Calculating the value of standing timber (forest tax) in regular stands of sessile oak pdf HR EN  113  
Summary: In the article considers, towards the actual formula for the calculation value the forest associations: Cn = C0 * 1,0p n, methods of calculations of percentage of increments of values (p), costs foundations forest association the natural way (C0), value forest association (Cn) for regular forest association the sessileflowered oak of age 80, 85 and 105 year, ecologicalmanagement type (EGTIIE10). Associations belong to the forest community EpimedioCarpinetum betuli Ht. 1938, Illyrian forest of sessileflowered oak and usual ditch (Vukelić and Rauš, 1998). For the evaluation costs and forest fees choose model associations current cutting values (Sabadi, 1992), namely associations that has the distribution of number of trees and volumes along chest changing approximately the equal normal for certain the age, standing or ecologiceconomic type. Calculated coefficients asymmetries (b1) and fatnesses (b2) chosen model associations of sessileflowered oak has shown how real model associations near “normal” associations. On the basis of actual assortments the table for the sessileflowered oak Croatian forests by wood prices of finished products Croatian forests establish values eightyyearold associations, Cn = 97341,26 the kn / ha (346,50 the kn/ m3), eightyfiveyearold Cn = 104535,77 the kn / ha (346,32 the kn / m3) and one hundredfiveyearold 131783,14 the kn / ha (405,20 the kn / m3). Standards of costs establishment sessileflowered oak associations (C0) the natural restoration modified so what “as costs establishment” has been used legal standards separating for the biological reproduction, namely 23 % on the value marketing of forest product. Proposes the calculation of percentage increments of values (p) along the logarithm function: p = 8,870 3,692 log n, and costs being founded associations (C0) along the linear function: C0 = 2846,718 + 315,859 n. Knowing of all parameters in the formula for the determine of values of forest associations of determined age (n) and costs of exploitation of forests (En) along the unit of the wooden sentiment (the kn / m3) has been established the forest fee (the price woods on the tree stump) along Bartha’s formula: Šn = (Cn / 1,0 pn)  En. If for the calculation of the forest fees uses of normal (Bezak i et al, 1995) for EGTIIE10 and all known parameters for the calculation of forest fee along Bartha’s formula, then the forest fee for associations of sessileflowered oak determines ages (n) can calculate along the formula: Št = 214,772 + 5,481 n + 0,020 n2. For the eightyyearaged sessileflowered association has been defined that the BEP or the breakeven level of income (TP) in sixtyfiveyearaged. Key words: BEP or the breakeven level of income.; current cutting edges value associations; forest fee; model normally; percent share of wood along thickness classes; percentage increments of values; price list; standard for the biological reproduction and regeneration
