Vrednostne tarife za nekatere drevesne vrste v Sloveniji

Dagarin, Tadej (author), Klopčič, Matija (mentor)

Vrednostne tarife prikazujejo naraščanje vrednosti drevesa določene vrste z njegovim prsnim premerom v različnih kakovostnih razredih. Na podlagi hipotetične sortimentacije po kakovostnih razredih so bile za šest avtohtonih drevesnih vrst (jelka, smreka, rdeči bor, bukev, gorski javor, dob/graden) izdelane vrednostne tarife za izbrane tarifne razrede volumenskih tarif. Sortimentacija je bila narejena na podlagi izračunanih višin in premerov dreves in pri tem so bile upoštevane s pravilnikom predpisane dimenzije posameznih sortimentov. Vrednostne tarife so bile primerjane glede na drevesno vrsto in izbran tarifni razred. Ugotovljeno je bilo, da imata drevesna vrsta in tarifni razred volumenskih tarif velik vpliv na vrednost drevesa. Z višjim tarifnim razredom se volumen sortimentov v drevesu poveča, s tem pa se poveča tudi njegova vrednost. Drevesne vrste imajo na trgu različno ceno, zato se vrednostne tarife med vrstami lahko zelo razlikujejo. Pri povprečni kakovosti dreves listavci dosegajo višjo vrednost od iglavcev. Izmed analiziranih drevesnih vrst dosega najvišje vrednosti hrast, najnižje pa bor. Razlike v vrednosti med kakovostnimi razredi iste drevesne vrste naraščajo progresivno z naraščanjem prsnega premera in z višanjem tarifnega razreda volumenskih tarif.

• Title: Tariffs for tree value estimation for selected tree species in Slovenia

Abstract

Tariffs for tree value estimation represent curves of increasing value of a tree of a certain tree species and quality with the increase of its diameter at breast height (dbh). Based on a hypothetical assortment structure by quality classes, the tariffs were made for six native tree species (European silver fir, Norway spruce, Scots pine, European beech, sycamore maple, pedunculate/sessile oak) and applied to selected volume tariff's classes. The assortment structure of trees was determined on the basis of calculated tree heights and dbh, complying with the legal requirements for dimensions of assortments. Tariffs for tree value estimation were compared by tree species and selected volume tariff's classes. It was determined that tree species and the volume tariff's class have a significant influence on the value of a tree. The volume of assortments in a tree increases with the higher volume tariff's class, which consequently increases the value of a tree. Tariffs for tree value estimation can differ a lot between tree species, which is explained by the differences in value of timber on the market. Comparing the values of the average quality trees, broadleaves showed higher values than conifers. Our results showed that among the analyzed tree species, oak reaches the highest values while Scots pine the lowest. The differences in values among the quality classes of the same tree species increase progressively with an increase of dbh and an increase of the volume tariff's class.
