Abstract
Bukev v slovenskih gozdovih prevladuje, skupaj s smreko predstavljata kar 2/3 celotne lesne zaloge. Kot prevladujoča drevesna vrsta bo predstavljala enega ključnih dejavnikov pri izboru in načrtovanju tehnologij predelave lesa. Po žledolomu v letu 2014 je bilo v okviru sanitarne sečnje posekanega 2,34 milijona m 3 bukve. Na območjih s slabšo odprtostjo in pretežkih razmer za sečnjo ter spravilo lesa bo v gozdu še vedno ostalo 521.000 m 3 bukovega lesa. V članku je na izbranem vzorcu 10 dreves analizirana kakovost bukovega lesa - od stoječega drevesa do njegove izdelave na sortimente. Vsa drevesa so bila pred sečnjo ocenjena, nato skrojena, sortimenti pa ocenjeni po kakovosti. Pri določanju kakovostnih razredov posameznih sortimentov je bil uporabljen veljavni privzeti evropski standard za bukove hlode. Na oceno kakovosti lesa v vzorcu so odločilno vplivale predvsem slepice in napake srca. V prvem kakovostnem razredu dreves je bilo pričakovano ugotovljeno 60 % hlodovine, največ kakovosti A, iz dreves slabše kakovosti pa največ prostorninskega lesa in pa hlodovine najslabše kakovosti, predvsem razreda D. Ob obsežnih sestojnih spremembah zaradi žleda in napada podlubnikov se bo prihodnost teh sestojev gradila na bukvi

Title:Quality of beechwood in Slovenia : current situation and expected changes after the re-generation of forests following the natural disaster of glaze ice
Abstract:
Beech is a predominant tree species in Slovenian forests, and together with spruce they represent as much as two-thirds of the total growing stock. As a predominant tree species, it will be one of the key factors in the selection and planning of wood processing technologies. After the glaze ice in 2014, 2.34 million m3 of beech were felled within the scope of the salvage cut. In areas with poor openness and impossible conditions to perform felling and harvesting, 521.000 m3 of affected beechwood remain in forests. Using a selected sample of 10 trees, the article analyses the quality of beechwood - from a standing tree to its production of assortments. All trees were evaluated before the felling, then they were bucked and the resulting logs assessed in terms of quality. The European standards for beech logs were used to determine the quality classes of individual assortments. In particular, covered knots and heartwood defects had a decisive impact on the assessment of wood quality in the sample. As expected, 60% of roundwood was established in logs, the majority of the highest A-quality. The trees of poorer quality provided the most stacked wood and the logs were of the worst quality, i.e. mostly D-class. Due to changes in stand conditions caused by glaze ice and bark beetle attacks, the related stands will be restored with beech trees in the future
