Résumé

Pre- and post-harvest regeneration levels were compared for Abies balsamea-Betula papyrifera-Picea spp. forests in an area of the southern clay belt. Results revealed abundant advance softwood regeneration (mean 65 000 stems/ha), almost entirely of Abies prior to harvest. Survey following mechanical and manual whole-tree harvesting suggested a 92% reduction of softwood regeneration and a shift from softwood to a mixed or hardwood-shrub dominated regeneration. Some 90% of softwood seedlings collected after harvest were pre-established. Destruction of advance regeneration was generally greater on fine-textured soils. Hierarchic cluster analysis of ecological types revealed nine groups that could serve as a basis for operational silvicultural decision making. In general, Salix spp. and Alnus rugosa are the major competitors on poorly drained sites; Betula sp., Acer spicatum and Prunus pensylvanica dominate on thin organic deposits and coarse deposits; Populus tremuloides and A. spicatum dominate on fine-textured deposits. -from Authors
