This report presents the assessment of the effect of drainage on the growth of black spruce (Picea mariana [Mill.] B.S.P.) and tamarack (Larix laricina [Du Roi] K. Koch) in the spruce-mosses and spruce-litter forests located at Saint-Anaclet, near Rimouski, Quebec.
In the absence of control plots, the effect of drainage was assessed from time data using the analysis of variance with repeated measurements. The time data correspond to the means of the increments (radial, apical and volume) and to the means of the form factors before and after drainage, which are determined using stem analysis. The study also includes the assessment of the ligneous production of the experimental plots, which was done by comparing inventories after 5 years.
Comparison of the inventories results in very interesting net annual increment rates for basal area and volume. On the basis of height growth, the spruce-litter forest is comparable to Vézina and Linteau's class II and Plonski's class 1. The site index of the spruce-mosses forest is comparable to Vézina and Linteau's class IV and Plonski's class 3.
