Abstract: The development of a partial cutting study established in 1957 in a mid-seral stand of western redcedar, western hemlock, western white pine, Douglas-fir, western larch and several other species, on the western side of the Arrow Lakes is reported In Research Note 78. Three treatments were tried: an improvement cut. a diameter limit cut and a salvage cut. It was the latter treatment that produced the most successful results. Accurate prediction of the premature mortality of white pine and larch influenced the selective removal of these, the larger stems in the stand. The total volume removed in the salvage cut was 169 m3/ha, which is more than double that removed In either of the other treatments. A less conservative attitude in prescribing trees to be removed would have added at least 55 m3/ha to the yield with probably beneficial effects on the subsequent development of the stand. In addition to yielding the greatest volume. the salvage cut also resulted in the greatest net volume increment of 3.9.m3/ha/an compared with 2.3 m3/ha/an for the diameter limit cut and 1.4 m3/ha/an for the improvement cut. For the same period, the net volume increment of the control was -1.0 m3/ha/an. It is suggested that the salvage cut is a highly appropriate cutting treatment for those stands where clearcutting is undesirable, such as watersheds and highway amenity belts, provided that the stand structure is appropriate for the nature of the cutting and the topographic features permit the careful logging essential for the well-being of the residual stand.
