Food

Timber wolves are carnivores feeding on other animals. A study in the early 1980s showed that the diet of Wisconsin wolves was comprised of 55 percent white-tailed deer, 16 percent beavers, 10 percent snowshoe hares and 19 percent mice, squirrels, muskrats and other small mammals. Deer comprise over 80 percent of the diet much of the year, but beaver become important in spring and fall. Beavers spend a lot of time on shore in the fall and spring, cutting trees for their food supply. Since beavers are easy to catch on land, wolves eat more of them in the fall and spring than during the rest of the year. In the winter, when beavers are in their lodges or moving safely beneath the ice, wolves rely on deer and hares. Wolves' summer diet is more diverse, including a greater variety of small mammals.

Breeding biology

Wolves are sexually mature when two years old, but seldom breed until they are older. In each pack, the dominant male and female are usually the only ones to breed. They prevent subordinate adults from mating by physically harassing them. Thus, a pack generally produces only one litter each year, averaging five to six pups.
In Wisconsin, wolves breed in late winter (late January and February). The female delivers the pups two months later in the back chamber of a den that she digs. The den's entrance tunnel is 6-12 feet long and 15-25 inches in diameter. Sometimes the female selects a hollow log, cave or abandoned beaver lodge instead of making a den.
At birth, wolf pups are deaf and blind, have dark fuzzy fur and weigh about 1 pound. They grow rapidly during the first three months, gaining about 3 pounds each week. Pups begin to see when two weeks old and can hear after three weeks. At this time, they become very active and playful.
When about six weeks old, the pups are weaned and the adults begin to bring them meat. Adults eat the meat at a kill site often miles away from the pups, then return and regurgitate the food for the pups to eat. The hungry pups jump and nip at the adults' muzzles to stimulate regurgitation.
The pack abandons the den when the pups are six to eight weeks old. The female carries the pups in her mouth to the first of a series of rendezvous sites or nursery areas. These sites are the focus of the pack's social activities for the summer months and are usually near water.
By August, the pups wander up to two to three miles from the rendezvous sites and use them less often. The pack abandons the sites in September or October and the pups, now almost full-grown, follow the adults.

Distribution

Before Europeans settled North America, gray wolves inhabited areas from the southern swamps to the northern tundra, from coast to coast. They existed wherever there was an adequate food supply. However, people overharvested wolf prey species (e.g., elk, bison and deer), transformed wolf habitat into farms and towns and persistently killed wolves. As the continent was settled, wolves declined in numbers and became more restricted in range. Today, the majority of wolves in North America live in remote regions of Canada and Alaska. In the lower 48 states, wolves exist in forests and mountainous regions in Minnesota, Michigan, Wisconsin, Montana, Idaho, Wyoming, Washington, Arizona, New Mexico, North Dakota, and possibly in Oregon, Utah and South Dakota.

History in Wisconsin

Before Wisconsin was settled in the 1830s, wolves lived throughout the state. Nobody knows how many wolves there were, but best estimates would be 3,000-5,000 animals. Explorers, trappers and settlers transformed Wisconsin's native habitat into farmland, hunted elk and bison to extirpation, and reduced deer populations. As their prey species declined, wolves began to feed on easy-to-capture livestock. As might be expected, this was unpopular among farmers. In response to pressure from farmers, the Wisconsin Legislature passed a state bounty in 1865, offering $5 for every wolf killed. By 1900, no timber wolves existed in the southern two-thirds of the state.
At that time, sport hunting of deer was becoming an economic boost to Wisconsin. To help preserve the dwindling deer population for this purpose, the state supported the elimination of predators like wolves. The wolf bounty was increased to $20 for adults and $10 for pups. The state bounty on wolves persisted until 1957. By the time bounties were lifted, millions of taxpayers' dollars had been spent to kill Wisconsin's wolves, and few wolves were left. By 1960, wolves were declared extirpated from Wisconsin. Ironically, studies have shown that wolves have minimal negative impact on deer populations, since they feed primarily on weak, sick, or disabled individuals.
The story was similar throughout the United States. By 1960, few wolves remained in the lower 48 states (only 350-500 in Minnesota and about 20 on Isle Royale in Michigan). In 1974, however, the value of timber wolves was recognized on the federal level and they were given protection under the Endangered Species Act [exit DNR]. With protection, the Minnesota wolf population in-creased and several individuals dispersed into northern Wisconsin in the mid-1970s. In 1975, the Wisconsin Department of Natural Resources declared timber wolves endangered.
Intense monitoring of wolves in Wisconsin by the DNR began in 1979. Attempts were made to capture, attach radio collars and radio-track wolves from most packs in the state. Additional surveys were done by snow-tracking wolf packs in the winter and by howl surveys in the summer. In 1980, 25 wolves in 5 packs occurred in the state, but dropped to 14 in 1985 when parvovirus reduced pup survival and killed adults. Wisconsin DNR completed a wolf recovery plan in 1989. The recovery plan set a state goal for reclassifying wolves as threatened once the population remained at or above 80 for three years. Recovery efforts were based on education, legal protection, habitat protection, and providing compensation for problem wolves.
In the 1990s the wolf population grew rapidly, despite an outbreak of mange between 1992 -1995. The DNR completed a new management plan in 1999. This management plan set a delisting goal of 250 wolves in late winter outside of Indian reservations, and a management goal of 350 wolves outside of Indian reservations. In 1999, wolves were reclassified to state threatened status with 205 wolves in the state. In 2004 wolves were removed from the state threatened species list and were reclassified as a protected wild animal with 373 wolves in the state.

Current status (as of April 2012)

The wolf is a "Protected Wild Animal" in Wisconsin. After five years of delisting attempts and subsequent court challenges, a new federal delisting process began on May 5, 2011 and wolves were officially delisted on January 27, 2012. The count in winter 2011 was about 782-824 wolves with 202-203 packs, 19-plus loners, and 31 wolves on Indian reservations in the state.

Misconceptions and controversies

Wolves are the "bad guys" of fable, myth and folklore. The "big bad wolf" fears portrayed in "Little Red Riding Hood," "Peter and the Wolf" and other tales have their roots in the experiences and stories of medieval Europe. Wolves were portrayed as vile, demented, immoral beasts. These powerful negative attitudes and misconceptions about wolves have persisted through time, perpetuated by stories, films and word-of-mouth, even when few Americans will ever have the opportunity to encounter a wolf.
Wolves are controversial because they are large predators. Farmers are concerned about wolves preying on their livestock. In northern Wisconsin, about 50-60 cases of wolf depredation occur per year, about half are on livestock and half on dogs. As the population continues to increase, slight increases in depredation are likely to occur. In Minnesota, with about 3,000 wolves, there are usually 60 to 100 cases per year.
A few hunters continue to illegally kill wolves, believing that such actions will help the deer herd. It is important to place in perspective the impact of wolves preying on deer. Each wolf kills about 20 deer per year. Multiply this by the number of wolves found in Wisconsin in recent years (800), and approximately 16,000 deer may be consumed by wolves annually. This compares to about 27,000 deer hit by cars each year, and about 340,000 deer shot annually by hunters statewide. Within the northern and central forests where most wolves live, wolves kill similar numbers of deer as are killed by vehicles (about 8,000), and about 1/10 of those killed by hunters (8,000 in 2010). Wolves are a factor in the deer herd, but only one of many factors that affects the total number of deer on the landscape.

Research and management

The Wisconsin DNR has been studying wolves since 1979 by live capturing, attaching radio collars and monitoring movements. Much has been learned about wolf ecology in northern Wisconsin. In 1992, the department began a research project to determine the impact of highway development in northwest Wisconsin on wolves. A Geographic Information System, (computer mapping system) was used to determine that northern Wisconsin has about 6,000 square miles of habitat that could support 300-500 wolves. Recent studies suggest the state can perhaps support 700 to 1,000 wolves (in late winter), but this level may not be socially tolerated and recent federal delisting of wolves will allow the department to manage the wolf population toward sustainable but acceptable population levels.
The DNR recognizes wolves as native wildlife species that are of value to natural ecosystems and benefit biological diversity of Wisconsin. The department approved a Wolf Recovery Plan in 1989. The plan's goal of 80 wolves was first achieved in 1995 mainly through protection and public education programs, and did not require any active reintroductions into the state. In 1999, wolves were reclassified to threatened in Wisconsin, and a new wolf management plan was approved that set a state delisting goal at 250 and management goal at 350 wolves in late winter outside of Indian reservations. The wolf management goal represents a threshold level that allows the Department to use a full range of lethal controls, including public harvest, to manage the wolf population. Wolves were state delisted in 2004 and federally in 2012, returning management back to the state and Indian tribes. Landowners will be able to control some problem wolves on their land and government trappers will remove problem wolves from depredation sites.

• Invite native flora and fauna into your life.Maintain a birdbath. Replace part of your lawn with native plants. Build a bat house. For backyard suggestions, plus links to information about attracting wildlife to apartments and townhouses, see the National Audubon Society’s Invitation to a Healthy Yard. Make your yard a National Wildlife Federation (NWF) Certified Wildlife Habitat.
• Revive old traditions. Collect lightning bugs at dusk, release them at dawn. Make a leaf collection. Keep a terrarium or aquarium. Go crawdadding — tie a piece of liver or bacon to a string, drop it into a creek or pond, wait until a crawdad tugs. Put the garden hose to good use: make a mud hole. (Your kids will sleep well later.)
• Help your child discover a hidden universe. Find a scrap board and place it on bare dirt. Come back in a day or two, carefully lift the board (watch for unfriendly critters), and see how many species have found shelter there. Identify these creatures with the help of a field guide. Return to this universe once a month, lift the board and discover who’s new.
• Encourage your kids to go camping in the backyard. Buy them a tent or help them make a canvas tepee, and leave it up all summer. Join the NWF’s Great American Backyard Campout. (Pledge now to camp out on June 28.)
• Take a hike. With younger children, choose easier, shorter routes and prepare to stop often. Or be a stroller explorer. “If you have an infant or toddler, consider organizing a neighborhood stroller group that meets for weekly nature walks,” suggests the National Audubon Society. The American Hiking Society offers good tips on how to hike with teenagers. Involve your teen in planning hikes; prepare yourselves physically for hikes, and stay within your limits (start with short day hikes); keep pack weight down. For more information, consult the American Hiking Society or a good hiking guide, such as John McKinney’s Joy of Hiking. In urban neighborhoods, put on daypacks and go on a mile hike to look for nature. You’ll find it — even if it’s in the cracks of a sidewalk.
• Be a cloudspotter or build a backyard weather station. No special shoes or drive to the soccer field is required for “clouding.” A young person just needs a view of the sky (even if it’s from a bedroom window) and a guidebook. Cirrostratus, cumulonimbus, or lenticularis, shaped like flying saucers, “come to remind us that the clouds are Nature’s poetry, spoken in a whisper in the rarefied air between crest and crag,” writes Gavin Pretor-Pinney in his wonderful book The Cloudspotter’s Guide. To build a backyard weather station, read The Kid’s Book of Weather Forecasting, by Mark Breen, Kathleen Friestad, and Michael Kline.
• Collect stones. Even the youngest children love gathering rocks, shells, and fossils. To polish stones, use an inexpensive lapidary machine-a rock tumbler. See Rock and Fossil Hunter, by Ben Morgan.
• Encourage your kids to build a tree house, fort, or hut. You can provide the raw materials, including sticks, boards, blankets, boxes, ropes, and nails, but it’s best if kids are the architects and builders. The older the kids, the more complex the construction can be. For understanding and inspiration, read Children’s Special Places, by David Sobel. Treehouses and Playhouses You Can Build, by David and Jeanie Stiles describes how to erect sturdy structures, from simple platforms to multistory or multitree houses connected by rope bridges.
• Plant a garden. If your children are little, choose seeds large enough for them to handle and that mature quickly, including vegetables. Whether teenagers or toddlers, young gardeners can help feed the family, and if your community has a farmers’ market, encourage them to sell their extra produce. Alternatively, share it with the neighbors or donate it to a food bank. If you live in an urban neighborhood, create a high-rise garden. A landing, deck, terrace, or flat roof typically can accommodate several large pots, and even trees can thrive in containers if given proper care.
• Invent your own nature game. One mother’s suggestion: “We help our kids pay attention during longer hikes by playing ‘find ten critters’—mammals, birds, insects, reptiles, snails, other creatures. Finding a critter can also mean discovering footprints, mole holes, and other signs that an animal has passed by or lives there.” 

• For more suggestions, in addition to Last Child in the Woods, a number of recent books offer great advice, including Fed Up with Frenzy, by C&NN’s Suz Lipman, I Love Dirt! by Jennifer Ward, The Nature Connection by Clare Walker Leslie, and the free booklet A Parent’s Guide to Nature Play by Ken Finch. Also, the classic Sharing Nature With Children by Joseph Cornell. Online, Nature Rocks is another good resource.
