Current Population Status

The end of year census for 2019 was a minimum of 163 Mexican wolves in the wild (76 in AZ and 87 in NM). This was a 24% increase in the population from a minimum of 131 wolves counted at the end of 2018. 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 pup mortality generally occurs in this period). Thus, the IFT summarizes the total number of wolves in the winter at a fairly static or consistent time of year. Counting the population at the end of each year allows for comparable year-to-year trends at a time of year when the Mexican wolf population is most stable.

At the end of July, there were 37 named wolf packs (18 in AZ and 19 in NM) and 6 single collared wolves. There were 88 wolves with functioning radio collars that the IFT was actively monitoring. Not all of the wolves in the population are collared. Studbook numbers following individual pack names below denote wolves with functioning radio collars.
