The Ecological Experimental Station (EES) in Kremnické vrchy Mts. (Western Carpathians) was established in 1986 for purpose of long-term comprehensive study of the structure and processes of beech ecosystem. The aim of the research was to evaluate the productivity, carrying capacity and functioning of forest ecosystem. In 1989 on the EES were applied cuttng intervention of diffrent intensities (three diffrentiated shelterwood cuts and clear-cut) and one stand was left without any management treatment as a basis for comparisons. The advantages of shelterwood cut are enabling the formation of the new stand and the use of growth potency of the remaining trees. Results show that by applying various cuttng methods, some attibutes of beech ecosystem can change in the long-term (in terms of successional evolution and long lasting change), but the interventions intensity only had a short-term impact on some attibutes and with the stand gradually converging towards the same values.
