The grizzly bears of Yellowstone National Park were once habituated to human presence, surviving on trash intentionally left by the park's attendants. Since the reversal of the park's policy in 1972, the grizzly bears have learned to hunt, ending their dependence on humans. The grizzlies' return to the wild has positively impacted their survival, but has been detrimental to cattle ranchers who have settled in the surrounding areas of Yellowstone. In this video segment from Nature, meet a cattle rancher who was unable to prevent the bears from attacking his livestock.

Print Background EssayGrizzly bears were once scarce in Yellowstone National Park and on their way to extinction. After becoming designated as an Endangered Species over three decades ago, governmental protections have allowed these natural predators to make a comeback. But the grizzly’s success has come at a destructive and often dangerous price for people living nearby. Maintaining a delicate balance between humans and the resurgent grizzlies continues to challenge conservationists today.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
