East Gwillimbury Eatperimental Project 



The Bast Gwlllimbiipy Experimental Project was started in the fall of 

 19^9 • The main objectives are the study of the growth rate for tree spacings 

 of six, nine, and 12-foot intervals, the effectiveness of annual pruning of 

 conifers and deciduous trees, the study of compat ability and regeneration of 

 our common species, and the establishment of a plantation in an easily accessible 

 area containing the majority of species. 



Replacements have been carried out as necessary in the spacing experi- 

 ment o Approximately 20 acres of the main plantation were planted in 1952 and 

 20 acres in 1953» Annual pruning was commenced in 195^» 



REGIONAL RESEARCH FORESTERS 



MID-TSBSTBRN REGION 



Research conducted during the past year was once again divided into 

 the two fields of silviculture and research co-ordination. 



Silvicultural Research 



This portion of the research activities was confined to projects 

 dealing with regeneration problems of the conmiercially important tree species* 

 Studies in the three fields: cutting methods to promote regeneration; tree plantini 

 and artificial seeding, were either initiated or continued* 



Cutting Methods Research 



The work in this field is of necessity of a long term nature and con- 

 sists of the establishment of peimanent study areas where variations in the 

 normal cutting methods can be introduced and their effects studied. 



In 195^-55 the work was continued as follows: 



(a) The variations and controls established in the Auden area in 19^ and 

 1952 were re-examined. 



(b) The final scarification portion of the variation established in the 



Dog River area was completed. The permanent sample plots were also re-established 

 and examined.
