Global wetland loss has reduced biodiversity and ecosystem services. These declines have inspired many landholders to restore wetlands, but the success of these efforts remains unclear, in part, because quantifying services requires diverse methods. Here, we blend participatory mapping surveys, field measurements high-resolution models track from restored wetlands on private land. We ask: 1) Wh...

Setting priorities for protection and restoration efforts is necessary whenever resources are not sufficient to target all sites simultaneously. When this occurs priorities should be set to maximize the ecological benefit gained from available resources. Prioritizing protection and restoration efforts in this fashion is hampered, however, by a lack of information that can be used by resource ma...
The Field Assessed Benefit and Design Strategy (FABADS) was introduced by the U.S. Army Cops of Engineers as part of the Upper Susquehanna River WatershedCooperstown Area Ecosystem Restoration Feasibility Study and Integrated Environmental Assessment. Authorized by the U.S. Congress, the pilot program is “to conduct a study and develop a strategy for using wetland restoration, soil and water co...
Over the past 50 years, large areas of agricultural land have been drained and put into intensive agricultural production. Increasing attention is now being paid to the issue of restoring wetland areas and promoting environmental benefits. Collective action is important for wetland restoration, both because of the physical interactions among landholders and because of the cost saving and enhanc...
Lake Winnipeg is Canada’s 6th largest freshwater lake and is subject to an increasing rate of eutrophication as a result of nonpoint source pollution from numerous sources including farms and municipal wastewaters. We examine scenarios designed to compare the relative effects of wetland restoration and position on modelled nutrient loadings to Lake Winnipeg from a pilot watershed in the Lake’s ...

For more than 100 years, the wetland sediments at the Indiana Dunes National Lakeshore (IDNL) and adjacent Indiana Dunes State Park have received atmospheric input of trace metals from industrial sources located upwind and to the west. The objective of this study was to document the extent and magnitude of this trace metal pollution both aerially and with depth within the IDNL, and to identify ...
The paper deals with a 100 ha wetland in an estuary of the capital area of Finland. The area has gone through major changes in the last decades due to land based and river borne nutrient loads, resulting in unfavourable living conditions for aquatic birds. In order to restore the overgrown areas, opening inner ponds and brook channels by dredging is planned, in combination with dam construction...
The aim of this study was to identify and make an initial accounting of the ecosystem services of the hydroelectric power generation plant, UHE Carlos Botelho (Itirapina Municipality, São Paulo State, Brazil), and its most extensive wetlands total of 2,640 ha and also identify the drivers of change of these services. Twenty (20) ecosystem services were identified and the estimated quantitative ...
