Abstract:: Harvesting costs were determined for commercial thinning of young stands to achieve vegetation and wildlife objectives. This included replicated comparisons of thinning treatments. Treatments were defined based on residual tree stocking after thinning. Study procedures were developed and evaluated to improve statistical relevance. Multiple linear regression models were used to...

Creator:: Matzka, Peter J.
Abstract:: In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...
