eastern Region. Forest stand maps and forest ledgers were completed for 1,941 

 square miles. These covered the Crown management units of Watabeag, Kirkland 

 Lake, Larder Lake, and also the Ontario Paper Company licence in this area. 

 Work proceeded on revision of the planimetric base maps for those areas covered 

 by the 1960 photography. 



The multiplex machine was used to interpret contours and form-lines and 

 prepare plans for the Parks Branch. Under this programme, plans were completed 

 for Butt Lake Park, at a scale of 1" = 500' with 10' contour intervals; Sand 

 Banks Provincial Park, at a scale of 1" = 600' with 10' contours; and two park- 

 sites in the Killarney area. 



The use of planimetric and forestry maps remained at a high level. The 

 photo-processing staff produced 65,369 contact prints; 4,711 photo-mosaics, at 

 a scale of 1" = 1 mile; 948 at a scale of 4" = 1 mile; and 112 at a scale of 

 2" = 1 mile; 2,194 enlargements; 278 film diapositives; 32 multiplex plates; 

 263 Kelsh plates; 2,289 copy negatives; 322 cronaflex prints, and developed 3 

 rolls of aerial film. 



Silvicultural Operations 



This encompasses the work of establishing and producing a satisfactory crop 

 on lands dedicated to forestry both in the Crown and under agreement. This 

 work is necessary as a result of logging or fires. It is also done on barren lands 

 capable of producing a good forest crop. In addition, forest is established by 

 planting on submarginal agricultural land, or land subject to erosion, which is 

 usually acquired by Municipalities and Conservation Authorities with the assis- 

 tance of the Province and then put under agreement for management by Lands 

 and Forests. 



There are two major phases to Silvicultural Operations. 



(a) Artificial Regeneration — on Crown Lands and Agreement Forests by plant- 

 ing and seeding. 



(b) Stand Improvement — on Crown Lands and Agreement Forests. 



This includes procedures to achieve natural regeneration as well as tending 

 or improving the crop by such techniques as aerial application of herbicides. 



Stand Improvement also operates special demonstration areas where known 

 silvicultural techniques are tested on an operational basis. 



Silvicultural Operations recently established a special project forester. He 

 is conducting studies on projects such as seeding and herbicide spraying with 

 helicopters. Another project is to determine the future size and location of white 

 pine growing areas. 



Artificial Regeneration 



The numbers of trees planted is less than in 1960-1961 due to lack of suffi- 

 cient stock of northern origin and a heavy call on shipping stock in the fall of 

 1960. 



1958-59 — 20,190,338 



1959-60 — 27,562,247 



1960-61 — 35,630,393 



1961-62 — 31,666,580 

 Predicted requirements for planting stock to cover future programmes indi- 

 cate a needed increase in this work. These predicted needs rise steadily to 

 43,500,000 trees in 1966-67.
