writing a recovery plan would be a fruitless endeavor.

“We found that recovery plans would not promote the conservation of the gray wolf... [and are] no longer appropriate under 4(a)(1) of the Endangered Species Act,” according to a statement by the Fish and Wildlife Service.

Secretary of the Interior Doug Burgum and Fish and Wildlife Director Brian Nesvik (formerly the director of the Wyoming Game and Fish Department) are cited in the notice. A consequence of the Service’s findings is that recovery plans are “no longer statutorily required under the Act and the Service will not develop recovery plans,” they reported. The Center claims the Service is abandoning recovery efforts for the species.

“We’re challenging the Trump administration’s unlawful decision to once again abandon wolf recovery, and we’ll win,” said Collette Adkins, a senior attorney and the carnivore conservation director at the Center. “The Fish and Wildlife Service must live up to the reality of what science and the law demand. That means a comprehensive plan that addresses gray wolf recovery across the country.”

Previously, the Center sued the Biden administration, resulting in an agreement to publish a plan that would have been a central feature of its “long term and durable approach to the conservation of gray wolves.” That announcement stemmed from an agreement following a 2022 lawsuit in a District of Columbia federal court, ruling the U.S. Fish and Wildlife Service must draft a new recovery plan.

“The draft plan must be completed within two years unless the agency finds that such a plan will not promote the conservation of the species,” according to the results of the 2022 lawsuit.

“It neglects other places where wolves live and could recover, like the West Coast, southern Rocky Mountains and northeastern United States,” according to a statement made by the Center on Tuesday.

News of the new suit was met with concern by Sen. Cynthia Lummis, R-Wyo.

“For far too long, radical environmentalists have weaponized the Endangered Species Act to impose their will on Wyoming and the West,” she said in an email exchange with the Tribune. “Now that the Trump administration is taking action to return the ESA to its intended mission and rightfully return species management to states, environmental extremists like the Center of Biological Diversity are panicked and throwing Hail Marys as a last ditch effort to maintain their power, scientific evidence of recovery notwithstanding.”

A Game and Fish official said they can’t comment on the news of pending litigation. The department offers hunting licenses inside the trophy zone surrounding the state’s border with Yellowstone National Park. Gray wolves have a dual-classification management structure as defined in Wyoming state law. Wolves in northwest Wyoming’s Wolf Trophy Game Management Area (WTGMA) are classified as trophy game animals, and wolves outside this area are classified as predatory animals. A third management area in western Wyoming classifies wolves as predatory or trophy game animals depending on the time of year.

The gray wolf population in Wyoming usually exceeds 300 wolves annually, including around 100 wolves in Yellowstone National Park, according to the department. The department actively monitors wolf populations in Wyoming, primarily using telemetry collars. Organizing wolf populations into social packs that maintain exclusive territories allows Game and Fish to collar individual wolves in most packs, allowing the entire pack to be monitored throughout the year. As a result, the department can census, rather than estimate, the minimum number of wolves in the population annually. In addition to censusing numbers, the department monitors pack composition, reproduction, genetic integrity, and survival of pups and adults to determine the relative health of the population.

Large carnivore biologists also monitor wolf mortality by tracking collared wolves and mandatory reporting of all wolves harvested in the state, which informs assessment of the effectiveness of management actions and future management decisions, according to department literature.

In 2020, the first Trump administration removed all Endangered Species Act protections nationwide for gray wolves. A federal court vacated that rule in 2022 and restored the wolf’s federal protection in the lower 48 states, excluding wolves in the northern Rocky Mountain states of Wyoming, Montana and Idaho. The Fish and Wildlife Service’s appeal of that ruling remains pending before the Ninth U.S. Circuit Court of Appeals.

Wyoming regulations allowed 44 wolves to be harvested by hunters in 2024. This year, most hunt areas close Dec. 31, though one region remains open through March 31. Wolves classified as predatory animals can be harvested year-round without a license. Any wolf harvested in the predatory animal area must be reported to the department within 10 days of harvest, according to the department.

The Endangered Species Act requires parties submit a 60-day notice of intent to sue before a lawsuit can be filed. The Center said it intends to file its formal lawsuit in early February, seeking to include areas where wolf reintroductions are “in their infancy,” including in California and Colorado. Neither states have a federal plan to guide their recovery, the Center said.

The previous national recovery plan was written in 1992. Decades later there’s still no comprehensive plan that addresses gray wolf recovery across the country, the Center reported.

Although the gray wolf’s current Endangered Species Act protections do not extend to wolves in the northern Rocky Mountains, the Center and other conservation allies won a lawsuit this past August aimed at restoring federal protections to wolves in Idaho, Montana and Wyoming, along with portions of Washington, Oregon and Utah.

The U.S. Fish and Wildlife Service is appealing the ruling in the Ninth Circuit Court of Appeals, as are the State of Utah, the State of Montana and a trio of sportsmen’s groups. The appellees will lay out their specific objections to the lower court’s ruling in a series of upcoming briefs.

Fish and Wildlife’s opening brief is due to be filed with the Ninth Circuit by Christmas Eve. The lawsuit was brought by the Center, Humane World for Animals, the Humane World Action Fund and the Sierra Club.
