Uz pretpostavku da će se ta slabalca osušiti, nastala je šteta od 3.817 dinara/ 0,50 ha, odnosno 7.634 din/ha. Ona stabalca koja se ne posuše i pri eventualnim proredama ne izvade — »prošvercat« će se do sječne zrelosti sastojine, a tada će se moći ustanoviti šteta koja su oni sobom donijeli. No to je predmet daljnjih istraživanja. LITERATURA Kraljić , B.: Ekonomski elementi proizvodnje socijalističkog šumarstva, Zagreb, 1952.

Assessment of Financial Losses Following The Damage by Game in Mixed Stands of Pedunculate Oak and Field Ash Summary Natural and territorial conditions for silviculture are limited, whereas, as a rule, there are no limits for the development of timber industry, provided the wood supply is insured. However, even under those conditions the timber industry needs sufficient raw material of good quality. The forest grows slowly and reacts slowly to changes. Therefore intensive and careful management since its earliest age is required. The protection from game is one of measures of intensive management of young forests. Although the game is not only an integral part of the forest but also its decoration — it causes big damages in young forests stands and agricultural fields. Nevertheless, by reasonable managing both, the forest and the game, they can continue to exist together by fencing off either the young forest or the game. By these and other investigations we have established that red and roe deer damage young forest stands, causing thus a considerable growth retardment in youth. In addition to that we have found out that trees »conceal and carry on« ineuries antil the ripenes for cutting and degrade considerably assortiments, resp. semifinal and final products of those assortments. This also leads to considerable economic losses in industrial wood processing. Forest enterprises also suffer damage which exceed by far the annual expenses for fencing off young forest stands or hunting grounds. The ash when young, is the most attractive and tasteful for game and the most »aggressive« too by nature in young forest stands of pedunculate oak and field ash. On the fenced off experimental plot (0,50 ha) we have counted 14,156 young trees after the first cleaning, 57,1% of the lot being ash. None of them was dama ged by game. On the unfenced excperimental plot (also 0,50 ha), however, we counted 13,845 young trees after the first cleaning in 1978, 6,388 of them being ash. 21,9% of that |
