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 ...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. -
