The primary goal is to provide silviculture guidelines that allow managers to maintain commercially viable stands while enhancing the abundance of bear forage throughout the forest rotation. Key strategies involve manipulating stand density and canopy closure through techniques like cluster planting and spacing, creating light gaps sufficient for understory food plants to thrive. The implementation of these standards requires application at multiple planning levels and relies heavily on a continuous adaptive management approach for monitoring effectiveness and refining prescriptions over time. -
Disturbance Regimes in Coastal British Columbia
This paper challenges the traditional view that stand-initiating fires are the dominant disturbance regime in British Columbia's wet coastal temperate rainforests.

Through a comprehensive literature review and analysis of empirical data, the authors argue that fine-scale gap dynamics, resulting from the death of individual or small groups of trees, is the primary process shaping these forests. They present four lines of evidence supporting this, including the prevalence of old-growth forests dominating the landscape, the infrequency of historical fires, and the biophysical conditions that limit fire spread. The paper emphasizes that a better understanding of these natural disturbance patterns, particularly gap dynamics, is crucial for developing sustainable forest management and conservation strategies in British Columbia.
