Nutrient Dynamics in a Restored Wetland

This research expands the understanding of the effects of hydrological restoration on nutrient reduction in a wetland associated with the Mississippi River Basin. The objective of this project was to observe the degree to which wetland restoration can sequester excess soil nutrients to improve water quality. Soil characteristics at sites in riparian wetlands following the initiation of Redman Point-Loosahatchie Bar Environmental Restoration Project were compared. Field sites were established in the Loosahatchie Chute, based on relative distance south of the notched dikes. Additionally, a natural riparian site was monitored. Soil samples were evaluated for spatial and seasonal differences in moisture content, bulk density, total carbon (C), nitrogen (N), and phosphorus (P). Measurements of total C, total N, and P were reduced at all sites compared to the reference site. Although hydrology has been restored to the wetlands, functionality may take a considerable amount of time to be detectable. © 2014 Taylor & Francis Group, LLC
