WBPHS_Stratum_Areas.csv is a table that lists the area measurements (in square miles) for strata 1-12, as measured and adopted by survey designers in 1974. These measurements are used by MBM-AK in analyses to produce bird abundance estimates by species and stratum.

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...
Funding will be provided to Save the Bay, an organization based in Rhode Island that is developing cutting-edge runnelling techniques that are improving thousands of acres of marshes across the region. Save the Bay’s Restoration Director works with partners throughout the Northeast region, and regularly hosts partners in the field and via webinars to share tips and lessons learned on implementing these techniques. Funds will allow her to provide greater regional support in the form of training salt marsh practitioners and sharing evaluation results of runnelling effectiveness that will inform work throughout the Northeast. In addition to these funds, an additional $30,000 of Coastal program funding will supplement...

The Alaska Trumpeter Swan Survey used U.S. Geological Survey (USGS) 1:63,360 scale quadrangle maps as sampling units (plots). USGS identifies each 1:63,360 map with a combination of two identifiers: 1) the 1:250,000 quadrangle in which it occurs, and 2) the 1:63,360 quadrangle map itself. Similarly, in the swan survey files, the 1:63,360 map is identified by the combination of the “Map” and “Quad” fields. The Map field identifies the 1:250,000 quad by its USGS numeric code; the Quad field identifies the 1:63.360 map by its appropriate letter-number. The USGS numeric 1:250,000 map codes also have associated USGS text labels (names). Map_Codes.csv defines the map names that are associated with the USGS numeric codes....

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.

This is a comma delimited text file of the bird observations for the Arctic Coastal Plain survey. These observations have undergone an extensive quality control process that is ongoing and corrected several errors in the source data. Point observation of birds are given in coordinate reference system EPSG:4326 and are accurate only to +/- 500m. The field "Year" gives the calendar year that the survey was flown, "Stratum" gives the transect density strata name, "NavTransect" gives the transect identifier used for navigation by the pilot (this is not necessarily the same as the design transect), and "Obs_Type" is the social group (single, pair, etc.) of the bird observation, "Num" is the number of observation of...

The Yukon-Kuskokwim Delta (YKD) Aerial Breeding Pair Survey provides data on the spring abundance of targeted waterfowl species nesting on the YKD coastal zone in western Alaska. This region supports millions of waterbirds that comprise one of the largest and most important waterfowl breeding grounds in North America, including species of concern such as the red-throated loon (Gavia stellata), emperor goose (Chen canagica), Pacific black brant (Branta bernicla nigricans), common eider (Somateria mollissima), black scoter (Melanitta nigra), long-tailed duck (Clangula hyemalis), and the threatened spectacled eider (Somateria fischeri). The YKD goose, swan, and crane survey was first implemented in 1985 to monitor...

This file contains information pertaining to the survey plot including date and time of surveyed, survey conditions, plot location, and ecological and biological conditions of the survey plot. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein.
