- Description:
- Weight sampling has been used as an efficient measurement method to estimate log scale volume and assess mill inventory. In this thesis, I review past North American weight scaling research and identify areas for subsequent scientific investigation. In chapter three, I describe a field study designed to model sawlog moisture loss in Douglas-fir sawlogs on the University of Idaho Experimental Forest. Of variables considered, days since harvest, sawlog size, and vapor pressure deficit were the best predictors of stem moisture content. These results supported my hypothesis that sawlog moisture content affect weight scaled volume and value estimates. In the fourth chapter, net truckload weight, log small-end diameter, length, piece count, percent defect, and seasonal quarter were identified as significant influences on weight and volume relationships statewide. Species-level linear mixedeffects models were developed to predict net sawlog volume per truck based on a stratified random sample of 7929 loaded trucks sampled across Idaho.
