Differing regeneration patterns after catastrophic fire and clearfelling: Implications for future stand dynamics and forest management

Abstract

Silvicultural systems in native forests typically attempt to mimic natural disturbance regimes to ensure that the dominant tree species and associated biodiversity persist. Where the disturbance regime is driven by catastrophic, stand-replacing disturbances, such as fire and windstorms, even-aged (or single-cohort) silvicultural systems such as clearfelling (clearcutting) are commonly applied. However, there are important differences between stand-replacing natural disturbances and clearfelling. Considerable attention has focused on the biological legacies that persist after these disturbances (e standing dead trees, coarse woody debris). However, the inherent variability in regeneration pat..
