Tillamook Coast Life Blog
A haven for rare plants, wildlife and grassland communities once abundant along the Oregon Coast, Cascade Head provides critical habitat for native prairie grasses, rare wildflowers and the Oregon silverspot butterfly.
The Oregon silverspot butterfly, federally listed as a threatened species, is known to only five other locations in the world. The butterfly depends on a single plant species, the early blue violet (which grows coastal grassland openings), to serve as food for its larvae. Elk, deer, coyote, snowshoe hare and the Pacific giant salamander frequent the preserve, while bald eagle, great horned owl, northern harrier, red-tail hawk and the occasional peregrine falcon soar in hunting forays over the grassy slopes.
