Description

Conclusions: 'The results of this study show that black spruce and jack pine can be established successfully by broadcast seeding from the air on fresh to moist sites on a severely burned cutover area in central Newfoundland. The seeding equipment used proved satisfactory. The sowing density was estimated to be about 31,800 black spruce and 4,200 jack pine seed per acre which was entirely satisfactory under the conditions of the study. These sowing densities produced adequate stocking of black spruce and jack pine seedlings (from natural and artifical sources) on fresh to moist sites. If less natural regeneration had been present initally, a greater sowing density might have been required to produce adequate stocking of black spruce. The presence of alders was observed to have produced an increase in the shoot growth of seedlings. However, their dense canopy and rapid encroachment have caused stem etiolation and encouraged browsing damage. It is recommended that where alders appear to be spreading rapidly after fire, they should be prevented from overtopping and excessively shading softwood seedlings. The methods used successfully in this study have proved cheap in operation elsewhere in Canada and could be employed to re-seed large areas of non-regenerating burned cutovers in central Newfoundland.'
