Аннотация: The renewability of the forest is an important factor affecting our long-term economy, as it provides the basis for the sustained or continious yield of forest products from land best suited to this crop. Success in forest management depends primarily on the establishmentn of adequate regeneration of disirable species as soon as possible after the mature forest is cut. Tis therefore important in preparing to implement a sustained-yield management policy to know how well this requirement is being met under present operating conditions, and it was with the oject of having a comprehensive statement on the situation in Ontario that the Research Council of Ontario requested Prof. Hosie to review and report on the regeneration surveys that had been undertaken by various government and industrial agebsies in this Province.
