A BLESSING AND A CURSE? STORMWATER PONDS PROVIDE MULTIPLE POSITIVE AND NEGATIVE EFFECTS IN URBAN WATERSHEDS

Stormwater wet ponds (SWPs) are a common strategy implemented worldwide intended to minimize the hydrological and ecological impacts of urbanization that drive the urban stream syndrome. Although SWPs are typically designed primarily for flood control, these engineered aquatic ecosystems represent key junctions between the built and natural environments. There are at least 76,000 SWPs in Florida alone, covering nearly as much space as urban industrial or recreational areas. Here we present ongoing research focused on the duality of SWPs: the positive and negative effects these real aquatic ecosystems have in urban watersheds. Specifically, SWPs represent key habitat for aquatic and semi-aquatic plants and animals but can also harbor invasive species. Denitrification within SWPs can rapidly respond to nutrient pollution events but ponds are also often sources of nitrogen to downstream ecosystems via nitrogen fixation in sediments. SWPs can be aesthetic amenities for the surrounding community, but aesthetic expectations can negate ecological potential via altered pond management. Ultimately, SWPs are designed to protect downstream ecosystems, but a better understanding of the ecological processes within SWPs, and how management affects these processes, is needed to ensure they are protecting downstream water bodies.
