Abstract

Methods used in the collection of radial-growth data from host and non-host trees of the spruce budworm for the purpose of establishing evidence of past spruce budworm outbreaks are described. The preparation and examination of the material and the interpretation of the data are discussed. These techniques are based on experience gained in the course of studies in three widely-separated regions in Ontario and Quebec over a period of several years.
