American black bear

The American black bear (Ursus americanus) is a medium-sized bear native to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but do leave forests in search of food. Sometimes they become attracted to human communities because of the immediate availability of food. The American black bear is the world's most common bear species.

It is listed by the International Union for Conservation of Nature (IUCN) as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear, it is one of only two of the eight modern bear species not considered by the IUCN to be globally threatened with extinction. American black bears often mark trees using their teeth and claws as a form of communication with other bears, a behavior common to many species of bears.[1]

Despite living in North America, American black bears are not closely related to brown bears and polar bears; genetic studies reveal that they split from a common ancestor 5.05 million years ago (mya).[2] American and Asian black bears are considered sister taxa and are more closely related to each other than to the other modern species of bears.[2][3] According to recent studies, the sun bear is also a relatively recent split from this lineage.[4]

A small primitive bear called Ursus abstrusus is the oldest known North American fossil member of the genus Ursus, dated to 4.95 mya.[5] This suggests that U. abstrusus may be the direct ancestor of the American black bear, which evolved in North America.[2][6] Although Wolverton and Lyman still consider U. vitabilis an "apparent precursor to modern black bears",[7] it has also been placed within U. americanus.[6]

The ancestors of American black bears and Asian black bears diverged from sun bears 4.58 mya. The American black bear then split from the Asian black bear 4.08 mya.[2][8] The earliest American black bear fossils, which were located in Port Kennedy, Pennsylvania, greatly resemble the Asian species,[9] though later specimens grew to sizes comparable to grizzly bears.[10] From the Holocene to the present, American black bears seem to have shrunk in size,[2] but this has been disputed because of problems with dating these fossil specimens.[7]

The American black bear lived during the same period as the giant and lesser short-faced bears (Arctodus simus and A. pristinus, respectively) and the Florida spectacled bear (Tremarctos floridanus). These tremarctine bears evolved from bears that had emigrated from Asia to North America 7–8 ma.[11] The giant and lesser short-faced bears are thought to have been heavily carnivorous and the Florida spectacled bear more herbivorous,[12] while the American black bears remained arboreal omnivores, like their Asian ancestors. The American black bear's generalist behavior allowed it to exploit a wider variety of foods and has been given as a reason why, of these three genera, it alone survived climate and vegetative changes through the last Ice Age while the other, more specialized North American predators became extinct. However, both Arctodus and Tremarctos had survived several other, previous ice ages. After these prehistoric ursids became extinct during the last glacial period 10,000 years ago, American black bears were probably the only bear present in much of North America until the migration of brown bears to the rest of the continent.[10]


American black bears are reproductively compatible with several other bear species and have occasionally produced hybrid offspring. According to Jack Hanna's Monkeys on the Interstate, a bear captured in Sanford, Florida, was thought to have been the offspring of an escaped female Asian black bear and a male American black bear.[13] In 1859, an American black bear and a Eurasian brown bear were bred together in the London Zoological Gardens, but the three cubs that were born died before they reached maturity. In The Variation of Animals and Plants under Domestication, Charles Darwin noted:

In the nine-year Report it is stated that the bears had been seen in the zoological gardens to couple freely, but previously to 1848 most had rarely conceived. In the reports published since this date three species have produced young (hybrids in one case), ...[14]

An American black bear shot in autumn 1986 in Michigan was thought by some to be an American black bear/grizzly bear hybrid, due to its unusually large size and its proportionately larger braincase and skull. DNA testing was unable to determine whether it was a large American black bear or a grizzly bear.[15]

Distribution and population

Historically, American black bears occupied the majority of North America's forested regions. Today, they are primarily limited to sparsely settled, forested areas.[23] American black bears currently inhabit much of their original Canadian range, though they seldom occur in the southern farmlands of Alberta, Saskatchewan and Manitoba; they have been extinct on Prince Edward Island since 1937.[24] The total Canadian black bear population is between 396,000 and 476,000,[25] based on surveys taken in the mid-1990s in seven Canadian provinces, though this estimate excludes American black bear populations in New Brunswick, the Northwest Territories, Nova Scotia and Saskatchewan. All provinces indicated stable populations of American black bears over the last decade.[23]

The current range of American black bears in the United States is constant throughout most of the northeast and within the Appalachian Mountains almost continuously from Maine to northern Georgia, the northern Midwest, the Rocky Mountain region, the West Coast and Alaska.[24] However, it becomes increasingly fragmented or absent in other regions. Despite this, American black bears in those areas seem to have expanded their range during the last decade, such as with recent sightings in Ohio[24] and southern Indiana,[26] though these probably do not yet represent stable breeding populations. Surveys taken from 35 states in the early 1990s indicate that American black bears are either stable or increasing, except in Idaho and New Mexico. The overall population of American black bears in the United States has been estimated to range between 339,000 and 465,000,[27] though this excludes populations from Alaska, Idaho, South Dakota, Texas and Wyoming, whose population sizes are unknown.[23] In the state of California, there are an estimated 25,000-35,000 American black bears, making it the largest population of the species in the contiguous United States.[28][29]

As of 1993, known Mexican black bear populations existed in four areas, though knowledge on the distribution of populations outside those areas has not been updated since 1959. Mexico is the only country where the American black bear is classified as "endangered".[23]

There have been several sightings quite far away from where the American black bear is normally found, such as Union County, North Carolina[30][31] and western Nebraska.[32]


Throughout their range, habitats preferred by American black bears have a few shared characteristics. They are often found in areas with relatively inaccessible terrain, thick understory vegetation and large quantities of edible material (especially masts). The adaptation to woodlands and thick vegetation in this species may have originally been due to the American black bear having evolved alongside larger, more aggressive bear species, such as the extinct giant short-faced bear and the still-living grizzly bear, that monopolized more open habitats [33] and the historic presence of larger predators, such as Smilodon and the American lion, that could have preyed on American black bears. Although found in the largest numbers in wild, undisturbed areas and rural regions, American black bears can adapt to surviving in some numbers in peri-urban regions, as long as they contain easily accessible foods and some vegetative coverage.[4]

In most of the contiguous United States, American black bears today are usually found in heavily vegetated mountainous areas, from 400 to 3,000 m (1,300 to 9,800 ft) in elevation. For American black bears living in the American Southwest and Mexico, habitat usually consists of stands of chaparral and pinyon juniper woods. In this region, bears occasionally move to more open areas to feed on prickly pear cactus. At least two distinct, prime habitat types are inhabited in the Southeastern United States. American black bears in the southern Appalachian Mountains survive in predominantly oak-hickory and mixed mesophytic forests. In the coastal areas of the Southeast (such as Florida, the Carolinas and Louisiana), bears inhabit a mixture of flatwoods, bays and swampy hardwood sites.

In the northeast part of the range (United States and Canada), prime habitat consists of a forest canopy of hardwoods such as beech, maple, birch and coniferous species. Corn crops and oak-hickory mast are also common sources of food in some sections of the Northeast; small, thick swampy areas provide excellent refuge cover largely in stands of white cedar. Along the Pacific coast, redwood, Sitka spruce and hemlocks predominate as overstory cover. Within these northern forest types are early successional areas important for American black bears, such as fields of brush, wet and dry meadows, high tidelands, riparian areas and a variety of mast-producing hardwood species. The spruce-fir forest dominates much of the range of the American black bear in the Rockies. Important nonforested areas here are wet meadows, riparian areas, avalanche chutes, roadsides, burns, sidehill parks and subalpine ridgetops.

In areas where human development is relatively low, such as stretches of Canada and Alaska, American black bears tend to be found more regularly in lowland regions.[33] In parts of northeastern Canada, especially Labrador, American black bears have adapted exclusively to semi-open areas that are more typical habitat in North America for brown bears (likely due to the absence here of brown and polar bears, as well as other large carnivore species).[4]


American black bears can be distinguished from brown bears by their smaller size, their less concave skull profiles, their shorter claws and the lack of a shoulder hump.

Some specimens may develop a white "crescent moon" blaze on the chest. This white blaze, which is constant in Asian black bears, occurs in only 25% of American black bears.[34]

The skulls of American black bears are broad, with narrow muzzles and large jaw hinges. In Virginia, the total length of adult bear skulls was found to average 262 to 317 mm (10.3 to 12.5 in).[33] Across its range, the greatest skull length for the species has been reportedly measured from 23.5 to 35 cm (9.3 to 13.8 in).[4] Females tend to have slenderer and more pointed faces than males. Their claws are typically black or grayish-brown. The claws are short and rounded, being thick at the base and tapering to a point. Claws from both hind and front legs are almost identical in length, though the foreclaws tend to be more sharply curved. The paws of the species are relatively large, with a rear foot length of 13.7 to 22.5 cm (5.4 to 8.9 in), which is proportionately larger than other medium-sized bear species, but much smaller than the paws of large adult brown, and especially polar, bears.[4] The soles of the feet are black or brownish and are naked, leathery and deeply wrinkled. The hind legs are relatively longer than those of Asian black bears. The vestigial tail is usually 4.8 inches (120 mm) long. The ears are small and rounded and are set well back on the head.

American black bears are highly dexterous, being capable of opening screw-top jars and manipulating door latches. They also have great physical strength. They have been known to turn over flat-shaped rocks weighing 310 to 325 pounds (141 to 147 kg) by flipping them over with a single foreleg.[35] They move in a rhythmic, sure-footed way and can run at speeds of 25 to 30 miles per hour (40 to 48 km/h).[36] American black bears have good eyesight and have been proven experimentally to be able to learn visual color discrimination tasks faster than chimpanzees and just as fast as domestic dogs. They are also capable of rapidly learning to distinguish different shapes such as small triangles, circles and squares.[37]

American black bear weight tends to vary according to age, sex, health and season. Seasonal variation in weight is very pronounced: in autumn, their pre-den weight tends to be 30% higher than in spring, when black bears emerge from their dens. American black bears on the East Coast tend to be heavier on average than those on the West Coast, although American black bears follow Bergmann's rule and bears from the Northwest are often slightly heavier than the bears from the Southeast. Adult males typically weigh between 57–250 kg (126–551 lb), while females weigh 33% less at 41–170 kg (90–375 lb).[4][38]

In the state of California, studies have indicated that the average mass is 86 kg (190 lb) in adult males and 58 kg (128 lb) in adult females.[33] Adult American black bears in Yukon Flats National Wildlife Refuge in east-central Alaska were found to average 87.3 kg (192 lb) in males and 63.4 kg (140 lb) in females, whereas on Kuiu Island in southeast Alaska (where nutritious salmon are readily available) adult American black bears averaged an estimated 115 kg (254 lb).[39][40] In Great Smoky Mountains National Park, adult males averaged 112 kg (247 lb) and adult females averaged 47 kg (104 lb) per one study.[41] In one of the largest studies on regional body mass, bears in British Columbia averaged 73.7 kg (162 lb) in 89 females and 103.1 kg (227 lb) in 243 males.[42] In Yellowstone National Park, a population study found that adult males averaged 119 kg (262 lb) and adult females averaged 67 kg (148 lb).[43] Black bears in north-central Minnesota averaged 69.9 kg (154 lb) in 163 females and 124.95 kg (275 lb) in 77 males.[44] In New York, the two sexes reportedly average 135 kg (298 lb) and 74 kg (163 lb), respectively.[45] It was found in Nevada and Lake Tahoe region that black bears closer to urban regions were significantly heavier than their arid-country dwelling counterparts, with males near urban areas averaging 138 kg (304 lb) against wild-land males which averaged 115.5 kg (255 lb) whereas peri-urban females averaged 97.9 kg (216 lb) against the average of 65.2 kg (144 lb) in wild-land ones.[46] In Waterton Lakes National Park, Alberta adults reportedly averaged 125 to 128 kg (276 to 282 lb).[47] Adults typically range from 120 to 200 cm (47 to 79 in) in head-and-body length, and 70 to 105 cm (28 to 41 in) in shoulder height. The typically small tail is 7.7–17.7 cm (3.0–7.0 in) long.[35][48][49][50] Although they are the smallest bear species in North America, large males exceed the size of other bear species, except the brown bear and the polar bear.[35]

The biggest wild American black bear ever recorded was a male from New Brunswick, shot in November 1972, that weighed 409 kg (902 lb) after it had been dressed, meaning it weighed an estimated 500 kg (1,100 lb) in life and measured 2.41 m (7.9 ft) long.[51] Another notably outsized wild American black bear, weighing in at 408 kg (899 lb) in total, was the cattle-killer shot in December 1921 on the Moqui Reservation in Arizona.[51] The record-sized American black bear from New Jersey was shot in Morris County December 2011 and scaled 376.5 kg (830 lb).[52] Even larger, the most massive American black bear recorded in Pennsylvania (one of six weighing over 363 kg (800 lb) shot in the last 15 years in the state) weighed in at 399 kg (880 lb) and was shot in November 2010 in Pike County.[53] The North American Bear Center, located in Ely, Minnesota, is home to the world's largest captive male and female American black bears. Ted, the male, weighed 431–453.5 kg (950–1,000 lb) in the fall of 2006.[54] Honey, the female, weighed 219.6 kg (484 lb) in the fall of 2007.[55]


White-furred Kermode bear

The fur is soft, with dense underfur and long, coarse, thick guard hairs.[35] The fur is not as shaggy or coarse as that of brown bears.[56] American black bear skins can be distinguished from those of Asian black bears by the lack of a white blaze on the chest and hairier footpads.[57] Despite their name, American black bears show a great deal of color variation. Individual coat colors can range from white, blonde, cinnamon, light brown or dark chocolate brown to jet black, with many intermediate variations existing. Silvery-gray American black bears with a blue luster (this is found mostly on the flanks) occur along a portion of coastal Alaska and British Columbia. White to cream-colored American black bears occur in the coastal islands and the adjacent mainland of southwestern British Columbia. Albino specimens have also been recorded.[58] Black coats tend to predominate in moist areas such as Maine, New York, Tennessee, Michigan and western Washington. Approximately 70% of all American black bears are black, though only 50% of American black bears in the Rocky Mountains are black.[35] Many American black bears in northwestern North America are cinnamon, blonde or light brown in color and thus may sometimes be mistaken for grizzly bears. Grizzly (and other types of brown) bears can be distinguished by their shoulder hump, larger size and broader, more concave skull.[59]

In his book The Great Bear Almanac, Gary Brown summarized the predominance of black or brown/blonde specimens by location:[35]

Behavior and life history

An American black bear has better eyesight and a better sense of hearing compared to humans. Their keenest sense is their sense of smell, which is about seven times greater than a domestic dog's.[60] American black bears are excellent and strong swimmers, doing so for pleasure and to feed (largely on fish). They regularly climb trees to feed, escape enemies and hibernate. Four of the eight modern bear species are habitually arboreal (the most arboreal species, the American and Asian black bears and the sun bear, being fairly closely related).[4] Their arboreal abilities tend to decline with age.[36] American black bears may be active at any time of the day or night, although they mainly forage by night. American black bears living near human habitations tend to be more extensively nocturnal and American black bears living near brown bears tend to be more extensively diurnal.[4][33] Their social behavior is somewhat similar to that of canids.[61]

American black bears tend to be territorial and non-gregarious in nature. However, at abundant food sources (i.e. spawning salmon or garbage dumps), American black bears may congregate and dominance hierarchies form, with the largest, most powerful males dominating the most fruitful feeding spots.[62] They mark their territories by rubbing their bodies against trees and clawing at the bark. Annual ranges held by mature male American black bears tend to be very large, but there is some variation. On Long Island off the coast of Washington, ranges average 5 sq mi (13 km2), whereas on the Ungava Peninsula in Canada ranges can average up to 1,000 sq mi (2,600 km2), with some male bears traveling as far as 4,349 sq mi (11,260 km2) in times of food shortages.[4][62]

American black bears may communicate with various vocal and non-vocal sounds. Tongue-clicking and grunting are the most common sounds and are made in cordial situations to conspecifics, offspring and occasionally humans. During times of fear or nervousness, bears may moan, huff or blow air. Warning sounds include jaw-clicking and lip-popping. In aggressive interactions, American black bears produce deep-throated pulsing sounds. Cubs may squeal, bawl or scream when in distress and make motor-like humming when comfortable or nursing.[63][64][65]

Reproduction and development

Sows usually produce their first litter at the age of three to five years,[36] with those living in more developed areas tending to get pregnant at younger ages.[66] The breeding period usually occurs in the June–July period, though it can extend to August in the species' northern range. The breeding period lasts for two to three months. Both sexes are promiscuous. Males try to mate with several females, but large, dominant ones may violently claim a female if another mature male comes near.[33] Sows tend to be short-tempered with their mates after copulating. The fertilized eggs undergo delayed development and do not implant in the female's womb until November. The gestation period lasts 235 days and litters are usually born in late January to early February. Litter size is between one and six cubs, typically two or three.[67] At birth, cubs weigh 280–450 g (0.62–0.99 lb) and measure 20.5 cm (8.1 in) in length. They are born with fine, gray, down-like hair and their hind quarters are underdeveloped. They typically open their eyes after 28–40 days and begin walking after five weeks. Cubs are dependent on their mother's milk for 30 weeks and will reach independence at 16–18 months. At the age of six weeks, they attain 900 g (2.0 lb), by the age of eight weeks they reach 2.5 kg (5.5 lb) and by the age of six months they weigh 18 to 27 kg (40 to 60 lb). They reach sexual maturity at the age of three years and attain their full growth at the age of five years.[36]

Longevity and mortality

The average lifespan in the wild is 18 years, though it is quite possible for wild specimens to survive for more than 23 years.[59] The record age of a wild specimen was 39 years,[68] while that in captivity was 44 years.[35] The average annual survival rate for adult American black bears is variable, ranging from 86% in Florida to 73% in Virginia and North Carolina.[33] In Minnesota, 99% of wintering adult bears were able to survive the hibernation cycle in one study.[33] Remarkably, a study of American black bears in Nevada found that the amount of annual mortality of a population of bears in wilderness areas was 0%, whereas in developed areas in the state this figure rose to 83%.[4] Survival in subadults is generally less assured. In Alaska, only 14–17% of subadult males and 30–48% of subadult females were found in a study to survive to adulthood.[33] Across the range, the estimated number of cubs who survive past their first year is 60%.[4]

With the exception of the rare confrontation with an adult brown bear or a gray wolf pack, adult American black bears are not usually subject to natural predation.[33] However, as evidenced by scats with fur inside of them and the recently discovered carcass of an adult sow with puncture marks in the skull, American black bears may occasionally have fallen, and still do fall, prey to jaguars in the southern parts of their range. In such scenarios, the big cat would have the advantage if it ambushed the bear, killing it with a crushing bite to the back of the skull.[69] American black bear cubs tend to be more vulnerable to predation than adults. Known predators of bear cubs have included bobcats, coyotes, cougars, gray wolves, brown bears and other bears of their own species.[4][33] Many of these will stealthily snatch small cubs right from under the sleeping mother. There is a single record of a golden eagle snatching a yearling cub.[4] Once out of hibernation, mother bears may be able to fight off most potential predators.[33] Even cougars will be displaced by an angry mother bear if they are discovered stalking the cubs.[70] Flooding of dens after birth may also occasionally kill newborn cubs. However, in current times, American black bear fatalities are overwhelmingly attributable to human activities. Seasonally, tens of thousands of American black bears are hunted legally across North America, with many more being illegally poached or trapped. Auto collisions also may claim many American black bear lives annually.[4][33]


Bear hibernating
Female American black bear and cubs hibernating

American black bears were once not considered true or "deep" hibernators, but because of discoveries about the metabolic changes that allow American black bears to remain dormant for months without eating, drinking, urinating or defecating, most biologists have redefined mammalian hibernation as "specialized, seasonal reduction in metabolism concurrent with scarce food and cold weather". American black bears are now considered highly efficient hibernators.[71][72] The physiology of American black bears in the wild is closely related to that of bears in captivity. Understanding the physiology of bears in the wild is vital to the bear's success in captivity.[73]

The bears enter their dens in October and November, although in the southernmost areas of their range (i.e. Florida, Mexico, the Southeastern United States), only pregnant females and mothers with yearling cubs will enter hibernation.[4] Prior to that time, they can put on up to 14 kg (30 lb) of body fat to get them through the several months during which they fast. Hibernation in American black bears typically lasts 3–8 months, depending on regional climate.[18][74]

Hibernating American black bears spend their time in hollowed-out dens in tree cavities, under logs or rocks, in banks, caves, or culverts and in shallow depressions. Although naturally-made dens are occasionally used, most dens are dug out by the bear itself.[59] Females have been shown to be pickier in their choice of dens in comparison to males.[75]

During their time in hibernation, an American black bear's heart rate drops from 40–50 beats per minute to 8 beats per minute and the metabolic rate can drop to a quarter of the bear's (non-hibernating) basal metabolic rate (BMR). These reductions in metabolic rate and heart rate do not appear to decrease the bear's ability to heal injuries during hibernation.[76]

The hibernating American black bear does not display the same rate of muscle and bone atrophy relative to other nonhibernatory animals that are subject to long periods of inactivity due to ailment or old age.[77][78] A hibernating American black bear loses approximately half the muscular strength compared to that of a well-nourished, inactive human. The bear's bone mass does not change in geometry or mineral composition during hibernation, which implies that the bear's conservation of bone mass during hibernation is due to a biological mechanism.[79] During hibernation American black bears retain all excretory waste, leading to the development of a hardened mass of fecal material in the colon known as a fecal plug.[80] A special hormone, leptin, is released into the bear's systems to suppress appetite. The retention of waste during hibernation (specifically in minerals such as calcium) may play a role in the bear's resistance to atrophy.[77]

The body temperature of the American black bear does not drop significantly, like other mammalian hibernators (staying around 35 °C (95 °F)) and they remain somewhat alert and active. If the winter is mild enough, they may wake up and forage for food. Females also give birth in February and nurture their cubs until the snow melts.[81] During winter, American black bears consume 25–40% of their body weight.[82] The footpads peel off while they sleep, making room for new tissue.

Many of the physiological changes an American black bear exhibits during hibernation are retained slightly post-hibernation. Upon exiting hibernation, bears retain a reduced heart rate and basal metabolic rate. The metabolic rate of a hibernating bear will remain at a reduced level for up to 21 days after hibernation.[83] After emerging from their winter dens in spring, they wander their home ranges for two weeks so that their metabolism accustoms itself to the activity. In mountainous areas, they seek southerly slopes at lower elevations for forage and move to northerly and easterly slopes at higher elevations as summer progresses.

Generally, American black bears are largely crepuscular in foraging activity, though they may actively feed at any time.[62] Up to 85% of the American black bear's diet consists of vegetation,[36] though they tend to dig less than brown bears, eating far fewer roots, bulbs, corms and tubers than the latter species.[58] When initially emerging from hibernation, they will seek to feed on carrion from winter-killed animals and newborn ungulates. As the spring temperature warms, American black bears seek new shoots of many plant species, especially new grasses, wetland plants and forbs.[82] Young shoots and buds from trees and shrubs during the spring period are also especially important to American black bears emerging from hibernation, as they assist in rebuilding muscle and strengthening the skeleton and are often the only digestible foods available at that time.[84] During summer, the diet largely comprises fruits, especially berries and soft masts such as buds and drupes. During the autumn hyperphagia, feeding becomes virtually the full-time task of American black bears. Hard masts become the most important part of the American black bear's diet in autumn and may even partially dictate the species' distribution. Favored masts such as hazelnuts, oak acorns and whitebark pine nuts may be consumed by the hundreds each day by a single American black bear during the fall.[4][33] During the fall period, American black bears may also habitually raid the nut caches of tree squirrels.[82] Also extremely important in fall are berries such as huckleberries and buffalo berries.[4] American black bears living in areas near human settlements or around a considerable influx of recreational human activity often come to rely on foods inadvertently provided by humans, especially during summertime. These include refuse, birdseed, agricultural products and honey from apiaries.[59]

The majority of the American black bear's animal diet consists of insects, such as bees, yellow jackets, ants and their larvae.[82] American black bears are also fond of honey and will gnaw through trees if hives are too deeply set into the trunks for them to reach them with their paws. Once the hive is breached, the bears will scrape the honeycombs together with their paws and eat them, regardless of stings from the bees.[51] American black bears that live in northern coastal regions (especially the Pacific Coast) will fish for salmon during the night, as their black fur is easily spotted by salmon in the daytime. However, the white-furred American black bears of the islands of western Canada have a 30% greater success rate in catching salmon than their black-furred counterparts.[85] Other fish, including suckers, trout and catfish, are readily caught whenever possible.[86] Although American black bears do not often engage in active predation of other large animals for much of the year, the species will regularly prey on mule and white-tailed deer fawns in spring, given the opportunity.[87][88][89] Bears may catch the scent of hiding fawns when foraging for something else and then sniff them out and pounce on them. As the fawns reach 10 days of age, they can outmaneuver the bears and their scent is soon ignored until the next year.[90] American black bears have also been recorded similarly preying on elk calves in Idaho[91] and moose calves in Alaska.[92]

American black bear predation on adult deer is rare, but has been recorded.[93][94][95] They may even hunt prey up to the size of adult female moose, which are considerably larger than themselves, by ambushing them.[96] There is at least one record of a male American black bear killing two bull elk over the course of six days by chasing them into deep snow banks, which impeded their movements. In Labrador, American black bears are exceptionally carnivorous, living largely off caribou, usually young, injured, sickly or dead specimens, and rodents such as voles. This is believed to be due to a paucity of edible plant life in this sub-Arctic region and a local lack of competing large carnivores (including other bear species).[59] Like brown bears, American black bears try to use surprise to ambush their prey and target the weak, injured, sickly or dying animals in the herds. Once a deer fawn is captured, it is frequently torn apart alive while feeding.[88] If it is able to capture a mother deer in spring, the bear frequently begins feeding on the udder of lactating females, but generally prefers meat from the viscera. American black bears often drag their prey to cover, preferring to feed in seclusion. The skin of large prey is stripped back and turned inside out, with the skeleton usually left largely intact. Unlike gray wolves and coyotes, American black bears rarely scatter the remains of their kills. Vegetation around the carcass is usually matted down by American black bears and their droppings are frequently found nearby. American black bears may attempt to cover remains of larger carcasses, though they do not do so with the same frequency as cougars and grizzly bears.[97] They will readily consume eggs and nestlings of various birds and can easily access many tree nests, even the huge nests of bald eagles.[36] American black bears have been reported stealing deer and other animals from human hunters.

Interspecific predatory relationships

Over much of their range, American black bears are assured scavengers that can intimidate, using their large size and considerable strength, and if necessary dominate other predators in confrontations over carcasses. However, on occasions where they encounter Kodiak or grizzly bears, the larger two brown subspecies dominate them. American black bears tend to escape competition from brown bears by being more active in the daytime and living in more densely forested areas. Violent interactions, resulting in the deaths of American black bears, have been recorded in Yellowstone National Park.[98][99]

American black bears do compete with cougars over carcasses. Like brown bears, they will sometimes steal kills from cougars. One study found that both bear species visited 24% of cougar kills in Yellowstone and Glacier National Parks, usurping 10% of the carcasses.[100][101] Another study found that American black bears visited 48% of cougar kills in summer in Colorado and 77% of kills in California. As a result, the cats spend more time killing and less time feeding on each kill.[102][103]

American black bear interactions with gray wolves are much rarer than with brown bears, due to differences in habitat preferences. The majority of American black bear encounters with wolves occur in the species' northern range, with no interactions being recorded in Mexico. Despite the American black bear being more powerful on a one-to-one basis, packs of wolves have been recorded to kill black bears on numerous occasions without eating them. Unlike brown bears, American black bears frequently lose against wolves in disputes over kills.[104] Wolf packs typically kill American black bears when the larger animals are in their hibernation cycle.[38]

There is at least one record of an American black bear killing a wolverine in a dispute over food in Yellowstone National Park.[105] Anecdotal cases of alligator predation on American black bears have been reported, though such cases may involve assaults on cubs.[106]

Relationships with humans

In folklore, mythology and culture

Harry Colebourne and Winnie
Harry Colebourn and Winnie, the bear from which Winnie-the-Pooh got his name

American black bears feature prominently in the stories of some of America's indigenous peoples. One tale tells of how the black bear was a creation of the Great Spirit, while the grizzly bear was created by the Evil Spirit.[107] In the mythology of the Haida, Tlingit and Tsimshian people of the Northwest Coast, mankind first learned to respect bears when a girl married the son of a black bear chieftain.[108] In Kwakiutl mythology, American black and brown bears became enemies when Grizzly Bear Woman killed Black Bear Woman for being lazy. Black Bear Woman's children, in turn, killed Grizzly Bear Woman's children.[109] The Navajo believed that the Big Black Bear was chief among the bears of the four directions surrounding Sun's house and would pray to it in order to be granted its protection during raids.[110]

Morris Michtom, the creator of the teddy bear, was inspired to make the toy when he came across a cartoon of Theodore Roosevelt refusing to shoot an American black bear cub tied to a tree.[111] The fictional character Winnie-the-Pooh was named after Winnipeg, a female American black bear cub that lived at the London Zoo from 1915 until her death in 1934.[112] An American black bear cub, who in the spring of 1950 was caught in the Capitan Gap Fire, was made into the living representative of Smokey Bear, the mascot of the United States Forest Service.[113]

Terrible Ted was a de-toothed and de-clawed American black bear who was trained to perform as a pro wrestler and whose "career" lasted from the 1950s to the 1970s.

The American black bear is the mascot of the University of Maine and Baylor University, where the university houses two live American black bears on campus.

Sleeping Bear Dunes in Michigan is named after a Native American legend, where a female bear and her cub swam across Lake Michigan. Exhausted from their journey, the bears rested on the shoreline and fell sound asleep. Over the years, the sand covered them up, creating a huge sand dune.

Attacks on humans

The incidence of bear attacks in parks and campgrounds declined after the introduction of bear-resistant garbage cans and other reforms

Although an adult bear is quite capable of killing a human, American black bears typically avoid confronting humans whenever possible. Unlike grizzly bears, which became a subject of fearsome legend among the European settlers of North America, American black bears were rarely considered overly dangerous, even though they lived in areas where the pioneers had settled. American 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. The number of American black bear attacks on humans is higher than those of the brown bear in North America, though this is largely because the American black bear considerably outnumbers the brown bear, rather than greater aggressiveness. Compared to brown bear attacks, aggressive encounters with American black bears rarely lead to serious injury. However, the majority of American 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 female brown bears, female American black bears do not display the same level of protectiveness toward their cubs and seldom attack humans when they are in the cubs' vicinity.[58] However, occasionally, attacks by protective mothers do occur.[33] The worst recorded fatality incident occurred in May 1978, in which an American black bear killed three teenagers who were fishing in Algonquin Park in Canada.[114] Another exceptional, spree-like attack occurred in August 1997 in Liard River Hot Springs Provincial Park in Canada, when an emaciated American black bear attacked a child and mother, killing the mother as well as an adult man who tried to intervene. This bear was shot while mauling a fourth victim.[115][116]

The majority of attacks happened in national parks, usually near campgrounds, where the bears had become habituated to close human proximity and food-conditioned.[58] Out of 1,028 incidents of American black bears acting aggressively toward people, recorded from 1964 to 1976 in the Great Smoky Mountains National Park, 107 resulted in injury and occurred mainly in tourist hot spots where people regularly fed the bears handouts.[114] In almost every case where open garbage dumps that had previously attracted American black bears were closed and/or handouts had ceased, the number of aggressive encounters with American black bears has decreased precipitously over time.[33] However, in the aforementioned case of the spree attack in Liard River Hot Springs, the attacking bear was believed to have been previously almost fully dependent on a local garbage dump that had closed and was starving to death as a result of the loss of that food source.[115] Attempts to relocate American black bears are typically unsuccessful, as they seem to be able to return to their home range, even without familiar landscape cues.[33]

Livestock and crop predation

A limitation of food sources in early spring and wild berry and nut crop failures during the summer months may be contributing factors to American black bears regularly feeding from commercial human-based food sources. Crops are frequently eaten by these bears, especially during autumn hyperphagia when natural foods are scarce. Favored crops may include apples, oats and corns.[4] American black bears can do extensive damage in some areas of the northwestern United States by stripping the bark from trees and feeding on the cambium. Livestock depredations by American black bears occur mostly in spring. Although American black bears have the capacity to (and occasionally do) hunt adult cattle and horses, they seem to prefer smaller, more easily overwhelmed prey such as sheep, goats, pigs and young calves. They normally kill by biting the neck and shoulders, though they may break the neck or back of the prey with blows from the paws. Evidence of a bear attack includes claw marks and is frequently found on the neck, back and shoulders of larger animals. Surplus killing of sheep and goats are common. American black bears have been known to frighten livestock herds over cliffs, causing injuries and death to many animals; whether or not this is intentional is not known.[97] Occasionally pets, especially domestic dogs, which are most prone to harass a bear, are killed by American black bears.[117] It is not recommended to use unleashed dogs as a deterrent from bear attacks. Although large, aggressive dogs can sometimes cause a bear to run, if pressed, angry bears can frequently turn the tables and end up chasing the dogs in return. A bear in pursuit of a pet dog has the potential to threaten both canid and human lives.[118][119]

In British Columbia, a group of American black bears were used as guard animals to protect a marijuana plantation.[120][121][122]

Hunting and exploitation


Historically, American black bears were hunted by both Native Americans and European settlers. Some Native American tribes, in admiration for the American black bear's intelligence, would decorate the heads of bears they killed with trinkets and place them on blankets. Tobacco smoke would be wafted into the disembodied head's nostrils by the hunter that dealt the killing blow, who would compliment the animal for its courage.[51] The Kutchin typically hunted American black bears during their hibernation cycle. Unlike the hunting of hibernating grizzly bears, which was fraught with danger, hibernating American black bears took longer to awaken and hunting them was thus safer and easier.[123] During the European colonisation of eastern North America, thousands of American black bears were hunted for their meat, fat and fur.[3] Theodore Roosevelt wrote extensively on American black bear hunting in his Hunting the Grisly and other sketches, in which he stated,

in [a black bear] chase there is much excitement, and occasionally a slight spice of danger, just enough to render it attractive; so it has always been eagerly followed.


He wrote that American black bears were difficult to hunt by stalking, due to their habitat preferences, though they were easy to trap. Roosevelt described how, in the southern states, planters regularly hunted American black bears on horseback with hounds. General Wade Hampton was known to have been present at 500 successful American black bear hunts, two-thirds of which he killed personally. He killed 30 or 40 American black bears with only a knife, which he would use to stab the bears between the shoulder blades while they were distracted by his hounds.[96] Unless well trained, horses were often useless in American black bear hunts, as they often bolted when the bears stood their ground.[51] In 1799, 192,000 American black bear skins were exported from Quebec. In 1822, 3,000 skins were exported from the Hudson's Bay Company.[124] In 1992, untanned, fleshed and salted American black bear hides were sold for an average of $165.[125]

In Canada, American black bears are considered as both a big game and furbearer species in all provinces, save for New Brunswick and the Northwest Territories, where they are only classed as a big game species. There are around 80,900 licensed American black bear hunters in all of Canada. Canadian black bear hunts take place in the fall and spring and both male and female bears can be legally taken, though some provinces prohibit the hunting of females with cubs, or yearling specimens.[23]

Currently, 28 of the U.S. states have American black bear hunting seasons. 19 states require a bear hunting license, with some also requiring a big game license. In eight states, only a big game license is required to hunt American black bears. Overall, over 481,500 American black bear hunting licences are sold per year. The hunting methods and seasons vary greatly according to state, with some bear hunting seasons including fall only, spring and fall, or year-round. New Jersey, in November 2010, approved a six-day bear-hunting season in early December 2010 to slow the growth of the American black bear population. Bear hunting had been banned in New Jersey for five years before that time.[126] A Fairleigh Dickinson University PublicMind poll found that 53% of New Jersey voters approved of the new season if scientists concluded that American black bears were leaving their usual habitats and destroying private property.[127] Men, older voters and those living in rural areas were more likely to approve of a bear-hunting season in New Jersey than women, younger voters and those living in more developed parts of the state.[127] In the western states, where there are large American black bear populations, there are spring and year-round seasons. Approximately 18,000 American black bears were killed annually in the U.S. between 1988 and 1992. Within this period, annual kills ranged from six bears in South Carolina to 2,232 in Maine.[23]

According to Dwight Schuh in his Bowhunter's Encyclopedia, American black bears are the third most popular quarry of bowhunters, behind deer and elk.[128]


American black bear meat had historically been held in high esteem among North America's indigenous people and colonists.[51] American black bears were the only bear species the Kutchin hunted for their meat, though this constituted only a small part of their diet.[123] According to the second volume of Frank Forester's Field Sports of the United States, and British Provinces, of North America:

The flesh of the [black] bear is savoury, but rather luscious, and tastes not unlike pork. It was once so common an article of food in New-York as to have given the name of Bear Market to one of the principal markets of the city.

— Frank Forester's Field Sports of the United States, and British Provinces, of North America p. 186

Theodore Roosevelt himself likened the flesh of young American black bears to that of pork and not as coarse or flavourless as the meat of grizzly bears.[129] The most favoured cuts of the American black bear's meat are concentrated in the legs and loins. Meat from the neck, front legs and shoulders is usually ground into minced meat, or used for stews and casseroles. Keeping the fat on tends to give the meat a strong flavour. As American black bears can have trichinellosis, cooking temperatures need to be high in order to kill the parasites.[130]

American black bear fat was once valued as a cosmetic article that promoted hair growth and gloss. The fat most favoured for this purpose was the hard white fat found in the body's interior. As only a small portion of this fat could be harvested for this purpose, the oil was often mixed with large quantities of hog lard.[51] However, animal rights activism over the last decade has slowed the harvest of these animals; therefore the lard from American black bears has not been used in recent years for the purpose of cosmetics.

Alberta Mountain forests

The Alberta Mountain forests are a temperate coniferous forests ecoregion of Canada.


Bears are carnivoran mammals of the family Ursidae. They are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails.

While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, climbers, and swimmers. Bears use shelters, such as caves and logs, as their dens; most species occupy their dens during the winter for a long period of hibernation, up to 100 days.

Bears have been hunted since prehistoric times for their meat and fur; they have been used for bear-baiting and other forms of entertainment, such as being made to dance. With their powerful physical presence, they play a prominent role in the arts, mythology, and other cultural aspects of various human societies. In modern times, bears have come under pressure through encroachment on their habitats and illegal trade in bear parts, including the Asian bile bear market. The IUCN lists six bear species as vulnerable or endangered, and even least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing.

Blackjack Springs Wilderness

The Blackjack Springs Wilderness is a 5,800-acre (23 km2) wilderness area northeast of Eagle River, Wisconsin. It is located within the Nicolet unit of the Chequamegon-Nicolet National Forest and is administered by the US Forest Service. The area protects four large, crystal-clear springs at the headwaters of Blackjack Creek, part of the Eagle River and Wisconsin River drainage. The area was added to the National Wilderness Preservation System by Congress in 1978.

The area displays the rolling, uneven landscape caused by the Wisconsin Glacial Episode, typical of the Lake Superior highlands. The wilderness area itself contains one lake, Whispering Lake, and a number of other streams, ponds, and wetland areas. A majority of the forest is new-growth secondary forest, a result of extensive logging during the late 19th and early 20th centuries. Logging roads and railroad grades are still evident in the area.Wildlife found in the wilderness area include American black bear, white-tailed deer, ruffed grouse, various songbirds, and fisher.

The Blackjack Springs area provides opportunities for camping, hunting, hiking, canoeing, birdwatching, and fishing.

Cinnamon bear

The cinnamon bear (Ursus americanus cinnamomum) is both a highly variable color morph and a subspecies of the American black bear, native to the central and western areas of the United States and Canada. Established populations are found in Colorado, New Mexico, Utah, Idaho, Montana, Washington, Manitoba, Minnesota, Wisconsin, Wyoming, California, Alberta, and British Columbia. They also have been seen in Pennsylvania and New York. The most striking difference between a cinnamon bear and any other black bear is its brown or red-brown fur, reminiscent of cinnamon. The subspecies was given this designation because the lighter color phase is more common there than in other areas.

Fauna of California

The fauna of the State of California may be the most diverse in the United States of America. Of the Lower 48 conterminous states, California has the greatest diversity in climate, terrain and geology in general. The state's six life zones are the lower Sonoran (desert); upper Sonoran (foothill regions and some coastal lands); transition (coastal areas and moist northeastern counties); and the Canadian, Hudsonian, and Arctic zones, comprising California's highest elevations. California’s diverse geography gives rise to dozens of different ecosystems, each of which has its own unique native plants and animals. California is a huge state, the 3rd largest in the U.S., and can range broadly in habitat type.Earth scientists typically divide California into eleven distinct geomorphic provinces with clearly defined boundaries. They are, from north to south, the Klamath Mountains, the Cascade Range, the Modoc Plateau, the Basin and Range, the Coast Ranges, the Central Valley, the Sierra Nevada, the Transverse Ranges, the Mojave Desert, the Peninsular Ranges, and the Colorado Desert. Here, the Los Angeles Basin, the Channel Islands, and the Pacific Ocean are treated as distinct regions.

Common animals that live throughout all the state include raccoons, weasels, otters, beavers, hawks, lizards, owls, coyotes, skunks, snakes, cougars, black bears, deers, squirrels and whales. As of 2013, there are 634 bird species on the California Birds Records Committee, ten of which are introduced species which are not native to the state. The California quail, the official state bird, has a breeding habit of mainly shrubby areas and open woodland. Another bird which winters in California is the American white pelican which is a large seabird, with a wingspan reaching up to 110 inches (280 cm).

Venomous spiders in California include Arizona recluse, baja recluse, chilean recluse, desert recluse, martha's recluse, russell's recluse, brown widow and western black widow.

Frontenac Provincial Park

Frontenac Provincial Park is located near the town of Sydenham, north of the city of Kingston, Ontario, Canada. The Government of Ontario has classified Frontenac Provincial Park as a natural environment park. The park lies on the Frontenac Axis, a topographic extension of the Canadian Shield, which connects to the Adirondack Mountains, and consists of mixed forest, lakes, wetlands, and granite outcrops. Recreational opportunities include hiking, canoeing, and backcountry camping. Wilderness courses are offered to teach wilderness skills in a semi-wilderness setting.

Historically, the park provided important resources for local communities through the logging and mining industries.

Frontenac Provincial Park is home to a native population of grey wolves. Other animals that call the park home are American black bear, red fox, mink, northern river otter, white-tailed deer, porcupine, and fisher.

Giant hutia

The giant hutias are an extinct group of large rodents known from fossil and subfossil material in the West Indies. One species, Amblyrhiza inundata, is estimated to have weighed between 50 and 200 kg (110 and 440 lb), big specimens being as large as an American black bear. This is twice as large as the capybara, the largest rodent living today, but still much smaller than Josephoartigasia monesi, the largest rodent known. These animals were probably used as a food source by aboriginal humans. All giant hutias are in a single family, Heptaxodontidae, which contains no living species; this grouping seems to be paraphyletic and artificial, however.

One of the smaller species, Quemisia, may have survived as late as the time of the earliest Holocene.

Some of their smaller relatives from the family Capromyidae, known as hutias, survive in the Caribbean Islands.

Kermode bear

The Kermode bear (Ursus americanus kermodei), also known as the spirit bear (particularly in British Columbia), is a rare subspecies of the American black bear living in the Central and North Coast regions of British Columbia, Canada. It is the official provincial mammal of British Columbia. While most Kermode bears are black, there are between 100 and 500 fully white individuals. The white variant is most common on three islands in British Columbia (Gribbell, Princess Royal, and Roderick), where 10–20% of bears are white. Kermode bears hold a prominent place in the oral traditions of the indigenous peoples of the area. They have also been featured in a National Geographic documentary.

List of U.S. state mammals

A state mammal is the official mammal of a U.S. state as designated by a state's legislature. Many states also have separately officially designated state animals, state birds, state fish, state butterflies, and state reptiles. States similarly have state flowers, state trees and state songs.

Louisiana black bear

The Louisiana black bear (Ursus americanus luteolus), one of 16 subspecies of the American black bear, is found in parts of Louisiana, mainly along the Mississippi River Valley and the Atchafalaya River Basin. It was classified as 'threatened' under the U.S. Endangered Species Act from 1992-2016.

The validity of this subspecies has been repeatedly debated.

Pedals (bear)

Pedals (died October 2016, New Jersey, United States) was an American black bear (Ursus americanus) that walked upright on its hind legs due to injuries on his front paws. After videos of the bear were posted on the internet, more than 300,000 people signed a petition to move the bear to a wildlife sanctuary. Pedals appears to have been killed in October 2016 in New Jersey's first sanctioned bow and arrow hunt in four decades. During the hunt, which also included muzzle-loading rifles, a total of 562 bears were killed.

Pocksha Pond

Pocksha Pond is a lake/reservoir/pond within the towns of Lakeville and Middleboro, in southeastern Massachusetts. It shares its waters with Great Quittacas Pond and openly connected with Assawompset Pond. These lakes provides a source of drinking water to the city of New Bedford, the largest city in southeastern Massachusetts.

Spirit bear

Spirit bear refers to any white-coated (leucistic) American black bear. It also specifically refers to the Kermode bear, a subspecies of American black bear in coastal British Columbia, which has a high prevalence of white-coated bears.

It can also refer to:

Ursid hybrid

An ursid hybrid is an animal with parents from two different species or subspecies of the Ursidae (bear) family. Species and subspecies of bear known to have produced offspring with another bear species or subspecies include brown bears, black bears, grizzly bears and polar bears, all of which are members of the Ursus genus. Bears not included in Ursus, such as the giant panda, are probably unable to produce hybrids. Note all of the confirmed hybrids listed here have been in captivity (except grizzly/polar bear), but there have been hybrids in the wild.

A recent study found genetic evidence of multiple instances and species combinations where genetic material has passed the species boundary in bears (a process called introgression by geneticists). Specifically, species with evidence of past intermingling were (1) brown bear and American black bear, (2) brown bear and polar bear, (3) American black bear and Asian black bear, (4) bears currently distributed in Asia (sloth bear, sun bear and Asian black bear). Overall, this study shows that evolution in the bear family (Ursidae) has not been strictly bifurcating, but instead showed complex evolutionary relationships.

Ursus (genus)

Ursus is a genus in the family Ursidae (bears) that includes the widely distributed brown bears, the polar bear, black bears and Ursus thibetanus, the

Asiatic black bear. The name is derived from the Latin ursus, meaning bear.

Ursus americanus carlottae

The Haida Gwaii black bear (Ursus americanus carlottae) is a morphologically distinct subspecies of the American black bear. The most significant morphological differences are its large size, massive cranium and large molars. This subspecies is endemic to the Haida Gwaii (the Queen Charlotte Islands) and is considered a "keystone species" because of the bears' transportation of salmon remains into the surrounding forests of the Haida Gwaii.

West Virginia Black Bears

The West Virginia Black Bears are a Minor League Baseball team based in Granville, West Virginia. The team began play in the New York–Penn League in 2015 as an affiliate of the Pittsburgh Pirates. The team is owned by Bob Rich, Jr. and plays at Monongalia County Ballpark, which is across the Monongahela River from Morgantown and West Virginia University.

In August 2014, it was announced that the Jamestown Jammers would cease operations and move to Morgantown. On October 22, the team announced that they would be named the "Black Bears" following a fan vote, as the American black bear is the state animal of West Virginia. Other finalists included Black Diamonds, Canaries, Coal Kings, Coal Sox, Energy, Moonshiners, Muskets, Wild Ones, and Wonder.In January 2015, Wyatt Toregas was named as their inaugural manager. The Black Bears won the New York–Penn League wild card in their inaugural season. The team then defeated the Williamsport Crosscutters and the Staten Island Yankees to win the 2015 New York–Penn League Championship.

Wildcat Hill Provincial Park

Wildcat Hill Provincial Park is a wilderness park in northeastern Saskatchewan approximately 40km from Hudson Bay. It is located amongst the Pasqua Hills, south of Highway 55, and west of Highway 9. The 21,752-hectare park was established as a protected area in 1971, and became a Provincial Park in 1992.The main attractions of Wildcat Hill Provincial Park are hunting and snowmobiling. The snowmobile trails in the park are part of a 684.14km-network of trails maintained by the Hudson Bay Trail Riders. In addition to the groomed trails, there are also many kilometres of unmaintained trails.

Moose, white-tailed deer, wolves, american black bear, coyotes and cougar are commonly found inside the park. In addition to hunting, fishing can be done in the park at Bankside Lake, Firhead Lake, the Fir River and the Pasquia River.
