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 concerning damage caused by hemlock looper. The data is updated annually only in case damage is observed. The aerial survey is carried out in sectors previously determined according to the damage of the previous year, the results of inventories to predict the populations of this insect and the observations reported in the forest.This third party metadata element was translated using an automated translation tool (Amazon Translate).
