Identifying Characteristics for Canis lupus lycaon-Eastern Timber Wolf
Height at shoulder is 26"-36".
Weight ranges from 65-85 lbs.(female) to 80-95 lbs.(male), occasionally exceeds 100 lbs.
Length from nose to tip of tail 5'-6'(female) to 5.5'-6.5'(male).
Tracks are generally 3.5"-4" wide and 4.5"-5" long.
Ears are more rounded and shorter than those of the coyote.
Color varies from white to black with varying shades of gray or tan. Coyotes are seldom white or black.
Most wolves live in family units called packs. The family structure consists of the breeding pair and their offspring which may include subordinate adults, one year old juveniles, and pups. Pack size usually numbers less than eight individuals and is dependent upon mortality of adults and dispersal of pack members.
Wolf packs have very complex social structures. To maintain group order, wolves have a highly developed system of communication which includes many different facial expressions, body postures, and vocalizations. Such communications are essential to maintain the structure and survival of the pack.
Normally, only the dominant (Alpha) pair in a pack breeds. Mating occurs in February-March with an average of 4-7 pups born 63 days later. Approximately 50% of the pups do not survive their first year due to such factors as injury, disease, and starvation.
Wolves are opportunistic and do kill healthy prey if they are able to catch them. Generally, however, it is the weak, sick, crippled, parasite infested, young or old prey that are most vulnerable. By culling unfit prey, wolves play a vital role in the process of natural selection. In Yellowstone Park, wolves are promoting increased biodiversity as they kill coyotes, and through predation on elk, provide carcasses that benefit grizzlies and scanvengers such as eagles and wolverines.
Wolf packs occupy territories that may range in size from less than fifty to more than one thousand square miles. Factors affecting territory size include size of area available, number of wolves in the whole population, and density of prey.
Approximately sixty percent of young wolves leave their family packs (this phenomenon is known as dispersal), most doing so by two years of age. Dispersing wolves leave their natal territory to find a mate and an unoccupied territory in which to begin a new pack. They have been documented to travel more than five hundred airline miles during dispersal.
Wolf occupied territories are some seventy five miles from the Maine border in and adjacent to the Laurentide Reserve in southern Quebec. Known wolf range extends south to the north shore of the St. Lawrence River, within fifty miles of Maine. In August 1993, a two year old female eastern timber wolf was killed by a hunter from Pennsylvania northwest of Moosehead Lake. The animal was identified as a wolf through DNA comparison with a known wolf from eastern Canada.
The Province of Quebec allows the hunting and trapping of wolves south to the Maine border for more than five months of each year. Although, according to the Quebec government, wolves have not been documented south of the St. Lawrence River, there is apparently no requirement that wolves shot or trapped in this area be reported. Trapping is also permitted within the Laurentide Reserve, where population density is estimated to be one wolf per sixty square miles.
Wolves feed primarily on ungulates. In Maine, they would feed primarily on moose, deer and beaver. In recent years, Maine's pre-hunting season deer and moose populations combined have approximated 400,000 animals. A recovered population of 100 wolves (approximately 15-25 packs) would annually take less than one percent of either the pre-hunt or post-hunt populations of deer and moose combined and far fewer than the number of animals killed annually in collisions with motor vehicles.
According to the recovery plan for the eastern timber wolf which was developed by the U.S. Fish and Wildlife Service, Maine and northern New Hampshire contain some 12,800 square miles of potentially suitable wolf habitat.
Wolves do not require wilderness. They do require a healthy prey base, sufficient habitat, and most importantly, tolerance by people who allow them to survive. Timber harvesting and wildlife management practices that promote a diverse and productive forest are beneficial to wolves.
Wolf recovery can result in economic benefits. In a Federal Environmental Impact Statement, it was estimated that wolf recovery in Yellowstone would result in increased visitor expenditures in the region in the amount of $23,000,000.00 per year. The International Wolf Center located in Ely, Minnesota (pop. 4,000), averages some 50,000 visitors annually. Wolf related ecotourism (howling and tracking) is becoming increasingly popular in both the U.S. and Canada, such as in Quebec's Jacques-Cartier Provincial Park and Laurentide Reserve. In the summer of 1997, one ecotourism company in the Reserve had 3000 customers for its wolf howling excursions.
