Gray Wolf Biology and Status

Usually only the alpha pair breeds, however, in areas where there is a high ratio of prey per wolf there can be multiple litters per pack. In the basics wolves breed in February through March and have an average of six pups. The gestation period is 63 days so pups are born in April or May.

    Pup Survival
Pup survival is directly related to prey availability. Prey availability is generally higher in areas that are being newly colonized by wolves, where wolves have been recently reintroduced, or where adult wolves are harvested

    Adult Survival and Longevity
The overall survival of yearling and adult wolves has been documented to vary between 60% and 80%. Gray wolves are known to live up to 13 years in the wild and 15 years in captivity.

    Pack and Territory Size
The number of individuals per pack can be highly variable, but averages four to eight during winter with records of up to 16. Pack size can be as high as 30 or more. A wolf pack will roam and defend a territory of between 42 and 100 miles.

    Dispersal and Ability to Colonize New Areas
Dispersal is the primary way wolves colonize new areas and maintain genetic diversity. Wolves have been known to disperse up to 550 miles, but more commonly disperse 50 - 100 miles from their natal pack. Generally wolves disperse when 1 - 2 years old although some adults disperse also. At any one time 5 - 20% of the wolf population may be dispersing individuals. Usually a wolf disperses to find an individual of the opposite sex, find a territory, and start a new pack. Some dispersers join packs that are already formed.

    Habitat Requirements
Wolves can occur wherever there is a sufficient number of large ungulates such as deer, moose, elk, bison, and musk ox. Wolves were once considered a wilderness animal, however, if human-caused mortality is kept below certain levels, wolves can live in most areas. Historically, they once occupied every habitat that had sufficient prey in North America from mid Mexico to the polar ice pack.

    Food Requirements
Wolves can survive on 3.7 pounds of food per day, but require about five pounds per day to reproduce successfully. Wolves are estimated to eat 10 pounds of food per day on average. Wolves don't actually eat every day, however, as they live a feast or famine lifestyle. They may go several days without a meal and them gorge on over 20 pounds of meat when a kill is made. Wolves primarily feed on white-tailed deer, but supplement their diet with moose, beaver, hare, and other animals.

Reductions in the deer herd caused by wolves increases habitat quality and helps rid the herd of genetically unfit and diseased individuals. This results in long term maintenance of a healthier deer herd. Deer and wolves have evolved together and wolf predation has played a crucial role in making the deer what it is today.
