Wolf packs tend to be discriminatory in the use of their territory, using some portions more than others; this appears to be related to differences in physiography and deer densities, as well as proximity of neighboring wolf pack territories (Ho skinson and Mech 1976; Mech 1977 a,b,c; 1994; Fritts and Mech 1981).

Food habits of wolves on barren-ground caribou range. This time, not so. Snowshoe hares (Lepus americanus) are consumed by wolves year-round, and although the number of individuals consumed may be second only to deer, the biomass contributed to the diet is rather insignificant (Fritts and Mech 1981, Fuller 1989). St. Paul. Trends and management of wolf- livestock conflicts in Minnesota. The Journal of Wildlife Management 40:429-441. DelGiudice, G. D., L. D. Mech, and U. S. Seal. 1978. Wolf predation on deer is greatest during mid-late winter, coinciding with the period of poorest condition and deepest snow (Mech and Frenzel 1971, Mech 1977 b, Moen and Severinghaus 1981, DelGiudice et al. Current techniques in the study of elusive wilderness carnivores. 1996. It seems to go against all reason. Van Ballenberghe, V., and L. D. Mech. Minnesota’s 1971 deer hunting season was closed, a practice which had been exercised intermittently by the state in the past. Two principal factors positively impacting the growth of the deer population have been (1) alterations of their habitat by timber harvesting, fire, and agriculture; and (2) increasingly intense management directly by manipulation of the population’s sex and age composition (through hunting) and indirectly via habitat management programs. 43. Bears, deer and people followed, but the exact timing of the influx is unclear. A state program which compensates farmers for livestock lost to wolves, paid an average $37,299 per year over the past 5 years. Scent-marking in wolves. Relationship between snow depth and gray wolf predation on white-tailed deer. In 1974, wolves were fully protected statewide by the Endangered Species Act of 1973. Canadian Field-Naturalist 92:91-94. Proceedings of symposium of the Minnesota Chapter of the Wildlife Society, Section of Game, Minnesota Department of Natural Resources, St. Paul. 11pp. Surplus killing of white-tailed deer by wolves in northcentral Minnesota. Assessing the relationship of conifer thermal cover to winter distribution, movements, and survival of female white-tailed deer in northcentral Minnesota. Mech, L. D. 1994. 1961. Fawns are an important food item in the summer diet of wolves in the Lake Superior region (Thompson et al. But you know how wolves are. Severe winter weather negatively impacts survival of northern white-tailed deer either through nutritional restriction when predators are scarce or by predation where wolves or other predators are common (Severinghaus 1947; Erickson et al. Voigt, D. R., G. B. Kolenosky, and D. H. Pimlott. 10pp. Mech, L. D. 1974. The trainer could hear the wolves inside, pawing and clawing away as they seemed to be saying in wolf language, “Let me at ’em!”. The wide dispersion of does prior to fawning and the reduced home range sizes during the fawning season appear to be antipredatory strategies—newborn fawns attempt to avoid predation by hiding not fleeing. Prior to European settlement (before 1860), deer were most common in the hardwood forests of central and southeastern Minnesota and were relatively rare in the pine (Pinus spp.) 2005, SAND et al. There is a process through which we can be alerted to spiritual dangers.”. 1992), and occupied wolf range had increased to 57,050 km 2 (22,027 mi 2), nearly double the estimate for 1950-1952 (Fuller et al. 105. Deer distribution in relation to wolf pack territory edges. From 1976 to 1995, the state’s deer population increased rather steadily with record harvests being documented (MNDNR 1974, 1997). Pimlott, D. H., J. 1992). Mech, L. D., and M. E. Nelson. Morges, Switzerland. Effect of snow depth on wolf activity and prey selection in northcentral Minnesota. Geol. The last native Irish wolf was hunted down and killed in the late 1700s; In October 2019, there were calls for wolves to be reintroduced in Ireland, as part of a rewilding strategy in a wider national land use plan 1997. He stands up to them and scares them off, yelling, “Never come back!”. With only the trainer’s quick flip of the latch to open the trailer, the wolves would have reached the deer before they could take more than a few steps. By 1941, the highest wolf densities (estimated 39 wolves/1,000 km 2 [386 mi 2], Olson 1938) occurred in the northern third of Minnesota (Surber 1932, Fuller et al. Minnesota was divided into Deer Management Units and Permit Areas (subunits) following the closed season of 1971. DelGiudice, G. D. 1998. In the past in the central Superior National Forest, the collective effect of such dynamics involved a local wolf population that decreased 50% in 4 years (Seal et al. Other mammals documented in the diet of wolves include bog lemming (Synaptomys sp. 1969. Nelson, M. E., and L. D. Mech. The Journal of Wildlife Management 44:253-258. It appears, then, that cougars and wolves are the most effective deer predators. 238pp. Relationship between winter severity and wolf depredation of domestic animals in Minnesota. Forest Service Research Paper NC-148. 1978). Thus far, there is little evidence to show that wolves are a limiting factor on deer, or alone, have caused population declines (Voigt 1990). Further, several studies have observed a preponderence of deer-kills by wolves along the edges of wintering yards and more adult male than female deer killed by wolves during winter, which may be related to differences in the spatial distribution of the adults of the sexes in the yards (Stenlund 1955, Pimlott et al. Pages 83-88 in D. H. Pimlott, ed. 177pp. Ontario Dep. 1970. The Journal of Wildlife Management 36:357-369. 1975, Fritts and Mech 1981). Estimating wolf densities from radio telemetry data. Minnesota Department of Natural Resources, St. Paul. Fuller, T. K. 1990. Also during this period, the number of wolves captured and removed from the population has increased from 30-35 per year to just over 200 per year; the average has been 158 wolves captured per year during the past 5 years (Paul 1997). Similarly, in northwestern Minnesota, the average ages of deer (both sexes) killed by hunters and wolves were 3.3 and 7.6 years, respectively (Fritts and Mech 1981). Kunkel, K. E., and L. D. Mech. An analysis of the age, sex, and condition of deer killed by wolves in northeastern Minnesota. Lands and Forests Research Paper (Wildlife) 87. Canadian Journal of Zoology 72:1557-1565. Historical Background Mammalian dispersal patterns. Why would the deer move closer to the very wolves that could destroy them? Moreover, there is good evidence that pairs of wolves in a given area have higher winter kill rates of deer per wolf than packs of wolves (>/=3 members), suggesting a low optimum pack size for maximizing energy to individual members (Fritts and Mech 1981, Schmidt and Mech 1997). St. Paul. A study of the timber wolf population on the Chippewa National Forest, Minnesota. Pages 18-1 to 18-15 in Planning for Minnesota fish, wildlife, and native plant resources. 1975; Van Ballenberghe and Mech 1975; Mech 1977a,b, 1986). Beaver (Castor canadensis) have been found in the diet of wolves in spring and summer (Byman, unpublished thesis, Frenzel 1974, Fritts and Mech 1981, Fuller 1989); data indicate that its importance may be greater in northeastern than northwestern Minnesota.

Whenever you hear, see, or face the threat of spiritual wolves, run away from them or make them run from you! The variation of mortality rates of deer from area to area and year to year are primarily attributable to variations in deer:wolf ratios, winter severity, presence of alternate prey (e.g., moose), and the sex and age composition of the deer populations. forests east and north of the Mississippi River (MNDNR 1990). Bounties for wolves and all predator species were discontinued in 1965, and in 1966, wolves were classified by the federal government as an “endangered species, but legal harvests continued through 1973. A preliminary study of distribution and numbers of cougar, grizzly, and wolf in North America. Further, the factors directly responsible for the changes in their numbers are somewhat different from those affecting deer. We returned a couple of hours later and were amazed to see a deer standing less than 15 feet from the trailer. ), and woodchuck (Marmota monax) (Young and Goldman 1944, Fritts and Mech 1981). 1975. Dickson, T. 1992. Pages 27-40 in B. D. Chepko-Sade and Z. Halpin, eds. 1962. Mech, L. D. 1977 a. Title 50. As mentioned above, many other factors will interact, influence the specific dynamics of the relationship (what changes occur and the magnitude of those changes) and determine the temporal scale over which they occur. Minnesota Department of Natural Resources, St. Paul. Olson (1938), Murie (1944), and Young and Goldman (1944) pioneered ecological study of wolves and their prey. 23pp. At what age can you start going to school dances? In 2008, there were 700 moose and 23 wolves. 384pp. Winter home ranges are the smallest with reported average sizes ranging between 18 and 36 ha (44-89 ac) for all sex and age classes (Nelson and Mech 1981; G. D. DelGiudice, unpublished data). Summer habitat of white-tailed deer in northcentral Minnesota. The bear takes on the pack and a huge battle between the two groups followed Credit: mediadrumworld.com. Journal of Mammalogy 56:44-63. The wolves caught and killed it. The deer was so focused on that wolf-harboring trailer that she didn’t even notice us until we were about 15 feet away. Interestingly, preliminary evidence has suggested that the territorial buffer zones of wolf packs may have real significance for the long-term persistence of deer populations in Minnesota’s forests. 1977. Kruuk, H. 1972. St. Paul. What should I tell them? 1991. The first big game law affecting deer in Minnesota was established in 1858, although enforcement was likely difficult (MNDNR 1974). Summaries of wildlife research findings. Thompson, D. Q. 1975. In a study of wolves and deer in north-central Minnesota (Bearville study area north of Grand Rapids), Fuller (1990) documented an annual wolf-caused mortality rate of 0.04 for radio-collared deer >/=1.0 year old (both sexes) during the period 1981-1986.
