Natural disturbance of the interior cedar/hemlock forests of BC is dominated by small-scale gap-forming processes. Partial cutting may better mimic natural disturbance regimes in these forests than clearcutting. We will study the response of seedlings to three different partial cutting treatments. The study will examine above- and below-ground growth of four conifer species (spruce, lodgepole pine, Douglas-fir, and red cedar). We will also sample seedlings for beneficial mycorrhizal fungi and disease-causing fungi. Our hypothesis is that plant vigor will be affected not only by light and nutrients available, but also by the extent of colonization by beneficial or detrimental fungi.
