Artificial Regeneration , (white pine, red pine, white spruce) 



White pine, red pine and white spruce seedlings were planted In shallow 

 till over granite to compare survival and growth with a similar planting in the 

 fall of 1959. The initial tally in the fall of 1960 showed high survival of all 

 species planted in 1959. 

 Nutrient Studies . 



Studies have been conducted in the use of trace elements as a means of 

 increasing the cell sap concentration to avert frost damage of seedlings. The 

 application of one to three sprays of borax solution at three different periods 

 has been studied, and records of growth and foliage conditions of the treated 

 seedlings have been made during 1960 (white pine, red pine, white spruce, red oak, 

 white ash). During the winter, studies were made of the damage to white spruce 

 seedlings exposed to below freezing temperatures following one to three sprayings 

 of borax solution. 



WHITE PINE BLISTER RUST RECONNAISSANCE SURVEYS 



Investigation of blister rust conditions in the white pine forests of 

 the province was continued as a Departmental function, in co-operation with the 

 Districts concerned. Surveys were extended for the first time into the northern 

 limits of commercial distribution of the species, to evaluate infection and 

 damage there, and as a contribution towards the expanding planting programs. 



In the north, blister rust infection, in general, is still slight, 

 apparently for historical and geographical reasons. Farther south, a wide range 

 of forest damage is evident in different localities. 



During 1960, detailed surveys, and in some cases re- examinations, of 

 infected white pine stands were carried out in the Lake Erie, Tweed, Pembroke, 

 Lake Simcoe, Parry Sound, Sault Ste. Marie, Gogama, Chapleau, Port Arthur and 

 Fort Frances Districts. These investigations provided timely information on the
