The Montane Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone in south-central British Columbia and southwestern Alberta, Canada (an ecozone is equivalent to a Level I ecoregion in the United States). A rugged and mountainous ecozone spanning 473,000 square kilometres, it still contains "two of the few significant agricultural areas of the province", the Creston Valley and the Okanagan Valley. Primarily a mountainous region, it consists of rugged ecosystems such as alpine tundra, dry sagebrush and dense conifer forests. The interior plains are encircled by a ring of mountains. The area has a mild climate throughout the year, with typically dry summers and wet winters.
The corresponding name in the United States for this ecozone, where it is classed as a Level I ecoregion by the United States Environmental Protection Agency, which is identical though differently-named than the CEC system, is the Northwestern Forested Mountains ecoregion.
This ecozone can be further subdivided into four ecoprovinces:
- Central Montane Cordillera
- Columbia Montane Cordillera
- Northern Montane Cordillera
- Southern Montane Cordillera
Seven national parks have been established in this ecozone:
- Banff National Park
- Glacier National Park
- Jasper National Park
- Kootenay National Park
- Mount Revelstoke National Park
- South Okanagan-Similkameen National Park Reserve (proposed)
- Waterton Lakes National Park
- Yoho National Park
Dozens of provincial parks have been established in this ecozone. Some of the largest and most notable ones include:
- Itcha Ilgachuz Provincial Park
- Kakwa Provincial Park
- Mount Robson Provincial Park
- Purcell Wilderness Conservancy Provincial Park
- Tweedsmuir South Provincial Park
- Wells Gray Provincial Park
