Interpretive Summary: Wetlands provide valuable ecosystem services, but continue to be threatened worldwide. This article introduces a collection of articles that explore current research and thinking on wetland ecosystem resilience. The Collection contains articles on wetland resiliency to climate change, agricultural land use-driven change, and recreational land use along with evaluation of wetland resiliency through high-resolution monitoring and modeling tools. Wetlands studied in this collection span tidal marshes and coastal plain non-riverine wetlands in North Carolina, prairie potholes in Iowa, Appalachian floodplain wetlands, and floating treatment wetlands in the Midwestern U.S. The studies found accumulation of 0.7 to 4.0 mm/yr of sediments in a tidal marsh, a wide range of potential wetland hydroperiod responses to climate change, substantial decreases in inundation period, crop yield, and surface-water nitrate (but increases in phosphorus) in artificially drained potholes, and nitrate removal in carbon-amended floating treatment wetlands. Further work is needed to better understand how to design and enhance wetland systems in agricultural regions, better preserve wetland ecosystem services in areas affected by land use and climate change, and provide technical standards for the wide range of designs currently used for wetland treatment systems.

Technical Abstract: The objective of this article is to introduce a collection of articles that explore current research and thinking on wetland ecosystem resilience. The Collection contains articles on wetland resiliency to climate change, agricultural land use-driven change, and recreational land use along with evaluation of wetland resiliency through high-resolution monitoring and modeling tools. Wetland settings span tidal marshes and coastal plain non-riverine wetlands in North Carolina, prairie potholes in Iowa, Appalachian floodplain wetlands, and floating treatment wetlands in the Midwestern U.S. The studies found 0.7 to 4.0 mm/yr vertical accretion rates in a tidal marsh, a wide range of potential wetland hydroperiod responses to climate change, substantial decreases in inundation period, crop yield, and surface-water nitrate (but increases in phosphorus) in artificially drained potholes, and nitrate removal in carbon-amended floating treatment wetlands. Further work is needed to better understand how to design and enhance wetland systems in agricultural regions, better preserve wetland ecosystem services in areas affected by land use and climate change, and provide technical standards for the wide range of designs currently used for wetland treatment systems.
