Bears are attracted to the garbage, pet food, compost piles, fruit trees and birdfeeders around houses.
DO make birdfeeders and bird food inaccessible by discontinuing the feeding of birds from late March through November or by hanging feeders at least ten feet above the ground and six feet away from tree trunks. DO place garbage in "bear-proof' garbage cans. If possible, do not leave your garbage cans out on the night before garbage pickup. Try to put the cans out on the morning of the pickup. DO eliminate food attractants by placing garbage cans inside a garage or shed. Add ammonia to trash to make it unpalatable. DO clean and store grills away after use. DO ecourage your neighbors to take similar precautions. DON'T intentionally feed bears. Bears that become accustomed to finding food near your home may become "problem" bears. Bears that associate food with people may become aggrerssive and dangerous. This may lead to personal injury and property damage. DON'T leave pet food outside overnight. DON'T add meat or sweets to a compost pile. Lime can be sprinkled on the compost pile to reduce the smell and discourage bears.
Black bears are impressive animals. Even a long-distance glimpse of one foraging in a woodland is an unforgettable experience for most outdoor enthusiasts. However, glimpsing a bear in New Jersey was once unlikely because bears were extirpated from the state by the mid-1800s. Since then, bears have made a comeback. Their return is due, in part, to the regrowth of forestland throughout the region following the abandonment of farms during the late 1800s. Beginning in the 1980s, the DEP Wildlife Division had evidence of a resident population. Since then, annual sighting reports have increased dramatically, indicating a rapid increase in the bear population. With the number of bears increasing in the state, it is important for residents to learn the facts about black bears and how to coexist with them.
The black bear is a stocky animal with short, thick legs. It is the smallest North American bear. In New Jersey, adult males, or boars, normally weigh from 150 to 400 pounds, while females, or sows, weigh from 110 to 200 pounds. Yearlings weigh 45 to 100 pounds. Adults are five to six feet long.
The black bear's coat is typically glossy black or brownish black, except for the muzzle, which is tan. There is sometimes a small, white patch on the chest. In western North America some black bears are brown or cinnamon. Black bears have five toes with large claws on all feet. Bear tracks resemble human tracks, but the front feet are shorter than the rear. A bear’s tail is short, from three to five inches long. The sexes are similar in appearance, although males are usually larger.
BLACK BEARS ARE EXCELLENT TREE CLIMBERS
Habitat and Diet
Black bear habitat is forestland, usually with deciduous and coniferous trees, as well as streams, swamps, and rock ledges. Bears prefer areas with thick understory vegetation and abundant food resources. Mature forests provide soft and hard mast in late summer and fall. Wetlands are particularly important in spring when emerging plants are one of the few available foods. Bears are omnivorous; they eat grasses, forbs, fruits, nuts, and berries. They also will seek insects (particularly ants and bees), scavenge carrion, and raid bird feeders and garbage cans. Bears occasionally will prey on small mammals, deer, and livestock.
Breeding occurs during summer, usually in late June or early July. During this time, males travel extensively in search of females. The age when sows first produce cubs is related to the available food supply, but most begin to reproduce at age three or four and continue to have young every two years. Bears do not form long-lasting bonds, so the males may mate with more than one female during the breeding season. Fighting may occur between rival males as well as between males and unreceptive females.
Young are born in the den during January or February and are blind, toothless, and covered with fine hair. Cubs weigh six to 12 ounces at birth. Litter sizes range from one to four cubs, with litters of two or three being most common. After giving birth, the sow usually continues her winter rest while the cubs are awake and nursing. Only females rear the young. Cubs are weaned when they are about seven months old and will remain with the female until the second summer of their lives. Then, the young bears, especially the males, may travel great distances in search of their own territories. Yearling females frequently settle near their mother’s home range. Young bears are often forced into less preferred habitat.
The black bear is an intelligent animal with keen senses of smell and hearing. It can detect the slightest aroma of food, which may lead the bear to campsites and near homes. Odor from carelessly stored food and garbage can lure bears long distances. Black bears travel and feed primarily at night, but can be active any time of the day. Climatic factors, such as drought, may result in a food shortage, causing bears to travel many miles in search of food.
Black bears are generally shy and secretive and usually fearful of humans. However, if they regularly find food near houses and areas of human activity, they can lose their fear of humans. Unlike grizzly bears, black bears are seldom aggressive toward humans.
Females with cubs tend to have restricted home ranges which average six to 19 square miles, while males move about widely in home ranges of 12 to 60 square miles. The size of a home range varies geographically and often depends on the quality of habitat. Most ranges are used by more than one bear, but specific areas are rarely used at the same time. Male and female ranges can overlap, but overlap among the same sex is less common. In their home territories, bears may mark trees (called “bear trees”) along their travel routes by clawing and biting the bark. Black bears are good tree climbers and strong swimmers. They also can run up to 35 miles per hour.
Black bears are not classified as true hibernators but their body temperature is lowered and heart rate slowed during winter denning. Denning enables bears to overcome unfavorable weather conditions and lack of food during winter. Denning bears do not eat, drink, urinate, or defecate. However, they will usually wake up if disturbed during their winter dormancy. Bears commonly den under fallen trees or in brush piles, but varied sites are used, including rocky ledges. Most dens are lined with leaves, grass, or rotted wood. In New Jersey, most bears den from late November through mid-March. Some individuals den for shorter periods.
Bears, particularly young bears, may be seen near residential areas. The DEP's response will depend on the specifics of each bear situation. The mere presence of a bear does not necessitate its removal. In most cases, if left alone, the bear will make its way to a more natural habitat. Removing food attractants, such as bird feeders, reduces the chance that bears will go near homes. The DEP seldom relocates bears. An exception is the removal of a bear from an urban location when there is little likelihood that it can leave safely on its own and when the bear is in a position where it can be safely immobilized. DEP Tranquilizing Teams, consisting of Environmental Conservation Police Officers and wildlife biologists, are trained and equipped to immobilize wildlife. Bears cannot be relocated to another state because no other state allows it. Bears that have persistent, serious, negative behavior, such as killing protected livestock or entering buildings, may have to be destroyed.
If people do not take precautions, problem behavior by bears can increase, possibly leading to bears being removed or destroyed.
If you see a bear:
Enjoy it from a distance.
Advertise your presence by shouting and waving your arms or walk slowly away.
Never attempt to feed or attract bears.
Bears near your home
In wilderness settings bears usually avoid people. But food attractants near homes can cause them to grow habituated to humans and disturbances, such as dogs and other noises. Bears are attracted by bird feeders, garbage, outdoor pet food, compost piles, fruit trees, and berry-producing shrubs.
If you see a bear on your property you can either leave the bear alone and wait for it to leave or make loud noises from a safe distance to attempt to scare the bear away.
Bears seen while hiking or camping
Black bear attacks on humans are exceptionally rare. In most hiking areas, bears normally leave once they have sensed a human. However, at campsites and campgrounds bears can be attracted by poorly stored food and garbage. If you see a bear when hiking or camping, make your presence known by making noise and waving your arms. If you surprise a bear at close range, walk away slowly while facing the bear. Avoid direct eye contact and do not run. Try to stay calm as you make your retreat. Black bears will sometimes "bluff charge" to within a few feet of you when they feel threatened. If this happens, stand your ground and shout at the bear. Do not climb a tree because black bears are excellent tree climbers. Make sure your dog is on a leash and under control.
Sometimes bears are attracted to food that is prepared outside. Do not cook near your tent or store food inside your tent. Instead, keep your food in a vehicle or use a rope to suspend it 10 or more feet off the ground and at least six feet away from tree trunks. Even clothes that you have cooked in should be stored out of a bear’s reach.
Bears, livestock, pets, and beehives
Bears occasionally attack livestock and damage beehives. Livestock can be protected with electric fencing or by moving them into a secure building at night. Store livestock and pet foods in airtight containers and clean up any spilled feed. Bears may attack sheep, goats, pigs, fowl, and llamas. Attacks on horses and cattle are less common. Bears rarely harm cats or dogs. However, they will go after pet rabbits in outdoor hutches. Beehives also can be protected with electric fencing or with reinforced wire and metal strapping.
