Naturalist Nights: Forest Disturbance by Bark Beetles in Colorado
Dan West, Forest Entomologist for Colorado State Forest Service, Colorado State University
Thursday, Feb. 10, 6pm | Hallam Lake in Aspen
In this lecture, Dr. Dan West will discuss Colorado’s major bark beetle species and a recent history of beetle epidemic locations shown from an Aerial Detection Survey. Did you know that weather plays a crucial role in insect and disease activity in Colorado’s forests? As temperature and precipitation regimes change, so do the defenses in trees. Bark beetle response to tree defenses, or lack thereof, is directly related to temperature and precipitation regimes. Dr. West will discuss how trends in weather affect the health of our forests. He will also dive into bark beetle biology and tree defense mechanisms (relative to outbreak populations of beetle infestations.)
