Forest Insect And Disease Conditions In West Central Canada In 1994 And Predictions For 1995

This document summarizes forest pest conditions in Alberta, Saskatchewan, Manitoba, and the Northwest Territories and provides predictions of damage levels by major pests for the year. Major pests and abiotic factors affecting forests are discussed, as well as special surveys of young stands, aspen forests, and a forest nursery. Additional noteworthy insects, diseases, and tree damage agents are reported.

The Forest Insect and Disease Survey (FIDS) is responsible for conducting and reporting insect and disease surveys of forests in the Northwest Region, which includes Alberta, Saskatchewan, Manitoba and the Northwest Territories. This report summarizes forest insect and disease conditions and other tree-damaging agents within the Northwest Region for the year, and also describes pest control projects throughout the region. An update of surveys for acid rain symptoms in permanently established Acid Rain National Early Warning System plots is reported, and forecasts of spruce budworm, jack pine budworm, and forest tent caterpillar populations are given.

Wilks provides a historical background, list of publications, and description of activities for most of the major science initiatives undertaken at the federal level. He surveys a wide range of government documents and monographic and serial science collections used by both faculty and students.
