註釋Advance growth generally refers to stems of layer or seed origin, suppressed at time of logging, which are highly clumped and uneven in height and age. The possibility of integrating advance growth with other silvicultural techniques is a viable option for black spruce since seeding or planting is expensive and desired stocking levels are not always achieved. This paper presents a study that documented the abundance, distribution, and vigour of pre- and post- harvest advance growth in black spruce mixedwood and black spruce-moss sites in north-western Ontario. The study objective was to investigate attributes of advance growth by site type and its potential as a silvicultural option for resource managers in that region. Results are presented of advance growth density, stocking, and selected growth data collected from 36 black spruce stands ranging in age from 50 to 160 years.
