The Role of Insects and Diseases in Aspen Biology
USU Forestry Extension presents this Learn at Lunch Webinar:In part due to its vegetative strategy, western aspen is host to a large number of insects and diseases. However, only a few are agents of significant impact that can cause or warn of substantial changes in the condition of aspen clones. Environmental conditions, particularly drought stress, also play an integral role in the life cycle of the important insects and diseases of aspen, and regional droughts were the triggering factor in the initiation of the most notable instances of substantial aspen dieback and decline.
