Abstract

British Columbia forest practices are by law based on sustainable forest management. The goal is to integrate ecosystem processes with management practices. The dominant proposal to promote healthy ecosystems is to use forest practices that emulate the natural disturbance regimes. Yet there is a lack of knowledge regarding the natural disturbance processes and resultant stand structure in many of these forest ecosystems. The result is a situation where managers have few or inadequate tools to accomplish sustainable forest management. The proposed research will adapt and apply recent methods developed in disturbance ecology, combined with established methods to examine fire-return intervals, to compare the frequency and impact of biotic versus abiotic disturbance agents along an ecological gradient of sub-boreal, dry warm to wet cold ecosystems. The research will quantify the disturbance regimes in these ecosystems. It will provide guidelines for alternative silviculture systems that are meant to emulate natural disturbance processes.
