URBAN BASEFLOW: A BOON AND A CURSE FOR ACCIDENTAL WETLAND ECOSYSTEMS?
Unintentionally created wetlands in urban areas demonstrate significant capacity to provide ecosystem services, particularly when connected (or reconnected) with water sources. A common water source is dry weather flows, i.e., urban baseflow, where wastewater inadvertently creates surface water inputs to abandoned areas of the urban landscape, in turn creating wetland ecosystems that can be sustained during dry periods. In this sense, urban baseflow is an asset to accidental wetlands, in that it creates and sustains them hydrologically, and delivers substrates (e.g., nitrate and organic matter) that support important ecosystem functions (e.g., nitrate removal). However, my research also suggests that the composition and availability of urban baseflow can negatively affect the persistence and function of accidental wetland ecosystems. For example, excess water from flood-irrigated golf courses can create accidental wetlands, but also overload those wetlands with nutrient and salt inputs in excess of their processing ability. Additionally, accidental wetlands may not have hydrologic regimes optimal for pollutant processing or plant growth, depending on wastewater input frequency. I will discuss data from the northeastern and southwestern US demonstrating patterns and tradeoffs in the relationship between urban baseflow and accidental wetland ecosystem function.
