Most U.S. Wolves are listed as Endangered—again. Here’s why.

A new court decision protects wolves, except in the Northern Rockies, just over a year after they were delisted. What’s next in the chaotic world of wolf conservation?

“Gray wolves in most of the United States are once again protected under the Endangered Species Act, according to a new legal decision.

A U.S. District Court judge in Oakland, California, ruled on February 10that the U.S. Fish and Wildlife Service acted improperly in delisting wolves. That decision, which went into effect in October 2020 toward the end of the Trump Administration, removed federal protections for the animals, arguing they had recovered within substantial parts of their range. This delisting decision has been upheld—and defended in court—by the Biden Administration.

The new ruling amounts to a thorough and sweeping rebuke of the wildlife agency’s policy on gray wolves, experts say. Conservationists, scientists, and even some hunters have cheered the decision, with something of an asterisk.

“It’s a good day for science, for wolves, for ecosystems, and for the people who value wolves,” says Adrian Treves, a wolf researcher and professor of environmental studies at the University of Wisconsin.

For instance, the court decision means that most forms of wolf-killing, such as hunting or trapping, will be illegal outside the Northern Rockies. This is most relevant for the Great Lakes states, including Wisconsin, which authorized a controversial wolf hunt in February 2021 that killed 218 wolves in under three days.

But owing to previous legislation that wasn’t at issue in the current lawsuit, the ruling does not apply to wolves in the Northern Rockies, which includes Idaho, Montana, most of Wyoming, as well as parts of eastern Washington, eastern Oregon, and northern Utah. Those animals will continue to be managed by the states and not the federal government. Moreover, in 2021, Idaho and Montana enacted laws to remove most restrictions on wolf hunting. Well over 500 wolves have been killed in these states alone since last spring, out of a total population of around 2,600, according to government figures. That’s just the official tally—the likely death toll is higher.

“We’re overjoyed at the national decision but … at the same time it only highlights what is only a deteriorating situation in the Northern Rockies, where three states have gone all out to reduce restriction and introduce new ways to kill wolves,” says Ben Scrimshaw, an associate attorney for Earthjustice, an environmental group.

Not everybody is pleased with the ruling, however. Some livestock associations, hunter organizations, and state wildlife management authorities expressed opposition, saying wolves have recovered in parts of the Northern Rockies and Great Lakes.

“Today’s decision conflicts with the intended purpose of the Act and removes critical management tools for wolves that pose a tremendous threat to farmers and ranchers, rural economies, and vital land and natural resource conservation,” says Kaitlynn Glover, with the National Cattlemen’s Beef Association, in a statement.

Vanessa Kauffman, a spokesperson for the Fish and Wildlife Service, says the agency is reviewing the court decision, but didn’t offer further comment or respond to other questions.

Here’s what the decision means more broadly for wolves—and what’s next.

Under the gun

Gray wolves, which once roamed most of North America, were widely hunted and intentionally exterminated by government officials; by the mid-1900s, the last population of wolves in the Lower 48 was confined to Minnesota. The animals have been protected under the Endangered Species Act since the 1970s, and their populations have grown in the Great Lakes region through natural expansion and recolonization from Canada; the same is true for the Northern Rockies, though wolves were also reintroduced to central Idaho and Yellowstone National Park in the mid-1990s.

Since then, wolf management in various regions has switched back and forth between the federal government and the states, making the situation complex and confusing even for professionals in the field. In 2011, Congress introduced legislation to delist gray wolves in most of the Northern Rockies; in 2017, the Fish and Wildlife Service did the same in Wyoming. The Trump Administration did the same in a decision announced in October 2020.

Several environmental and Native American groups sued the federal government challenging the Trump Administration’s delisting rule, arguing that it failed to uphold the Endangered Species Act in several ways. And the district court responsible for addressing the lawsuits, the Northern District of California, agreed. (Learn more: Is the gray wolf still endangered? Depends whom you ask.)

“They rejected all the arguments that the [wildlife] service used to abandon the wolf issue,” says Jamie Rappaport Clark, president and CEO of Defenders of Wildlife, one of the plaintiffs in the case. “It’s a pretty significant indictment of state management of wolves.”

Mexican gray wolves (a subspecies of gray wolf) and red wolves (a separate species) were not affected by October 2020 delisting decision, and remain endangered. (These rare wolves are unique species. Here’s why that matters.)

The court rejected several justifications that the wildlife service used to delist wolves, such as the argument that gray wolves don’t represent a “species” under the definition of the Endangered Species Act because they’re found throughout many other nations and not confined to the United States. And because the animals are absent from a “significant portion of their range,” the agency’s argument that they had recovered also rang hollow, the judge said. The court also concluded that the service was wrong not to consider threats to wolves outside their core populations in the Northern Rockies and Great Lakes, explains Dan MacNulty, a wolf researcher at Utah State University.”
