Although dominance was well expressed by tree individuals and there was no evidence of stagnation, such stands would doubtless benefit from early thinning. More de- tailed observation will be needed to locate them for treatment. SPECIES COMPOSITION Hemlock has been the dominant species in the regenerating stand since logging, both in numbers and size. However, a trend toward more spruce at the expense of hemlock is evi- dent (fig. 12). The higher percentage of hem- lock soon after logging reflects the prevalence of advanced hemlock seedlings in the stand. As many of these died, more spruce became established from natural seedfall after logging. The percentage of cedar remained nearly con- stant. 11.
