The influence of monthly rainfall on the mean annual ring width in a 31-year-old plantation of white spruce, Picea glauca (Moench) Voss, on sandy soils near Grand'Mère, Quebec, was studied. Analysis carried out on 43 dominant trees growing without competition on a very poor dry site of coarse material indicated that current mean annual ring width is closely related to the mean monthly precipitation during June, July and August of the preceding year. Although this relationship was evident for the past 18 years, the possibility that other factors may act concurrently is recognized.
