providing the necessary reserves to overcome shortages caused by the natural 

 periodicity of good cone crops which may vary from every 3 to every 5 years 

 or by failure of the crop due to disease or insect attack or unfavourable climatic

Tree Improvement 



The tree improvement programme, concerned with increasing the quality and 

 quantity of seed available, was continued through the selection of additional "plus" 

 trees, the development of seed production areas and the planting of grafted trees in 

 seed orchards. The program is concerned mainly with white and red pine, white 

 and black spruce. During the current fiscal year 7,850 scions were collected 

 from "plus" trees for grafting at four co-operating nurseries. In addition, 1,000 

 scions from white pine trees showing resistance to blister rust were grafted. 76.7 

 acres of seed production area were thinned, released or otherwise improved for 

 seed production purposes. 2,193 grafted trees for seed orchards were planted 

 on 10.5 acres. 



The plans for tree improvement call for the major portion of the seed required 

 for the production of 62,500,000 trees to be obtained from seed production areas 

 and seed orchards. This will require the establishment of some 520 acres of seed 

 production area and 200 acres of seed orchard.

Nursery Soil Management 



Reforestation Section objective is to produce as economically as possible the 

 required number of top quality tree seedlings for Crown and Private planting 

 projects. (1964-65 sowing target aimed at the production of 62,500,000.) 



To assist in maintaining high quality production, approximately 500 soil and 

 500 plant samples are analysed each year. The analysis data is used as a basis 

 for making soil amendments, as an indicator of the value of new management 

 techniques, and for solving problems in stock growth. 



Trials in the use of such devices as fumigation are undertaken. For example 

 the soil fumigant Trizone was used on 12 acres of seedbed land in 1963-64 and 

 again in 1964-65 on another 12 acres. We are now determining its merit in
