While the Kirby project is located within the Regional Municipality of Wood Buffalo, its footprint impacts on the traditional territories of a number of Aboriginal communities both within and beyond the boundaries of the municipality. At the time of writing, interviews had been held with Heart Lake First Nation, Chipewyan Prairie Dene First Nation, and the Métis holder of trapline #2361, resident at Winefred Lake. Interviews with other Aboriginal communities were in the process of being arranged. The scope of this report was framed by one central question: What effects could existing and approved developments, the project, and planned developments have on traditional land use? Data gathered for the report came from a literature review of previous community and industry-initiated traditional land use studies, as well as interviews with Heart Lake First Nation Elders and an interview with the Métis holder of RFMA #2361. Data was then analysed qualitatively and quantitatively, with an assessment of the extent of temporary and/or permanent loss of land. The study also contains a reclamation assessment in which the potential for the re-establishment of traditional plant and animal harvesting was determined using ecosite phases and habitat suitability indices for the closure landscape of the project. The baseline study includes summary information on historical and current traditional land use of the study area. A study of existing and approved development impacts includes a quantitative analysis of existing disturbances to RFMAs by listing type of disturbance and the number of hectares that disturbance occupies. Also provided is a linkage analysis, which highlights the key concerns of interviewed trappers and Heart Lake First Nation Elders, and then determines whether the linkage (or concern) is valid or invalid based on proposed project designs and operational plans. Valid linkages are then examined qualitatively, drawing on biophysical assessments for the project. Issues and concerns identified in the literature review and interviews are summarized for each community. Finally, changes to traditional land use are considered in the context of project-specific effects and cumulative effects.
