Seed Yield and Quality from Early Cone Collections in Newfoundland Populations of Black Spruce and White Spruce by Alexander John Mosseler,Canada. Forestry Canada. Newfoundland and Labrador Region,P. Tricco Pdf

Seed shortages in coniferous tree species often limit artificial forest regeneration efforts and silvicultural options such as direct seeding. Accumulated growing degree-days (GDD) were used to predict the earliest time at which cones of black spruce and white spruce could be collected without adversely affecting seed yield and quality. Cones were harvested at intervals of 100 GDD beginning about 600 GDD after pollination and ending with natural seed release in white spruce from 1200-1250 GDD.

Forest Genetic Resource Conservation and Management in Canada by Petawawa National Forestry Institute Pdf

The National Forest Genetic Resources Centre held a workshop to address issues relevant to the conservation and management of Canada's forest genetic resources. The workshop included presentations highlighting the current status of conservation efforts and ideas and strategies for optimal in-situ and ex-situ conservation of forest genetic resources. Working group discussions were a major component of the workshop and were aimed at identifying gaps in current conservation efforts, conservation priorities, research initiatives to support conservation priorities, and promoting opportunities for increased collaborative efforts. A major output of the workshop was the development of a framework for a national strategy to focus on the sound management of Canada's forest genetic resources. This report presents the workshop proceedings, including the contributed papers on forest genetic conservation.

Optimal Dates for Collection of Conifer Seed in Central Newfoundland by Curran, W. J,Hall, J. Peter,Newfoundland Forestry Centre,P. Tricco Pdf

The increased demand for seed for use in reforestation in Newfoundland has focused attention on increasing the productivity of programs of seed collection. One method is to begin harvesting cones early to reduce losses to predators. Various dates of collection were examined for black spruce, white spruce and tamarack in central Newfoundland.
