Service Seeks Input as it Prepares to Update the Mexican Wolf 2015 Revised Nonessential Experimental Population Designation

April 2020
The U.S. Fish and Wildlife Service (Service) is soliciting input from the public as it begins preparing a supplemental environmental impact statement (sEIS) on its 2015 revision to the nonessential experimental population of Mexican wolf. The scoping process gives citizens an opportunity to provide input on the range of issues that will be addressed in the sEIS.

  Mexican Wolf Population Rises to at Least 163 Animals

March 2020
The wild population of Mexican wolves continues to grow at a healthy pace. The recent Mexican wolf count shows the population of Mexican wolves has increased by 24 percent since last year, raising the total number of wolves in the wild to a minimum of 163 animals.

That number is among the findings of the Mexican Wolf Interagency Field Team (IFT), a task force comprising federal, state, tribal and international partners. From November 2019 through January 2020, the team conducted ground counts in Arizona and New Mexico that concluded with aerial counts of Mexican wolves in January and February.

Dozen Zoo-Born Mexican Wolf Pups Find New Homes in Wild After Successful Fostering Effort

June 2019
Twelve Mexican wolf pups are now being cared for and raised by surrogate wild wolf parents after successful efforts to introduce them into existing wolf litters in Arizona and New Mexico. The young wolves were placed in their foster dens by scientists from the Mexican Wolf Species Survival Plan group and Interagency Field Team. The cross-fostering is part of an effort to restore the rare gray wolf subspecies to its former range and increase genetic diversity in the wild population.

  2018 Mexican Wolf Minimum Population Estimate

April 2019
The recent Mexican wolf count indicates that the population of Mexican wolves has increased by 12 percent since last year, raising the total number of wolves in the wild to a minimum of 131 animals. From November 2018 through January 2019, the Interagency Field Team (IFT) conducted ground counts in Arizona and New Mexico that concluded with aerial counts of Mexican wolves in February.

Among the IFT’s findings: 131 wolves are nearly evenly distributed – 64 wolves in Arizona and 67 in New Mexico. Last year, the team documented 117 wolves. This year’s total represents a 12 percent increase in the population of Canis lupus baileyi.

“The survey results indicate the Mexican wolf program is helping save an endangered subspecies,” said Amy Lueders, Regional Director of the U.S. Fish and Wildlife Service’s Southwest Region. “The Mexican wolf has come back from the brink of extinction, thanks to scientific management and the dedicated work of a lot of partners. With continued support and research, we can continue to make progress in Mexican wolf recovery.”

This year’s findings confirmed:

  • There are a minimum of 32 packs of wolves (two or more animals), plus seven individuals.
  • A minimum of 18 packs had pups; 16 of these packs had pups that survived to the end of the year.
  • A minimum of 81 pups were born in 2018, and at least 47 survived to the end of the year.
  • Seventy-nine wolves—60 percent of the population—wore functioning radio collars. The collars help researchers manage and monitor the population and are vital to collecting scientific information.

The discovery of cross-fostered wolves was a bright spot in the annual survey. The IFT last spring placed eight captive pups into four wild dens to boost the genetic variability in the wild population. The team began cross-fostering in 2014.

Service Finalizes Changes to Mexican Wolf Experimental Population Rule in Arizona and New Mexico

January 2015
Revises Mexican Wolf ESA Listing as Subspecies, Maintaining Endangered Status The U.S. Fish and Wildlife Service has finalized the revised rule under which Mexican wolves are managed in Arizona and New Mexico. The revised rule expands the area where wolves are allowed to occupy and increases the Service’s ability to further the conservation of one of the nation’s rarest mammals while being responsive to the needs of local communities. The final rule will be formally published in the Federal Register later this week.
