The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...
In this data set, records (rows) represent GPS locations of ducks marked with telemetry in California and whether locations were overlapping (within 300 m of) locations of marked ducks in other consecutive years (2015-16, 2016-17, and 2017-18) during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in tables E3 and E4 to compare overlap of duck locations between consecutive years to investigate interannual habitat stability in relationship with drought, habitat management (daytime roosts and night feeding sites), and in two regions (Suisun Marsh and California...

This data file is in long format, comprising time series of hunter abundance and behavior and duck abundance. Hunter information varies by administrative flyway (Mississippi and Central), whereas duck population abundance is summarized for both the Prairie Pothole Region and the continent. Duck information for the Prairie Pothole Region is for the U.S. portion only (Strata 41-49 of the May waterfowl survey) and for 12 duck species, mallard, American wigeon, blue-winged teal, canvasback, gadwall, lesser and greater scaup, green-winged teal, northern pintail, northern shoveler, redhead, ring-necked duck, and ruddy duck.
In this data set, records (rows) represent the distance between primary daytime roosts and night (feeding) locations of ducks marked with telemetry in California in years 2015-16, 2016-17, and 2017-18, during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in figures E3 and E4 to compare distances moved among months, years, and for two regions (Suisun Marsh and California except Suisun Marsh). Matchett and company examined the effect of drought on distributions of ducks by evaluating differences in spatial distributions of duck locations within and among...
We used Point Blue Conservation Science's dynamic open-water dataset of water distribution and our telemetry data for duck locations to develop frequently updated habitat maps for the Central Valley and Suisun Marsh in California during October-March of 2014-15 through 2017-18. Telemetry data additionally was used to compare performance of each of three series of habitat maps produced. To create this tabular dataset, we intersected telemetry locations for ducks (vector point data) with habitat maps (raster mosaics) in a Geographic Information System (GIS) and attributed duck locations with map pixel values representing habitat, non-habitat, or unclassified (if data were missing). To develop maps of waterfowl habitat,...
