[1] Wetland restoration is a commonly used approach to reduce nutrient loading to freshwater and coastal ecosystems, with many wetland restoration efforts occurring in former agricultural fields. Restored wetlands are expected to be effective at retaining or removing both nitrogen and phosphorus (P), yet restoring wetland hydrology to former agricultural fields can lead to the release of legacy...

Communities along the USA coast are highly vulnerable to coastal storms. Trends in population growth, climatic events and land use are likely to exacerbate future damages. Coastal management entities are faced with decisions about how to manage resources in a manner that improves environmental quality and provides the maximum benefit for coastal populations. This is particularly true along the ...

Habitat loss is one of the key factors underlying the decline of many waterbird species, including Siberian Crane (Grus leucogeranus), a threatened species worldwide. Wetlands are the primary stopover for many waterbirds and restoration of these wetlands involves both hydrological restoration and water resource management. To protect the stopover sites of Siberian Cranes, we collected Siberian ...

Wetland restoration is globally important for offsetting effects of wetland loss and degradation but is not consistently successful. Vegetation studies provide insight into the effectiveness of restoring wetland ecosystem functions. We compared plant community composition in 47 non-tidal wetlands under different management (natural, restored, and former wetlands that had been converted to cropl...

Ecological data from land surveys from 1811 for the 100,000-acre Connecticut Tract in western New York were transcribed and then analyzed using ArcGIS and IDRISI GIS software. The surveys contained both witness tree data and line descriptions, which were analyzed for species composition and community type. Results illustrate that many changes have occurred in species composition. Possible cause...

PURPOSE: One of many potential uses of the hydrogeomorphic (HGM) approach for assessing wetland functions is the monitoring of newly restored wetland sites to determine how quickly wetland functions develop and whether function-based mitigation objectives are being met. This technical note presents a case study of the application of the Western Kentucky Low-Gradient Riverine Guidebook to monito...

We used a before-after-control-impact study across three years to assess the effects of active riparian restoration on bird densities and community composition. Birds density post-restoration on actively-restored plots averaged 25 birds ha -1 versus 15 birds ha -1 on controls. We conclude that active restoration should be pursued to benefit bird populations.

wetland functions is the monitoring of newly restored wetland sites to determine how quickly wetland functions develop and whether function-based mitigation objectives are being met. This technical note presents a case study of the application of the Western Kentucky Low-Gradient Riverine Guidebook to monitoring the development of wetland functions on a number of bottomland hardwood forest site...
