North Cascades Outstanding Biodiversity Features

  • Important habitats for wide-ranging carnivores. The North Cascades is one of the few ecoregions in Washington with a variety of large carnivores, including lynx, gray wolf, grizzly bear, and wolverine.
  • Semi-natural or natural vegetation is prevalent. The North Cascades ecoregion contains large stretches of relatively intact vegetation, including low elevation western hemlock–Douglas-fir–western red cedar forests.
  • Home to several  boreal species. These species, including several rare plants, are at the southern edge of their geographic ranges.
  • Major concentration of over-wintering bald eagles along the Skagit River. The eagles, feeding on salmon, are perhaps the largest concentration in the U.S. outside of Alaska
