Felling, delimbing, cross-cutting and extraction of the logs were carried out. The wood obtained was used as firewood. Two different methods of logs extraction were carried out: with transporters and with polyethylene timber chutes. The working time and the labour productivity recorded during each operations are reported. The results show that in the forest utilization performed in Sicily the mean labour productivity per operator is 2.4 t of firewood per day. This value fits well the mean value recorded in Italy (2-3 t of firewood per da…
