Effects of terrain and geographical condition on operational efficiency in silvicultural operations were examined and subsequently the operational efficiency was standardized depending on the single operations using the data of silvicultural operations from 1978 to 2005 in University Forest in Chiba, the University of Tokyo, Japan. No significant relationship was found between terrain and geographical condition and operational efficiency except the first thinning, which would require more labor for the site at <20◦ of slope than at >20◦. Variance of each operation was increased with decreasing workload, namely number of trees or area operated. The standardized operational efficiency showed the improvement or laborsaving of silvicultural operations in the experimental forest compared to the former one.
