REGENERATION IN MANITOBA

Surveys have shown that after normal logging operations in Manitoba, the regeneration of white spruce, jack pine and black spruce was not sufficient to provide future well-stocked stands. Other studies, in Manitoba and elsewhere, have determined many of the factors affecting regeneration, and of these the two important ones subject to some degree of control appeared to be seed supply and seedbed conditions. By modifying the seed supply and seedbed conditions excellent regeneration of all three species has been obtained under experimental conditions. The costs involved in these treatments were less than those normally associated with artificial regeneration. It is suggested that the recommended treatments to promote natural regeneration be introduced in current logging operations carried out on an operational scale.
