Protect and Conserve Arizona’s Native Wildlife and Habitats

Arizona is an amazing and ecologically rich state, making it the ideal home for a wide diversity of species. Our state’s rich flora – almost 4000 species of native plants – is unequalled by few other regions of the United States and provides unique habitat for a wealth of animal species:

  • 36 native fish species
  • 25 native amphibians
  • 107 species of native reptiles
  • 534 species of birds (including 7 non-native species)
  • 138 species of mammals
  • Over 220 species of native snails and one native freshwater mussel
  • Tens of thousands of insect and arachnid species

Unfortunately, many of the species that inhabit our state are on the path to extinction. With 62 federally-listed endangered and threatened species – 45 animals and 17 plants – Arizona ranks within the top 10 states for listed species.

A hotter, drier climate is likely to drive more of these species closer to the brink, which is why it is essential to limit impacts from development, roads, water diversions, overgrazing of livestock, agriculture, nonnative species, and much more.

Our Goals

  • Maintain viable and sustainable populations of all native wildlife species
  • Preserve and restore natural habitats
  • Safeguard important habitat connectivity and corridors
  • Ensure greater resiliency in light of climate disruption by reducing and eliminating stresses

Current News/Take Action!

February 13, 2015, Phoenix, Arizona - Today the U.S. Fish and Wildlife Service (USFWS) announced that the wild Mexican wolf population has increased to 109 from 83 wolves counted at the end of 2013. While conservationists cheer this good news, they point out that the agency projected there would be 100 wolves in the wilds of eastern Arizona and western New Mexico by 2006. More than a decade later, the total population has finally reached that milestone, still a whisker away from extinction. Click here to read more (87 KB pdf).

December 15, 2014, PHOENIX, Arizona - Today conservation groups filed a formal objection to a plan by the Tonto National Forest to allow hundreds of helicopter landings in five Wilderness areas on the Tonto National Forest, ostensibly to "manage" bighorn sheep. The groups contend the action violates the Wilderness Act, the National Environmental Policy Act, the Endangered Species Act, the National Forest Management Act, and will harm wildlife including bighorn sheep, as well as other wilderness values.

November 25, 2014, FLAGSTAFF, Ariz. - The U.S. Fish and Wildlife Service (Service) released revisions to the federal rule governing endangered Mexican gray wolf reintroduction, which would obstruct the imperiled subspecies' recovery. The Service's Final Environmental Impact Statement (EIS) and draft record of decision propose alterations to government management of America's only wild population of one of the world's most critically endangered mammals.

November 21, 2014, GRAND CANYON NATIONAL PARK, Ariz. - The U.S. Fish and Wildlife Service has confirmed that a female northern Rockies gray wolf is roaming the North Kaibab National Forest near the North Rim of the Grand Canyon. This pioneer traveled hundreds of miles to northern Arizona, an area that scientists have said is one of the last best places in the Southwest for wolves. The Grand Canyon wolf is currently fully protected under the Endangered Species Act, but could lose those protections under an Obama administration plan to strip gray wolves of protections nation-wide.

April 25, 2014, PHOENIX - The Arizona Game and Fish Commission unanimously endorsed a plan this week that will make it vastly easier to kill endangered Mexican gray wolves in Arizona and New Mexico and arbitrarily caps the number of wolves in both states at 300, and allowing for a number as low as 125. Significantly, the commission also recommends that management of wolves be taken away from the federal government, where it has been since passage of the federal Endangered Species Act, and given to the state, which has long been hostile to wolves.

Santa Catalina Bighorn Sheep Restoration Project - Sierra Club has significant concerns about the Santa Catalina Bighorn Sheep Restoration Project. While we support restoration of native species to their natural habitat, we do question the efficacy of introducing animals to an area where they disappeared, where it is unclear why the population died out, and where a majority of the habitat is poor to fair. Read more in our letter to Arizona Game and Fish, our letter to the Forest Service, our letter to the Coronado National Forest and our Letter to Bighorn Sheep Population Management Project.

September 5, 2012, Suit Filed to Protect Wildlife From Lead Poisoning in Arizona’s Kaibab National Forest PHOENIX, Ariz.— Conservation groups sued the U.S. Forest Service today for failing to protect wildlife from toxic lead in spent ammunition in Arizona’s Kaibab National Forest. The Center for Biological Diversity, Sierra Club and Grand Canyon Wildlands Council filed suit under the Resource Conservation and Recovery Act, a federal law governing disposal of hazardous waste. Lead bullet fragments from hunting contaminate the food supply for Arizona wildlife such as condors, bald and golden eagles, northern goshawks, ferruginous hawks and ravens; and are also a hazard to human health for those eating game shot with lead ammunition.
