Stark and toxic, diverse and rare, serpentines are a land of contrasts. Formed within the earth's mantle, serpentine rocks found their way to the surface. On serpentine soils, a unique flora evolved especially adapted to survive the severe hardships of drought, heavy metals, and nutrient stress. Complex islands of endemism and rarity developed in isolated plant communities on the severe landscapes.
The Klamath-Siskiyou Mountains of northwest California and southwest Oregon are the largest serpentine area in North America. Celebrating Wildflowers features the unique plant communities on the National Forests of the Klamath-Siskiyou Mountains. Discover sub-alpine communities, Jeffrey pine woodlands, and Darlingtonia wetlands. Learn how we are conserving these communities. Enjoy the stark beauty of the serpentines.
