Every year, since 1967, the Ministry of Forests, Wildlife and Parks (MFFP) has conducted an aerial survey of the damage caused by the main insects and diseases that attack trees. This fact sheet focuses exclusively on data concerning damage caused by jack pine budworm. The data is updated annually only if damage is observed. The aerial survey is carried out in sectors previously determined based on the damage of the previous year and the results of the inventories predicting the populations of this insect.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
