Mexican Wolf Reintroduction Project Monthly Update
May 1-31, 2017
The following is a summary of Mexican Wolf Reintroduction Project activities in the Mexican Wolf Experimental Population Area (MWEPA) in Arizona, including the Fort Apache Indian Reservation (FAIR), San Carlos Apache Reservation (SCAR), and New Mexico. Additional Project information can be obtained by calling (928) 339-4329 or toll free at (888) 459-9653, or by visiting the Arizona Game and Fish Department website at
Past updates may be viewed on either website, or interested parties may sign up to receive this update electronically.
This update is a public document and information in it can be used for any purpose. The Project is a multi-agency cooperative effort among the Arizona Game and Fish Department (AGFD), USDA Forest Service (USFS), USDA-Animal and Plant Health Inspection Service, Wildlife Services (USDA-APHIS WS), U.S. Fish and Wildlife Service USFWS) and the White Mountain Apache Tribe (WMAT).
Please report any wolf sightings or suspected livestock depredations to: the Alpine wolf office (928) 339-4329, Pinetop wolf office (928-532-2391) or toll free at (888) 459-9653. To report incidents of take or harassment of wolves, please call the AGFD 24-hour dispatch (Operation Game Thief) at (800) 352-0700.
Numbering System: Mexican wolves are given an identification number recorded in an official studbook that tracks their history. Capital letters (M = Male, F = Female) preceding the number indicate adult animals 24 months or older. Lower case letters (m = male, f = female) indicate wolves younger than 24 months or pups. The capital letter “A” preceding the letter and number indicate breeding wolves.
Our note: You will notice that some of the wolves also have names associated with their identification numbers. For the last five years we had a Pup Naming Contest for Kids to name the pups born in the Spring. The names that you see are the winning names that we have assigned to the pups. Follow these links for all the entries and results from the 2012 contest, 2013 contest, 2014 contest, 2015 contest and 2016 contest.
Definitions: A “wolf pack” is defined as two or more wolves that maintain an established territory. In the event that one of the two alpha (dominant) wolves dies, the remaining alpha wolf, regardless of pack size, retains the pack status. The packs referenced in this update contain at least one wolf with a radio telemetry collar attached to it. The Interagency Field Team (IFT) recognizes that wolves without radio telemetry collars may also form packs. If the IFT confirms that wolves are associating with each other and are resident within the same home range, they will be referenced as a pack.
CURRENT POPULATION STATUS
Annual surveys are conducted in the winter as this is when the population experiences the least amount of natural fluctuation (i.e. in the spring the population increases dramatically with the birth of new pups and declines throughout the summer and fall as mortality is particularly high on young pups). Thus, the IFT summarizes the total number of wolves in the winter at a fairly static or consistent time of year. This allows for comparable year-to-year trends at a time of year that accounts for most mortality and survival of young pups.
During annual year-end population counts, the IFT documented a minimum of 113 Mexican wolves in the wild in Arizona and New Mexico at the end of 2016. At the end of May, there were 58 wolves with functioning radio collars that the IFT was actively monitoring.
Wolves with functioning radio collars are listed by studbook number in the pack updates below.
Bear Wallow Pack (collared Poco-AM1338, Bailey-AF1335 and Zyanya-fp1548)

COMMUNICATION AND COORDINATION
On May 4 and 5, members from the IFT attended a ranching workshop hosted by the X Diamond Ranch in Arizona. The workshop provided a basic understanding of the principles and tools used in low stress livestock handling and stockmanship and a discussion of how these techniques have been used to reduce wolf depredations on cattle.
On May 17, the IFT gave a presentation on Mexican wolf biology, management and reintroduction efforts to a group of 6th grade children from Winslow at their annual camping trip in the ASNF.
