Natural disturbance data - Insect: Spruce budworm

Every year, since 1967, the Ministère des Forêts, de la Faune et des Parcs (MFFP) has been conducting an aerial survey of damage caused by the main insects and diseases that attack trees. This fact sheet focuses exclusively on data on damage caused by spruce budworm (TBE).

The aerial survey is carried out in sectors previously determined according to the damage of the previous year and the results of inventories to predict the populations of this insect.

From 2013 to 2022, the DPF acquired aerial survey videos to obtain additional observer data. Since 2023, high-resolution geotagged images have replaced videos.This third party metadata element was translated using an automated translation tool (Amazon Translate).
