Grizzly bears inhabit a vast territory that spans across western Canada and the northwestern United States. Their habitat includes large areas of wilderness, such as forests, tundras, and mountainous regions.
Grizzly bears have a complex relationship with their environment, relying on various features like rivers, lakes, and wetlands to sustain themselves. These water sources provide them with food, shelter, and a means of transportation.
In the summer, grizzly bears can be found roaming through alpine meadows and tundras, where they feed on grasses, berries, and other vegetation. This seasonal migration is crucial for their survival, as it allows them to adapt to changing food availability.
Grizzly bears also require large areas of undisturbed habitat to den and raise their young.
Grizzly Bear Habitat and Behavior
Grizzly bears prefer open or semi-forested areas on all parts of their range and are most common in alpine and subalpine terrain or on the tundra.
They can also be found in boreal forests, although sightings in these areas are not unusual. Their home range can encompass up to 600 square miles, so they need a lot of space to roam and forage.
Grizzlies are opportunistic predators and will kill moose, muskoxen, and sheep if the occasion arises. They also eat a variety of plants, including horsetails, berries, legume roots, and grasses, which make up about 90 percent of their diet in some areas.

Natural History
Grizzly bears are found in a variety of habitats, including mountains, forests, and tundras. They are well adapted to living in areas with abundant food sources and suitable denning sites.
In the western parts of North America, grizzly bears inhabit areas with abundant salmon runs, a crucial food source for them. Their diet consists mainly of plants, nuts, berries, and fish.
Grizzly bears are excellent swimmers and have been known to swim for hours or even days at a time. They are also skilled climbers and have been spotted climbing trees in search of food.
Grizzly bears typically hibernate for 5-7 months during the winter months, during which time their heart rate slows down dramatically. They will often den in a sheltered location, such as a cave or a hollowed-out tree.
In areas with high human activity, grizzly bears can become habituated to human food and trash, leading to conflicts between humans and bears.
Habitat
Grizzlies prefer open or semi-forested areas on all parts of their range and are most common in alpine and subalpine terrain or on the tundra.
Historically, grizzly bears roamed from the western United States to Mexico, but habitat loss and overhunting have significantly reduced their range.
Grizzlies are opportunistic predators and will kill moose, muskoxen, and sheep if the occasion arises.
Their home range can encompass up to 600 square miles, so their ideal habitat is one that is isolated from development and has plenty of food and places to dig their dens.
Grizzlies in the NWT eat all kinds of food, with plants making up about 90 percent of their diet in the Mackenzie Mountains.
Despite past population declines, conservation efforts have led to a remarkable resurgence, with approximately 728 grizzly bears recorded as of 2019.
Grizzly bears in the boreal forest are not unusual sightings, and they can also be found in parts of Wyoming, Montana, Idaho, and Washington State.
Conservation and Threats
Grizzly bears once thrived in their habitats, but their numbers dwindled dramatically due to westward expansion and aggressive hunting in the early 20th century.
At its peak, the grizzly population numbered more than 50,000, but by the 1920s and 1930s, these bears had been reduced to less than 2 percent of their historical range.
In the 1960s, it was estimated that there were only 600 to 800 remaining in the wild, a stark contrast to their former abundance.
The grizzly bear's population continued to decline until 1975, when they were listed as threatened under the U.S. Endangered Species Act.

Grizzly Bears: Movement and Population
Grizzly bears have historically roamed from the western United States to Mexico.
Their range has significantly reduced due to habitat loss and overhunting. Today, they're primarily found south of Yellowstone National Park.
Concentrated populations exist in Washington, California, Idaho, northern Canada, and Alaska.
Conservation efforts have led to a remarkable resurgence, with approximately 728 grizzly bears recorded as of 2019.
Yellowstone Bear World provides a safe and thriving environment for grizzly bears within the Greater Yellowstone Ecosystem.
Insights and Information
Grizzly bears are omnivores, which means their diet primarily consists of vegetation, supplemented by insects and small animals. They seek out areas with diverse plant life to satisfy this dietary need.
Grizzly bears need expansive territory to roam and forage, which is why Yellowstone National Park is an ideal home for them. This park provides them with the space they need to thrive.
As omnivores, grizzly bears also require accessible prey to supplement their plant-based diet. They rely on rich insect populations and small animals to meet their nutritional needs.
Grizzly bears need safe denning sites for hibernation, which is a critical component of their survival. They seek out secluded areas to den and hibernate during the winter months.
