Sažetak
"The forest consists of forest soil fully stocked with trees, shrubs and ground vegetation, where the permanent production of wood matter and commonly useful goods are expressed in ecological (protective) and social functions of the forest" (Mati}, 1994). Today, the human population, on the local and global level, strives to realise permanently maintained development. Consequently, this requires the preservation of living standards with a tendency to continued growth, by using natural resources, with preservation of a healthy natural environment. This results in strengthening of ecological awareness on a large scale, which is assisted by media and political pressures and reflected in changes of legislative norms, interfering with the previous order and importance of primary, secondary and other products of the forest.
The volume of wood, i.e. wood mass, is the final and most important product of the forest, and the role of the forester is to determine guidelines of management in space and time, in order assist nature in the production of higher quality wood mass, while respecting the protective, aesthetic and recreational role of the forest.
Determination of the condition, monitoring the course of development and knowledge of the sequence and intensity of the influence of factors on the volume of a stand has great importance in practice, in the process of determining goals and methods of management which will enable, depending on needs and requirements, quantitative and qualitative production of the volume of wood of the investigated species in the investigated community.
Man has become a dominant factor who, by satisfying the needs of his improved standard of living, causes accelerated ecological and management changes, which considerably alter conditions of growth, development and survival of forests. In such a constellation, greater care should be paid to the volume of a stand, i.e. the course of its development through time, and the study of the regularities of interaction between factors which have an effect on the development and production of wood mass. At the same time it is important to ascertain the reactions which are caused by anthropogenic and silvicultural-management interventions, and which have an effect on changes in the stand structure and finally on the production of wood mass. Thus, in the future, by planning these mainly silvicultural-management interventions, it would be possible to achieve higher goals of sustainable management, while not disrupting ecological and sociological postulates of natural development of our forest ecosystems.
In this paper the development of volume has been studied as a function of time, in stands of Peduncled oak and Common hornbeam of different ages in the region of the Forest Administration Branch Offices of Karlovac, Zagreb, Koprivnica, Bjelovar, Našice and
Vinkovci.
