Thaidene Nëné is an Indigenous protected area that spans 6.5 million acres (26,376 square kilometers) at the transition between boreal forest and tundra, including the east arm of Tu Nedhé (Great Slave Lake), the deepest freshwater lake in North America. It also provides habitat for sas cho (grizzly bears), nunı (wolves), denı́e (moose), and yutthéjëré (muskox), and the critical wintering ground of Ɂetthën (caribou).
The area was designated by the Łutsël K'é Dene First Nation in 2019 as an Indigenous Protected Area using Dene Law.
Within the Thaidene Nëné Indigenous Protected Area, Parks Canada designated an area of 14,305 km2 as a national park reserve (NPR) under the National Parks Act. The Government of the Northwest Territories established the first territorial protected area in the NWT, measuring 8,906 km2, by regulation under the Territorial Protected Areas Act. The 3,165-square kilometer wildlife conservation area (WCA) was designated by regulation under the NWT Wildlife Act.
It is the first and largest co-managed IPA in Northern Canada.
I have been working with the community of Łutsël K'é and the stakeholders of Thaidene Nëné since 2015 to document the creation and management of the IPA.
