After eight years of often contentious negotiation among environmentalists, Native Americans, and representatives of the mining and logging industries, British Columbia has approved a plan to preserve 5 million more acres of land. The area in northern B.C. connects with the 11 million-acre Muskwa-Kechika preserve and is an important part of a huge wildlife corridor, stretching from Yellowstone in the U.S. to the Yukon in Canada, that enviros are trying to protect. Mining and logging will be regulated in parts of the new preserve, while sensitive habitat will be protected from such activities. The preserve has the greatest number of large mammals in North America, including grizzlies, wolves, moose, and bison.
