An assessment of advance growth destruction on mechanically logged cutovers on Fraser Companies Ltd. freehold lands
University of New Brunswick
Studies in Eastern Canada indicate that reproduction following mechanical logging in pulpwood stands may not produce future stand yields as good as the original stands. In order to study the advance growth destruction on Fraser Companies Freehold lands in New Brunswick, in each of ten stands, ten 5m squared plots were established before cutting. An additional similar set of plots were established after logging in the summer of 1977. Precut softwood advance growth densities ranged from 6,800 to 117,000 seedlings per ha and stocking levels from 80-100%. After cutting, densities ranged from 1,400 to 31,400 seedling per ha and stocking levels from 30-90%. It is concluded that additional care and precut planning of logging operations to preserve advance growth will supplement planting and prevent excessive loss of land from forest production.
