1. What good
are wolves?
Like bald eagles, osprey, peregrine falcons, moose, fishers, martens, and trumpeter swans,
wolves play an important role in the ecosystem.
2. Do wolves present any danger to people?
There is no evidence of healthy wolves ever attacking humans in North America. Each year,
people occupy the same territories as wolves in northern Minnesota, Alaska, Canada, and
the Upper Peninsula of Michigan, including Isle Royale, and rarely see wolves, even in
ranges with relatively large wolf numbers.
3. How much do wolves weigh?
Adult female wolves in northeastern Minnesota weigh between 50 and 85 pounds, and adult
males between 70 and 110 pounds. The record for Minnesota is about 135 pounds. The record
for the world is about 170 pounds for an animal in Alaska, and there are informal records
of wolves weighing more than 200 pounds.
4. How many wolves are there in Minnesota?
Published figures indicate 1,550 to 1,750 for 1989, but they have continued to increase.
Current unpublished estimates indicate about 2,000 to 2,200 animals.
5. How many wolves are there in Alaska?
Between 5,227 and 8,060 according to 1995 estimates.
6. How many wolves are there on Isle Royale?
As of the winter of 1995/1996, there are believed to be 15 adults and 7 pups.
7. What states have wolves?
Alaska, Minnesota, Wisconsin, Michigan, Montana, Wyoming, Idaho and possibly Washington.
Within the last few years, several wolves have been killed in North and South Dakota
apparently having dispersed from Minnesota, but no known breeding populations reside
there. The red wolf, which is a different species from the gray but similar to it, has
been reintroduced into North Carolina and into Great Smoky Mountain National Park.
8. Does the Department of Natural Resources (DNR) plan to release wolves in Michigan?
No! The wolves present in Michigan are most likely from packs in Wisconsin, Minnesota, or
Ontario. The DNR has no plans to release wolves. Wolf recovery will occur from wolves
reproducing in the wild. We are, however, interested in protecting and managing wolves in
the state.
9. As wolves become established in Michigan, will state land be managed differently from
normal multiple use management?
No. Wolves do not require wilderness. They do require a healthy prey base, enough suitable
forest land to roam, and most importantly, a measure of tolerance by people who will allow
them to survive. Timber cutting, wildlife habitat management, and other practices that
promote a diverse and productive forest are good management practices for the wolf.
10. What is the main prey of wolves?
Wolves prey primarily on large, hoofed mammals. In Minnesota, the white-tailed deer is the
wolf's primary prey, with moose, beaver and snowshoe hare also being taken. Elsewhere,
wolves prey on caribou, musk oxen, bison, Dall sheep, elk, mountain goats, etc.
11. How many deer do wolves kill per year?
It would be about 18 deer per wolf per year if wolves only ate deer. However, since they
also eat moose and beaver, on the average the actual number of deer killed is about 15
adult-size deer per wolf per year. On October 1, 1994, the estimated deer population in
the Upper Peninsula of Michigan exceeded 65,000 animals. Although wolves will take some
deer, they will not have a significant impact, compared to other known losses. For
instance, 1994 data for the Upper Peninsula:
12. What about the compensation program
for wolf-killed livestock?
The State of Minnesota Department of Agriculture pays compensation up to $400 per animal
for livestock for which there is sufficient evidence that they were killed by wolves.
Before any payment is made, the incident must be investigated and verified by the U. S.
Department of Agriculture Animal Damage Control. The compensation program for the
Yellowstone National Park and Idaho Wilderness reintroduction efforts is paid by the
Defenders of Wildlife.
13. How much food do wolves require?
They can get along on about 2 1/2 pounds of food per wolf per day, but they require about
5 pounds per wolf per day to reproduce successfully. If given enough food, they will eat
over 10 pounds per wolf per day. The record of food a wolf can eat in one sitting is about
22.5 pounds.
14. How many pups do wolves have?
Average litter size is five to six.
15. What is a pack of wolves?
A pack is an extended family unit usually composed of an alpha (dominant) male and female,
young of the year, and a few others that may or may not be genetically related to the
alpha pair. Normally, only the alpha male and female breed. A new pack may develop when a
lone wolf leaves an established pack. This wolf will tend to hunt and feed alone, and if
it finds a mate and available territory, may form a new pack.
16. How large an area does a wolf pack cover?
In Minnesota, territories range from about 25 square miles per pack to 150 square miles
per pack, but in Alaska and Canada, territory sizes range from 200 to 1,000 square miles
each. Typically, a family of wolves will cover at least 100 square miles, about three
geographical townships. Wolves can travel great distances in a short time and can maintain
a dog-trot for 20 hours without stopping. The average travel of a wolf is 10 to 15 miles
per day, but some travel over 30 miles in a day. Their usual travel speed is about 5 miles
per hour. Some wolves have dispersed from Minnesota into Canada over 500 miles.
17. How big are wolf packs?
Generally six or eight wolves per pack, but in Alaska and northwestern Canada some packs
have included over 30 members. Pack sizes vary considerably, depending on number of wolves
present and available prey base. Michigan and Wisconsin wolf packs are normally small and
may contain as few as two animals. We would expect the typical pack in Michigan to have
six animals.
18. What is the social structure within a wolf pack?
Wolves have a dominant/ subordinate social structure consisting of an alpha male and
female. The alpha pair usually breed in February and pups are born in April. The litter is
tended in an excavated den by the alpha female. Other pack members hunt and return with
food for her while she is nursing the pups. It is common for the alpha female to move the
whole family to a new den site when the pups are five of six weeks old. This behavior is
thought to have come about as a way to avoid discovery of the den site. The social ranking
in the pack has served the wolf well through the years and helps perfect the hunting
strategy of the pack that the wolf is able to use successfully.
19. How long do wolves live?
In captivity, about 16 years. In the wild, it's difficult to tell but some have lived up
to 13 years and possibly longer. Nevertheless, most die before they reach 8 years of age.
20. What are the causes of death of wolves?
The natural causes of wolf death are primarily starvation which takes mostly pups, and
death from other wolves in territorial disputes. In most wolf populations, disease is not
a problem. Injuries from prey cause some deaths but not a very high percentage. Mange and
canine parvovirus may be a problem in Wisconsin and Michigan's recovering population.
21. What enemies do wolves have?
Aside from a few germs and parasites, bears are sometimes enemies of wolves. Even today,
humans have the greatest potential for decimating the wolf populations.
22. What happened to the wolves in Yellowstone?
They were exterminated deliberately by a government control program in the late 1920's. If
there were any wolves left there, they would just be loners passing through.
23. Can wolves be killed in Minnesota?
Only by the government if the wolves are involved in livestock depredations. In 1995, 78
wolves were killed this way all across northern Minnesota but primarily in north central
and northwestern Minnesota.
24. What is the legal status of the wolf in Minnesota?
The wolf in Minnesota is on the federal list of endangered species but is considered
threatened in Minnesota rather than endangered. Elsewhere in the 48 states, the wolf is
considered endangered. Endangered means in danger of going extinct; threatened means in
the foreseeable future could become endangered. The wolves in Alaska and Canada are not on
the endangered species list.
25. What is the status of Michigan wolves?
The gray wolf is listed as an endangered species in Michigan under both the state and
federal endangered species acts. The Upper Peninsula has at least 116 wolves scattered
throughout the Peninsula. The territories of several of these animals include parts of
nearby Wisconsin and the province of Ontario. A 1995 winter survey found 16 wolves on Isle
Royale. At least 12 packs have formed and successful breeding has occurred on the mainland
UP since 1991.
26. What is the penalty for killing a wolf in Michigan?
Under the Michigan Endangered Species Act, it is illegal to harass, harm, pursue, hunt,
shoot, wound, kill, trap, capture, collect or attempt to engage in such conduct. Penalties
for a violation under the state act may include a $1,000 fine and/or 90 days in jail. A
person convicted of illegally killing, possessing, purchasing, or selling a gray wolf must
also reimburse the state for the $1,500 assessed value of the animal. The federal act also
prohibits the taking of gray wolves. Maximum penalties are $100,000 per individual or
$250,000 for corporations or organizations, with up to one year imprisonment.
