City Removing and Replacing Infected Ash Trees

North Bay, ON – August 6, 2019 – The City of North Bay will begin removing ash trees infested with the emerald ash borer from parks and municipally-owned properties this summer.


First detected in Ontario in 2002, the Emerald ash borer is an invasive insect from Asia that feeds on all species of ash tree. There is no known method to eradicate the wood-boring insect.


Work is now underway to identify and inventory infected trees throughout areas of the city. Typically, the borer has been present for at least two years before signs of infection are visible. A number of infected ash trees have been identified in Lee Park. They will be removed starting Wednesday in order to prevent unsafe conditions as part of the installation of new playground equipment.


Trees that are removed due to infection will be replaced on a one-to-one basis with a variety of species in order to minimize any future invasive species-related risks.


For assistance with trees on private property that have been affected, owners may want to contact a qualified arborist who is familiar with this type of infestation. For more information on the Emerald Ash Borer, visit the Canadian Food Inspection Agency website.
