Eight Dollar Mountain:
The Place, The Plants, A Growing Threat
Monday, May 4, 2026, 6:00 PM-8:00 PM
Sikiyou Field Institute
1241 Illinois River Road Selma, OR
Eight Dollar Mountain is an iconic serpentine conical mountain in the Illinois Valley, and is 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 by Kristi Mergenthaler, Botanist and Stewardship Director, 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.
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; retaining and enhancing habitat for declining bird populations; serpentine landscapes such as Eight Dollar Mountain; standing up for underappreciated species such as oak mistletoe, poison-oak, and western rattlesnakes; and connecting people to the solace and beauty of the natural world.
This presentation is free and is sponsored by Southern Oregon Land Conservancy (SOLC) and Siskiyou Chapter Native Plant Society of Oregon.
If you have any questions, please contact Paige Gerhard, Event and Volunteer Coordinator, at 541-482-3069 (Ext 107) or email [email protected].
SOLC is leading a related hike on May 9.
