A total of 90 measurements of skid trail profiles were taken on a 13.9 km long sample transect. The forest infrastructure studied was categorized into primary and secondary skid trails, trails intended for CTL harvesting and undocumented trails. The following indicators were determined on the profiles: tyre track depth, trail width, trail slope, amount of rock present, presence of roots and road category. The deepest ruts were found in Blechno-Fagetum (6.9 cm), followed by Galio rotundifolii-Abietetum (6.4 cm) and Hacquetio-Fagetum (5.6 cm), while the shallowest ruts were found in Omphalodo-Fagetum (5.3 cm). The deepest ruts were found on primary skid trails (7.0 cm), followed by secondary skid trails (5.8 cm), while the shallowest ruts were found on skid trails used by CTL technology and on undocumented trails (1.9 cm). No significant difference in track depth was found between the four individual phytosociological units, but more extensive research should be conducted in the futureZ namenom ugotavljanja vpliva fitocenološke združbe na občutljivost gozdnih tal za vožnjo gozdarske mehanizacije smo v gozdovih GE Zaplana opravili 90 meritev profilov sekundarnih gozdnih prometnic. Vzorčenje je potekalo vzdolž linije, dolge 13,9 km. Povprečna globina kolesnic na profilih je znašala 5,7 cm. Najgloblje kolesnice smo zasledili v združbi Blechno-Fagetum (6,9 cm), plitvejše v združbi Galio rotundifolii-Abietetum (6,4 cm) in v združbi Hacquetio-Fagetum (5,6 cm) ter najplitvejše v združbi Omphalodo-Fagetum (5,3 cm). Na globino kolesnic značilno vpliva kategorija prometnice, in sicer najgloblje kolesnice nastajajo na glavnih vlakah (7,0 cm), sledijo stranske gozdne vlake (5,8 cm) ter sečne poti in pobegi (1,9 cm). Rezultati kažejo, da med sestoji različnih fitocenoloških združb in občutljivosti gozdnih tal ni statistično značilnih razlik, a menimo, da je smiselno s podobnimi raziskavami nadaljevati, saj bi v preteklosti izdelane podobne fitocenološke karte lahko bile osnova za pripravo in izvedbo okolju prijazne gozdne proizvodnjeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaGozdarski inštitut Slovenije
