Trends in forest and timberland values in the dynamic system of an even-aged forest of pedunculate oak in the management unit Josip Kozarac

In terms of multiple functions, the value of a forest varies dramatically over time and depends on a large number of influences and relationships. Some of the most important factors that influence trends in the timberland value of an even-aged forest within its economic function are the rotation period and trends in the age structure. The aim of this paper is to study the relations in forest value, forest rent and interest percentage over time as a consequence of variations in the rotation and age class area.The subjecto of the research is the forest of pedunculate oak in the first site class with a total area of 3894.29 ha. The forest contains a surplus of mature understocked stands, and the management is based on a 140-year rotation period.The value of forest land and stands has been determined using accepted methods, while trends in the entire forest and timberland value have been obtained using the SD model of even-aged forest management. The relationship of forest value trends, forest rent and interest percentage has yielded the follwing result: the value of pedunculate oak forest would increase by 5-7 monetary units (6%) if the rotation period were lengthened from 140 to 160 years.
