The Forest Insect and Disease Survey monitored the abundance of forest pests and their damage in forested areas throughout the Island and Labrador. The extent of major pest infestations was mapped, population levels sampled and the distribution of damage surveyed to provide their status. A forecast of infestations of major defoliators is provided as well.
