Natural regeneration with the shelterwood method is strongly recommended because it is flexible for configuring and adjusting canopy density to the requirements of most species. However, successful regeneration depends on the abundance and quality of the seed bank, and these variables are affected by physiological and climatic factors.
Although softwood reproductive cycles are fairly well known, there is very little specific information about species' phenological variations, seed production dynamics and factors governing seed yield in natural stands. This knowledge is important when we are considering the renewal and composition of forest stands in the context of sustainable management.
The purpose of this study was to assess seed production dynamics for regenerating the balsam fir-yellow birch stand with the shelterwood method.
