The biophysic and vegetation are described for six research areas in which spruce budworm population dynamics are being studied by the Canadian Forestry Service. The sites represent a wide array of conditions. One of the most meridional areas is located at the north-eastern edge of the Appalachian Mountains, in Quebec. It has a relatively mild climate, and supports a heterogeneous, healthy, balsam stand, rich in species. A structurally similar stand grows in a more continental and somewhat cooler climate near the northwestern shore of Lake Superior. A white spruce stand, growing on the northeastern shore of the lake, is also included. This stand is exposed to frequent drought stress due to a continental precipitation regime and a rapidly-drained soil. One of the research stands, an almost pure, dense population of balsam fir, is established on a imperfectly-drained site exposed to the maritime climate of southern New Brunswick. A second site was established in the same area of that province, on a site with better drainage. Another site was established in a balsam fir stand, relatively high in the Laurentian Mountains, Quebec, on a steep, northeast-facing slope, and is subject to the severe climate typical of such areas.
