Ts’udé Nilįné Tuyeta

What is Ts’udé Nilįné Tuyeta?

Ts’udé Nilįné Tuyeta (Tsoo-den-ee-len Too-yuh-ta) is a Indigenous and territorial protected area.

Established under the Protected Areas Act, Ts’udé Nilįné Tuyeta will strive to protect the biodiversity of the Taiga Plains and Taiga Cordillera while contributing to the cultural continuity of an area that is a sacred place and harvesting area of the K’asho Got’ı̨nę.

Ts’udé Nilįné Tuyeta is 10,060 km² in size and lies west of the Mackenzie River and the community of Fort Good Hope.

The establishment of Ts’udé Nilįné Tuyeta helps the GNWT fulfill commitments to the protection of biodiversity under the Pathway to Canada Target 1 initiative and the GNWT’s Healthy Land, Healthy People Action Plan, contributes to mitigation efforts under the 2030 NWT Climate Change Strategic Framework and, more broadly, supports the GNWT’s commitment to working with Indigenous governments to advance their priorities.
