Wolves And Ungulates: How Are The Prey Items Doing?

A good deal of wolf behavior and pack behavior deals with the hunting and catching of prey.  These wolf activities often evoke emotional responses in the surrounding community, from hunters and ranchers to those people who just have strong opinions on just about everything.  A common response is that the wolves are killing all the ungulates such as deer, elk, and moose.  A variety of concerns then stems from these notions.  They range from a lack of hunting opportunities because ungulate populations have supposedly been reduced by the wolves, to government agencies regulating access to the national forests in their attempt to control the number of ungulates killed by hunters.

The notion that wolves and other predators are killing and drastically reducing ungulate populations is not supported by the scientific data.  Several studies have been conducted demonstrating that ungulate populations are doing extremely well, even in the presence of wolves and other predators.  The references for some papers that have been published from northwest Montana are provided below:

I received these references from Tom Meier, the U. S. Fish & Wildlife Service biologist in charge of overseeing the progress of wolf packs in northwest Montana.  He has since moved on to Denali National Park in Alaska.  Here are some of his thoughts regarding the local ungulate populations in northwest Montana:

I think that the conclusion of much of Kyran Kunkel's work is that multiple predators can in fact depress populations of prey. But winter severity is probably the biggest factor in prey numbers. In Minnesota and Wisconsin, after a series of mild winters, deer are so numerous that both states have had to steadily liberalize deer hunting regulations in order to kill more deer. With 3000 or so wolves, Minnesota last year, for the first time, made it possible for deer hunters to kill as many as 5 deer in the season. Wisconsin deer regulations are even more liberal. Here in NW Montana, I don't think anyone could dispute that deer have come back dramatically since the last severe winter, even as wolf numbers increased.

During the 2004 hunting season, northwest Montana reached record levels of harvest for many of the hunted ungulate species, which helps support the conclusions of scientific studies.  Despite the evidence, however, some people will continually insist that wolves are killing all the game animals. Where these attitudes come from is explored in the section on bigotry. In addition, the article Local Issues looks at how the Fishtrap pack has been blamed for killing all the deer locally. During my surveys for the wolves, I collect data on the number of deer and other animals present in the wolves' territory. The data demonstrates there is currently a great number of deer in the woods, as well as elk and moose, despite the presence of the Fishtrap pack.
