Abstract

An uneven-aged spruce-fir-yellow birch stand of about 13 acres on the Valcartier Forest Experiment Station has been logged on four occasions beginning in 1935. In 1938 a two-acre sample plot was established in the middle of the stand, and all per acre values presented in this report are from plot measurements in 1938, 1950, 1954 and 1959.

The stand in 1935 contained an excess of mature and overmature balsam fir. The initial objectives are: 1) to harvest this fir and to permit a satisfactory development of advance growth and the establishment of new seedlings by increasing stand light; and 2) to accomplish this without heavy mortality from wind in the residual stand, and without an increase in the volume of less valuable trees such as white birch and red maple.

These objectives have been attained by an initial heavy cut, two moderately heavy cuttings, and more recently a light cutting. The stand structure is now suitable for the adoption of a selection system of cutting, with light logging at four or five year intervals. The effects of logging on growth and regeneration have been very favourable, particularly during the five-year period 1954-1959.
