Conservation CATalyst

The first publicly released video of the only known wild jaguar in the United States shows the giant cat roaming around a creek and other parts of a mountain range in southern Arizona.

El Jefe — Spanish for "the boss" — has been living in the Santa Rita Mountains, about 25 miles south of downtown Tucson, for over three years.

Conservationists tracking the jaguar released a short video Wednesday showing him walking around mountain terrain.

The U.S. Fish and Wildlife Service says they do not know why two Mexican gray wolves died after being tranquilized and captured by the agency’s biologists. The deaths happened during the annual population survey of the endangered animals in eastern Arizona and New Mexico. Arizona Public Radio’s Ryan Heinsius reports.


Wildlife officials are investigating the deaths of two Mexican gray wolves they say were killed after being struck by a field team's tranquilizer darts.

The team of state and federal wildlife officials was surveying the wolves in an annual population count that also involves capturing wolves with tranquilizer darts to attach radio collars to them.

In a statement Tuesday, the Arizona Game and Fish Department and the U.S. Fish and Wildlife Service said one wolf was darted Jan. 23 and released into the wild before dying four days later.

A federal court ruled yesterday a lawsuit over lead ammunition on the Kaibab National Forest will be allowed to continue.

Utah state officials are balking at the possible inclusion of southern Utah in a recovery zone for the Mexican gray wolf.

The Utah Wildlife Board says in a letter sent this week to the Department of the Interior that science shows the northern limit of the species' range is in central New Mexico and Arizona. The board called the plan bad policy, bad science and bad for the Mexican gray wolf.

The board's letter dovetails with a similar one sent last month by Utah Gov. Gary Herbert and governors in Colorado, New Mexico and Arizona.

The U.S. Fish and Wildlife Service will award more than a quarter-million dollars to Arizona and New Mexico wildlife agencies. The grant is designed to develop nonlethal methods of protection of Mexican gray wolves and livestock. Arizona Public Radio’s Ryan Heinsius reports.

The U.S. Forest Service must reexamine a plan for allowing cattle to graze near Fossil Creek on the Coconino National Forest. A court has ruled the current plan jeopardizes habitat for the threatened Chiricahua leopard frog.

The U.S. Fish and Wildlife Service has proposed removing the Hualapai Mexican Vole from the list of endangered species. Genetic evidence suggests their numbers are more widespread in Arizona than previously believed.

The Hualapai Mexican Vole was originally listed in 1987 as a subspecies confined mainly to the Hualapai Mountains in the northwestern corner of Arizona. Now researchers question whether that designation is correct.

Two historical sites in Arizona have been labeled as “endangered” by a national organization. As Arizona Public Radio’s Aaron Granillo reports, the Grand Canyon and Oak Flat on the Tonto National Forest made the list of “America’s 11 Most Endangered Historic Places.”
