High rates of wetland loss have stimulated restoration and creation projects aimed at recovering ecosystem structure and function, as well as the ecosystem services upon which humans depend. While wetland creation can achieve similar vegetation structure to natural wetlands, it often fails to fully recover similar ecosystem functions, like primary productivity, carbon sequestration, and nutrient removal. The objective of this project is to compare and contrast ecosystem structure and function in a natural tidal salt marsh and two 30-year old, created marshes along the Fowl River in Mobile County, AL.
Our team is characterizing hydro-edaphic conditions, bioturbation activity, plant community composition, primary productivity, organic matter decomposition, nitrogen removal capacity, and carbon stocks and fluxes in all three sites. The proposed work will be the first to thoroughly examine the constructed marshes of the Fowl River, and will serve as the foundation for a series of studies on plant productivity, decomposition, and carbon and nitrogen cycling at these sites. This project will (1) permit evaluation of wetland creation success, (2) identify shortcomings and trajectories of wetland recovery, and (3) inform management strategies to recover ecosystem services. |
The TeamOur team has experience in community ecology, ecosystem ecology, and biogeochemistry of tidal marshes. In addition to Drs. Cherry and Mortazavi, our group includes post-docs (Drs. Corianne Tatariw and Lorae' Simpson), graduate students (Abbey Griffin, Taylor Ledford, Erin Smyth, and Sommer Starr), and a number of undergraduate students.

Natural and constructed marshes are both dominated by healthy stands of black needlerush, yet rooting depth and soil organic matter is greater in the natural marsh (top panel) compared to the constructed marshes (bottom panel). (Photo credit: J. Cherry)
