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 sessile-flowered oak of age 80, 85 and 105 year, ecological-
management type (EGT-II-E-10).
Associations belong to the forest community Epimedio-Carpinetum betuli
Ht. 1938, Illyrian forest of sessile-flowered oak and usual ditch (Vuke l i ć
and Rauš, 1998).
For the evaluation costs and forest fees choose model associations current
cutting values (S a ba d i , 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 ecologic-economic type.
Calculated coefficients asymmetries (ß1) and fatnesses (ß2) chosen model
associations of sessile-flowered oak has shown how real model associations
near “normal” associations.
On the basis of actual assortments the table for the sessile-flowered oak
Croatian forests by wood prices of finished products Croatian forests establish
values eighty-year-old associations, Cn = 97341,26 the kn / ha (346,50
kn/ m3), eighty-five-year-old Cn = 104535,77 the kn / ha (346,32 the kn / m3)
and one hundred-five-year-old 131783,14 the kn / ha (405,20 the kn / m3).
Standards of costs establishment sessile-flowered 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
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 (B ez ak i et al,
1995) for EGT-II-E-10 and all known parameters for the calculation of forest
fee along Bartha’s formula, then the forest fee for associations of sessile-flo
wered oak determines ages (n) can calculate along the formula:
Št = 214,772 + 5,481 n + 0,020 n2.
For the eighty-year-aged sessile-flowered association has been defined
that the BEP or the break-even level of income (TP) in sixty-five-year-aged.
Key words: percentage increments of values, current cutting edges
value associations, model normally, percent share of wood along thickness
classes, price list, standard for the biological reproduction and regeneration,
forest fee, BEP or the break-even level of income.
