The U.S. Forest Service issued a warning for hikers to take precautions when visiting the Joyce Kilmer-Slickrock Wilderness inside the national forest. The area is about 110 miles southwest of downtown Asheville.
Bear attack is an attack by any mammal of the family Ursidae, on another animal, although it usually refers to bears attacking humans or domestic pets. Bear attacks are of particular concern for those who are in bear habitats. They can be fatal and often hikers, hunters, fishers, and others in bear country take precautions against bear attacks.
Stephen Herrero, a Canadian biologist, reports that during the 1990s, bears killed around three people a year in the U.S. and Canada, as compared to the 15 people killed every year by dogs. These numbers are averages over the entire U.S. population, most of whom do not live in bear habitats; for those who do, the risk of a lethal bear attack is much higher.
The forest service says it has received "reports of increased bear encounters" at four spots: Haoe Lead Trail TR53, Stratton Bald Trail TR54, Hangover Lead Trail TR56 and Hangover Trail TR56A.
"Encounters include bears stealing food and backpacks," the forest service said.
"The bears will often stay in the area of the incident for multiple hours, possibly days, depending on availability of food sources. This time of the year black bears are opportunistically looking for food that campers and trail users bring on their trips."
An increasing number of black bear encounters lead the U.S. Forest Service to issue a warning for hikers visiting the Joyce Kilmer-Slickrock Wilderness inside Nantahala National Forest on Friday. No injuries have been reported, but wildlife experts urge visitors to avoid bears and take appropriate precautions.
"Encounters include bears stealing food and backpacks," the North Carolina arm of the Forest Service wrote on Facebook. "The bears will often stay in the area of the incident for multiple hours, possibly days, depending on availability of food sources. This time of the year black bears are opportunistically looking for food that campers and trail users bring on their trips."
- Hikers on the popular Hangover and Stratton Bald trails should be particularly careful.
- While black bear attacks on people are rare, such attacks have resulted in human fatalities.
- The Forest Service recommends doing the following to prevent run-ins with bears:
- Do not store food in tents.
- Properly store food and scented items like toothpaste by using a bear-proof container.
- Clean up food or garbage around areas of your campsite.
- Do not leave food unattended.
- Keep your dog on a leash in areas where bears are reported.
If you do encounter a bear, never run away from it. Instead, back away slowly and make lots of noise. Attempt to scare the animal away with loud shouts, by banging pans together, or throwing rocks and sticks at it. And remember, seeing a wild bear in its natural environment is a very special experience.
Causes Almost all recorded bear attacks in the wild have resulted from the human surprising the bear. Hunters are the people most at risk of bear attacks because, as Tom Smith, a U.S. Geographical Survey research biologist, describes, 'Hunters typically aren't making any noise, and they sleuth around while wearing camo.' Hunters try to be silent and, though many hunters wear reflective clothing so as not to become targets for other hunters, they try to hide their movements so as not to startle game. Most bear attacks result from hunters suddenly appearing in front of them, startling a bear into an instinctive act of aggression. A bear's first reaction upon detecting a human is to run away. Fergus lists a few possible causes for this instinctive reaction, each a speculation or theory based more on intuition rather than physical evidence. Some speculate that bears inherit their cautious nature from thousands of years ago when they had to be wary of larger and more dangerous carnivores. Some believe that bears have come to relate a human presence to firearms, or other weaponry, that they have come to fear. Still others think that hunters tend to target more aggressive bears, thus leaving only the more shy and timid bears to reproduce, creating a population of bears less hostile than before.
One of the most dangerous situations that leads to bear attacks is when a bear perceives a threat to her offspring who are very protective of their young, devoting, on their own without any participation of the male bear, many years of their lives just to raise their cubs and teach them to hunt, hence the term 'mama bear' to refer to extremely reactive and protective mothers of humans, particularly those who do this without paternal care. While solo bears will usually retreat, a mother bear protecting her cubs is mostly likely to attack any sudden threat. Black bears present something of an exception to this, however, as mother black bears sometimes urge their cubs to climb trees for safety instead of remaining on the ground to protect their young.
Hunger Another dangerous situation is when a human is faced with a hungry bear that has lost its natural fear of humans. With the decrease of hunting grounds and food crops such as berries and bark, bears often become more desperate and aggressive. However, this hunger has also triggered an unexpected reaction: bears began to follow gunfire because they associate it with dead animals that they can eat.
Once a bear claims an animal carcass, it becomes very protective of its kill. This becomes a problem when a bear claims a hunter's kill, as the hunter may not wish to kill the bear as well. By avoiding a bear over a carcass, the risk of attack is reduced by around fifty percent.
Predatory Bears may act aggressively toward humans, even when they are not hungry, protecting a kill, or protecting their young. Most fatal attacks by black bears have been judged as predatory. Bear researcher Stephen Herrero determined that in black bear attacks, the bear acted as a predator in 88 per cent of fatal incidents.
American black bears American black bears are abundant in much of North America. In the US and Canada, there were between 10 and 200,000 black bears in most states or provinces as of a 1996 count. In 1996, it was estimated that there were between 735,000 and 941,000 black bears in the United States and Canada combined. Only seven states and one province had none.
Damage done by a black bear to a car door in Yosemite Valley Unlike grizzly bears, which became a subject of fearsome legend among the European settlers of North America, black bears were rarely considered overly dangerous, even though they lived in areas where the pioneers had settled. Black bears rarely attack when confronted by humans, and usually limit themselves to making mock charges, emitting blowing noises and swatting the ground with their forepaws.
According to Stephen Herrero in his Bear Attacks: Their Causes and Avoidance, 23 people were killed by black bears from 1900 to 1980. The number of black bear attacks on humans is higher than those of brown bears, though this is largely because black bears outnumber brown bears rather than being more aggressive. Compared to brown bear attacks, violent encounters with black bears rarely lead to serious injury and death. However, the majority of black bear attacks tend to be motivated by hunger rather than territoriality, and thus victims have a higher probability of surviving by fighting back rather than submitting. Unlike grizzlies, female black bears do not display the same level of protectiveness to their cubs, and will seldom attack humans in their vicinity.
The worst recorded fatality incident occurred in May 1978, in which a black bear killed three teenagers fishing in Algonquin Park in Canada. The majority of attacks happened in national parks, usually near campgrounds, where the bears had become habituated to human contact and food. Between 1964 and 1976 in the Great Smoky Mountains National Park, there were 1,028 documented incidents of black bears acting aggressively toward people, 107 of which resulted in injury. These incidents occurred mainly in tourist hotspots, where people regularly fed the bears handouts.
Asian black bears
An Asian black bear, shot after charging the 'Old Shekarr'y, as illustrated in Wild sports of the world: a boy's book of natural history and adventure Though usually shy and cautious animals, Asian black bears are more aggressive toward humans than the brown bears of Eurasia. According to Brigadier General R.G. Burton:
The Himalayan black bear is a savage animal, sometimes attacking without provocation, and inflicting horrible wounds, attacking generally the head and face with their claws, while using their teeth also on a prostrate victim. It is not uncommon to see men who have been terribly mutilated, some having the scalp torn from the head, and many sportsmen have been killed by these bears.
—?A Book of Man Eaters, Chapter XVII Bears E. T. Vere of Srinagar, Kashmir wrote of how his hospital received dozens of black bear victims annually. He wrote that, when attacking humans, black bears will rear up on their hind legs and knock victims over with their paws. They then make one or two bites on an arm or leg and finish with a snap to the head, this being the most dangerous part of the attack. There are no records of predation on humans by Asiatic black bears in Russia and no conflicts have been documented in Taiwan. However, in India, attacks on humans have been increasing yearly and have occurred largely in the northwestern and western Himalayan region. In the Chamba District of Himachal Pradesh, the number of black bear attacks on humans has gradually increased from 10 in 1988–89 to 21 in 1991–92.
Recent bear attacks on humans have been reported from Junbesi and Langtang National Park in Nepal, and occurred in villages as well as in the surrounding forest. Li Guoxing, the second person in history to have received a facial transplant, was a victim of a black bear attack. Nine people were killed by black bears in Japan between 1979 and 1989, and more recently, in September 2009, it was reported that a black bear attacked a group of tourists, seriously injuring four, while they were waiting at a bus station in the built-up area of Takayama, Gifu in central Japan. The majority of attacks tend to occur when black bears are encountered suddenly, and at close quarters. Because of this, black bears are generally considered more dangerous than sympatric brown bears, which live in more open spaces and are thus less likely to be surprised by approaching humans. They are also likely to attack when protecting food.
Illustration of a brown bear attacking Russian hunters As a rule, brown bears seldom attack humans on sight, and usually avoid people. They are, however, unpredictable in temperament, and will attack if they are surprised or feel threatened. Sows with cubs account for the majority of injuries and fatalities in North America. Habituated or food conditioned bears can also be dangerous, as their long-term exposure to humans causes them to lose their natural shyness, and in some cases associate humans with food. Small parties of one or two people are more often attacked than large groups, with no attacks being recorded against parties of more than seven people. In contrast to injuries caused by American black bears, which are usually minor, brown bear attacks tend to result in serious injury and in some cases death. In the majority of attacks resulting in injury, brown bears precede the attack with a growl or huffing sound, and seem to confront humans as they would when fighting other bears: they rise up on their hind legs, and attempt to 'disarm' their victims by biting and holding on to the lower jaw to avoid being bitten in turn. Such a bite can be more severe than that of a tiger, and has been known to crush the heads of some human victims.
Most attacks occur in the months of July, August and September, the time when the number of outdoor recreationalists, such as hikers or hunters, is higher. People who assert their presence through noises tend to be less vulnerable, as they alert bears to their presence. In direct confrontations, people who run are statistically more likely to be attacked than those who stand their ground. Violent encounters with brown bears usually last only a few minutes, though they can be prolonged if the victims fight back.
Attacks on humans are considered extremely rare in the former Soviet Union, though exceptions exist in districts where they are not pursued by hunters. East Siberian brown bears for example tend to be much bolder toward humans than their shyer, more frequently hunted European counterparts. In 2008, a platinum mining compound in the Olyotorsky district of northern Kamchatka was besieged by a group of 30 Kamchatka brown bears that killed two guards and prevented workers from leaving their homes. In Scandinavia, only three fatal attacks were recorded in the 20th century. Due to increasing brown bear population in Turkey, attacks still occur in mountainous areas of Northeastern Turkey.
Native American tribes whose territories overlapped with those of grizzly bears often viewed them with a mixture of awe and fear. North American brown bears were so feared by the Natives that they were rarely hunted, especially alone. When Natives hunted grizzlies, the act was done with the same preparation and ceremoniality as intertribal warfare, and was never done except with a company of 4 to 10 warriors. The tribe members who dealt the killing blow were highly esteemed among their compatriots. Californian Indians actively avoided prime bear habitat, and would not allow their young men to hunt alone, for fear of bear attacks. During the Spanish colonial period, some tribes, instead of hunting grizzlies themselves, would seek aid from European colonists to deal with problem bears. Many authors in the American west wrote of Natives or voyagers with lacerated faces and missing noses or eyes due to attacks from grizzlies. Within Yellowstone National Park, injuries caused by grizzly attacks in developed areas averaged approximately 1 per year during the 1930s through the 1950s, though it increased to 4 per year during the 1960s. They then decreased to 1 injury every 2 years during the 1970s. Between 1980–2002, there were only 2 grizzly bear-caused human injuries in a developed area. However, although grizzly attacks were rare in the back-country before 1970, the number of attacks increased to an average of approximately 1 per year during the 1970s, 1980s, and 1990s.
According to bear biologist Charles Jonkel, one reason for bear attacks is the lack of important foods such as huckleberry, buffalo berry, and white-bark pine nut. Winter freezes may be one reason for the food shortages.
Polar bears Polar bears particularly starving adult males will hunt humans for food, though attacks on humans by female bears is rare. Between 1870 and 2014, out of 73 recorded polar bear attacks there were 20 human fatalities and 69 injuries. Polar bears are often judged as the predators in these interactions as nearly all recorded attacks happened to groups of at least two people.
A Polar bear killed one and injured four others on 5 August 2011 in the Norwegian archipelago of Svalbard when it attacked a party of university students camped near the Von Post glacier, some 25 miles from the settlement of Longyearbyen.
Sloth bears In some areas of India and Burma, sloth bears are more feared than tigers, due to their unpredictable temperament. In Madhya Pradesh, sloth bear attacks accounted for the deaths of 48 people and the injuring of 686 others between the years 1989 and 1994, probably due in part to the density of population and competition for food sources. One specimen, known as the sloth bear of Mysore, was single-handedly responsible for the deaths of 12 people and the mutilation of 2 dozen others before being shot by Kenneth Anderson. Sloth bears defend themselves when surprised, with the majority of confrontations occurring at night. They typically charge on all fours with their head held low, before rearing on their hind legs and striking at their attackers with their claws and teeth.
History of human–bear relationships

Bear bells for the sightseers in Goshiki-numa, Japan According to Wild Bears of the Worlds, by Paul Ward and Suzanne Kynaston, human contact with bears has existed since the time of the Neanderthals and the European cave bear around 200,000 to 75,000 years ago. There is some evidence of cave bear worship during these early years: between the years 1917 and 1922, Emil Bachler discovered a large stone chest filled with cave bear skulls in the Drachenloch Cave in Switzerland, one of the Wildkirchli; between 1916 and 1922, Konrad Hormann found narrow niches filled with five cave bear skulls.
Ward and Kynaston go on to report that Cro-Magnon humans, who first appeared nearly 35,000 years ago, show more obvious evidence of cave bear worship in the forms of paintings, sculptures, and engravings; however, there is still some doubt as to whether these works specifically depict the cave bear or the European brown bear.
In the 1900s, bear populations had been decreasing because of increased hunting of bears for sustenance and for trophy prizes. Polar bear skins became popular as a sign of wealth and prestige, especially in Europe during the Victorian era. Comparatively, the pelts of giant panda, were also highly valued, priced at around 176,000 U.S. dollars. Settlers, indigenous, villagers and farmers defended their families and livestock by killing the local predators, including bears. This practice is still in place where necessary and legal.
More recently, laws have been instated to protect the dwindling populations of bears; however, as stated in Return of the Grizzly by David Whitman, these laws have increased the tensions between bears and humans. While this allows bear populations to recuperate, it also prevents people from killing bears that have invaded their property and killed their livestock.
Natural weapons and armor The various species of bear are well-developed for survival, both for attaining food and defending against predators, including unarmed humans. The different species all have the same general physical characteristics and senses that allow them to adapt to situations that threaten their survival.
Fur A bear's fur is often very thick, and it can function much like armor. In situations between bears and other predators, such as humans, this thick fur acts with the bear's thick skin and layers of fat as a buffer against most physical attacks, sometimes buffering to some extent even against firearms. According to Charles Fergus' Wild Guide: Bears, bear fur is also a source of insulation that allows bears to inhabit almost any habitat, from the hot jungles inhabited by sun bears and sloth bears to the frozen tundra inhabited by polar bears, thus occupying most of the same territory as humanity.
Muscle A bear's muscular structure is highly suited for strength and power. Polar bears are known to swim for kilometers in search of food and to scoop 200 kg seals out of the water.
Grizzly bears can bring down prey, such as bison or moose, that outweigh the bear by several hundred kilograms and can steal kills from entire packs of wolves. Their top speed running on all fours has been reported to be around 60 km/h ; comparatively, Usain Bolt ran at a record-breaking speed of 43 km/h at the 2008 Summer Olympics. Most people are incapable of reaching speeds even remotely close to this number; thus, it is impossible for a human to outrun a bear.
Claws and pawprints of an American black bear and brown bear Bears have five digits on each dextrous paw, each digit with a long non-retractable claw. The shape of the claw differs between the bear species: black bear claws are strong and curved, which allows them to claw at tree bark; grizzly bear claws are long and straight, ideal for digging, and can be up to 15 cm long; polar bear claws are thick and sharp for holding the slippery skins of seals.
Jaws The jaws of a bear reflect its omnivorous eating habits. A bear has forty-two teeth, with canines, which can be even longer than those of a tiger. While a bear's canines can pierce flesh and tear meat, a bear's back teeth are relatively flat, better suited for eating plants rather than meat. However, the jaws of bears are controlled by large muscles that are capable of crushing bones, which gives access to the nutritious marrow within. Some grizzly bears have jaws that can bite through 15-centimetre-thick pine trees.
Humans in contrast have thirty-two teeth, sixteen on each jaw, each tooth less than a half-inch long. Of these teeth, there are four incisors, two canines, four premolars, and six molars. While human incisors are capable of biting into meat, bears have more powerful jaw muscles, which make their bite more destructive to flesh. More appropriate comparisons to bear dentition are to those of dogs whose teeth are similar in proportion to those of bears .
Other senses and characteristics Bears' senses are likely similar to those of dogs, animals that at times have much the same build and dietary habits of bears.
Bears' sense of smell is dependent on a Jacobson's organ, or vomeronasal organ, which allows the bear to easily detect airborne scents. Bears use this sense of smell not only to hunt, but to detect other bears as well; male bears use smell to stay away from other male bears and to find female bears during mating season. While humans have a sense of olfaction, or smell, and they do use it for communication; its usual range is around 10 square centimeters as compared to a polar bear that can smell a seal from 32 kilometres away.
Little is known about a bear's hearing, but scientists concluded that it is at least as good as a human's. Some scientists believe that bears may even be able to detect ultrasonic sounds as well.
Natural observers believe that most bear species are near-sighted, which allows bears to forage for small objects such as berries. However, bears are also capable of discerning faraway movements, helping them hunt prey. The Kodiak bear, when compared to other species, appears to have vision comparable to a human . Experiments show that black bears can see color, unlike many mammals. With scientists still working to determine exactly how perceptive bear eyes are, it is difficult to compare bear eyesight with human eyesight.
Recovery from bear attacks Aside from the large lacerations, fractures, and other wounds that can result from bear attacks, infections are also physically detrimental. A bear's mouth is full of potentially harmful bacteria, especially if the bear has been feeding on a gut pile or feces. Bear bites can result in infections common to most animal bites, including abscesses, sepsis, and even rabies. Though there is little data, what is available from bear bite statistics indicates that bears do not tend to carry many of the most well-known dangerous anaerobic bacteria strains in their normal oral flora; however, given the circumstances of most bear attacks, wound contamination from the environment is highly likely and means there is risk of tetanus and other external microbial agents.
Recovery from bear attacks depends on the extent of damage, but often involves long-term medical treatment. As shown in the medical procedure led by Professor Shuzhong Guo, extreme cases of bear attacks have resulted in plastic surgeries and even facial transplants that, while successful, may take several years to complete and are sometimes fatal.
