Grizzly Bears: Are large and range in color from very light tan (almost white) to dark brown. They have a dished face, short, rounded ears and a large shoulder hump The hump is where a mass of muscles attach to the bear’s backbone and give the bear additional strength for digging. They have very long claws on their front feet that also give them extra ability to dig after food and to dig their dens.
Vital Ground is working to preserve grizzly bear habitat in the Cabinet-Yaak Mountains in northern Idaho and northwestern Montana. Grizzly habitat in this ecosystem is threatened by increasing development, highway traffic and a mjor railway that fragments the landscape (Photo by Linda Lantzy): http://www.vitalground.org/conservation-work/places-projects/cabinet-yaak/
Grizzly Bears- Icons of unspoiled wilderness, grizzly bears require large areas of intact habitat to survive. Their slow reproduction rate means that their populations are especially sensitive to human-caused mortality, such as trophy hunting and conflicts caused by habituation or lack of food. They lunch on slamon also.Mama is going to give cubs a lesson. | Pacific Wild
A Grizzly Bear catches a salmon in the Great Bear Rainforest. The Harper government is planning to gut the powers in federal legislation intended to protect fish habitat, making it easier for projects like Calgary-based Enbridge Inc.'s Northern Gateway pipeline to B.C. to clear federal hurdles, according to a retired fisheries biologist who obtained the information from a government source.
Despite the richness of high-quality habitats in Yosemite, approximately 40 species have a special status under California endangered species legislation. Three species--grizzly bear, California red-legged frog, and foothill yellow-legged frog--are believed to be extirpated in the park within recent history. Serious threats to Yosemite's wildlife and the ecosystems they occupy include loss of a natural fire regime, exotic species, air pollution, habitat fragmentation, and climate change.
Once ranging from Mexico to Alaska, their population has been reduced nearly to the point of extinction from habitat destruction and over-harvesting. The grizzly population has remained stable for the past 20 years, but there are probably fewer than 1,000 bears left in the western United States. They are currently classified as a “threatened” species. Grizzly bears are now facing new threats from climate change.
