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...

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...
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 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...
Protocol documents providing detailed information on data collection methods including 1) Saalfeld, S. T., H. R. Gates, S. C. Brown, K. M. Sowl, B. A. Andres, J. A. Johnson, J. E. Lyons, B. J. McCaffery, and R. B. Lanctot. 2022. Survey Protocol for the Arctic Program for Regional and International Shorebird Monitoring (PRISM). Version 1.0. U.S. Fish and Wildlife Service, Division of Migratory Bird Management, Anchorage, AK and 2) annual field protocol documents.
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...
This file provides deployment and retrieval information for acoustic monitors placed on PRISM plots in 2022 including location, habitat, and date and times of deployment and retrieval. 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 collection of files includes audio files downloaded directly from acoustic monitors in 2022, providing sound recordings of shorebird PRISM plots. 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. Files are organized in folders by 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, individual birds may have went undetected within survey plots, as detectability was likely less...

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...
