SCNPSO Program on Eight Dollar Mountain
Eight Dollar Mountain is an iconic serpentine conical mountain in the Illinois Valley and one of the most significant botanical hotspots in Southwest Oregon. Its ultramafic soils, derived from mantle rocks, support an extraordinary concentration of rare, endemic, and state- and federally listed plant species—many of which occur nowhere else on Earth, and some known only from the Illinois Valley. This otherworldly landscape long served as a living laboratory for researchers studying endemism, adaptation, and ecological resilience.
