Abstract:The research presented in this study addressed the distribution of volume across different log grades in three hardwood species: European beech (Fagus sylvatica L.), sycamore maple (Acer pseudoplatanus L.) and English oak (Quercus robur L.). Standing trees were selected, marked, and measured. Afterwards the trees were felled and bucked into assortments according to national legislation regarding assortment grades and requirements for each assortment grade. Each individual assortment was measured and classified into one of the national log quality grades. Proportions of log volume with different grades within individual tree volumes were calculated and presented in this study. Differences were found in log grade volume distribution between different species and diameter classes. By following the national grading system for assortments, between 40% and 50% of total volume will be usable assortments in hardwoods

Title:The distribution of different log grades by volume in three hardwood species
Abstract:Prispevek predstavlja rezultate analize kakovostne strukture okroglega lesa treh najpomembnejših drevesnih vrst listavcev v Sloveniji, navadne bukve (Fagus sylvatica L.), gorskega javorja (Acer pseudoplatanus L.) ter hrasta doba (Quercus robur L.). Na različnih sečiščih po Sloveniji smo drevesa izbrali in izmerili pred posekom, nato pa po poseku izmerili dimenzije posameznih izdelanih gozdno-lesnih sortimentov ter lokacijo in velikost morebitnih nepravilnosti na ravni posameznega sortimenta. Vsak sortiment je bil razvrščen v enega izmed kakovostnih razredov A, B, C, D (hlodovina) ali drugo oblovino (nehlodovina). Nato smo za vsako posamezno drevo izračunali delež posameznega kakovostnega razreda v prostornini celotnega drevesa. V povprečju lahko pri upoštevanju zahtev trenutno veljavnega Pravilnika pri sečnji listavcev s prsnim premerom nad 30 cm pričakujemo med 40–50 % hlodovine.
