We used publically available data on duck breeding distribution and recently compiled geospatialdata on upland habitat and environmental conditions to develop a spatially explicitmodel of breeding duck populations across the entire Prairie Pothole Region (PPR). Ourspatial population models were able to identify key areas for duck conservation across thePPR and predict between 62.1 – 79.1% (68.4% avg.) of the variation in duck counts by yearfrom 2002 – 2010. The median difference in observed vs. predicted duck counts at a transectsegment level was 4.6 ducks. Our models are the first seamless spatially explicit modelsof waterfowl abundance across the entire PPR and represent an initial step toward jointconservation...

Rapid expansion of cropland threatens grassland ecosystems across western North America and broad-scaleplanning can be a catalyst motivating individuals and agencies to accelerate conservation. Sprague’s Pipit(Anthus spragueii) is an imperiled grassland songbird whose population has been declining rapidly in recent decades.Here, we present a strategic framework for conservation of pipits and their habitat in the northern GreatPlains.We modeled pipit distribution across its million-km2 breeding range in Canada and the U.S.We describefactors shaping distribution, delineate population cores and assess vulnerability to future grassland losses. Pipitsselected landscapes with a high proportion of continuous grassland...

Wetland hydroperiod, the length of time water is available in wetlands, is particularly sensitive to changes in precipitation, temperature and timing due to climate variation. Truncated hydroperiod has major implications for wetland-dependent species (e.g., waterfowl) and human water allocation. Researchers aim to link hydroperiod to current climatic variation and use this relationship to predict wetland hydroperiod across the moisture gradient from sage steppe to grasslands.

The Plains and Prairie Potholes Landscape Conservation Cooperative (PPPLCC) encompasses over 1.2 million square kilometers in 3 Canadian Provinces and 7 US States. A main objective of the PPPLCC is to facilitate improved scientific understanding of the effects of broad-scale environmental stressors on plant and animal resources across this extensive region. Geographic Information Systems (GIS) promote broad-scale understanding by providing support for rigorous study, inventory, assessment, and monitoring of the amount and condition of habitat across extensive geographies. Development of coherent, validated GIS data for the PPPLCC region was therefore identified as an important initial step toward accomplishing the...

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...
