Honoring 25 years of supporting the protection, restoration and conservation of Cascade-Siskiyou National Monument through service, advocacy and education.

The Cascade-Siskiyou National Monument is an ecological rarity. It is the only national monument set aside specifically for its biodiversity. It is home to an extraordinary array of plants and animals in a rich mosaic of forests, woodlands, grasslands, wet meadows and interior desert.

The convergence of the ancient Siskiyou and Klamath Mountains with the younger volcanic Cascade Mountains creates an intersection and connectivity corridor for these distinct ecoregions to blend.

Located in the southwest corner of Oregon and Northern California, you can find more than 300 species of birds, mammals, reptiles, and amphibians—many of them rare or endemic—that depend on the ecological integrity of the monument to survive.

On a day hike in the Cascade-Siskiyou National Monument, it is possible to experience each of the distinct ecoregions and to find plants and animals that you cannot see anywhere else in the world.

Visitors come to the 114,000-acre monument to explore, study, hike, camp, hunt and fish. You will find a biological crossroads like no other: rare, vibrant and vital.
