Insects and Disease

We have identified common forest pests currently in Yukon, as well as forest pests that have the potential to become a problem in the foreseeable future. This list of forest pests was compiled as part of a project to develop educational materials that will be distributed to forest managers, and the general public. During this exercise, a total of 26 forest pests were identified, including 13 individual insects, or insect guilds that cause similar damage (e.g. budworms) and are currently in the Yukon; 9 individual forest pathogens, or guilds of pathogens that cause similar damage (e.g. blister rusts) and are currently in the Yukon; and 2 insects and 2 pathogens that currently are not in Yukon, but have potential to become forest pests.
