“…; Leeper and Taylor ; Zedler ). Observations that nonfloodplain wetlands such as prairie potholes often lack endemic biota (i.e., biota restricted to a small geographic area) suggest that these habitats are not isolated over sufficiently long time frames to allow local speciation, and thus have been or currently are biologically connected to other aquatic habitats (van der Valk and Pederson ).…”

Freshwater ecosystems are linked at various spatial and temporal scales by movements of biota adapted to life in water. We review the literature on movements of aquatic organisms that connect different types of freshwater habitats, focusing on linkages from streams and wetlands to downstream waters. Here, streams, wetlands, rivers, lakes, ponds, and other freshwater habitats are viewed as dynamic freshwater ecosystem mosaics (FEMs) that collectively provide the resources needed to sustain aquatic life. Based on existing evidence, it is clear that biotic linkages throughout FEMs have important consequences for biological integrity and biodiversity. All aquatic organisms move within and among FEM components, but differ in the mode, frequency, distance, and timing of their movements. These movements allow biota to recolonize habitats, avoid inbreeding, escape stressors, locate mates, and acquire resources. Cumulatively, these individual movements connect populations within and among FEMs and contribute to local and regional diversity, resilience to disturbance, and persistence of aquatic species in the face of environmental change. Thus, the biological connections established by movement of biota among streams, wetlands, and downstream waters are critical to the ecological integrity of these systems. Future research will help advance our understanding of the movements that link FEMs and their cumulative effects on downstream waters.

“…In 2001, however, an interpretation of the CWA by the U.S. Supreme Court ( Solid Waste Agency of Northern Cook County v. United States Army Corps of Engineers, 2001; 531 U.S. 159) invalidated the “Migratory Bird Rule” as a sole determinant for CWA jurisdiction. This ruling effectively eliminated protections for certain classes of wetlands, notably those geographically isolated from navigable waters, which are often the wetlands of greatest value to breeding ducks (Petrie et al , van der Valk and Pederson ). Fortunately, conservation provisions of landmark agricultural policy (i.e., U.S. Farm Bills) have provided since 1986 an important safety net by discouraging the drainage or conversion of remaining wetlands to agricultural uses, with a few notable exceptions (e.g., playa wetlands of the U.S. Great Plains [Smith ]).…”

Waterfowl conservation in North America provides an example of an abundant wildlife resource that was driven to alarmingly low levels as a result of unregulated exploitation of its populations and habitats, but which has since recovered because of cooperative efforts across multiple countries. Waterfowl conservation in North America began in earnest during the late 19th and early 20th centuries and has developed through international treaties and national policy as well as regional partnerships and supporting efforts of private landowners. In recent years, significant accomplishments have been realized through public-private partnerships that use local knowledge and engagement with stakeholders to develop conservation programs that are compatible with landowner interests and existing farming or ranching operations. Through the presentation of case studies from across North America, we demonstrate there exists no single 'best' program or framework for conserving waterfowl habitat on private lands, although a common denominator for success is robust support from an energized and resourceful partnership. Financial incentives provided a positive encouragement for participation, but private land programs will be most effective long term when they explicitly incorporate the needs of private landowners and generate benefits beyond provision of wildlife habitat. Successful conservation of waterfowl populations into the future will require a suite of programs and strategies and will hinge on our ability to develop conservation solutions that provide mutual benefits to waterfowl and an increasingly diverse private-landowner base.

“…North and South Dakota escaped large‐scale installation of drainage tile until the early 2000s. The reasons why large numbers of landowners have recently tiled their fields or are awaiting approvals are several and include: a wet climatic cycle (Werner et al ., ), the ability of tile drainage to improve crop yield (Schwab et al ., ; Kanwar et al ., ), rising commodity prices (Leibtag, ; U.S. Department of Agriculture, ), and recent changes to federal policies regarding wetland protection (Van der Valk and Pederson, ).…”

“…While purposeful drainage of wetlands continues today, Farm Bill program participants must adhere to “Swampbuster” provisions in the Food Security Act of 1985. However, in the early 2000s legal decisions weakened some of the additional protection provided by the Clean Water Act (Van der Valk and Pederson, ). Johnston () and Wright and Wimberly () reported sharp increases in the rates of wetland and grassland conversion into cropland in the PPR in the past decade when grain commodity prices soared to record levels.…”

Modeling the Effects of Tile Drain Placement on the Hydrologic Function of Farmed Prairie Wetlands

The early 2000s saw large increases in agricultural tile drainage in the eastern Dakotas of North America. Agricultural practices that drain wetlands directly are sometimes limited by wetland protection programs. Little is known about the impacts of tile drainage beyond the delineated boundaries of wetlands in upland catchments that may be in agricultural production. A series of experiments were conducted using the well‐published model WETLANDSCAPE that revealed the potential for wetlands to have significantly shortened surface water inundation periods and lower mean depths when tile is placed in certain locations beyond the wetland boundary. Under the soil conditions found in agricultural areas of South Dakota in North America, wetland hydroperiod was found to be more sensitive to the depth that drain tile is installed relative to the bottom of the wetland basin than to distance‐based setbacks. Because tile drainage can change the hydrologic conditions of wetlands, even when deployed in upland catchments, tile drainage plans should be evaluated more closely for the potential impacts they might have on the ecological services that these wetlands currently provide. Future research should investigate further how drainage impacts are affected by climate variability and change.
