Grizzly Bears in Danger
Without government protection, an icon of the American West could return to the brink of extinction.
In the early 1800s, as many as 100,000 grizzly bears roamed the Western United States. But after hundreds of years of hunting and habitat destruction, the number of grizzlies in the American West has plummeted to about 1,500.
Why do grizzly bears matter? And why should Americans care about them?
Here's what NRDC grizzly expert Louisa Willcox has to say about that:
Grizzly bears are icons of the wild high country of the American West. When Lewis and Clark explored the West, grizzlies roamed from the Great Plains to California, and from Alaska to Mexico. Today, however, the grizzly population in the lower 48 states is about 1 percent of estimated pre-colonial levels, and the few bears that remain are concentrated in shrinking pockets of the northern Rockies and North Cascades.
Any American who cares about this nation's history has a stake in conserving grizzly bears and their wildland habitat. Healthy bear populations mean that the land and other wildlife species are healthy. Our children and grandchildren deserve the chance to experience for themselves these wild landscapes and their animals.
According to wildlife biologists, the grizzly population must at least double its current size in order to ensure a full recovery. At the same time, the bear's habitat must be restored and protected.
The land that is home to the remaining grizzlies faces threats from drilling, logging and other human development and sprawl. Their western habitats are also threatened by global warming. In the land in and around Yellowstone National Park, grizzlies rely on fatty whitebark pine seeds for nourishment before their yearly hibernation. Living at high elevations in these remote forests also keeps grizzlies out of harm's way and reduces conflict with humans. But rising temperatures have enabled mountain pine beetles to kill these trees, threatening the future of Yellowstone's grizzlies.
