The Gwich'in consume traditional country foods as a main staple of their diet. Due to concerns from the Gwich'in with] regards to contaminants in the food chain, the Gwich'in Community Liaison (GCL) position was established. This position enabled the Gwich'in to be a member of and participate in research programs established by the Northern Contaminants Program (NCP). The Gwich'in Community Liaison will continue to promote dialogue and information between the Gwich'in communities, Gwich'in Organizations, NCP representatives, and NCP scientists. Gwich'in Tribal Council (GTC) GCL has participated in monthly Northwest Territories Environmental Contaminants Committee (NWTECC) meetings, liaison of relevant contaminant...

This report presents the results of a harvest survey and ethnographic research project that investigated the subsistence uses of large land mammals and furbearers in Game Management Unit 25 in the Yukon Flats region of Interior Alaska. Large land mammal species harvested and used by Yukon Flats residents include moose Alces alces, caribou Rangifer tarandus, black bear Ursus americanus, and brown bear Ursus arctos. Furbearing species included in this study are marten Martes americana, lynx Lynx canadensis, and wolf Canis lupus. For the 2008–2009 study year a total of 284 of 467 households (approximately 61%) were surveyed in the 7 Yukon Flats communities of Beaver, Birch Creek, Chalkyitsik, Circle, Fort Yukon, Stevens...

EXECUTIVE SUMMARY This study was conducted by U.S. Fish and Wildlife Service biologists during 1998 and 1999. Burbot liver was the tissue of choice for this study because chlorinated hydrocarbons, or organochlorine compounds, are lipophilic and burbot use the liver as their main somatic fat reserve (Love 1980). In addition, burbot consume high on the aquatic food chain and, therefore, are subject to the effects of biomagnification. The objectives of this study were to: determine the concentrations of organochlorine compounds in burbot livers at four sample sites in Interior Alaska; determine the significance of these data by comparing organochlorine concentrations in burbot livers with regional data for organochlorines...

This report details the monitoring activities that were conducted in upper Michie Creek during the open water season of 2007. The primary purpose of the project is to maintain access to salmon habitat in this watercourse by monitoring beaver activity and other potential barriers and breaching them when required. Research included the collection of benthic organisms and the monitoring of flow and temperature in upper Michie Creek. In addition, the relative health and abundance of both wild and enhanced juvenile chinook salmon populations that utilize upper Michie Creek were investigated. Water flow conditions in 2007 in the upper Michie Creek spawning area were more than adequate to allow spawning success...

The present-day channels of the Chena River and Noyes Slough in downtown Fairbanks, Alaska, were formed as sloughs of the Tanana River, and part of the flow of the Tanana River occupied these waterways. Flow in these channels was reduced after the completion of Moose Creek Dike in 1945, and flow in the Chena River was affected by regulation from the Chena River Lakes Flood Control Project, which was completed in 1980. In 1981, flow in the Chena River was regulated for the first time by Moose Creek Dam, located about 20 miles upstream from Fairbanks. Constructed as part of the Chena River Lakes Flood Control Project, the dam was designed to reduce maximum flows to 12,000 cubic feet per second in downtown Fairbanks....

This report summarizes the results of research conducted in 2010 on the subsistence harvest and uses of wild foods in 8 Kuskokwim River communities: Aniak, Chuathbaluk, Crooked Creek, Lower Kalskag, Red Devil, Sleetmute, Stony River, and Upper Kalskag (estimated total population 1,450). The principal questions addressed by the Donlin Creek Subsistence Research Program were how many wild foods were harvested for subsistence, the harvest amounts, and how these foods were distributed within and between communities. Related questions addressed the role of wild foods in Alaska’s economy, the role of cash in subsistence economies, the lands and waters used for subsistence practices in the central Kuskokwim area, and...
