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

Press Release: March 28, 2022
Mexican gray wolf population count increases, but lobos are still among rarest species in the southwestern U.S.

Phoenix, Arizona – In good news, the wild population of Mexican gray wolves has seen a small increase this past year... The number of wolves increased slightly to a minimum of 196 wolves. However, this slight increase [...reveals] high mortality (including illegal killing), low pup survival, and a deepening genetic crisis [threatening] the wild population. [Also] the Service has held back well-bonded packs in captivity, instead of releasing them into the wild, despite suitable ... family groups being available... (click through for our 2-page PDF)
