Köppen climate types in the Northwest Territories. The Northwest Territories extends for more than 1,300,000 km 2 (500,000 sq mi) and has a large climate variance from south to north. The southern part of the territory (most of the mainland portion) has a subarctic climate, while the islands and northern coast have a polar climate. [citation ...

Climate factors that affect trees include temperature, precipitation, sunlight, and wind. To differentiate among these factors, scientists collect information from "limiting stands." An example of a limiting stand is the upper elevation treeline: here, trees are expected to be more affected by temperature variation (which is "limited") than ...
