The increasing drought sensitivity of silver fir (Abies alba Mill.) is evident in the last two decades

Silver fir (Abies alba Mill.) is still counted among drought-tolerant tree species. However, its ability to cope with the recent extremely dry period has not yet been sufficiently studied. The objective of research was analyse differences in climate-growth response between silver fir, Norway spruce (Picea abies L. Karst.) and European larch (Larix decidua growing areas large-scale disintegration stands. In 2019–2021, increment cores were sampled at 16 sites along altitudinal gradient 340–775 m a.s.l. different regions Czech Republic affected by bark beetle outbreak. radial growth pattern compared that or under same site conditions. missing rings frequently recorded during peak SO2 pollution load 1966–1985, but they rarely identified years. larch, less common occurred mainly after 2015. Fir sensitive summer drought especially spruce, which showed high sensitivity regardless altitude. significant positive precipitation up 450 a.s.l., however, increased last two decades. Hence, when considering wider use it is necessary respect ecological requirements as much possible order preserve vitality production potential changing climatic
