Native Canadian groups, environmentalists, and timber company MacMillan Bloedel signed a deal yesterday to end Canada’s most bitter forest fight. The agreement supports the use of selective, sustainable logging in Clayoquot Sound on Vancouver Island only in second-growth and fragmented old-growth stands, not in large pristine watersheds. Greenpeace Canada and the U.S.-based Natural Resources Defense Council will help market the sustainably harvested timber products. The plan, though not legally binding, is being touted as an international model.
