The Taiga Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a rugged, mountainous terrestrial ecozone of Canada spanning most of northern Yukon and significant portions of the border between the Yukon and the Northwest Territories. This ecozone is very sparsely populated, with only a few hundred inhabitants who rely on subsistence living and the tourism industry. Most of the area's population consists of members of the Vuntut Gwitchin First Nation in the community of Old Crow, located on the Porcupine River.
