Soil erosion and sediment transport

A regeneration study has been carried out during the summer 1976 in the lake Pipmuacan watershed on the north shore of Quebec.This study aimed to compare the effects, on the regeneration, as well preestablished as established after cutting, of two cutting methods namely with tree harvester of the Koehring type or the conventional method which is partly mechanized.From the analysis carried out in this study, one may conclude to a good regeneration, well distributed over cutting areas, of balsam fir and spruce, either with a cutting method or with the other; this regeneration is not significantly different if the number of stems of all species is considered.Nevertheless, low distribution of balsam fir and spruce following conventional cutting in the spruce balsam forest type may result in large openings in the future mature stand.Among the factors considered, those which have a significant influence on the establishment of spruce are the original forest type and exposure while establishment of balsam fir is influenced by topography and drainage and finally exposition, cutting method and original forest type influence the regeneration of white birch. Nevertheless, those factors are not the most determinant according to their low correlation coefficient.
