The relative cheapness of regenerating spruce and pine stands in Ontario by direct seeding has encouraged foresters to consider direct seeding projects as a part of their silviculture plans. Site in terms of topography, soil moisture and vegetative competition, and weather are basic elements in assessing the feasibility of direct seeding projects. Results are directly related to the extent of seedbed preparation, and less so to the coating, encapsulating or pelleting of the seed. The manner in which the seedbed is prepared (none, plow, etc.) and the seeding method used (aerial, spot seeding, etc.) directly affects the nature of the resultant stand, the degree of stocking, and to a lesser extent tree form and the amount of thinning required. Direct seeding is a silvicultural technique that will become more popular and effective with increased experience and experimentation. It cannot replace hand or mechanical planting of nursery grown stock completely due to the unavailability of proper sites in such areas as parks, where relative precise placement and stocking oflarge seedlings is necessary.
