Road density is a serious issue in BC. Reports such as https://www.for.gov.bc.ca/hfd/pubs/Docs/En/En120.pdf indicate that animals such as Grizzlies and other species will retreat from an area once road density reaches a certain level. Some suggest once road density reaches 0.6km of road / km^2 Grizzly bears will largely retreat from the area.
Additionally, humans and predators use roads to improve hunting efficiency, putting increased pressure on prey species. Road deactivation will help restore moose and bear populations for improved hunting opportunities in the future. We should all be advocating for deactivation and habitat restoration.
