Ecological Profile

Ecosystem Structure & Biodiversity

Spanning temperate rainforests in the Pacific Northwest, Rocky Mountain alpine ranges, and the circumpolar Boreal belt, this ecosystem supports robust populations of large carnivores, migratory waterfowl, and ancient temperate conifers.

Key Wildlife Facts:
  • ✓The Boreal forest contains 85% of Canada’s remaining pristine wilderness.
  • ✓Beaver dams create wetland habitats that reduce flood peaks, clean water, and sequester carbon.
  • ✓Pacific salmon transport millions of pounds of marine ocean nitrogen into old-growth forest canopies via bear and eagle foraging.
