    Four Major Insect Pests of Forests in Canada

    Many insects are considered pests to Canada’s forests, meaning they cause significant ecological or economic damage to forest ecosystems. These species can injure trees in various ways, including boring through wood, eating leaves, and introducing pathogens to trees. These stressors can cause economic damage by reducing the amount of wood fibre that can be harvested and can sometimes negatively impact the ecosystem. While some of these pests have been recently introduced to Canadian forests from other parts of the globe, the majority of insect forest pests in Canada are native species. Under ordinary conditions, these species are natural sources of disturbance and diversity that can help to maintain healthy forests over long periods. However, human-mediated factors such as climate change, the introduction of non-native species, and biodiversity loss have more recently worsened the impacts that certain species can have on Canadian forests. Below is a list of just a few of the many such insects impacting Canadian forests, along with the estimated area of forest, in hectares, that a population outbreak defoliated or killed as well as the year that outbreak occurred.
