Abstract
Interest in production of sawlogs from eucalypt plantations in Australia has increased as logging in native forests has declined. Management for sawlog production commonly involves early-age selection and pruning of potential sawlog trees, and thinning. Existing stand-level models developed using data from unthinned plantations, grown primarily for pulpwood, cannot provide accurate estimates of sawlog yield for thinned plantations, and further model development is required. We addressed this issue using an individual-tree distance-independent modelling approach. Data from thinning and pruning experiments at three sites in northern Victoria were analysed, and diameter increment models were es..
