Wolves and Deer Harvest in Minnesota
These seasonal dietary patterns were reflected in seasonal wolf spatial resource selection and resulted in contrasting spatial relationships. More wolves d. Discussion 5. How would you describe the relationship between a deer and wolf population sharing an ecosystem? What patterns do you see in. Abstract: Survival of yearling and adult white-tailed deer (Odocoileus virginianus) was monitored f sure of this relationship between wolves and.
This is not the case with wolves. Pack size for wolves is determined by food supply and by mating practices. The alpha male and female are the only pair that mate within the pack, producing one litter per year.

If the unit is lucky, perhaps 2 or 3 offspring will survive to adulthood. Aspen trees are once again flourishing. Before, elk had heavily browsed the river valleys where the trees grow.
Both elk and bison populations are healthier and stronger, and the number of coyotes has decreased. An epidemic of chronic wasting disease in Wisconsin has thinned deer herds in much of the state, but in the north, where wolves prey on deer, the disease has not taken hold and the herds remain vigorous.
Resulting in stronger, healthier deer. This has preserved the environment in which trout thrive. For example, hunters killeddoes andbucks in Wisconsin inwhen the state contained only about 40 wolves.
- The Relationship Between Wolves and Deer
The wolf is considered a cornerstone species buy many ecologists, in that it has positive affects on a whole array of ecosystems. If the wolf were to return to the Adirondacks, the natural balance of wildlife would be restored: Fewer beavers would mean less destruction of timberland and less flooding of streams.
Wolf & Deer Populations
Since wolves tend to take the sick, the old and the less fit, their presence would lead to stronger, healthier moose and deer herds.
If chronic wasting disease does enter the Adirondacks, wolves would slow its spread by culling out the diseased deer. Likewise, a brain worm that is transmitted from deer to moose would be less likely to become epidemic, thus boosting the survival rate of the moose, which is returning to the park on its own. The Native Americans hunted side by side with the wolf, and as far as we can tell the wolf never depleted the food resource.
The Native Americans had a saying. Dawson reached for the camera and turned it on. But I was conflicted as I watched the bear streak out of the area.

The Surprising Relationship Between Wolves & Bears
The black bear is a prime example. Many bear hunters, guides and outfitters are getting a wake-up call about how the high numbers of wolves and low numbers of deer are affecting the amount of predation on black bears. On my bear baits in Minnesota, I have seen active bear baits go completely dead when wolves move into the area.
And what better place to find a bear than the high-percentage area in the vicinity of a bear bait? Once the wolves arrive, baits often go dead as the bears abandon them. In fact, most biologists are very reluctant to say anything that would cast wolves in a bad light. Considering the emotionally-charged political climate surrounding wolves, many people within the game departments of states where wolf populations are at issue just seem to avoid the subject. Mike Foss, a long time bear hunting outfitter in Northern Wisconsin is frustrated by the lack of understanding about how much effect wolves have on bear populations.
He has come across the remains of bears killed by wolves in the forests and he feels the problem is increasing. He cites a fellow guide who found evidence of wolf predation at three bear dens late last winter.
He says wolves will kill bears whenever they have the right opportunity. One of his guides is a veteran wolf trapper who claims to have come across many cases where wolves have caught bears in their dens, drug them out and killed them. Wolves will also target cubs all year whenever they are far enough from a climbable tree. Here a hunter examines a bear mostly eaten by wolves. In that part of Manitoba, trappers and hunters target wolves all winter which helps keep the problem somewhat under control.
But in Wisconsin, the lack of opportunities to control wolf populations along with mild winters has created a perfect storm for high predation rates and many bear enthusiasts are becoming alarmed.
There are more cameras in the woods than at any time in the past, and instances of interactions between bears and wolves are on the rise. The advent of phones with cameras has added to the documentation of wolf predation on bears.
Blogs, social media and YouTube have examples with photos and videos show evidence of bears being pulled from the dens and eaten by wolves. But are the cameras just catching what has been common all along, or are the numbers of bears being killed by wolves on the rise? Mike Foss feels that wolves are targeting bears more and more.
I believe that is probable. One of the most simple solutions of course would be to harvest more wolves and bring their population back into balance. In the western US, that move is underway as wolf hunting is a growing sport.
