The most commonly eaten kinds of plants are fleshy roots, fruits, berries, grasses, and forbs. If grizzly bears are on the hunt, their prey can include fish especially salmon , rodents like ground squirrels, carrion, and hoofed animals like moose , elk, caribou, and deer. They are especially good at catching the young of these hoofed species. Grizzly bears can also target domestic animals like cattle and sheep and cause economically important losses for some ranchers.

The National Wildlife Federation has a program on National Forest lands surrounding Yellowstone Park to prevent attacks on domestic livestock by purchasing the grazing allotments from ranchers. Grizzly bears use sounds, movement, and smells to communicate. They growl, moan, or grunt, especially when females are communicating with their young or during mating season when male bears can fight each other fiercely for the opportunity to mate with receptive females.

Grizzly bears also rub their bodies on trees to scratch and to let other bears know they are there. Winter can be very tough for many species of wildlife, because the season brings harsh weather and little food. Grizzly bears hibernate in warm dens during the winter to minimize energy expenditure at a time when natural foods are not available and to permit their tiny young to be born in a warm and secure environment. Throughout the summer and autumn, grizzly bears build up fat reserves by consuming as much food as they can find.

In late fall or winter, the bears find a hillside and dig a hole to serve as their winter den. When inside the den, grizzly bears slow down their heart rate, reduce their temperature and metabolic activity, and live off stored fat reserves. Pregnant females give birth in the dens and nurse their cubs until they are large enough to venture outside in the spring as snow melts and new food become available. Depending on the length of the winter season, grizzly bears can stay in their dens for up to seven months.

Grizzly bear hibernation is not as deep of a sleep as some other hibernators, like bats or ground squirrels, and they will quickly wake up when disturbed. Females with newborn cubs are the last to leave their dens in the spring. Females with older cubs emerge earlier and solitary females and males are the first to exit dens in the spring. Pregnant females are the first to enter dens in the fall followed by females with cubs; solitary males enter dens the latest.

Grizzly bears begin to look for mates in the spring and early summer. Females can mate with more than one male during her breeding season. If a female bear is unable to gain enough weight during the summer and fall, her body will tell her to not proceed with the pregnancy and the embryo will reabsorb. Current Population Trend: Stable.

They can be dangerous to humans, particularly if surprised or if humans come between a mother and her cubs. Grizzlies once lived in much of western North America and even roamed the Great Plains. These animals need a lot of space—their home range can encompass up to square miles —so their ideal habitat is one that is isolated from development and has plenty of food and places to dig their dens.

Though European settlement gradually eliminated the bears from much of their original habitat, grizzly populations can still be found in parts of Wyoming, Montana, Idaho, and Washington State.

Many grizzlies also still roam the wilds of Canada and Alaska, where hunters pursue them as big game trophies. At its peak, the grizzly population numbered more than 50, Aggressive hunting in the early 20th century also threatened the survival of the grizzly bear. By the s and s, these bears had been reduced to less than 2 percent of their historical range.

In the s, it was estimated that there were only to remaining in the wild. In , grizzly bears were listed as threatened under the U. Endangered Species Act. Today, grizzlies are considered a conservation success story.

Ever since they gained protections under the U. Endangered Species Act, the population of grizzly bears has grown. The U. Fish and Wildlife Service established recovery zones for the bears and set out to improve relationships between humans and bears by educating the public about these animals and establishing programs to reimburse ranchers for livestock bears killed. Now there are more than five times the number of grizzlies than there were in —and about 1, to 1, in the contiguous U.

While the U. Fish and Wildlife Service has tried to delist grizzly bears twice, both attempts have been blocked. They are wide-ranging but may congregate in areas with abundant food. Grizzly bears are opportunistic omnivores with high diet variability among individuals, seasons, and years. Grizzly bears once occurred in most of Washington, but are now restricted to remote areas of the Selkirk Mountains and certain places near the northern border of Washington between these two ecosystems.

These areas support the best remaining seclusion habitat in the state. Washington’s total grizzly bear population is small, and is likely the periphery or periodic expansion area from populations in British Columbia and Idaho.

Trends in the North Cascades and Selkirk populations are unknown. Grizzlies have not been documented in the North Cascades since October Recent survey data indicates the Selkirk grizzly bear population is slowly increasing. For a map of conservation status of the western population of grizzly bear and a map of global geographic range, see NatureServe Explorer and the International Union for Conservation of Nature Red List.

Grizzly bears are considered a highly adaptable species and are dietary generalists, feeding on a variety of food items, which may decrease the overall sensitivity of this species. Altered fire regimes may remove important habitat, but could also open up new areas. See the Climate vulnerability section for information about the threats posed by climate change to grizzly bear.

Carry bear spray and know how to use it: Carry your bear spray in a readily accessible location like in a belt holster, not in your backpack. If you do inadvertently encounter a bear, you should remain calm, move slowly, and attempt to leave the area immediately. If a bear charges you, responsible use of bear spray is the best way to deter an attack. Video by: Interagency Grizzly Bear Committee. Pack smart: Avoid bringing smelly foods, like bacon or tuna, or scented toiletries. Dry, sealed foods are lighter and less aromatic.

Bears have an excellent sense of smell, so bring at least 30 feet of rope, storage bags, and carabiners for hanging food. Use bear-resistant containers: A good method for storing food and other smelly items that attract bears, these containers can be purchased or rented from outdoor shops.

Coolers, backpacks, wooden boxes, and tents are NOT bear resistant! Be alert: Learn to recognize and watch for signs of bears in the area, like tracks, scat, and diggings. Use binoculars to scan the areas ahead. After maturing, male grizzlies move far off to establish their own territories. On the other hand, female grizzlies establish their territories not far away from their mother. Female grizzlies give birth during the denning period.

Of all mammals, grizzly bears have the slowest reproductive rate. The females attain sexual maturity at age five. The mating season among grizzly bears falls between May and July. The female bodies will however permit egg implantation in the months of October or November. The period in between breeding and egg implantation may allow for miscarriage as well. A female grizzly, which has not fed on enough nutrients and calories, may fail to conceive.

The cubs feed on milk from their mother and remain under care and tutelage for a period of two to three years. A female grizzly bear with cubs can easily attack other species including humans in its endeavor to protect its cubs.

Katmai National Park and Preserve is one of the best spots to view brown bears. The bear population in Katmai is estimated at a healthy 2, At Brooks Camp, a famous site exists where grizzlies can be seen catching salmon from atop a platform—it can be even viewed online from a cam. Coastal areas host the highest population densities year round because there is a larger variety of food sources available, but Brooks Camp hosts the highest population bears.

An estimated individual bears have been identified at the falls in a single summer with as many as 74 at one time; [] 60 or more bears at the falls is a frequent sight, and it is not uncommon to see bears at the falls throughout a single day. An estimated grizzlies live on the island, which itself is only km 90 mi long. An estimated 3, Kodiak grizzly bears inhabit the island, 2, of these in the Kodiak National Wildlife Refuge. The grizzly bear is listed as threatened in the contiguous United States and endangered in parts of Canada.

Fish and Wildlife Service. Within the United States, the U. Fish and Wildlife Service concentrates its effort to restore grizzly bears in six recovery areas. The grizzly population in these areas is estimated at in the Northern Continental Divide, in Yellowstone, 40 in the Yaak portion of the Cabinet-Yaak, and 15 in the Cabinet portion in northwestern Montana , in Selkirk region of Idaho, 10—20 in the North Cascades, and none currently in Selway-Bitterroots, although there have been sightings.

In the recovery areas that adjoin Canada, bears also move back and forth across the international boundary. The U. On 9 January , the US Fish and Wildlife Service proposed to remove Yellowstone grizzlies from the list of threatened and protected species.

Fish and Wildlife Service “de-listed” the population, [] effectively removing Endangered Species Act protections for grizzlies in the Yellowstone National Park area.

Several environmental organizations, including the NRDC, brought a lawsuit against the federal government to relist the grizzly bear. On 22 September , U. District Judge Donald W. Molloy reinstated protection due to the decline of whitebark pine tree, whose nuts are an important source of food for the bears.

The population has risen from bears in to an estimated in , and was “delisted” in June They successfully sued the administration Crow Tribe et al v. Zinke and on July 30, , the Yellowstone grizzly was officially returned to federal protection. Farther north, in Alberta, Canada, intense DNA hair-snagging studies in showed the grizzly population to be increasing faster than what it was formerly believed to be, and Alberta Sustainable Resource Development calculated a population of bears.

A recovery plan released by the provincial government in March indicated the grizzly population is lower than previously believed. Environment Canada consider the grizzly bear to a “special concern” species, as it is particularly sensitive to human activities and natural threats.

In Alberta and British Columbia , the species is considered to be at risk. Conservation efforts have become an increasingly vital investment over recent decades, as population numbers have dramatically declined. Establishment of parks and protected areas are one of the main focuses currently being tackled to help reestablish the low grizzly bear population in British Columbia. One example of these efforts is the Khutzeymateen Grizzly Bear Sanctuary located along the north coast of British Columbia; at 44, hectares , acres in size, it is composed of key habitat for this threatened species.

Regulations such as limited public access, as well as a strict no hunting policy, have enabled this location to be a safe haven for local grizzlies in the area. The Refuge for Endangered Wildlife located on Grouse Mountain in Vancouver is an example of a different type of conservation effort for the diminishing grizzly bear population.

The refuge is a five-acre terrain which has functioned as a home for two orphaned grizzly bears since Another factor currently being taken into consideration when designing conservation plans for future generations are anthropogenic barriers in the form of urban development and roads. These elements are acting as obstacles, causing fragmentation of the remaining grizzly bear population habitat and prevention of gene flow between subpopulations for example, Banff National Park.

This, in turn, is creating a decline in genetic diversity, and therefore the overall fitness of the general population is lowered. In the United States, national efforts have been made since for the recovery plan of grizzly bears. The Interagency Grizzly Bear Recovery Committee is one of many organizations committed to the recovery of grizzly bears in the lower 48 states.

Fish and Wildlife initiated the process of an environmental impact statement that started in the fall of to begin the recovery process of grizzly bears to the North Cascades region.
