Book Description
This report provides forest managers with information of pest conditions in Newfoundland, with regional information for national summaries, and forms a part of the historical record of pest conditions for Newfoundland. Insects, diseases, and conditions that were wide-spread, or that caused considerable concern are discussed in detail in the text, whereas those of lesser importance are presented in tabular form. 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.
