A team of 2 experienced workers was time-studied and their heart rate recorded under 4 days in clearcutting of a highly self-pruned Pinus patula Schltdl. & Cham. plantation. Task work and bonus payment systems were compared, but there was no difference in production rate, only the workplace time was extended from 2.3 h/d in task work to 3.9 h/d in bonus payment. The heart rate was 115–116 P/min in felling, 105–109 P/min in debranching and 109–114 P/min in bucking. The average heart rate in timber cutting was 108–109 P/min. Work load index was 34–37%, and the workers did not show any symptoms of accumulated stress. The production rate was 3.2 m3/h, (WPT, crew), which corresponds average piecework rate, the comparable walking speed being about 6.0 km/h. There are possibilities to increase the daily task by ergonomic grounds.

Sawmilling and Carpentry, Forestry and Hunting, and Food Grains are the economic sectors compared in this study by means of the total input-output coefficient. The coefficient measures the value of direct and indirect demand in the economy caused by a demand worth one monetary unit on the sector in focus. Forestry sector has the weakest linkage to other sectors. The derived coefficients are 1.693 for Sawmilling and Carpentry, 1.183 for Food Grain and 1.167 for Forestry and Hunting.
