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...

These data represent reproductive ecology characteristics for 4 species of mature female turtles captured at Elephant Butte Reservoir on the Rio Grande River in New Mexico, during two field survey periods in June 2012 and 2013. Data were collected on female reproductive ecology including clutch size, egg size, timing of egg production, and the percentage of reproductive females using X-radiography. The purpose of these data are to add to the deficient information on the reproductive ecology of four turtle species at the Elephant Butte Reservoir on the Rio Grande and Black River in New Mexico. Data contained in this worksheet were analyzed to determine clutch and egg sizes for four native species of turtles (Apalone...
The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

Distribution of Alcid habitat in coastal British Columbia showing relative abundance (RA) by season and overall relative importance (RI). RI is based on project region and not on the province as a whole. British Columbia has been collecting coastal resource data in a systematic and synoptic manner since 1979. Resource information is collected using peer-reviewed provincial Resource Information Standards Committee which include standards for data management and analysis
Collection of photographs taken during PRISM field work on the Arctic National Wildlife Refuge. Photos include those taken of habitat within rapid survey plots (usually taken at the northwest corner of the rapid survey plot boundary), completed datasheets, and by crew members. Directories include ANWR_PRISM_plot_photos, ANWR_PRISM_datasheet_photos, ANWR_PRISM_other_photos. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including...

WFowl01Vol1 depicts known waterfowl habitat areas in twenty-six environmentally sensitive areas along the Arctic, Western and Southwestern coast of Alaska. This data are a combination of duck and geese data digitized from mylar original maps from the Alaska Habitat Management Guides (1985) and updated bulelines from area biologists (1997 and 2001). Data for the following categories were captured: Known spring concentrations - areas where concentrations of one or more species of waterfowl have been observed during spring migration for more than one year. Known nesting concentrations - areas where concentrations of one or more species of nesting waterfowl have been observed during more than one year. Known fall concentations...

Robust assessments of nesting periods and durations for many grassland-nesting birds in the Great Plains are lacking. The timing of management practices (e.g., grazing, haying, mowing, burning) will invariably have different benefits or impacts to different guilds of birds. Our goal is to inform decisions about timing of management practices with research to provide an improved quantification and understanding of contemporary nesting season patterns for grassland birds. Results from this project could aid program managers through improved assessments of tradeoffs from the timing of management actions for various priority birds in the Great Plains.

This dataset includes a polygon vector shapefile illustrating the location of rapid survey plots surveyed in the Arctic Refuge as part of the Program for Regional and International Shorebird Monitoring (PRISM). This dataset provides the geographical location of survey plots that can be linked to the data collected in the field via the PlotID field. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species,...

This file includes R code to select annual sampling units for PRISM surveys on the Arctic National Wildlife Refuge using a stratified random sampling approach.We used the Generalized Random Tessellation Stratified (GRTS) procedure (Stevens and Olsen 2004) to obtain a spatially balanced sample of 108 plots within each of the four strata to be surveyed. To determine how to allocate the 108 plots among strata, we initially used shorebird densities and variances (averaged across species) presented in Brown et al. (2007), but adjusted these values to include additional upland and riparian plots. Final allocation included 45 wetland plots, 35 moist plots, 12 upland plots, and 16 riparian plots. We also selected an additional...
Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...

This file provides data pertaining to bird nests found during surveys on rapid plots and includes information for each nest such as date found, species, location, and egg floatation data. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including differences in species, habitat, time-of-year, weather conditions, survey effort, and individual surveyor. The data providers have invested considerable effort in QA/QC, but it is possible...
This dataset includes a polygon vector shapefile that provides information pertaining to the sampling universe (i.e., the potential sampling units within the study area) from which rapid surveys were selected. To delineate sampling units (i.e., survey plots), we overlaid the 1002 Area of the Arctic NWR with a grid of 16 ha plots (400 × 400 m each) in ArcGIS 10 (Environmental Systems Research Institute, Redlands, CA, USA; Alaska Albers Equal Area Conic NAD83). Given the logistical constraints for obtaining permission to access private lands within the Arctic NWR, we limited our spatial sampling to public lands administered by the U.S. Fish and Wildlife Service using the National Wildlife Refuge Land Status Data for...
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.

Using automatic recorders allows for a consistent, unbiased, and regular data collection during the whole summer and will be used to verify PRISM survey data and determine if shorebirds can be monitored remotely using audiorecording devicies. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than...
This file provides data collected during rapid surveys, with each record pertaining to a unique sighting of a given shorebird or waterfowl species within a survey plot including information on species, number of individuals, and breeding status. Therefore, each survey plot may have multiple records when more than one sighting occurred. Each record also contains information pertaining to the survey plot including date and time of survey, survey conditions, survey location, and ecological and biological conditions of the survey plot. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally,...
This file provides data pertaining to occurrence (i.e., presence) of all bird species encountered during rapid surveys. Each record pertains to a unique species observed on a given plot. Therefore, survey plots may have more than one record when more than one species was observed on a given plot. Each species is listed only once per plot and includes species seen or heard both inside and outside (usually within 200 to 300 meters) plot boundaries (including species counted during PRISM surveys - see ‘ANWR PRISM rapid survey data’ and during nest survival surveys - see ‘file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_003_ANWR_nest_survival’). These data do not represent all locations within the Arctic National Wildlife...
