Diviiion of Research 



Experimental scarification and sonnng of yellow birch. 



Forest Growth 



Measurement of hardwoods in Peninsular Ontario was continued during the 

 summer of 1950. The purpose is to provide tables that will enable woodlot owners to 

 estimate the volume of material that might be removed from their woodlots. Tables 

 for sugar maple and beech were completed during the first part of 1950. Not enough 

 data had been collected for other species until the 1950 field work was completed. 

 Work on tables for white elm and soft maple was then begun and completed early in 

 1951. Other features of tree growth and tree volume were investigated as the volume 

 table work progressed. 



Forest Soils 



Work in soils research is under the direction of Mr. G. A. Hills. 



Forest Site Rci^ions and Laudjonn Patterns: Information secured during 1950 in the 

 Kenora and Patricia areas completed a reconnaissance of the province commenced in 

 1944 with the object of preparing a site region map. This map. with a description of 

 the site regions, demonstrates the application of the recently devised site classifications 

 to Ontario conditions. These site regions will provide a better basis for the study of 

 forest regeneration, growth and yield, and silvicultural tests leading to the application 

 of improved forest management practices.
