Tahltan Atlas: Indigenous Knowledge and Ecology of the Stikine Watershed

93,728 square kilometers of Tahltan territory, representing 11.4% of British Columbia, are documented in this atlas. The project, organized by the Tahltan Nation, maps ecological diversity across 8 biogeoclimatic zones and the headwaters of major North American rivers. It is an ongoing effort to incorporate cultural themes and community knowledge.
