Naturalist Nights: Forest Disturbance by Bark Beetle in Colorado with Dan West

This event was recorded on February 10, 2022 as part of the 2022 Winter Naturalist Nights Series, in partnership with Aspen Public Radio.

Dr. Dan West discusses 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.

Each winter,Wilderness Workshop, the Aspen Center for Environmental Studies (ACES), andRoaring Fork Audubon partner to co-host the popular Naturalist Nights speaker series; nature specialists from around the country were invited to talk about their studies for a special opportunity to inform the public on the nature around us, and give insight into the science that can potentially affect the way that we interact with our environment.
