Accounting for Wetlands in Biocapacity: Data Integration, Sensitivity Analysis, and Implications
Wetlands play a critical role in climate regulation and ecosystem services provision. However, their transitional nature and variable hydrology complicate precise definition and consistent assessment across the globe, leading to data gaps and limited representation in environmental accounting …

Evaluation of Natural Remediation Following the Occurrence of a Construction-Related Sediment Plume at Camp Shelby Training Site, Mississippi
… sediment infill of a bottom land hardwood wetland at Camp Shelby Training Site (CSTS) in Perry and Forrest Counties, Mississippi. Lack of sediment control structures (sediment fences and matting), combined with high rainfall, led to erosion within and around the Multi Purpose Range …

Impacts of Wetland Characteristics on Duck Use in the Prairie Pothole Region (PPR) 1987-2013
… designed to assess the influence of the Small Wetlands Acquisition Program on contributions to continental waterfowl populations (Cowardin et al. 1995). Each year cooperators visit sample wetlands during two survey periods, collecting data on observed waterfowl and pond conditions. Along with …

Long-Term (24-Year) Effects of Harvest Disturbances on Ecosystem Productivity and Carbon Sequestration in Tupelo-Cypress Swamps in the Mobile-Tensaw River Delta
… twenty-four years after harvest on two major wetland functions: stand productivity and C storage. This study evaluated the effects of three harvest types that were originally applied in 1986 to a tupelo (Nyssa aquatic)-cypress (Taxodium distichum) forested wetland in the Mobile-Tensaw River …

Improving Wetland Mitigation in the Coastal Plain of South Carolina With the Watershed Planning and Mitigation Banking Aspects of the New Mitigation Rule
… aspects of the 'New Mitigation Rule' into the wetland mitigation framework of South Carolina. This project performed a watershed-scale wetland condition assessment, assessed wetland conditions in two Coastal Plain mitigation banks, and determined the spatial patterns of the use of the Coastal …

Decomposition Dynamics in Restored and Naturally Recovering Atlantic White Cedar (<i>Chamaecyparis thyoides</i>) Wetlands
… management practices for Atlantic white cedar wetlands have recently focused on soil organic matter sequestration and aggradation as critical ecosystem functions in the maintenance of this imperiled community type. This work addresses how developmental stage, litter quality and environmental …

Evaluation of the Basis and Effectiveness of Habitat Assessments in Wetland Functional Assessment Methods
I studied the basis and effectiveness of wetland assessment methods in providing habitat assessments. While it is well understood that wetlands and riparian areas provide important ecological functions and habitat for a wide variety of wildlife species, much is still to be learned about providing …

Wetland enhancement on an urban river : Issues of social and ecomic regeneration.
With a progressive and steady decline in wetland features, particularly in lowland Britain, industry, development, agriculture, drinking water abstraction and recreation have all been recognised to have played their part in degrading riverine features, surface wetlands and underground aquifers. …

Assessment of Wetland Mitigation in South Dakota
Wetland mitigation is the practice of avoiding, minimizing or compensating for wetland functions and values lost through human impacts (e.g., filling). Regulated by the Army Corps of Engineers (Corps) and the Environmental Protection Agency through Section 404 of the Clean Water Act, wetland …

Litter Decomposition in Created and Adjacent Forested Wetlands of the Coastal Plain of Virginia
… function of constructed and natural forested wetlands. This study compared rates of litter mass loss, changes in litter morphology, and associated macroinvertebrate populations in constructed and natural non-tidal wetlands. Two sets of wetlands (constructed vs. natural) were studied in eastern …

Environmental and Digital Data Analysis of the National Wetlands Inventory (NWI) Landscape Position Classification System
The National Wetlands Inventory (NWI) is the definitive source for wetland resources in the United States. The NWI production unit in Hadley, MA has begun to upgrade their digital map database, integrating descriptors for assessment of wetland functions. Updating is conducted manually and some …

Forage Potential of Seasonal Wetlands
Investigations on aspects of seasonal wetland forage potential were conducted in eastern South Dakota. The quantity and quality of the standing crop of vegetation in 6 seasonal wetland communities were assessed at the end of the growing season in 1983 and in 2 seasonal-wetland-dominated basins and …

Climatic Controls on the Porewater Chemistry of Mid-continental Wetlands
<p>Wetlands develop where climate and physiography conspire to maintain saturated soils at the land surface, support diverse plant and animal communities, and serve as globally important sinks for atmospheric carbon. The chemistry of wetland porewaters impacts near-surface biological communities …
