In this research volume and weight of logging residue were estimated in two compartments with different ground slopes (upper and lower than 50%) in Hyrcanian forest of Iran. The results showed that the means of volume, weight and number of logging residual was significantly higher in the slopes of > 50% than slopes of < 50% (P < 0.05). The mean of logging residual volume in the slopes of < 50% and > 50% were 3.56 ± 0.38 and 4.62 ± 0.45 m3.ha-1. The mean of pieces volume, weight, length and diameter in slopes of > 50% was significantly higher than slopes of < 50%. The ratio of residue volume to logging volume in the slopes of > 50% were estimated 21.2%, while in the slopes of < 50% were estimated 17.1%. In the northern forests of Iran each logging planning should be assessed regarding feasibility residue collection and transportation. Utilization of logging residue requires careful planning.
