This tabular dataset is the result of an analysis completed for the Roads & Roadless Areas in B.C. indicator published on Environmental Reporting BC. Roaded and roadless areas were determined using the B.C. Digital Road Atlas, the best available single source of road data for British Columbia. The analysis was done on Digital Road Atlas data available as of May 1st, 2018. All paved roads and unpaved roads and trails that allow motorized vehicle use—as detailed in the Digital Road Atlas Data Dictionary—were included in the analysis. Some road features available in the Digital Road Atlas were excluded, including non-roads (ferry routes, proposed roads, pedestrian only roads, non-motorized trails and water access routes) and non-active roads (decommissioned and overgrown roads). Roaded areas were defined as areas within 500 metres of a road. Roadless areas were defined as areas greater than 500 metres from a road. Areas are reported in hectares to three significant figures for two distance classes: 0 to 500m from a road (roaded) and greater than 500m from a road (not roaded) for British Columbia and for each ecoregion.
