Wetlands Retention and Optimal Management of Waterfowl Habitat under Climate Change

Journal of Agricultural and Resource Economics, 2014
We develop a positive mathematical programming model to investigate the impact of climate change on land use in the prairie pothole region of western Canada, with particular focus on wetlands retention. We examine the effect of climate change and biofuel

Assessment of USGS DEMs for modelling pothole inundation in the prairie pothole region of Iowa

Geocarto International, 2019
This study aims to compare inundation in two potholes using Annualized Agricultural Non-Point Source Pollution model (AnnAGNPS) with three Digital Elevation Models (DEMs): a 1 m DEM prepared from t...

Comparison of aquatic invertebrate communities in near-shore areas with high or low boating activity

Journal of Freshwater Ecology, 2019
Lakeshore areas provide important habitat for aquatic invertebrates in shallow lakes. However, these zones are prone to anthropogenic disturbances that include shoreline development, urbanization, nutrient inputs, agricultural and(or) recreational use ...

Distribution of priority grassland bird habitats in the Prairie Pothole Region of Canada

Avian Conservation and Ecology, 2018
Grassland ecosystems and the species that rely on them are one of the most urgent habitat conservation concerns in North America. Fundamental to any landscape conservation efforts is the identification of priority habitats to help target management ...

Landscape composition, climate variability, and their interaction drive waterfowl nest survival in the Canadian Prairies

Ecosphere, 2022
For upland‐nesting ducks that rely on grassland and wetland habitats in landscapes characterized by human alteration and a strongly fluctuating climate, information on how landscape composition interacts with climate is needed to better understand the ...

A watershed classification approach that looks beyond hydrology: application to a semi-arid, agricultural region in Canada [PDF]

Hydrology and Earth System Sciences, 2019
Classification and clustering approaches provide a means to group watersheds according to similar attributes, functions, or behaviours, and can aid in managing natural resources.

Use of macroinvertebrates to identify cultivated wetlands in the Prairie Pothole Region [PDF]

Wetlands, 2001
We evaluated the use of macroinvertebrates as a potential tool to identify dry and intensively farmed temporary and seasonal wetlands in the Prairie Pothole Region. The techniques we designed and evaluated used the dried remains of invertebrates or their egg banks in soils as indicators of wetlands. For both the dried remains of invertebrates and their

Seasonal patterns and key chemical predictors of dissolved greenhouse gases in small prairie pothole ponds

FACETS
Shallow ponds can provide ideal conditions for production of greenhouse gases (GHGs) carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), and thus are important to include in global and regional GHG budgets.

Additionality in Grassland Easements to Provide Migratory Bird Habitat in the Northern Plains

Journal of Agricultural and Resource Economics, 2017
Native grassland in the Prairie Pothole Region (PPR) is important habitat for migratory birds, particularly ducks. Much of this grassland is at risk for conversion to cropland. Permanent easements, managed by the U.S.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

Wildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...
