Book Description
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.
