Surveys were conducted at wetlands within townships selected in a stratified random procedure, with strata based on landscape composition of agricultural cropland and total area of wetlands. We explored shorebird sensitivity and adaptive capacity to climate change by combining historic distribution data with multi-scale habitat selection models and comparing shorebird wetland selection between a historic dry and wet year. 2002 2011 ground condition Complete None planned -103.93066406250001 -94.43847656250001 49.15296965617039 42.87596410238256 U.S. Prairie Pothole Region ISO 19115 Topic Category farming biota inlandWaters None Prairie Pothole Region stopover habitat USGS Thesaurus climate change birds migration (organisms) Marine Realms Information Bank (MRIB) keywords wetlands USGS Metadata Identifier USGS:5a7c9798e4b00f54eb231afb Common geographic areas North Dakota South Dakota None.

We selected 96 townships using a stratified random sample based on median proportions of wetland area (> 8% = “high”; < 8% = “low”) and cropland (> 60% = “high”; < 60% = “low”) land cover classes within the U.S. prairie pothole region study area. Surveyors drove multiple roads within townships, stopping at and surveying wetlands or portions of wetlands within 200 meters of the road. To characterize local habitat conditions at wetland sites, we estimated current wet surface area of each wetland using either an ocular estimate of wetland acres or by describing the percentage of the wetland holding water. Our estimates were compared to a National Wetlands Inventory (NWI) map of the wetland before deriving the final value along with the NWI wetland area information (see GIS Landcover below). In addition, we recorded: 1) the surrounding landscape cover type based on assessing the primary cover type in a 500-m radius of the wetland: tilled cropland, pasture, grassland, other cropland, hayland, trees/forest, and farm (barns, outbuildings, etc.); and 2) the primary cover class surrounding the periphery of the wetland out to 30 m according to the same classes (from a GIS landcover layer in 2002 and from ocular estimates in 2011). Wetlands with a linear form such as a ditch, river, or creek were not included in our analysis due to the low proportion of these wetlands in the dataset and low shorebird use of these wetlands. 20171010 To describe features of surveyed wetlands and surrounding landscape, we extracted data from spatial layers in ArcMap 10.2 (ESRI, Redlands, California). To describe the length of wetland shoreline surveyed, we first used the National Wetlands Inventory (NWI) layer to extract the periphery length of the mapped wetland. We then calculated the periphery of each wetland within the survey distance (200 m) of roads by buffering the road and clipping to create a new wetland layer within that distance. We also used the NWI layer to extract information on wetland regime: temporary, seasonal, semipermanent, or lake 20171010 shorebird.2002.2011.csv Comma Separated Value (CSV) file containing data.
