Abstract

This report presents the findings of a research project, whose main objective was to analyze growth and yield conditions in the peatlands in Saint-Anaclet and Cabano for the purpose of establishing experimental plots to assess the effects of drainage on the growth and development of forest stands. We only selected the spruce-mosses and spruce-litter types because of the extensive areas covered by those forest types, the homogeneous structure of the stands involved, and the volume of the wood obtained from them.

This choice was based on the fact that distribution of stems in rectangular plots measuring 20 by 15 m were normal, that these are even-aged stands of 50 and 80 years, that height growth in black spruce was comparable with growth in site classes II and IV of Vézina and Linteau yield tables, and that the annuaI increment in volume was 3.4 m3/ha/year in the spruce-litter type and 1.4 m3/ha/year in the spruce-mosses type. These results were comparable to those criteria used in Finland: the annual yield of the stand should be 1.5 m3/ha/year and more if the peatland will be drained.
