Boreal Cordillera

The Boreal Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian terrestrial ecozone occupying most of the northern third of British Columbia and southern half of the Yukon. Within it is found Kluane National Park and Reserve, and a small portion of the southern range of Nahanni National Park Reserve. Most of the area's population is based in the city of Whitehorse, and it contains most of the Yukon's population. The portion in British Columbia is barely populated.

The main economic activity is mining, particularly of gold, which discovery in the region led to the Klondike Gold Rush. In addition to the area's rich mineral deposits, active industries exist in forestry and tourism.

This mountainous ecozone is between the Montane Cordillera Ecozone to the south-east and the Taiga Cordillera Ecozone to the north. The three zones contain the Canadian Rockies. To the east are the Taiga Plains, and to the west is Alaska, though the ecozone is also adjacent to narrow strips of the Pacific Maritime. It is characterized by tall peaks and extensive plateau. The northern plateaux within the ecozone have a fairly gentle terrain, broken by numerous watercourses running through them, and are separated by wide valleys and their lowlands.
