This research took the form of a survey conducted among forestry experts to examine the acceptability of the criteria proposed by Poje et al. (2019) on the basis of previous studies. The survey was conducted on the 35th Forestry Study Days Conference and involved 62 respondents from different institutions. The results of the survey showed that the harmonised criteria are stricter than the proposed criteria and that the assessments by individual indicators within the criteria vary between stakeholders. According to the proposed harmonised criteria, a density of 192 m/ha with skid trails and an additional 193 m/ha with harvester trails is allowed. The maximum rut depth in skid and harvester trails shall not exceed 30 cm and 20 cm, respectively. The maximum rut depth on 90% of the length of all harvester trails at the logging location shall not exceed 10 cm. Based on the results of other studies, the proposal for harmonised criteria also appears to be reasonable and appropriate from a technological, economic and environmental point of view. Before the harmonised criteria are introduced in practice, a method for assessing soil damage needs to be developed, in addition to on-site verification of the respective criteria and their possible reorientationSplošno veljavna, predvsem pa v stroki sprejeta merila sprejemljive poškodovanosti tal po gozdni proizvodnji so predpogoj za učinkovito varovanje gozdnih tal in objektiven nadzor nad kakovostjo izvedbe gozdnih del. V raziskavi znotraj gozdarske stroke smo preverili sprejemljivost meril, ki so jih na osnovi dosedanjih raziskav predlagali Poje in sodelavci (2019). Anketiranje je bilo opravljeno na 35. Gozdarskih študijskih dnevih, kjer je na anketo odgovorilo 62 udeležencev iz različnih ustanov. Rezultati ankete so pokazali, da so usklajena merila strožja od predlaganih ter da se ocene po posameznih kazalnikih znotraj meril razlikujejo med deležniki. Po predlogu usklajenih meril je dopustna odprtost z vlakami 192 m/ha, s sečnimi potmi pa dodatnih 193 m/ha. Največja globina kolesnic na vlakah ne sme presegati 30 cm, na sečnih poteh pa 20 cm. Največja globina kolesnic na 90 % dolžine vseh sečnih poti na delovišču naj ne presega 10 cm. Tudi na osnovi rezultatov drugih študij se zdi predlog usklajenih meril smiseln in primeren s tehnološkega, ekonomskega in ekološkega vidika. Pred uvajanjem usklajenih meril v prakso je poleg njihovega preverjanja na terenu in morebitnega ponovnega usklajevanja treba nujno razviti metodo za ocenjevanje poškodovanostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaGozdarski inštitut Slovenije
