However, directing forest development towards a higher wood quality and thereby its higher added value demands, to start with, measurability of the quality. Without it, the assessment of the eventual measures in the stand is almost impossible or, at least, very difficult. The currently used methodology for estimating the stem quality of standing trees on the permanent sample plots of the Slovenia Forest Service is based on the invalid sawmill standards and should be updated for general use in forestry. In this article, we briefly describe the existing methodology, present the review of the existing methodologies for estimating the stem quality of standing trees in diverse countries, and suggest a new methodology for estimating the stem quality of the trees. The basic goal of the described work was the development of the methodology with which we could objectively compare the stem quality from different stands, and which would enable assorting these trees' volumes into the potential forest wood assortments. The use of the suggested quality scale for describing the stem quality of the standing trees can represent one of the accessories for deciding where and how much time or assets should be invested in silvicultural measures in an individual standSpremljanje kakovosti lesa se začne v gozdu, saj je poznavanje trenutnega stanja eden izmed ključnih dejavnikov pri usmerjanju nadaljnjega razvoja gozda v smer večje kakovosti lesne surovine. Usmerjanje razvoja gozdov v smer večje kakovosti in s tem večje dodane vrednosti lesu pa za začetek terja merljivost kakovosti. Brez tega je presoja morebitnih ukrepov v sestoju skoraj nemogoča ali vsaj zelo otežena. Trenutno uporabljena metodologija za ocenjevanje kakovosti stoječih dreves na stalnih vzorčnih ploskvah Zavoda za gozdove Slovenije temelji na neveljavnih žagarskih standardih in bi jo bilo treba posodobiti za splošno uporabo v gozdarstvu. V prispevku je na kratko opisana obstoječa metodologija, predstavljen je pregled obstoječih metodologij ocenjevanja kakovosti stoječih dreves različnih držav in predlagana nova metodologija za ocenjevanje kakovosti dreves. Osnovni cilj opisanega dela je bil razvoj metodologije, s katero bi lahko objektivno primerjali kakovost debel med različnimi sestoji in bi omogočala sortiranje prostornine dreves v potencialne gozdnolesne sortimente (t.i. »sortimentacija«). Uporaba predlagane lestvice kakovosti za opis kakovosti stoječih dreves je lahko eden izmed pripomočkov pri odločanju kam, koliko časa ali sredstev vložiti v gozdnogojitveno ukrepanje v posameznem sestojuTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza gozdarskih društev Slovenije
