The Sierra Club has suggested that the U.S. government more than triple the number of acres designated as recovery areas for grizzly bear populations in Idaho, Montana, and Wyoming, up from 5.9 million acres to 19.9 million. A Sierra Club study indicates that grizzly bears need areas of more than 1,000 square miles in order to survive. In other grizzly news, the U.S. Fish and Wildlife Service next year may start importing bears from British Columbia to restore populations in the vast Selway-Bitterroot Wilderness Area in Idaho and Montana. Some Canadian enviros oppose the plan, arguing that Canadian bear populations are under too much pressure already.
