Conant et al. (2002) present the results of trumpeter swan censuses conducted by the U.S. Fish and Wildlife Service in Alaska between 1968 and 2000. Full citation: Conant, B., J.I. Hodges, D.J. Groves, and J. G. King. 2002. Census of trumpeter swans on Alaskan nesting habitats, 1968-2000. Waterbirds: The International Journal of Waterbird Biology, v. 25, Special Publication 1: Proceedings of the Fourth International Swan Symposium 2001, pp 3-7.

SEAK_Nearshore_Survey_Area.gpkg is a geopackage that contains a polygon layer of the survey area for the summer and winter Southeast Alaska Nearshore Waterbird Surveys. All of the shoreline in the layer was surveyed, including rocks and small islets.

This dataset, SummerSimplified.csv, contains the bird and marine mammal data collected during the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey, edited for quality-control (QC) purposes. During the QC process, observations of the same species that were less than 0.3 nautical miles apart were merged. Species codes of certain species were changed to a group code, e.g., scoter-specific species (BLSC, SUSC, WWSC) to SCOT. Species that were considered inadequately surveyed due to detection issues or inappropriateness of the survey design were removed.

The daily flight tracks of the 1997-2002 aerial winter Southeast Alaska Nearshore Waterbird Survey were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the plane’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the aircraft’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks thus may include the aircraft’s flight to and from the airport base. Note that the 1997 flight tracks are missing.The track files in all years except 2002 are named TRMMDDYY_AIR.csv,...

The Alaska Swan Survey Protocol was first developed by MBM-AK (James G. King, retired) in the 1960s to describe a standardized method of conducting aerial swan surveys in Alaska. Documentation of the protocol was last updated in 2007. All the swan survey data in the Alaska Swan Database were collected using this protocol.

From 1981 to 2009, MBM-AK collaborated with its partner, U.S. Forest Service Cordova Ranger District, to conduct spring nesting and late-summer trumpeter swan surveys on the Copper River Delta, Alaska. An annual summary report was produced by MBM-AK. As of the date that this metadata was written, only the 2004-2009 reports were available in digital format and archived in the FWS Alaska Regional Data Repository (AK_Swan_Database project). All the reports in paper format are available upon request from MBM-AK (see contact information elsewhere in this metadata).

The Alaska Trumpeter Swan Survey data files (AK_TRUS_Data_YYYY.csv, where YYYY = survey year) include a field called “Contrib,” which indicates the organization that collected the data. Each organization is identified by a numeric code. Contrib_Codes_AK_TRUS_Survey.csv defines the data-contributor codes that were entered in the Contrib field.

This GeoPackage, WBPHS_Strata.gpkg, contains the approximate WBPHS survey design stratum boundaries for Alaska and Old Crow Flats, Yukon Territory (i.e., strata 1 through 12). Strata 1-12 were adopted in 1974 and are applied retroactively to all years of data during analyses. The strata and measurements in this GeoPackage are not accurate, because MBM-AK has been unable to locate clear, unequivocal documentation of the exact boundary delineations that were measured and adopted in 1974. Multiple versions of historical paper maps and blueprints exist on which survey designers drew stratum boundaries; however, the maps do not include documentation on what the drawn boundaries represent, i.e., whether they were draft...
