Forest Insect Damage Event

Shows areas where forest insect pests have damaged or killed trees by defoliation, foliage mining and wood boring.

Tree mortality rarely occurs as the result of one year's infestation, but from the result of several consecutive years of infestation and other contributing factors affecting weakened trees (e.g., fungal invasion).

The Government of Ontario tracks forest damage events to help proactively manage the detrimental effects to our forests.   We monitor the threat and spread of invasive forest pest insect species in Ontario.

The data is also important to the Forest Management Planning process in calculating timber volume loss within affected areas
