The Souris River watershed spans more than 23,000 square miles (61,000 square kilometers) across Saskatchewan, North Dakota and Manitoba. The funding will support a cross-jurisdictional study led by Ducks Unlimited, Inc., Ducks Unlimited Canada, and Province of Manitoba researchers that will combine current and historic wetland inventories and examine water quality trends across watersheds with varying levels of wetland cover. Non-point source pollution from the Souris River watershed has been known to impact water quality throughout the watershed including the adjoining Assiniboine River and Lake Winnipeg.

Wetland hydroperiod, the length of time water is available in wetlands, is sensitive to changes in precipitation, temperature and timing due to climate variation. Truncated hydroperiod has major implications for wetland-dependent species (e.g., waterfowl, amphibians) and human water allocation (PPP LCC Need 1). To characterize wetland hydroperiod in the Plains and Prairie Pothole Region, we first identify location and hydroperiod of wetlands using field-based and remotely sensed training data (RapidEye, Landsat). We define hydroperiod as wetland ephemerality, where ephemerality represents the persistence of a wetland across the growing season. We then link hydroperiod to climatic variation by relating climate time-series...

WWF and partners will assess the probability of grasslands being converted to cropland in the Northern Great Plains by analyzing land characteristics (e.g. soil properties conducive to specific crops), climate variables (e.g. rainfall, temperature before and during the growing season) associated with different land uses. The conversion risk analysis will produce a statistical model that explains which factors drive grassland conversion and can predict grassland conversion risk across the NGP- at five and ten years from present. Likely impacts from climate change on suitability of lands for different crops will be incorporated by simulating conversion risks unde alternative future climate scenarios at 20 and 40...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
