|Summary: The author studies the monetary value of wood assortment products in the forests of pedunculate oak (Quercus robur L.) of the humid type II -G-20. His studies follow research on the patterns of growth, production and sustainability of management with forests in the Republic of Croatia. The research showed considerable variability in the developmental course of a stand diameter structure, which, apart from site factors, it the result of different approaches and management methods in the past period. Based on past knowledge and patterns of the developmental course of a stand structure, theoretical models of a regulated forest of pedunculate oak have been made in the form of yield tables.The simulation of three models with a different number of trees and a similar developmental course of the basal area achieved a similar volume production, but different monetary value of wood assortments.|
The monetary value of wood mass production was determined on the basis of the share of wood assortments in the volume of full-size timber above 7 cm in diameter, Štefančić (1997) and the Pricelist of principal forest products for international market of "Croatian Forests" (Reg. No. DIR-01/02-1276).
The average monetary value ratio of annual production of pedunculate oak wood assortments at the end of the rotation period is 0.43 : 0.34 : 0.23 in favour of the model in which the developmental course of tree numbers is lower than the average. The total monetary value of the intermediate yield (the sum total of thinning treatments) in all three models is 1/3 of the value of the overall yield, or approximately 1/2 value of the principal yield.
During the prescribed rotation of 140 years, none of the three models displayed the current annual increment culmination of monetary value of wood assortments, nor the transversal monetary value of overall production.
The research stressed the need of complementing management plans with models containing all structural elements and guidelines so that those implementing plans may achieve management goals.
The Schumacher - Hall function proved to be the most favourable for practical application as a model for constructing assortment tables and tables of wood assortment monetary value.
Key words: monetary value of wood assortments; pedunculate oak; production; yield tables
