SILVICULTURE SECTION 



The responsibilities of this Section include the regeneration 

 and tending of forest crops on Crown lands and Agreement 

 Forests, and on private lands under The Woodlands 

 Improvement Act.

TREE SEED PROGRAM 



The inventory of forest tree seed in storage at the Ontario 

 Tree Seed Plant at Angus, as of June 1, 1971, was about 

 2,425,000,000 viable seeds of 51 species, weighing over 

 14^ tons and valued at approximately $450,000. A 

 conversion to the metric system of measurement for all 

 seed handling was commenced April 1 , 197 1 . 



Seed Collection. The year 1971 was a good crop year for 

 walnut and other hardwoods, but gave only a medium and 

 localized crop for the pines and spruces.

Seed Distribution. A total of 688,000,000 viable seeds 

 was supplied from storage to carry out 145 seeding projects 

 in the Province during 1971 . This seed goes into three main 

 programs: 



Nursery Stock Production 3 1 4,000,000 



Direct Seeding 327,000,000 



Tubelings 8,237,000 



Research and Miscellaneous 38,763,000 



Total Viable Seeds 688,000,000 



TREE IMPROVEMENT 



Through the application of the scientific principles of forest 

 genetics, we are improving the quality and increasing the 

 quantity of available seed. Our approach includes 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, red and jack pine, and white black and red spruce. 



During the year, we collected 4,625 scions from Plus 

 Trees; these were grafted at our co-operating nurseries. A 

 total of 1,500,000 white spruce planting stock was 

 produced from "improved" seed. From this production, 

 5,000 of the best trees were selected and planted in the 

 Gurd Township Seed Production Area. In addition, 79 acres 

 of seed production area were thinned, released or improved 

 in other ways. The planting of 2,300 grafted trees was 

 completed on 1 1 .5 acres of seed orchard. A collection of 42 

 hectolitres of cones was made from seed production areas.
