This document investigates the long-term effects of pre-commercial stand thinning in lodgepole pine forests in British Columbia, specifically examining 30-year responses across a range of thinning densities. The central focus is on whether heavy thinning can simultaneously enhance forest productivity, measured by merchantable wood volume and carbon storage, and accelerate the development of old-forest structural attributes important for wildlife conservation. Findings revealed that heavy thinning did create large dominant trees with substantial crowns and other old-growth features, partially supporting the goal of restoration of old-forest structural attributes, and restored much of the lost carbon storage through crown growth. This study suggests that the structural complexity created by heavy thinning, rather than forest age alone, may be sufficient to sustain comparable total abundance, species richness, and diversity of forest-floor small mammals to that found in old-growth stands, highlighting a viable silvicultural approach to address timber needs and ecological restoration.
