Interactions of consolidation drainage and climate on water-level dynamics, wetland productivity, and waterbirds

In the Prairie Pothole Region (PPR) wetland plant, invertebrate, and waterbird productivity are primarily driven by water-level dynamics in response to climate cycles. Large proportions of wetlands in the PPR have been drained, often consolidating water from smaller to larger-interconnected wetlands. This project will examine whether large basins that receive inflow from consolidation drainage have reduced water-level dynamics in response to climate cycles than those in undrained landscapes, resulting in relatively stable wetlands that have lower densities of invertebrate forage for ducks and shorebirds. We will also include a sample of wetland historically used by piping plovers to assess the threat of consolidation...

Assessment of agricultural subsurface drainage tile on wetland hydrology and ecosystem services in the Prairie Pothole Region

This project contains related research product materials for the assessment of agricultural subsurface drainage tile systems on wetland hydrology in the Prairie Pothle Region. Materials included: downloadable files of drainage tile locations based on tile drainage permits collected from state, county, and local agencies in North and South Dakota. These files can be used to develop a spatial depliction of tile systems at the quarter-quarter level of a section of the TRS system. See associated metadata for information about the data included in the files.
