Guest Blog: Jaguars and Ocelots in Arizona by Pinau Merlin

Deep in the shadows of the night, a jaguar moves silently through the rugged terrain. Although rarely seen, we know both jaguars and ocelots are here because remote, motion-sensor cameras are documenting their presence in Arizona’s wild areas. The University of Arizona Jaguar Survey and Monitoring Project has established more than 140 remote-camera sites in 16 mountain ranges across Southeastern Arizona for a three-year study.

There are only a few of these neotropical spotted cats in Arizona, which is the northern edge of the range for both jaguars and ocelots, and they are so secretive and reclusive that we know little about their habits here. The cameras provide a non-intrusive method of identifying individual cats and learning about their habitat preferences. The spotted coats of  these cats camouflage them in the dappled sunlight and shade of the forest, but the spot patterns are also like fingerprints — unique to each cat. The camera sites are set up with dual cameras to photograph both sides of the animal, since the spot pattern is different on each side of the cat.

The only one currently known jaguar and several ocelots in Arizona are proving very adaptable, using a variety of  habitats. The jaguar has even been photographed in coniferous forest in the snow! Being generalists and opportunistic hunters also allows these cats to adapt well. In fact, these cats promote biodiversity and help to maintain a balanced ecosystem.  By preying on a variety of species, they prevent any one species from becoming dominant (as seen in the overabundance of deer in the Midwest) and out-competing the others, thus maintaining species diversity and habitat quality.

The presence of these spotted cats in Arizona is not a new phenomenon. Jaguars and ocelots have always roamed the state in low numbers. Some 66 jaguars and 17 ocelots have been documented over the last century, including females and kittens, although we have no females that we know of at present. The few ocelots and the jaguar that we now have need our help to continue to survive here. Open space and unfragmented habitat is their most important need. Ocelots are homebodies with relatively small home ranges, but jaguars require large home ranges of up to 150 square miles or more. They also need wildlife-friendly open-space corridors that allow them to move between mountain ranges.

You can help by voting for open-space bonds, supporting habitat-connectivity corridors, putting your land into conservation easements and maintaining native vegetation, and donating to organizations that are working to study and preserve these magnificent cats.

Fish and Wildlife Service Officially Designates Critical Habitat for Jaguars

Good news for Arizona’s elusive jaguars: The U.S. Fish and Wildlife Service has officially designated nearly 1,200 square miles in Arizona and New Mexico as “critical habitat” for jaguars. Under the Endangered Species Act, the designation prevents the federal government from approving any development project that would render the land unfit for jaguars.

As Ruth Rudner reported in Spotted in Southern Arizona, a story in our upcoming April issue, the Fish and Wildlife Service had designated about 850,000 acres in Southeastern Arizona and Southwestern New Mexico as critical habitat for the species. The revised designation, about 765,000 acres, excludes land on the Tohono O’odham Nation and at Fort Huachuca; in both those areas, efforts to preserve the jaguars’ habitat have already been implemented, the service said in a news release.

The designation will not halt development of the controversial Rosemont copper mine. A Fish and Wildlife Service spokesman told The Arizona Republic that the mine project had been extensively studied and deemed OK to go forward.

To learn more about the world’s third-largest cats and their history in our state, pick up our April issue when it hits newsstands later this month.
