- The need to provide wood in ever increasing amounts requires that all cut-over and burned-over areas be retained in the production of wood. It also requires the rehabilitation of all other potentially productive areas which are not now growing a useful crop of trees. This can be accomplished by one or more of the regeneration methods now in use and by a programme of forest stand improvement. A continuing programme of equipment and method development should substantially assist in the attainment of the objective.Site preparation in Ontario can perhaps be said to have received it's first real impetus when some enterprising staff members rigged a granite boulder to a bulldozer to provide a crude drag type scarifying unit. This led to the construction of a number of "Rube Goldberg" devices, some of which are readily recognizable in the scarifying units currently in use.The past decade has seen the expansion of Ontario's site preparation programme from 6700 acres in 1957 to 75,000 acres in 1968. Forecast need is for 178,000 acres by 1973.Mechanical scarification currently accounts for 82% of the total treated area, with chemical and prescribed burning treatments making up the remainder.The bulk of the treated area has been for planting of nursery stock or tube seedlings. This may change appreciably because of an increasing aerial and ground seeding programme.Equipment development continues to receive top priority in order to increase efficiency and reduce costs.No "sophisticated" scarifying equipment has yet been introduced to the Ontario scene. Equipment developed by staff members continues to be the mainstay of the programme. Ontario policy is to continue its equipment development programme and to field test any other equipment which could make the site preparation programme more effective and efficient.
