Commercial Thinning Experiments in the Horsefly Forest District

This document is a detailed report summarizing a commercial thinning experiment in the Horsefly Forest District in British Columbia. The primary goal was to assess the operational feasibility of commercial thinning as an alternative silviculture treatment, particularly focusing on developing higher-valued timber stands. The report delves into numerous technical and environmental issues, including desired crop tree characteristics, hydrological stability, and windthrow and snow-damage, backed by exhaustive production reports from the harvesting machinery and detailed snow breakage and crown growth surveys. The study concluded that commercial thinning is an operationally viable option within the Cariboo Forest Region, providing continued access to merchantable stands.
