Interactions of consolidation drainage and climate on water-level dynamics, wetland productivity, and waterbirds Completed
Northern Prairie Wildlife Research Center (NPWRC) recently completed a project aimed at understanding the impacts of wetland drainage on wetlands that receive drainage water. The biological communities of prairie pothole wetlands evolved in a hydrologically dynamic system due to periodic wet and dry conditions. NPWRC research indicates that relative to wetlands in undrained landscapes, wetlands that receive consolidation drainage water drawdown less during dry conditions and progressively get larger and stabilize at their spill point during wet conditions. The implications of this water-level increase and eventual stabilization is that it reduces biological productivity and favors invasive species. These results have informed conservation efforts toward watershed-oriented restoration and protection of wetlands in the prairie pothole region.

Is consolidation drainage an indirect mechanism for increased abundance of cattail in northern prairie wetlands?
In the Prairie Pothole Region of North America, disturbances to wetlands that disrupt water-level fluctuations in response to wet–dry climatic conditions have the potential to alter natural vegetative communities in favor of species that proliferate in stable environments, such as cattail (Typha spp.). We evaluated the effect of water-level dynamics during a recent fluctuation in wet–dry conditionAuthorsMark T. Wiltermuth, Michael J. AnteauPrerequisites for understanding climate-change impacts on northern prairie wetlands
The Prairie Pothole Region (PPR) contains ecosystems that are typified by an extensive matrix of grasslands and depressional wetlands, which provide numerous ecosystem services. Over the past 150 years the PPR has experienced numerous landscape modifications resulting in agricultural conversion of 75–99 % of native prairie uplands and drainage of 50–90 % of wetlands. There is concern over how andAuthorsMichael J. Anteau, Mark T. Wiltermuth, Max Post van der Burg, Aaron T. PearseA Bayesian approach for temporally scaling climate for modeling ecological systems
With climate change becoming more of concern, many ecologists are including climate variables in their system and statistical models. The Standardized Precipitation Evapotranspiration Index (SPEI) is a drought index that has potential advantages in modeling ecological response variables, including a flexible computation of the index over different timescales. However, little development has been mAuthorsMax Post van der Burg, Michael J. Anteau, Lisa A. McCauley, Mark T.

Many waterbird species utilize a diversity of aquatic habitats; however, with increasing anthropogenic needs to manage water regimes there is global concern over impacts to waterbird populations. The federally threatened Piping Plover (Charadrius melodus; hereafter plovers) is a shorebird that breeds in three habitat types in the Prairie Pothole Region of North Dakota, South Dakota, and Canada: riAuthorsLisa A.

The important ecosystem functions wetlands perform are influenced by land-use changes in their surrounding uplands and thus, identifying the upland area that flows into a wetland is important. We provide a method to define wetland catchments as the portion of the landscape that flows into a wetland; we allowed catchments to be nested and include other wetlands and their catchments, forming a hydroAuthorsLisa A.
