SuDS and amphibians - are constructed wetlands really benefitting nature and people?

Abstract

While urbanisation is a major threat to global biodiversity, it also brings opportunities for some species. Sustainable Drainage Systems (SuDS) have been installed in all Scottish cities to reduce flood and pollution risk and they can also offer new habitats for wildlife. We studied SuDS in Inverness and the Scottish Central Belt to assess their value as amphibian breeding sites, habitats, and as places where urban people can experience nature. The nine-year study revealed that many SuDS were of similar ecological quality to wider countryside ponds but that the quality of ponds is not equitably distributed between neighbourhoods inhabited by different socio-economic classes. However, the findings suggest ways to improve the design and management of SuDS for people and nature, making access to high quality ponds available to all social groups.
