Alaska Subsistence Harvest of Birds and Eggs, 2013, Alaska Migratory Bird Co-Management Council.

摘要

This report presents subsistence harvest estimates of birds and their eggs in Alaska for the data year 2013. Data were collected through the harvest assessment program of the Alaska Migratory Bird Co-Management Council. This program relies on collaboration among the U.S. Fish and Wildlife Service, the Alaska Department of Fish and Game, and a number of regional Alaska Native organizations. Information obtained by this program is used to evaluate federal subsistence harvest regulations, to document customary and traditional uses of migratory birds in Alaska, and to plan for the continued harvest and conservation of birds. Participation of communities and individual households in the harvest survey is voluntary. The survey covers spring, summer, and fall harvests in most regions. Some regions also have a winter survey. Harvest estimates are based on a stratified multistage clustered sample of communities and households. The sampling frame encompasses all households in regions eligible for the subsistence harvest of migratory birds and their eggs in Alaska. Households are the basic sampling unit. Data at the household level are confidential and data at the community level are considered sensitive. Communities with similar harvest patterns are grouped in subregions. Harvests reported by surveyed communities are expanded to nonsurveyed communities in the same subregion. Subregions are grouped into regions, which correspond to the designated migratory bird management regions. Within communities, households are stratified by harvest level. Communities and regions are surveyed on a rotating schedule, which is adjusted annually according to monitoring priorities and funding availability. In 2013, the harvest survey was conducted in only 1 region, the Yukon-Kuskokwim Delta.
