Naturalization aims to minimise negative impacts of the built environment on natural aquatic landscapes i.e. protect water quality and habitat by the establishment of planted riparian margins to waterways and wetlands. Planted riparian margins prevent polluted runoff entering the waterway. This not only improves water quality and habitat, but also improves social amenity, cultural and ecological values in urban areas.
