DESCRIPTION• It has brown and grizzled looking fur• A full grown bear can range between 5 and 8 feet tall• Grizzly bears are powerful predators. Much of their diet consists

of nuts, berries, fruit, leaves, and roots. Bears also eat other animals, and kill their own species.

• They can run 30 miles per hour• They are a keystone species

WHERE IS THE GRIZZLY BEAR FOUND?

• Grizzlies once lived in much of western North America and even roamed the Great Plains.

• Currently:• Montana • Washington• Wyoming• Idaho• Canada• Alaska

WHY IS IT ENDANGERED?• It is a threatened species.• Habitat destruction and competition with people for space eliminated

them from much of the United States, pushing their population into Canada and Alaska.

• Livestock depredation control• Habitat deterioration• Commercial trapping• Unregulated hunting• The perception that grizzlies threaten human life

HOW MANY REMAIN? • Today only about 1,000 Grizzlies remain in the continental U.S., where they

are protected by law.• 350 (northwestern Montana Rockies), 350-400 (in or around Yellowstone

National Park), 10 (Selkirk Mountains), 15 or so (Cabinet-Yaak ecosystem), and perhaps 10 or more (North Cascades)

• In Canada and Alaska many Grizzly Bears still roam and are hunted as big game trophies.• Estimated populations of the Grizzly were

• 1,200 in Alberta• 6,500 in British Columbia• 4,000 to 5,000 in the Northwest Territories• 31,000 in Alaska

• It is estimated that hunting, poaching, and other human related activities are responsible for the deaths of 6,335 grizzlies every year.

WHY IS THE GRIZZLY IMPORTANT?

• Grizzly Bears are sometimes called “ecosystem engineers”• They help build and change the ecosystem in which they are a part• They contribute to nutrient cycling and seed dispersal

• Bringing nitrogen back into the environment through leaving salmon pieces through the forests.

• They are a predator to moose, elk, salmon, and other bears

WHAT IS BEING DONE TO REVITALIZE THE SPECIES?

• The National Wildlife Federation • Expand habitat in Yellowstone National Park• Reestablish populations of Grizzly Bears in areas that are stable enough to

support the bears• Wilderness areas of central Idaho

• Working to stop dangerous projects that are threatening the natural habitat of the Grizzly Bears further

WHAT CAN BE DONE TO FURTHER HELP THE SPECIES?

• People who live in areas with Grizzly Bears should restrict access to garbage, dog food, bird food, dead livestock, etc., so that the bear does not become a threat and destroyed.

HOW SUCCESSFUL ARE OUR EFFORTS?

• They were was delisted in 2007, relisted in 2010 due concerns about habitat loss and global warming, and declared recovered by the U.S. Fish and Wildlife Service in 2011.

• However issues include that the bears move into tourist areas of national parks. Also, people illegally shoot the bears when they come near their property or livestock.
