What makes the Siskiyou Crest region so significant?
As a transverse range (the only mountain range running primarily east to west in the Pacific Northwest), the Siskiyou Crest acts as a land bridge connecting major mountain ranges and ecosystems, with influences from six biotic regions: Cascade Mountains, Coast Range, Willamette Valley, Great Basin, Central Valley, and Sierra Nevada. By bringing together these diverse ecosystems, a mosaic of habitats blend together, creating a rich tapestry of environments, unique plant communities, and a multitude of rare and endemic species found nowhere else on earth. We invite you to explore this little-known but important region.
