English title: Working efficiency in timber cutting and hauling in Northern Ostrobothnia.

The aim of the study was to determine how different factors in the stand influence working efficiency in felling. In the eight cutting areas in Northern Finland was harvested a total of 745,200 cubic feet of timber. The factors recorded from the cutting areas were the number of stems per hectare, volume of the stems, quality of the logs (proportion of decayed trees and knottiness of the trees), topography of the site and efficiency of the workers in a team.

The bigger the stems were, the better the result of the workers was. When the size of the stem increased by one cubic ft., the efficiency of the work increased by 2 cubic ft. When knottiness and defects in the stem changed the class describing the quality of a tree by one class, the efficiency decreased by 4.5 cubic ft. The density of the forest affected the time used for loading the timber for hauling. The hauling distance affected the efficiency of the team, which was usually either 2 men and one horse, or 3 men and one horse. If the hauling distance was long, hauling impaired the efficiency. If the distance was short, logging impaired the efficiency of the work. The result show that efficiency of forest work is greatly influenced by the quality of the forest, the trees and the workers.
