Forest Biodiversity SOE Bulletin No.
Roads can change, or introduce human uses that change, forest biodiversity.
They are the forerunner of urbanization, agriculture, forestry, and mining and energy projects. Roads can affect forest biodiversity by, for example, increasing edge habitat, encouraging the spread of non-native species, and by facilitating recreational activities such as hunting. Accordingly, roads can benefit some species, and can be detrimental to others. The extent of road access in Canada's forests varies widely. This indicator uses road access as a surrogate for human influences on forest biodiversity.
