Data used to estimate models relating climate and land cover to wetland densities. Data derived from historical climate data, estimates of hydrological processed based on the Variable Infiltration Capacity model, National Wetlands Inventory, and National Land Cover Database (2006 version). Wetland densities based on observations from the Waterfowl Breeding Population and Habitat Survey.

Projected wetland densities under 10 different climate models and 3 land use and land cover scenarios. This file contains projected wetland densities under each combination of land use and climate.

A study was conducted to assess the efficacy of drainage setbacks for limiting effects to wetlands in the Prairie Pothole Region, USA. Surface-water levels, along with primary components of the wetland water balance, were monitored at four wetland catchments over 3 years. During the second year of the study, subsurface drainage systems were installed in two of the wetland catchments using drainage setbacks, and the drainage discharge volumes were monitored. A catchment water-balance model also was used to assess the potential effect of subsurface drainage (i.e., reduced precipitation runoff) on wetland hydrology, and to assess the efficacy of drainage setbacks for mitigating these effects. These data directly support the associated publication “A case study examining the efficacy of drainage setbacks for limiting effects to wetlands in the Prairie Pothole Region, USA” which is referenced within the Metadata.

This dataset provides a compilation of the wetland characteristics, water quality, and aquatic macroinvertebrate community metric data collected from 159 wetlands in the Prairie Pothole Region of Montana and North Dakota.

This data release encompass numerous studies examining soil properties and greenhouse gas fluxes of Prairie Pothole Region (PPR) wetland catchments. The PPR is one of the largest wetland ecosystems in the world, encompassing approximately 770,000 square kilometers of the north-central U.S. and south-central Canada, with the U.S. portion including parts of Iowa, Minnesota, South Dakota, North Dakota, and Montana. The data included in this release span a 19-year period (1997–2016) and represent a diversity of studies ranging from localized (e.g., wetland catchments and complexes) to region-wide efforts that span the PPR’s climate and land-use gradient. Data from individual wetland catchments encompass a variety of wetland classes ranging from small, ephemerally-ponded wetlands to large, shallow lakes. Although study designs and methodologies differ slightly among the studies, the overarching methods are comparable and allow the data to be combined into a single data release. The data release consists of combined datasets (i.e., all studies) for soils, greenhouse gases, topography, water chemistry, weather, and covariate or explanatory variables such as water depth, soil moisture, and temperature. A majority of the studies also present data from the entire wetland catchment, with data collected from numerous landscape positions along transects spanning from the wetland center to the catchment boundary. Sample frequency among the studies ranges from a single site visit per year, to season-long, biweekly sample events across multiple years.
