BALINT, Michal: Beech productivity changes due to recent climate change. [Master Thesis]. Technical university in Zvolen. Faculty of Forestry; Department of Forest Resources Planning and Informatics. Supervisor: Ing. Michal Bošeľa, PhD. Zvolen: FF TUZVO, 2020. 55 p.As a result of human activity, it is more than known that our planet will warm much more rapidly than in the last million years. This phenomenon is called climate change and its and is largely caused due to human activity. Its main causes are greenhouse gases that arise from industrial processes, ways of land use and others. These negative global impacts also causing more frequent drought periods and will show in forestry sector. These changes also affect the growing production of European Beech, which is economically and ecologically important tree species both in Slovakia and in Europe. This work deals with the influence of temperature and precipitation on growth and production in homogeneous stands of European Beech (Fagus Sylvatica L.) in Slovakia and Bulgaria in two other altitudes. On the basis of the results, it can be expected that European beech with his increment reacts positively in lower altitudes to spring precipitation and in higher altitudes for summer precipitation. In the area of Bulgaria, the impact of those factors on increment has not been confirmed, that was caused by the fact that those stands are more like primeval forest type and are on average at higher altitudes than areas in Slovakia.
