OSHR 1877 - Fern in the Granite: The Connection between Geology and Botany

  • Noncredit
View available sections

This course is offered through the Osher Lifelong Learning Institute (OLLI) at Colorado State University. You must be a member of Osher to enroll in this course.

Geology represents the physical world, and botany represents the plant world. Because landscapes of the physical world differ place to place, lifescapes upon those landscapes also differ. Plants may thrive or vanish according to attributes such as rock type, soil chemistry, elevation, slope exposure, water retention, and other geology-based factors. Such details explain both Colorado’s mosaic of vegetation types and why one Colorado fern only grows in granite and one mustard grows best in shale.

With two classroom sessions and one all-day field trip, this class will explain how geology and botany integrate to form the Colorado we recognize today.

Please Note: Tuesday, October 24th field trip is scheduled from 8:00 am - 5:00 pm and includes chartered bus transportation.

Noncredit courses do not produce academic credit nor appear on a Colorado State University academic transcript.
