According to statistical data, today forest services in Poland are performed by over 4,7 thousand private transactors. As a result of the complex process of privatization of the service sector in forestry, after 17 years of its implementation, private enterprises have almost entirely taken over various forest management tasks in the State Forests. The present study is an attempt at showing the influence of licensing procedures concerning the quality of forest services, performed by the Forest Entrepreneur Association, on the vocational activation of the population living in rural areas and on the job stability in this sector of services.
The paper presents the dimension of damage in fir and spruce upgrowth during light felling, carried out in predominant stand of mountain forests. The work was limited to the analysis of damage in up growth. Weak relation between the quantity of obtained wood and the dimension of damage in renovations defined to what extent the morphological build of predominant forest and trees location in the area influence the dimension of damage during cutting. Total dimension of all types up growths damage ranged from 2.6 to 12.6 in pine stand and from 1.7 to 4.7 in spruce stand.
The aim of the present research was to determine the models of the work consumption characteristics at the work-stand of the operator of the NIAB 5-15 processor aggregated with the farm tractor. Modelling consisted in approximating the mathematical functions which described the processes under analysis. The present research was conducted in pine, fir and spruce stands during early and late thinnings, where timber skidding, debranching and manipulation was performed. The research results indicate the occurrence of proportional relations between work consumption and the volume of the harvested timber, certain elements of the working day timing and the index of the quantitative intensity of harvesting which characterizes the percentage of the number of trees removed from a stand.
