January 2005 – The Center participated in a successful coalition lawsuit overturning a Service wolf reclassification rule that downlisted wolves to threatened, divided gray wolves into distinct population segments, and precipitated a recovery-planning process that would have established Mexican gray wolves outside their historic range instead of where they evolved.
January 2005 – A federal judge dismissed a second case by the livestock industry, in which the Center served as an intervenor-defendant. The livestock industry was again seeking removal of all wolves from the wild.

August 7, 2007 – Following the Center’s 2006 lawsuit, the Service initiated a process to change the rules for management of the wolf reintroduction program. A draft Environmental Impact Statement was expected to be issued in spring 2008.
May 1, 2008 – The Center and allies sued the Service for its decision to put wolf reintroduction in the hands of agencies that have allowed wolf killings to rise, as well as for approving SOP 13.
May 16, 2008 – After the government-appointed wolf-management team refused to end SOP 13, a policy requiring all wolves with a certain depredation record to be “removed" — despite the request of New Mexico Governor Bill Richardson and the recommendations of numerous scientists — the Center wrote a letter to the team requesting a cessation of government wolf removals.
September 23, 2008 – Eastern Arizona’s Apache-Sitgreaves National Forest, key Mexican gray wolf habitat, proposed a new policy requiring livestock owners to dispose of their own animals’ carcasses when those animals died from causes unrelated to wolves. This measure would help prevent endangered wolves from becoming habituated to preying on livestock rather than their natural prey. The Center requested that the policy be applied not just in the Apache National Forest portion of the Blue Wolf Range Recovery Area, but also on all lands governed by the Apache-Sitgreaves National Forest’s Revised Forest Plan.
December 3, 2008 – The Center petitioned the Fish and Wildlife Service to update the Mexican gray wolf’s ancient recovery plan, published in 1982 and never revised.
December 22, 2008 – The Center and 16 other organizations asked the Service to replace the photograph of the Mexican gray wolf program’s “poster wolf” — prominently displayed on the agency’s Web site and at its Washington, D.C. headquarters — because the wolf was trapped and inadvertently killed in 2005.
February 6, 2009 – The U.S. Fish and Wildlife Service announced there were only two breeding pairs of Mexican gray wolves in the wild at the end of 2008 — a decline from just three breeding pairs at the end of 2007. The low number resulted from federal trapping and shooting of 19 wolves in 2007, including reproductively successful pairs.
March 10, 2009 – The Center and allies submitted comments on a Fish and Wildlife Service draft “conservation assessment” analyzing the current Mexican gray wolf management program. We called for development of a new Mexican wolf recovery plan to replace the outdated 1982 plan, as well as for a temporary cessation of removals of Mexican wolves from the wild.
March 25, 2009 – In passing the Omnibus Public Land Management Act of 2009, Congress approved a demonstration project involving federal compensation for livestock losses to wolves, as well as federal funding for nonlethal activities to reduce the risk of livestock losses to wolves.
August 11, 2009 – The Center petitioned the U.S. Fish and Wildlife Service to formally separate the Mexican gray wolf from other U.S. wolf populations and list it under the Endangered Species Act as either an endangered subspecies or a “distinct population segment.” On the same day, ending a Center lawsuit, a court ordered USDA Wildlife Services to release records detailing where Mexican wolves killed livestock prior to the agency shooting and trapping them.
November 13, 2009 – In response to Center litigation, the Fish and Wildlife Service reclaimed its decision-making authority over wolf management from a multiagency group hostile to wolf recovery, as well as scrapping the wolf-killing rule SOP 13.

September 30, 2010 – The Center condemned four newly introduced bills that would strip Endangered Species Act protections from wolves around the country before full recovery.
October 4, 2010 – The Center submitted comments on the Service's August finding.

February 1, 2011 – Livestock growers and two counties — plaintiffs in a lawsuit that asked the federal government to remove Mexican gray wolves from the wild in New Mexico — filed a motion seeking voluntary dismissal of their suit without prejudice (meaning that they could refile a similar suit later).
February 2, 2011 – A new census by federal and state agencies revealed that 50 Mexican gray wolves, including two breeding pairs, were counted in the wilds of New Mexico and Arizona at the end of 2010. The 50 wolves were eight more than the 42 wolves found at the end of 2009, representing the first increase in numbers in four years.
June 9, 2011 – New Mexico Gov. Susana Martinez’s state game commission voted unanimously to stop cooperating with the U.S. Fish and Wildlife Service in reintroducing the endangered Mexican gray wolf.

March 29, 2012 – On the 14th anniversary of the first reintroduction of endangered Mexican gray wolves to the wild in the Southwest, 30 conservation organizations, scientists, and animal-protection and sportsmen groups (including the Center) urged Interior Secretary Ken Salazar to release Mexican wolves from the captive-breeding program into the wild in 2012, since no release had occurred since 2008. The letter also asks Salazar to allow the release of captive-bred wolves to New Mexico, which was currently prohibited.
August 8, 2012 – A kill order was issued by the Fish and Wildlife Service to its sister agency, U.S.D.A. Wildlife Services, to shoot the alpha female of the Fox Mountain Pack of Mexican gray wolves due to the seven-member pack preying on four head of cattle over several months. Center action resulted in her captured instead of killing.
November 20, 2012 – The Center called on the Fish and Wildlife Service to dramatically increase the number of wolves in the wild in order to stave off genetic inbreeding, deemed by scientists to be limiting the size and health of some wolf litters.
November 28, 2012 – The Center filed suit challenging the Service’s failure to respond to our 2004 petition calling for implementation of sweeping reforms in the management of the Mexican gray wolf population, which had by then grown by only three animals, leaving just 58 wolves in the wild.

December 26, 2012 – After Mexico released nine Mexican gray wolves near the U.S. border in the Sierra Madre — and since wolves from the northern Rocky Mountains could make their way south at any time — the Center filed a formal notice of intent to sue the Service over its decision to grant itself a “recovery permit” to live-capture endangered wolves that may enter New Mexico and Arizona from Mexico or the Rocky Mountains.
February 2013 – A four-year stalemate in federal efforts to reintroduce Mexican gray wolves to the Southwest took another step backward last week when the U.S. Fish and Wildlife Service recaptured a male wolf only three weeks after his release into the wild.
February 6, 2013 – A census conducted by federal, state and tribal agencies showed that pup births boosted the number of Mexican gray wolves in the wild for the third year in a row, up from 58 wolves in 2011 to to 75 wolves, including 38 in New Mexico and 37 in Arizona. However, the number of breeding pairs decreased from six in the last count to just three.
March 28, 2013 – The Center filed a lawsuit challenging a permit issued by the Fish and Wildlife Service to allow federal and state agencies to capture wolves that enter Arizona and New Mexico from either the north or the south and keep them in captivity indefinitely.

November 20, 2013 – Local activists from the Center and allies will rally in Sacramento to voice their opposition to a Service proposal to strip Endangered Species Act protections from gray wolves across most of the lower 48 states.
