The effects of roads on wetland diversity take about 3-4 decades to be fully realized (Findlay and Bourdages 2000). Road-effect zones occur due to disturbances from high-volume traffic, which can reduce the habitat quality near roads . Breeding densities and distribution of many species are reduced adjacent to busy roads.
