This report compiles native traditional knowledge from the Northern River Basins Study area, as obtained through historical research, personal interviews with First Nations individuals, and completion of an extensive survey. After outlining the processes used to gather traditional knowledge and a historical overview of the northern river basins, the report presents community research results organised to reflect the knowledge of each community in the study area. The results are divided according to subject: health, family and community relationships, traditional knowledge, and future expectations and recommendations. Themes covered include land, water, fish and wildlife, illness and fitness, traditional skills and their transmission from one generation to another, and changes that have occurred since arrival of Europeans. The report ends with a synthesis of knowledge relating to the present spiritual, emotional, physical, social, and intellectual environment.
