Waterfowl Breeding Population Habitat Survey Standard Operating Protocol Update 04-21-2022 The standard operating procedures (SOP) document for the overall WBPHS, including the Alaska strata, was updated by USFWS Division of Migratory Bird Management Branch of Migratory Bird Surveys on 21 April 2022. This SOP applies to all survey crews, including Alaska’s.

The log files were produced when the original (“raw”) transcribed data were run through the QC process via the “Greenlight” script within the R package “AKaerial” (available at github.com/USFWS/AKaerial). The log files describe any changes that were made to the raw transcribed data during the QC process. There is one log file for each QC transcribed data file: WBPHS_YYYY_QCLog_OOO.html, where YYYY=Year and OOO=Observer initials.

Plots in this data set are linked through the combination of plot number and year provided in this file. Plot search history indicates if a plot was searched for nests. Plot shape and area has varied through time. After 1985, plot were selected by stratified random sampling, and after 1998 by simple random sampling from the area defined in ‘YKD Nest Plot Study Area Boundary.’ Plot shape has also varied but after 1998 was generally 1/4 by 1/2 mile.

The original transects were imported to this SQLite database structure and saved as individual polylines named according to the year they were created (e.g., “main.YK_1985_Trans,” “main.YK_1986_Trans,” “main.YK_1987_Trans,” etc.). The aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. Though the overall study area never changed, the YKD Survey design was modified several times,...

Distance sampling (Buckland et al. 2001) is a common and well-understood method to estimate wildlife population size or density, especially for sparse and hard-to-detect populations. A main advantage of distance sampling is that it accounts for imperfect detection and gives precise estimates for a given level of effort relative to other methods. The objectives for the pilot project in 2019 was to (1) determine if distance sampling is feasible on the YKD, (2) determine what aspects of the field protocol need to be changed or...

Each year’s survey area consisted of a set of U.S. Geological Survey 1:63,360 scale quadrangle maps, where each map represented a potential sampling unit. The 1968-2005 surveys were designed to census the entire survey area, and thus all of the maps were surveyed in these years. The 2010 and 2015 surveys were stratified random samples (optimally allocated to minimize cost for a fixed variance); therefore, only a selected set of 100 maps were surveyed in these years.
