Abstract

Background and objectives: Logging is one of the critical operations in forest management that causes damage to remaining trees in forest. Reducing frequency and intensity of damages during logging operation is one of the main goals in section cutting forests. The aim of this study was the analysis of effective factors on damage during logging of each tree in NAV FORESTS.Materials and methods: From the total of selected trees to cut in the two parcels of the NAV FORESTS, the number of 83 trees (22.7%) were randomly selected and damages to remaining trees were individual-level analyzed during felling, WINCHING and SKIDDING operation.Results: Results indicated average 13.3 damaged residual trees per each harvested tree, which 3 trees were damaged at felling stage, 8.9 trees were damaged at WINCHING stage, and 1.4 trees were damaged at SKIDDING stage. Diameter at breast height (DBH) of felled trees were from 25 to 107 with average 68.4 cm, and their heights were from 12.5 to 27.3 m with average 21 m, and damaged trees were increased by increasing of DBH and height of harvested trees. WINCHING distances were from 3 to 47 m with average 24.5 m, and WINCHING angles were 0 to 47 degree with the average 19.1 degree, and damaged trees increased by increasing the distance and angle of WINCHING. Damaged trees were increased by increasing of the number of skidd-trail curves and by decreasing of skid-trail radius. Damaged trees due to felling of trees on suitable directions, and WINCHING of the on suitable routes were lower 42.4 and 17.1 percent than unsuitable directions and routes, respectively. The DBH of wounded and destroyed trees at felling stage (63.5 and 34.6 cm, respectively) was more than their averages at WINCHING and SKIDDING stages. Average size of bole wounds was 327.1 cm2, average depth of bole wound was 20.1 mm, and average height of bole wounds from ground level was 0.86 m.The averages of the bole-wound sizes and the bole-wound height from ground level were higher at felling stage, the average bole-wound depths at the WINCHING stage were higher than other stages.Conclusion: The results reveled that appropriate management of selection cutting forests needs to develop of sciences and techniques of logging operation.Implementation of tree directional felling, and limiting of WINCHING operation to areas without standing trees, regeneration and ground slopes less than 50 percent are necessary for reducing LOGGING DAMAGES to residual trees in these forests.
