Assessing Wetland Restoration on the Delmarva Peninsula using Vegetation Characteristics
With wetland restoration, post-restoration monitoring is essential for determining developmental trajectories, particularly when comparing to natural reference systems. As part of the Mid-Atlantic Conservation Effects Assessment Project, 15 depressional wetlands on the Delmarva Peninsula of …

Predicting the effect of wetland restoration on phosphorus retention, Northwest Minnesota
… loading to surface water is to create or restore wetlands in agricultural areas that drain cropped fields. It is commonly believed that wetlands improve water quality, but research has shown that restoring wetlands can actually release phosphorus (P) into solution. Reducing conditions caused by …

Between Swamp and Sea: Agroforestry as Wetland Restoration in Southeast Virginia
… marsh migration without sacrificing forested wetland or productive value. Observational studies of marsh migration into coastal forests are well documented, though the mechanisms and determinants behind this conversion are complex and have only recently been given attention. I synthesize …

Comparison of wetland restoration techniques in and around Turnbull National Wildlife Refuge, Cheney, WA
<p>Throughout the West, wetlands have been drained or filled in for agricultural or urban uses. Staff at Turnbull National Wildlife Refuge (TNWR) in Cheney work with local landowners to restore wetlands through excavation or flooding techniques. Unfortunately, TNWR staff cannot evaluate the …

A Perceptual Study of Wetlands: Implications for Wetland Restoration in the Urban Area in Malaysia
The restoration of natural wetlands is a wonderful, noble and pragmatic idea, but such efforts often meet resistance from certain segments of society. One reason for this is that the public perceives the environment in different ways than do the experts, such as landscape architects and land …

Coastal Wetland Dynamics Under Sea-level Rise and Wetland Restoration in the Northern Gulf of Mexico using Bayesian Multilevel Models and a Web Tool
… how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland …

Ecohydrology of Natural and Restored Wetlands in a Glacial Plain
<p>More than half of wetland area in the U.S. have been converted to other land use types for agricultural use and development. Limited understanding of ecological services provided to society by wetlands is another reason for the massive wetland loss in the past. Section 404 of the Clean Water Act …

Assessing restoration potential in relict wetland soils: investigating the effect of wetland hydrology on soil microbial community composition and denitrification potential
… influence rates of biogeochemical cycling in wetland ecosystems; specifically, they are strong determinants of rates of denitrification typically observed. Human induced land use changes have significantly reduced the acreage of wetland habitats, with dam building in the eastern United States …

Denitrification and greenhouse gas emissions from cultivated and wetland alluvial soils
… practices (BMPs) to reduce NO3 loss and wetlands restoration to remove NO3 through denitrification are critically needed. The objectives of this research were to determine factors controlling denitrification potential of different landscape units in an agricultural watershed and quantify …

Novel water-use strategies of Colorado wetland plants: implications for wetland water loss
In the arid west, there is a tension between wetland restoration and water rights. Wetlands, relied upon by humans and wildlife alike, also contribute significantly to evapotranspiration (ET) due to higher water tables and dense vegetation. It is therefore critical to understand how much water …

Evaluating Surface Area-Basin Volume Relationships for Prairie Potholes
… prediction of floods and improved design for wetland restoration. Length, width, depth, surface area, and volumes were surveyed for eighty two potholes within the upper Turtle River watershed which lies sixty kilometers west of Grand Forks, ND. These data were used to determine the …

Floral and Faunal Colonization of Restored Wetlands in West-Central Minnesota and Northeastern South Dakota
… Plan (USFWS-CWS 1986) have together made wetland restoration a priority management activity for natural resource managers. A paucity of knowledge exists about the temporal capability of restored basins to attain attributes comparable to natural wetlands. The objective of this study was to …

Predicting Spatial Variability of Soil Organic Carbon in Delmarva Bays
Agricultural productivity, ecosystem health, and wetland restoration rely on soil organic carbon (SOC) as vital for microbial activity and plant health. This study assessed: (1) accuracy of topographic-based non-linear models for predicting SOC; and (2) the effect of analytic strategies and soil …

Spatial and Temporal Trends in Greenhouse Gas Fluxes from a Temperate Floodplain along a Stream-Riparian-Upland Gradient
Increased floodplain and wetland restoration activity has raised concerns about potential impacts on the release of greenhouse gases (GHGs) to the atmosphere due to restored connectivity between aquatic and terrestrial ecosystems. Research has shown GHG fluxes from hydrologically active landscapes …

An investigation of the biogeochemical exchange of the macro plant nutrients phosphorus and nitrogen on rewetted peat soil on the Somerset Levels and Moors.
… nitrate, and iron on a peat-based agricultural wetland; the factors affecting the temporal but also spatial distribution of phosphate, nitrate, and iron; and how restoration activities on a peat-based wetland impact these concentrations. Iron can bind to bioavailable phosphates which can also …

An Examination of the Legal, Social, and Environmental Issues That Surround the Restoration of Tidal Hydrology in Edisto Beach, South Carolina
… flooding have far-reaching impacts in coastal wetlands, including altered vegetation, sediment biogeochemistry, water quality, sediment inputs, fish and wildlife populations, recreational use, and potential future uses. There is an increasing interest to wetland hydrology restoration. Wetland …

Tradeoffs among ecosystem services in restored wetlands
Recently restoration ecology and land management have found new focus and direction by emphasizing the value of ecosystem services to society. Resource management decisions frequently involve choices that reflect tradeoffs among ecosystem services. Tradeoffs occur when one service changes at the …
