MARČIŠ, Peter: Impact of global climate change on the growth of main forest tree species in Slovakia [Master thesis]. Technical university in Zvolen. Faculty of Forestry; Department of Forest Management and Geodesy. Supervisor: Ing. Michal Bošeľa, PhD. Zvolen: FF TUZVO, 2019. 66 p.Recent climate changes bring questions about the response of tree species to current changing environment. Last research show increase in productivity of many tree species, but the higher frequency of drought may have negative effect on increment. Although many papers are focused on climate change effects on tree species, the comprehensive analysis covering majority of the species distribution in Slovakia is missing.This master thesis investigates how the climate change affects the main tree species of Slovakia (European beech (Fagus sylvatica L.), including three species of oak (Quercus petraea (Matt) Liebl., Quercus robur L., Quercus cerris L.), Norway spruce (Picea abies (L.) H. Karst), Scots pine (Pinus sylvestris L.) and silver fir (Abies alba Mill.)) by quantifying the long-term growth, creating dendroclimatic models and quantifying the response of species to drought with resilience indices. We used data collected during second National Forest Inventory held during the period 2015 – 2016.Tree species react to recent changes differently, not only interspecific, but intraspecific as well, considering different altitude. The increment is mostly affected by the summer rainfall and temperatures, where also droughts play a big role. We can consider silver fir as the most perspective tree species, not only from the productivity view, but as a resilient species also. Only spruce and oaks at the altitudes lower than 800 m a.s.l. are not increasing their increment.
