DIVISION OE TIMBER :\IANAGEMENT 



During the season of 1946-47 there was still a strong demand for all knids 

 of forest products, resulting in continued activit\' in timber operations throughout 

 the Province. 



Although labor conditions were effected b>- the fact that prisoners-of-war 

 were no longer available, this condition was to some extent offset by the return 

 to bush operations of war service personnel and available civilians. As a con- 

 sequence the timber operators were able to maintain production. 



^^'eather conditions were generally favorable throughout the season enabling 

 I he operators to get their timber to the mills without delay. 



A statement of timber cut during 1945-46 season and returned in 1946 is 

 shown on Page 158, Table No. 1. 



Statements showing production b\" administrative districts of the Province 

 for the 1945-46 season are also shown on Pages 159-171, Tables No. 2 to 2L 

 inclusive. 



EoREST Resources Inventory 



A post war project of considerable importance "The Eorest Resources 

 Inventory" was organized and placed in operation earh- in the year. The method 

 adopted after a thorough stud>- of existing methods and the remarkable advances 

 in aerial photograph}- during the war involved a complete coverage of the forested 

 area of the Province b\- the most up to date aerial photograph}-. Erom this, 

 l^lanimetric base maps were to be prepared and volumetric estimates made 

 from a combined use of aerial photographs and the standard methods of ground 

 survex". 



The area to be covered consisted of 140,000 square miles. Of this area the 

 aerial j)hotography and planimetric mapping on 125,000 square miles was let 

 b\- contract to the Photographic Survey- Company, Ltd., the balance of 15,000 

 square miles to be done b>- the Aerial Sur\e> s Section of the Division of Surve>- 

 and Engineering of the Department of Lands and F^orests. 



The Aerial Photography was underwa\- b>- June 1st and continued through- 

 out the summer anrl fall season. An area of 29,777 square miles of aerial photo- 

 graph}- was completed under contract and an additional area of photographs- 

 was completed by the De})artment. 



Planimetric majjping was under\\a>- b\- November and b\- l-\'l)ruar\- delivery 

 of base maps from the contractor were started and 4,429 square miles were 

 delivered b\- the end of the \-ear. 



Type mai)ping from aerial photographs was started on recei\-ing delivery 

 of base majis. An area of 8,600 square miles i)eing completed b>- tiie end of the 

 \ear read}- for held checking and final checking of maps and completion of the 

 inventor}-. 



MANAGEMENT PLANS AND CONTROL 



In writing more ri-ct-nt puljjwood and timber concession agreements in 

 accordance with the Eorest Management Act of 1947, clauses have been incorj)- 

 orated which provide for the submission of plans for the operation and manage- 

 ment of the concession areas on a sustained \-ield basis or to maintain their 

 production capacit}-. In order to supervise the preparation of these plans, the 

 work has recentl}- been put under the direction of a forester apjjointed for that 

 purpose. It is his dut}' to prepare the outlines of the minimum requirements
