BARK BEETLE OUTBREAKS IN WESTERN NORTH AMERICA: CAUSES, CONTROL AND CONSEQUENCES

Utah State University Forestry Extension presents our monthly Learn at Lunch Webinar

With climate warming and more frequent and severe droughts western North America has experienced increases in disturbances arising from native bark beetle outbreaks. The focus of the talk will be on common bark beetle species and their hosts, environmental triggers for beetle outbreaks, management options for bark beetles and the ecological consequences of extensive outbreaks on forest dynamics.

Dr. Jodi Axelson’s research has primarily focused on how insect outbreaks by native bark beetles and defoliators impact forest dynamics. Jodi was educated in previously worked in British Columbia Canada, where a massive mountain pine beetle outbreak affected over 10 million hectares of the province in the 2000s. Since coming to California just over a year ago, Jodi has focused her extension activities on drought and bark beetle driven mortality across the state. Participating on the Governor’s Tree Mortality Task Force and doing extension work in the Sierra Nevada provided Dr. Axelson an opportunity to see the extensive tree mortality first hand and to identify critical knowledge gaps. In the past summer Jodi has started two research projects: one is focused on quantifying different ecosystem elements of the mortality event along a south to north transect in the Sierra Nevada, the other is using Unmanned Aerial Systems (e.g., drones) to determine if early detection of bark beetle infestations is possible. Both of these project have strong connections to land management communities and will inform decision making and management of bark beetle disturbances.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives.
