Bylot Island
The Arctic Cordillera is a narrow ecozone compared to other Canadian ecozones. The majority of this ecozone borders the Northern Arctic, while the small segment within Labrador borders the Taiga Shield. However, bordering the Taiga Shield seems to affect neither itself nor the ecozones it borders because their biological properties appear to be opposites (cold climate versus warm climate; different species of plants and animals). While the Arctic Cordillera mountain system includes most of the Arctic islands and regions such as Bathurst Island, Cornwall Island, Amund Ringnes Island, Ellef Ringnes Island, Ellesmere Island, Baffin Island, Bylot Island and Labrador, the Arctic Cordillera Ecozone only covers Ellesmere Island, Baffin Island, Axel Heiberg Island, Bylot Island and Labrador.
