The Yukon North Slope (YNS) is a vast coastal plain that supports several species of arctic wildlife, including migratory birds, polar bear, grizzly bear, caribou, muskoxen, Dall’s sheep and moose. Since the signing of the Inuvialuit Final Agreement, in 1984, the YNS was managed as “a special conservation management regime whose dominant purpose is the conservation of wildlife, habitat and traditional native use.” In 2014, Round River began supporting the North Slope Wildlife Management Advisory Council in developing an updated YNS Wildlife Conservation and Management Plan for the area. We conducted extensive community workshops and interviews in the Inuvialuit community of Aklavik, working with land-users to characterize the habitat of the YNS and the wildlife it supports. This information was used to develop a series of technical models and reports on Inuvialuit Traditional Knowledge of Wildlife Habitat and Use. Additionally, all data collected and produced was represented spatially within a digital atlas that serves as the foundation for guiding continued stewardship of the YNS and the traditional land use of the Inuvialuit. These combined efforts helped lead to the signing in 2024 of the Aullaviat/Anguniarvik Traditional Conservation Area Agreement, placing the area under formal protection with Indigenous-led management.
