Canadian Rocky Mountains Outstanding Biodiversity Features
- Mountain caribou in boreal forests. With fewer than 50 remaining in Washington and Idaho, the mountain caribou, also known as the woodland caribou, is the most endangered large mammal in the continental United States. It still finds habitat in the Selkirk Mountains.
- Montane wetlands with rare plants. At Halliday Fen in the Selkirks, more than a dozen rare plants grow, including the mingan moonwort, Buxbaum's sedge, yellow sedge, crested shield-fern, and water avens.
