Riparian, or “riverside,” forested buffer zones are tracts of forest vegetation that extend inland from river banks. They play an integral role in maintaining ecosystem structure and function. They buffer the effects of contaminants, nutrients and sediments which drain into a river, and moderate the velocity and volume of run-off. They provide shade and energy (from terrestrial organic matter) and are crucial factors in controlling bank stability and erosion. Riparian forests provide habitat, foraging, refuge and breeding grounds for numerous semi-aquatic and terrestrial species and in doing so act as important biological corridors in their own right.
