  1. The grizzly bear by: Colleen Regan Period 4A http://animals.nationalgeographic.com/animals/mammals/grizzly-bear/

  2. 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 http://www.concierge.com/images/destinations/destinationguide/usa%2Bcanada/usa/alaska/seeanddo/bearwatching/grizzlybearsalmon_001p.jpg http://imgc.artprintimages.com/images/art-print/james-hager-grizzly-bear-ursus-arctos-horribilis-standing-in-the-snow-near-bozeman-montana-usa_i-G-62-6242-LSJ3100Z.jpg http://www.successfulworkplace.org/2013/11/20/youre-going-change-culture-quickly

  3. 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 http://www.nrmsc.usgs.gov/research/CYEbeardna_detail

  4. 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

  5. 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.

  6. Why is the Grizzlyimportant? • 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

  7. 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

  8. 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. http://ken-cdn.com/sites/default/files/imagecache/superphoto/12024037.jpg

  9. 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. http://www.esasuccess.org/report_2012.html
