This paper details a study conducted in the southern mountains of British Columbia to assess the survival and growth of planted Engelmann spruce and subalpine fir seedlings in different sizes of harvested forest openings. The researchers compared seedling performance across various silvicultural systems, noting that survival generally decreased with smaller opening sizes, while growth was best in larger clearcuts. The study aimed to provide insights into effective regeneration practices for high-elevation forests, considering factors like opening size, local climate, and species response.
