Timeline: Wolves in Danger | Earthjustice
The gray wolf is one of North America’s most iconic native predators. The wolf’s incredible comeback in the Northern Rockies is one of our country’s greatest wildlife success stories.
Explore the history of the Northern Rockies gray wolves, beginning in the 1930s when their numbers were decimated after years of persecution, through their successful reintroduction in the 1990s, to current day’s first legal wolf hunts in the Northern Rockies in nearly a century:What’s Happening Now
On Oct. 29, 2020, the Trump administration finalized a rule removing Endangered Species Act protections for all gray wolves in the lower-48 states except for a small population of Mexican gray wolves in Arizona and New Mexico. The U.S. Fish and Wildlife Service made its decision despite the fact that wolves are still functionally extinct in the vast majority of their former range across the continental U.S. (More details.)20TH CENTURY1933ARIZONA HISTORICAL SOCIETYJanuary catch of Forest Service hunter T.B.

ENDANGERED SPECIES ACT BECOMES LAW
The Endangered Species Act (ESA) is signed into law by President Nixon.
It prohibits the “taking,” without explicit permission, of species deemed to be in danger of going extinct.
“Taking,” in this instance, means killing, harassing, or damaging habitat necessary for the survival and recovery of the species. 1974RAY PAUNOVICH / BUSCH FILMS VIA NPSA “wolf-like” animal sighted in Hayden Valley, August 7/8, 1992.
WOLVES LISTED AS “ENDANGERED” UNDER ENDANGERED SPECIES ACT
As part of the first list of species to receive federal protections, gray wolves are listed as “endangered” under the ESA.
The designation applies to all remaining wolf populations in the lower-48 states. 1982
10(J) RULE ADDED TO ENDANGERED SPECIES ACT
The ESA is amended to include the 10(j) rule, allowing the Interior Department to classify reintroduced species as experimental and nonessential.
The change is a result of local concerns about reintroduction of species to their historical ranges. 1995DIANE PAPINEAU / NATIONAL PARK SERVICESchoolchildren at Yellowstone’s Roosevelt Arch welcome a truck transporting wolves, January 1995.
WOLF REINTRODUCTION BEGINS
The U.S. Fish & Wildlife Service (FWS) begins reintroducing gray wolves to central Idaho and Yellowstone.
Wolves are brought in from Canada.21ST CENTURYJuly 2000
STATUS CHANGE TO “THREATENED” PROPOSED
FWS proposes dropping “endangered” status for most wolves in the United States and reclassifying them as “threatened,” a designation under the ESA that carries milder protections than “endangered” status. 2003JIM PEACO / NATIONAL PARK SERVICEWolves howling at Little America Flats in Yellowstone, February 2003.
RECLASSIFIED AS “THREATENED”
FWS reclassifies most gray wolves in the lower-48 as “threatened.”
Work also begins to delist most gray wolves entirely. As a requirement for delisting, states with wolf populations must have laws and management plans to ensure continued survival of the species. 2004JIM PEACO / NATIONAL PARK SERVICEWolf on glacial erratic at Yellowstone’s Little America Flats, February 2, 2004.
STATE MANAGEMENT PLANS: IDAHO, MONTANA, WYOMING
FWS accepts Montana’s and Idaho’s proposed management plans for wolves but rejects Wyoming’s.
The State of Wyoming, livestock and hunting interests supported plans to manage wolves as “predators,” which would permit indiscriminate killing in nearly 90% of Wyoming. 2004
WYOMING FILES SUIT
The State of Wyoming and 28 Wyoming-based livestock and hunting groups file suit, challenging FWS’s rejection of the Wyoming management plan. November 2004

The Bush administration gives livestock owners in Montana and Idaho more power to kill wolves.
Under the new “10(j) rule,” livestock owners can kill wolves without a permit if wolves are chasing livestock.
The rule also says states can take action against wolves if it can be demonstrated they are the primary reason for decline among deer or elk populations.21ST CENTURYMarch 2005JIM PEACO / NATIONAL PARK SERVICEWolf watchers at Yellowstone’s Slough Creek, March 2005.
WYOMING LOSES IN DISTRICT COURT; APPEALS
Federal District Court Judge Alan B. Johnson tosses out the lawsuit filed by the State of Wyoming and livestock and hunting interests challenging FWS’s rejection of Wyoming’s management plan.
The case is ultimately appealed to the 10th Circuit. February 2006JIM PEACO / NATIONAL PARK SERVICEWolf near Blacktail Pond in Yellowstone, February 16, 2006.
NORTHERN ROCKIES DELISTING PLAN ANNOUNCED
FWS announces plans to remove gray wolves in the Northern Rockies (Idaho, Wyoming, Montana) from the Endangered Species List, but only if Wyoming adopts a state management plan that FWS deems appropriate.
Wyoming’s original plan, rejected by FWS, remains under review by the 10th Circuit Court of Appeals. April 2006JIM PEACO / NATIONAL PARK SERVICEWolf 470F of the Leopold Pack, near Blacktail Pond in Yellowstone.
WYOMING LOSES APPEAL
The 10th Circuit Court of Appeals rules the lawsuit filed by the State of Wyoming and livestock and hunting interests to compel approval of the state management plan is without merit.
The ruling affirms a decision made one year prior by District Court Judge Alan B. Johnson, as well as FWS’s initial decision to reject the plan. August 2006
WYOMING DELISTING PETITION REJECTED
After 12 months of study, FWS rejects a petition filed by the Governor of Wyoming and the State Game & Fish Commission asking that gray wolves in the Northern Rockies be removed from the Endangered Species List.
The rejection is based on the lack of an adequate state management plan in Wyoming. February 2007
NORTHERN ROCKIES DELISTING PROPOSED
NATIONAL PARK SERVICEWolves from the Druid Pack bed down in the snow.
FWS issues a proposed rule to delist Northern Rockies gray wolves from the endangered species list.
Wyoming has yet to propose a management plan since their initial one was rejected by the 10th Circuit Court of Appeals. Without a Wyoming plan, FWS intends to keep a significant portion of wolves in Wyoming on the endangered species list. December 2007
WYOMING PLAN APPROVED
In an about-face, FWS approves Wyoming’s state management plan.
The plan allows anyone to kill any wolf that wanders outside the northwest part of the state, including wolves that live most of the year in Yellowstone National Park and leave the park for periods in the winter in search of food. December 2007
APPROVAL OF WYOMING PLAN CHALLENGED
Earthjustice files comments challenging the approval of Wyoming’s new plan to allow unlimited wolf killing in nearly 90% of the state. January 2008
10(J) RULE UPDATE CHALLENGED

Earthjustice challenges the Bush administration 10(j) rule that would allow wolves in Idaho, Wyoming, and Montana to be indiscriminately killed, including through aerial hunting.
To start killing, states only need to demonstrate that wolves are one of the reasons for elk and deer populations that fail to meet state objectives. February 2008
NORTHERN ROCKIES DELISTING RULE PUBLISHED
The final rule for delisting of the Northern Rockies population of gray wolves from the Endangered Species List is published.
Delisting is scheduled to take place in late March 2008. March 2008

PROTECTIONS REINSTATED FOR NORTHERN ROCKIES WOLVES
In response to the Earthjustice lawsuit, a federal court reinstated ESA protections for gray wolves in the Northern Rockies, just in time to keep wolves safe from fall hunts that would have been implemented in Idaho, Montana, and Wyoming.
Since delisting, more than 100 wolves were killed. Fall hunts would have killed hundreds more. January 2009PETE SOUZA / WHITE HOUSE
BUSH MIDNIGHT REGULATION TO DELIST NORTHERN ROCKIES WOLVES

IDAHO AND MONTANA WOLF HUNT INJUNCTION SOUGHT
Earthjustice asks the federal district court reviewing the delisting challenge for an emergency injunction to halt pending fall wolf hunts in Idaho and Montana. Earthjustice sought—and won—a similar injunction the last time wolf hunts began. September 2009
WOLF HUNT TO CONTINUE
A federal district court issues an order finding that the delisting of wolves in the Northern Rockies was likely illegal, but declined to stop wolf hunts in Idaho and Montana.
The order comes a week after Idaho’s wolf hunting season opened on September 1. Montana is set to begin wolf hunting on September 15. March 31, 2010
WOLF HUNT SEASONS END
Idaho’s wolf hunt season ends, with the loss of more than 500 wolves due to human killing.
The hunt, along with Montana’s similar season, followed the April 2009 delisting of populations in those states under the federal ESA. August 5, 2010TRACY BROOKS / U.S. FISH & WILDLIFE SERVICEGray wolf, August 2010.
PROTECTIONS REINSTATED FOR IDAHO AND MONTANA WOLVES
Federal District Judge Donald Molloy restores ESA protections for wolves in Idaho and Montana, stating that the decision by FWS to remove protections in only two states is “a political solution that does not comply with the ESA.”
In his ruling, the judge affirmed that protections for the same population cannot differ by state. March 2011LARRY MCGAHEYWolf faces a snowstorm in Seney National Wildlife Refuge, January 2011.
U.S. FISH & WILDLIFE SERVICE SETTLEMENT
Of the 14 conservation groups that joined in the June 2009 lawsuit to protect wolves, not all agree to a settlement with the U.S. Fish & Wildlife Service. This requires Earthjustice to withdraw as the clients’ counsel. April 15, 2011
“2009 RULE” REISSUED
President Obama signs into law the “Department of Defense and Full-Year Continuing Appropriations Act” for fiscal year 2011.

WOLF HUNTS IN IDAHO AND MONTANA
The 2011–2012 Montana wolf hunting and Idaho wolf hunting and trapping seasons begin, during which 166 wolves are killed in Montana, and 379 wolves are killed in Idaho. October 5, 2011
WYOMING DELISTING PROPOSED
FWS proposed a rule to remove the gray wolf in Wyoming from the endangered species list, claiming Wyoming’s wolf population is stable, threats will be addressed, and Wyoming’s wolf management laws are adequate.
This is notwithstanding FWS’s own peer review of the Wyoming delisting proposal, which concluded that “there is substantial risk to the population” because “the Plan, as written, does not do an adequate job of explaining how wolf populations will be maintained, and how recovery will be maintained.” March 14, 2012U.S. FISH & WILDLIFE SERVICEWolf in Necedah National Wildlife Refuge, January 12, 2012.
APPEALS COURT UPHOLDS MONTANA, IDAHO DELISTING
The 9th Circuit Court of Appeals ruled that Congress had the right to strip protections from wolves in Montana and Idaho in April 2011. August 31, 2012
WOLVES DELISTED IN WYOMING
FWS announced it is eliminating federal protections for Wyoming’s wolves, handing wolf management over to Wyoming, which will open almost all of the state to immediate, unconditional wolf killing.
Wyoming’s wolf population is estimated to be only 328 wolves, far fewer than either Idaho or Montana. November 14, 2012
WYOMING’S KILL-AT-WILL WOLF POLICY CHALLENGED
Following the required 60-day notice of intent to sue, Earthjustice filed suit on behalf of conservation groups, challenging the federal government’s elimination of ESA protections for wolves in Wyoming.
The state policies will result in wolf deaths that undermine the recovery of the species. May 9, 2013
INTERIOR DEPARTMENT URGED NOT TO DELIST WOLVES IN LOWER-48
KEITH SHANNON / U.S. FISH & WILDLIFE SERVICESecretary of the Interior Sally Jewell.
Six of the nation’s most prominent conservation groups called on Interior Secretary Sally Jewell to cancel plans by FWS to remove federal ESA protections for wolves across nearly the entire lower-48 states.
The letter is signed by the chief executives of the Center for Biological Diversity, Defenders of Wildlife, Earthjustice, Endangered Species Coalition, Natural Resources Defense Council and Sierra Club. June 7, 2013
LOWER-48 WOLF DELISTING PROPOSED
FWS proposed removing federal Endangered Species Act protections for wolves across nearly the entire lower-48 states, except for a small population of Mexican wolves in Arizona and New Mexico, where only about 75 wild wolves remain.
The plan would be disastrous for gray wolf recovery in the United States. December 17, 2013
PUBLIC VOICES SUPPORT FOR PROTECTIONS FOR WOLVES

In a public comment period, approximately one million Americans stood in opposition to the proposal to strip endangered species protections from gray wolves across most of the lower-48.
It is one of the largest numbers of comments ever submitted on a federal decision involving endangered species. February 2014
SCIENTIFIC PEER REVIEW QUESTIONS NATIONAL WOLF DELISTING PROPOSAL
An independent scientific peer review unanimously concluded that the FWS’s national wolf delisting rule did not currently represent the “best available science.”

WOLVES RETAIN PROTECTIONS IN WYOMING & GREAT LAKES STATES
Wolves in Wyoming, Michigan, Minnesota and Wisconsin will retain their federal protections after a contentious policy “rider” that would have stripped them of Endangered Species Act protections was excluded from the final omnibus government spending bill.
The rider would have overridden two federal court decisions (including the September 2014 victory for wolves in Wyoming) that found those states’ management plans do not sufficiently protect wolves, while also barring further judicial review of the court decision overrides. January 7, 2016
CONSERVATIONISTS CHALLENGE HELICOPTER INTRUSIONS IN PREMIERE WILDERNESS AREA
A coalition of conservationists, represented by Earthjustice, today filed a legal challenge to the decision by the U.S. Forest Service to allow the Idaho Department of Fish and Game to conduct approximately 120 helicopter landings in the Frank Church-River of No Return Wilderness as part of a program to manipulate wildlife populations in the wilderness. January 13, 2016
IDAHO BREAKS AGREEMENT USING HELICOPTER DROPS TO COLLAR WOLVES IN FRANK CHURCH WILDERNESS
The Idaho Fish & Game Department admitted that it broke an agreement with the U.S. Forest Service and used helicopter landings to collar wolves in the Frank Church River Of No Return Wilderness. This followed less than a week after Earthjustice filed its legal challenge. January 19, 2017
COURT RULES FOREST SERVICE ILLEGALLY AUTHORIZED HELICOPTER INTRUSIONS IN PREMIERE WILDERNESS AREA
The ruling by U.S. District Court Judge B. Lynn Winmill concluded that the Forest Service violated the Wilderness Act and conducted insufficient environmental review in allowing IDFG to land helicopters in the River of No Return in January 2016 to capture and place radio telemetry collars on wild elk. IDFG also captured and radio-collared four wolves during these operations—an unauthorized action that was not permitted by the Forest Service, but that threatened to advance IDFG’s plans to undertake widespread wolf-killing in the wilderness by providing locational information on the collared wolves. March 7, 2017
D.C. CIRCUIT COURT OF APPEALS RULING STRIPS ENDANGERED SPECIES ACT PROTECTIONS FROM WYOMING WOLVES
A three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit issued a ruling in Defenders of Wildlife, et al. v. Zinke, et al., reversing a district court decision that had restored Endangered Species Act protections for gray wolves in Wyoming. April 25, 2017
