An economic evaluation of a number of silvicultural treatments, which include spacing, respacing and thinning in Sitka spruce and coastal lodgepole pine is presented. The results show, for the two prices assumed, that lower crop densities than those now practised lead to greater profitability if wood quality is not drastically reduced. The need for a detailed examination of the relationship between silvicultural treatment and wood quality is advocated. The evidence indicates that while lower than current crop densities lead to greater profitability, the optimum will depend upon the results from the suggested wood quality study.
