Presentation: Eight Dollar Mountain: the Place, the Plants, and a Growing Threat
Speaker: Kristi Mergenthaler
Location: In-person presentation at the Siskiyou Field Institute in Selma, Oregon at 1241 Illinois River Rd. Selma, OR 97538 

Eight Dollar Mountain is an iconic  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.Today, Eight Dollar Mountain faces increasing pressure from renewed nickel mining interests, a growing threat not only to this singular landscape but to serpentine ecosystems throughout Southwest Oregon. Mining activity poses risks to fragile plant communities, hydrology, and long-term ecological integrity. This presentation will explore the botanical significance of Eight Dollar Mountain, serpentine ecology, and the urgent conservation challenges posed by mineral extraction in one of Oregon’s most biologically irreplaceable regions. Southern Oregon Land Conservancy and Siskiyou Chapter Native Plant Society of Oregon are sponsoring this program.

Kristi Mergenthaler is the stewardship director with Southern Oregon Land Conservancy and previously worked as a rare plant botanist. Her conservation passions include rare and endemic plants; serpentine landscapes such as Eight Dollar Mt.; and standing up for underappreciated species and habitats such as oak mistletoe, poison-oak, chaparral, and western rattlesnake.
