HEADQUARTERS 



Headquarters staff performed administrative duties and ensured co-ordination 

 between research units of the Fisheries Section and between the Section and other 

 agencies in Ontario and abroad. This function greatly increases the effective 

 amount of research applied to fisheries in Ontario beyond that amount actually 

 undertaken by the Province. Staff again participated in the programme of the 

 Great Lakes Fisheries Commission, particularly the sea lamprey control experiment. 



FORESTRY RESEARCH | 



The forest research programme is integrated between five units with head- 

 quarters at the southern Research Station, Maple, and six units located in the 

 major forest regions of the Province. The programme is described under Site 

 Research; Tree Breeding; Nursery and Plantation Research; Quality Wood Studies; 

 White Pine Blister Rust; Economics; and Silviculture Research. 



Site Research 



The three phases of site research are (i) Regional Site Research, (ii) Factorial 

 Site Research, and (iii) Land Productivity Research. The objective and scope of 

 the first two phases were introduced in the Minister's report of 1963-1964 and 

 previously. 



REGIONAL SITE RESEARCH 



The recognition, classification and mapping of land units on a'n area of 7,000 

 square miles north of Lake Superior constituted this year's programme for one 

 member of the staff. Glacial events which determined the distribution of soil 

 materials were studied, and the distribution pattern of various soil materials was 

 established. Preliminary estimate was made of timber use-capability of various land 

 classes. 



In this same region, a study of forest-site relationships on a reference area was 

 concluded and the results were reported. This study shows that the kind and depth 

 of soil material and soil moisture conditions greatly influence the composition of 

 the forest and the growth and yield of commercial tree species. 



During the fiscal year, another staff member investigated and mapped the 

 glacial landforms of an area of approximately 37,000 square miles in Sudbury and 

 Algoma Districts. 



A third staff member studied the distribution of parent soil materials in part of 

 Pembroke District in relation to geologic events, and a manuscript is being pre- 

 pared for publication. Field work is almost finalized for a similar study in Tweed 

 and Lindsay Districts. 



A report by two staff members, on the landscape units of the 1 1 counties of 

 Eastern Ontario, is nearing completion. This includes the whole of Kemptville 

 District and parts of Tweed and Pembroke Districts. It is part of the Eastern 

 Ontario Study Project carried on under the Agricultural Rehabilitation and Devel- 

 opment Act (A.R.D.A.). 



FACTORIAL SITE RESEARCH 



Two workers have continued in this field, studying soil nutrients and soil 

 moisture factors.
