Abstract
V zadnjih desetletjih je aktualna problematika o klimatskih spremembah in propadanju včasih mogočnih dobovih gozdov. Da bi določili klimatski trend na rast dobov v Krakovskem gozdu in Črnem logu, smo izvedli dendrokronološko analizo. V Črnem logu smo vzorčili 20 dreves (40 vzorcev), v Krakovskem gozdu pa 9 (21 vzorcev), vendar smo hrastove kronologije dopolnili z že obstoječimi kronologijami in tako skupno pridobili 61 vzorcev. V dendrokronološkem laboratoriju smo jih primerno obdelali, nato analizirali s pomočjo programa ATRICS in še ostalih računalniških programov. Ugotovili smo, da obstajajo razlike med hrasti iz Krakovskega gozda in Črnega loga, obenem pa ugotovili klimatski vpliv na rast za oba kompleksa, ki se kaže kot negativni vpliv nadpovprečnih temperatur in podpovprečnih padavin. Značilna leta so izrazitejša v zadnjih treh desetletjih, kar nakazuje na pogostejše klimatske ekstreme in je znak za hitro spreminjajoče se podnebje.

Title:The impact of environmental factors on the growth of pedinculate oak (Quercurs robur L.) in the basins of Mura and Krka river
Abstract:
In recent decades, the issue of climate change and the decline of once mighty English oak forests has become topical. In order to determine the climatic trend on the growth of pedunculate oak in Krakovski gozd and Črni Log, we performed a dendrochronological analysis. In Črni log we sampled 20 trees (40 samples), and in Krakovski gozd 9 trees (21 samples), supplementing the oak chronologies with already existing chronologies. In total, 61 samples were obtained. They were properly processed in the dendrochronological laboratory and then analyzed using the ATRICS program and other computer programs. We found that there are differences between the oaks from Krakovski gozd and Črni log, and at the same time found for both complexes a climatic impact on growth, manifested as a negative influence of above-average temperatures and below-average precipitation. Pointer years are more pronounced in the last three decades, indicating more frequent climate extremes, and a rapidly changing climate.
