This is the GeoPackage (“TMG_AdditionalArea_Trans.gpkg”) that contains the layer (“main.TMG_Area_Trans”) depicting the spatial extent of the four Additional Survey Area transects that are surveyed during the annual MBM-AK TLSA molting goose aerial surveys. This GeoPackage (NAD83; ESPG: 3338) was created by Michael Swain in August 2021 and subsequently emailed to Maggie Harings. It includes waterbody units, waterbody types, and waterbody perimeter as well as their areas.Transects do not exist for Cape Simpson as this area is adequately assessed by conducting aerial surveys for lakes only. Piasuk River Delta area is surveyed using a combination of aerial lake surveys and transects. Colville River Delta and Atigaru...

The WBPHS is conducted by flying an aircraft along a set of segment lines. (One or more contiguous segments comprise a transect.) The geographic coordinates in WBPHS_Segment_Endpoints.csv represent the beginning and ending points of the segment lines in Alaska and Old Crow Flats (Yukon Territory) strata 1-12. The point coordinates in this file have been incorporated into various products (e.g., a GPS waypoints file) to aid in survey-flight navigation. The coordinates are in decimal degrees, WGS84 datum.The set of segments contained in this file was established in 1964. In the years 1957-1963, the survey design included many, but not all, of these segments. Additional segments were flown in some or all years during...

In many areas surveyed during the North American WBPHS, ground surveys are conducted in conjunction with the aerial surveys to derive annual visibility correction factors (VCFs) for the aerial survey crews, which are used during analyses to adjust for detection bias. Due to the remoteness of strata 1–12, ground surveys are not conducted there. Instead, a set of fixed VCFs by species and basic habitat type (strata 1–7 = boreal forest; strata 8–11 = tundra; stratum 12) are used. The fixed VCFs that were used through 1991 were derived from work done in WBPHS prairie strata. During the years 1985–1991, efforts were made by the FWS Division of Migratory Bird Management-Alaska Region (MBM-Alaska) to develop more appropriate...

Observer-specific population indices for the USFWS Region Migratory Bird Management Arctic Coastal Plain study area. The survey consists of low-level aerial observations of waterfowl on a stratified strip transect design. The resulting data frame is several indices separated by observer and calculated using a standard ratio estimator. These data are output from the R package AKaerial and are also available within that package, see https://github.com/USFWS/AKaerial. The data used to produce these estimates contain known errors. Many but not all of these errors are corrected within the R package AKaerial. These data are presented for historical purposes only. See https://github.com/USFWS/ACP-Mapping and comments within...

Between September and November each year, nearly the entire world population of Pacific black brant (Branta bernicla nigricans) stages at Izembek Lagoon and surrounding estuaries (hereafter: Izembek Complex). The Izembek Complex is a unique area of protected brackish waters, supporting one of the world’s largest eelgrass beds and a diverse array of wildlife. The Alaska Fall Brant Survey has been conducted annually since 1976 in late-September through October, to provide an index of abundance for the entire post-breeding Pacific black brant population (Branta bernicla nigricans), while secondarily, providing annual fall population indices for cackling geese (Branta hutchinsii), emperor geese (Anser canagicus), and...

This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include Tiny Tag number, site, year, and nest ID..ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings...

Collection of photographs taken during PRISM field work on the Yukon Delta. Photos include those taken of habitat within rapid survey plots (usually taken at the northwest corner of the rapid survey plot boundary), other photos taken within survey plots, completed datasheets, and by crew members.Directories include YKD_PRISM_plot_photos, YKD_PRISM_datasheet_photos, YKD_PRISM_other_plot_photos, and YKD_PRISM_crew_photos.A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).Much of these data have been published in Lyons, J.E., S.C.

The Waterfowl Breeding Population & Habitat Survey (WBPHS) has been conducted annually since 1955 (1957 in Alaska) by the U.S. Fish and Wildlife Service (FWS) and Canadian Wildlife Service to estimate the spring abundance of targeted waterfowl species in their principal breeding areas of North America. The survey results are used to establish annual hunting regulations in the United States and Canada, monitor population trends, and inform various conservation and management decisions at the state, flyway, and continental levels.The Waterfowl Program in the FWS Division of Migratory Bird Management-Alaska Region (MBM-Alaska) is responsible for surveying strata 1–12 of the WBPHS during May to June of each year (i.e.,...

This is an incomplete collection of track files produced during the MBM-AK TLSA molting goose survey flights. They reference latitude, longitude, and time in total seconds in the day. These files are called by R code (‘TMGSurvey_Master_2019.Rmd’ located in ‘GitHub_Annual_Report_Code’). Following review of this code, it appears as though these transcripts were not ultimately used in any way. Please consult ‘TMGSurvey_Master_2019.Rmd’ for additional context. Track file naming format is as follows: ‘TR[date][firstInitialLastNameOfObserver].csv’; HWilson refers to Heather Wilson while BShults refers to Brad Shults.
