“Douglas Fir Beetle in the Roaring Fork Watershed”: Current Conditions and Future Outlook
Presentations are Wednesdays at 6pm at the Third Street Center in Carbondale, CO, and Thursdays at 6pm at Hallam Lake, in Aspen, CO.
About the Presentation
Are you noticing changes in our local forest? Join Colorado State Forest Entomologist Dr. Dan West as he explores the complex factors driving the Douglas-fir beetle outbreak, from biological interactions to climate change, and dives into how Douglas-fir forest might evolve over the next 20 years. Discover the realities of the current infestation and learn about management options and limitations.
