Evaluation of a Water Budget Model for Created Wetland Design and Comparative Natural Wetland Hydroperiods
Wetland impacts in the Mid-Atlantic USA are frequently mitigated via wetland creation in former uplands. Regulatory approval requires a site-specific water budget that predicts the annual water level regime (hydroperiod). However, many studies of created wetlands indicate that post-construction …

Faunal Diversity and Richness of Natural, Restored, Dam-Created, and Borrow-Pit Wetlands in the Prairie Pothole Region of Eastern South Dakota
An increasingly large percentage of wetland loss has occurred due to highway development within the last twenty years. In an attempt to compensate for these losses, the Federal Highway Administration has adopted new wetland mitigation policies. To facilitate the implementation of these policies, …

Salt marsh creation and coastal residential developments: principles and guidelines for landscape architecture practice
Salt marsh creation provides functions and values that are essential to maintain the welfare of people and the integrity of coastal area ecosystems. The literature review provides greater understanding of salt marsh functions and values technical information regarding wetland creation in coastal …

Influences of Soil Amendments and Microtopography on Vegetation at a Created Tidal Freshwater Swamp in Southeastern Virginia
… the traditional vegetation criteria for federal wetland jurisdictional determination, which only considers dominant species. When the same criteria were used for all of the species, the control, 1x, and 2x treatments met jurisdictional criteria. Considering these findings, vegetative criteria …

An Assessment of Sustainable Water Management at University Campuses
… revealed that institutions featuring stream and wetland restoration projects had greater odds of being described as having a developed watershed plan and taking into consideration multidisciplinary approaches to water management.</p><p>Case studies showed that wetland creation and restoration …

Macroinvertebrate communities inhabiting surface mine wetlands of southwestern Virginia
Wetland acreage in Southwest Virginia has increased because of formation of wetlands on relic surface mine benches. Prior to the Surface Mining Control and Reclamation Act of 1977 (PL 95-87) once mining operations were completed the sites were abandoned. These areas presented novel landscapes in …

Four-Toed Salamander (hemidactylium Scutatum) Nest Site Characteristics In Natural And Constructed Wetlands In Eastern Kentucky
<p>Forested freshwater wetlands have undergone loss and alteration more than other types of wetlands. Wetland creation has slowed wetland losses, but many created wetlands do not functionally replace natural wetlands. Plant and animal communities and wetland drying cycles often differ between …

Characterization of urban wetland vegetation and management practices
<p>Urban wetlands are important ecosystems that moderate flooding risks and improve water quality. Vegetation is a key component of urban wetlands; plants promote sedimentation, play critical roles in biogeochemical cycling, and provide food and habitats for other organisms. My research focuses on …

Initial Wetland Hydrology and Vegetation Composition in Predicted Wetlands Adjacent to Lake Naconiche, Nacogdoches County, Texas
… adjacent to the lake would be converted into wetlands. The purpose of the study was to evaluate the creation of wetlands around the lake and establish a benchmark of vegetation composition and condition for future comparison. Eight locations, placed where the majority of wetlands were expected …

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 …
