150 REPORT OF THE No. 7 



of the Timagami Provincial Forest but with the more definite objective of relating 

 the forest conditions and timber estimates to a preliminary forest working plan 

 for the areas. 



In addition, the 1929 survey programme included a study of the ownership 

 conditions in the Georgian Bay Provincial Forest. 



Timagami Provincial Forest Survey 



The area under examination in this survey comprises about 400,000 acres 

 and includes the townships adjacent to Timagami lake, namely, Aston (eastern 

 third) Banting, Belfast, Best, Briggs, Brigstocke, Chambers, Clement, Cole 

 (eastern half) Law (western half) Le Roche (western half) Medina, Olive (western 

 half) Scholes, Strathcona, Torrington, Vogt and Yates. 



Three parties totalling twenty-five men and under the direction of a forester 

 made up the field force. Work commenced May 28, and was discontinued 

 September 20. 



This section of the Timagami Provincial Forest may be roughly divided 

 by two distinct forest age classes. The southern half is forested by mature stands 

 with white and red pine dominating the mixtures. The northern half is an 

 immature stand reproduced following fire some sixty years previous and contains 

 a medley of associations in the mixtures of poplar, birch, white and red pine, 

 jack pine, spruce and balsam. 



Owing to the large volume of timber in the southern half more samples were 

 necessary to provide an estimate. Strip lines were run at one-quarter mile 

 intervals and the trees tallied on a width of thirty-three feet along the strip. 

 In the immature stands strips were run one-half mile apart and complete com- 

 position and age plots 100 feet long and thirty- three feet wide were taken at five 

 chain intervals. 



In this • survey a departure has been made from earlier surveys in the 

 nomenclature of forest types. Previously symbols were used on the maps to 

 designate the forest types. These proved unsatisfactory for descriptive purposes 

 and has given way to type numbers, each number referring to a summary sheet 

 containing the actual composition of the samples taken. 



For the Timagami Provincial Forest Survey township plans are in the course 

 of preparation on a scale of one inch equals one-half mile. 



Wanapitei Provincial Forest Survey 



The Wanapitei Provincial Forest is located some thirty miles north from 

 the city of Sudbury, and includes the townships of Aylmer, Norman, Parkin and 

 a portion of Rathbun. It covers approximately 70,000 acres and constitutes the 

 area covered by the fourth survey party in the field during 1929. 



The objective of this survey was a complete division of the tract into forest 

 types on the basis of the present composition and further into actual age classes. 

 Strip lines were run at one-quarter mile intervals and checked from control lines 

 established every two miles. 



The whole tract may be considered as immature, only some 1,000 acres 

 being classified as mature. The present immature stands occupy areas reproduced 

 following burns fifty-five years ago and since. 



The compilation of data, from both this survey and that conducted in the 

 Timagami Provincial Forest follows much the same method. Forest types are 

 numbered on the plans and refer to summary sheets giving a complete analysis 

 of the species of tree entering the composition together with actual ages. 



Township plans and a written report are at present being prepared.
