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.
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 M1338 and F1335)
In May, the Bear Wallow Pack was located within their traditional territory on the SCAR and in the east central portion of the Apache-Sitgreaves National Forest (ASNF). They have displayed localized behavior consistent with denning.

In May, the Bluestem Pack continued to use their traditional territory in the east central portion of the ASNF. Male pup 1574 showed dispersal behavior and has been traveling with the Panther Creek Pack. Female pup 1562 has shown dispersal behavior and is believed to be traveling alone. The IFT documented the breeding pair AF1042 and AM1341 together with F1489 and fp1563. The Bluestem Pack displayed behavior consistent with denning within their traditional territory during May.
Elk Horn Pack (collared AF1294, mp1471, mp1474 and fp1473)

The IFT initiated a supplemental food cache near the den as part of the cross-foster effort.
Prime Canyon Pack (collared F1488)
In May, F1488 and an unknown wolf continued to travel together within a territory in the east-central portion of the ASNF. This pack did not display denning behavior in May.

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.
