This project (funded by the US Army Corps of Engineers Engineering Research & Development Center) will provide insight into interactions among wetland plants and dissolved nutrients in riverine freshwater wetlands. We are using flow-through wetland mesocosms to study interactions between invasive and non-invasive plant species in wetlands of the lower Mississippi River Valley, under "normal" and elevated levels of dissolved nitrogen.

Our aim in this work is to better understand the effects of particular plant species on nutrient dynamics in wetlands, especially in the face of invasion by aggressively growing plant species. A secondary objective is to provide data that will parametrize models being developed by ERDC scientists to better understand and manage plant productivity in riverine wetlands.
