Harvesting Overstocked Stands of Small Diameter Trees. Report No. 5: Energy Value of Whole-Trees and Crowns.
The objective of the study was to determine the higher heating value of whole-tree chips and crown materials for species being harvested in the doghair stands on the Quilcene Ranger district, Olympic National Forest. Values, in terms of Btu's per oven dry pound, were derived for the three major species occurring in these stands: western hemlock, Douglas-fir, and western redcedar. Hogfuel derived from these stands comes from whole-tree chipping and crown materials created during the delimbing/debarking process. Since hogfuel may be created separately from these two sources it is important that their energy values are known. Separation of species is not done during whole-tree chipping, thus a composite value of hogfuel from this source was determined. 6 refs., 1 tab.
