Full textClimate influence on plant growth is a long-known fact. Global changes have driven research efforts forward to assess their impact on natural ecosystems, both in terms of species distribution and abundance, but also through commercial species yield studies. This study aims at determining the effect of climatic variables on the growth of black spruce and balsam fir in the Eastern Canadian boreal forest, through the use of dendrochronological data. It will then be possible to identify the main climatic modifiers involved in the growth of boreal stands, depending on their age and location. Focusing on a nonlinear least squares model including climatic and age modifiers, basal area growth modelling detected differences between balsam fir and black spruce. The results indicate that both species respond primarily to the length of the growing season and to maximum summer temperatures. Black spruce also seems to be more sensitive to drought. Models based on age and location along a north-south gradient highlighted a few differences, particularly regarding the greater response of young stands to climate, specifically to temperatures, as well as the old stands response to solar radiations. Contrary to balsam fir, the results revealed a relative independence of black spruce to the latitudinal gradient. These results are discussed in a context of climate change, particularly in regards of the productivity of both species through the lengthening of the growing season (higher yield for both species) and the increasing temperatures in conjunction with changes in the rainfall patterns (lower yield due to possible droughts for spruce).

Full textRegeneration in logging trails following irregular shelterwood cutting was assessed in Quebec’s boreal forest. In each of five sites, a regeneration inventory was carried out and study plots were installed for this evaluation. Two years after harvest, average regeneration density and stocking in logging trails were 10 780 stems•ha-1 and 77%, respectively. Regeneration density was negatively affected by increasing slash cover across all study sites. Seedling establishment was influenced by direct seeding, position within the logging trail, and substrate type. Environmental conditions were adequate: light availability was sufficient and severe soil compaction was limited. Direct seeding was not very effective on these sites, but the planted black spruce stock responded well. Results suggest that regeneration in logging trails was abundant and well distributed in the first two years after harvest.
