"In the Jizersk\u00E9 hory Mts., the development of birch plantations was investigated on research experimental plot. The plot is located on mountain ridge at an altitude of 940 - 980 m a. s. l., and it is exposed to climatic stresses and air pollution load. European birch (Betula pendula Roth.) was planted in 1990, 1992, 1993, Carpathian birch (Betula carpatica W. et K.) in 1993. First injury symptoms of %22the new type%22 in birches appeared in 1997. From 1996 to 2001, European birch showed high mortality (29%) and health state decline (defoliation 51%). Contrary, vitality of Carpathian birch was very well (mortality 5 %, defoliation 1%). Influence of climatic stresses upon European birch impairment is obvious. Observation results confirm the importance of proper species choice, when birches are planted in the mountains."@en . .
