A report compiled by various government and research organizations including the University of Alberta and the BC Ministry of Forests, Lands and Natural Resources, Resource Roads and Grizzly Bears seeks to pull together the information contained in various scientific literature on the relationship between grizzly bears, human motorized access and efficacy of motorized access control as a tool to benefit bear conservation in western Canada. Resource roads are increasing in BC at a rate of 10,000 km of new roads per year, but no data are collected on the rate roads become unusable, either through natural processes or deactivation.
