Impacts à moyen terme de l'éclaircie précommerciale sur le lièvre et les passereaux nicheurs dans la sapinière à bouleau blanc de l'Est
|Abstract:||This research aims to assess the medium-term effect of the conventional precommercial thinning (PCT) and two mitigation measures on the snowshoe hare, and in complement, on nesting passerines in the balsam fir-white birch of Est. Mitigation measures that are tested are the precommercial thinning with protection of wildlife values and precommercial thinning with protection of refuge strips. Our results demonstrate that 8-9 years after PCT treatment into the study area of Lake Onatchiway, important structural differences remain between sapling stands, with and without precommercial thinning. However, it seems that, after a while, these differences in stand structure influence much less the populations of hare and nesting passerines. The key variables of habitat for the hare, i.e. the softwood cover and food availability in winter, are very similar between different treatments. Moreover, the habitats became sufficiently similar not to perceive differences in the number of species and populations of nesting birds.|
