The growth of the beech (Fagus sylvatica L.) stand on former agricultural land and its comparison with the naturally regenerated beech stand under comparable conditions

Abstract

The issue of afforestation of non-forest land (e.g. agricultural land use) is currently a significant trend in land management. Sustainable development and maintenance of its ecological stability are among the reasons. The paper compares the 30-year development of the beech stand originated from artificial regeneration on former agricultural land in the area where the Ipeľ River rises in central Slovakia. Two methods of tending were used on three long-term research plots (LTPs) established at the age of 20 years: negative crown thinning, free crown thinning and the third LTP was left to its spontaneous development. The results confirmed the positive impact of tending on the development of these stands. Compared to naturally regenerated stands under comparable site conditions, their higher quantitative production was found. Regarding the qualitative production expressed by the number of trees of selective quality, the worst results were obtained on the control plot. Based on these results, it is recommended to pay more attention to the planting stock quality used for afforestation.
