Abstract
The quantity and quality of the harvesting residues in a balsa plantation located in East New Britain Province of Papua New Guinea has been evaluated in this paper. The plantation was harvested manually with chainsaw and man-power to extract the industrial wood at age six years. A standard harvesting residue assessment method was applied using line transects. The total weight of the remaining harvest residues on the site after wood extraction was 211.7 tGREEN ha-1 and the major component was un-merchantable stem wood (121.3 tGREEN ha-1; 57.3%). Bark was the next major component of the residue (59.3 tGREEN ha-1; 28.0%). The average moisture content of the wood components recovered over the two days was determined. The average moisture content in harvesting first day was 50% while the average for the day following harvest operation was about 48%. The elemental content of the harvest residues was estimated based on published data for eucalypts in the absence of data for balsa and it showed that calcium was the largest component while phosphorous was the lowest elemental component of the harvest residues. The results indicate that the level of remaining harvest residues in this study area was relatively higher than other reported studies which reflects the combination of the log specification applied and the nature of the stem defects in balsa trees. The level of residues indicated the possibility of additional woody recovery for bioenergy.
