This report provides detailed information about the harvests and uses of wild resources by residents of Kaltag, Alaska during 2018. Kaltag is a rural community located in Interior Alaska along the Yukon River; Kaltag residents are primarily of Koyukon Athabascan descent. Residents participate in a seasonal round of subsistence activities that is guided by both customary and traditional patterns of use and contemporary hunting and fishing regulations. Comprehensive household surveys were used to gather community-level information about demographics, income, food security, and the harvest of over 100 resources. This report presents harvest information, including maps of the areas used for subsistence, for the following eight resource categories: salmon, nonsalmon fish, large land mammals, small land mammals, birds and eggs, marine mammals, marine invertebrates, and vegetation. Local and traditional knowledge is also incorporated into the results and was collected through recorded ethnographic interviews with select community residents and through open-ended survey comments. Survey results highlight the importance of subsistence within the community. All households (100%) in Kaltag used wild resources, and 94% harvested wild resources themselves. Overall, Kaltag residents harvested 47,907 lb of wild food in 2018, amounting to 799 lb per household and 322 lb per capita. Although a wide variety of subsistence resources were utilized, moose and salmon contributed most of the total harvest by weight. Subsistence activities generally took place within the regional vicinity of the community and were heavily focused along the Yukon River corridor and in the Kaiyuh Flats. This comprehensive baseline information can be used in the future to compare if and how subsistence harvest and use patterns change over time.
