Abstract: The economic loss of timber caused by over stumps and defects is an essential issue in forest science but study regarding this is very limited in Nepal. Thus, this research was objectively conducted to assess the volume of timber loss and associated monetary loss caused by over stumps and defects in logs and reason behind this. Three community forests namely Deurali, Jay Durga and Raniphanta community forests were selected for this research. Total enumeration was done so 375 stumps and 224 defected logs were measured from15 March to 15 April, 2019. The height and diameter at the butt end were measured using simple tape and D-tape respectively. Additionally, the length and diameter of defects in log was recorded. Total thirty key informant interviews and three focus group discussions were organized to assess the major causes of over stumps and defects. The timber volume loss caused by over stumps was calculated using cylindrical volume formula and volume loss caused by defect was calculated using formula, i.e. gross volume - net volume. The price of wood was collected from community forest to calculate the monetary value of timber loss. The principal component analysis was applied to assess the major causes of over stumps and defect in log. The highest total volume loss was recorded around 15.217 m3 (28.49%) caused by over stumps and out of this, it was 53.41 m3 timber loss in Deurali community forest. The loss due to defects in tree was ranged from 128.57 to 284.21 m3 in the community forests. The monetary value of loss caused by over stump was US$ 6971.14 of Shorea robusta in Deurali community forest and it was US$ 8100.52 because of defect. The principal component analysis showed that use of saw and axe for felling the trees in the community forests was considered as highest factor of over stump and diseases and over mature trees were key factors of wood defect. The research will be useful for policy makers and scientific community to monitor the timber loss.
