Vitalita a růst smrku ztepilého ve vertikálním gradientu České republiky
Kovačević, Vuk
Long periods of drought and irregular precipitation are common phenomena in the 21st century, which, along with the management of Norway spruce (Picea abies (L.) Karst.) outside its natural range in Europe, have led to the physiological decline and mortality of entire spruce stands. Drought significantly impacts tree growth and vitality, and these adverse effects are better monitored through tree water deficit (TWD) or water content in the tree. This study focuses on monitoring and analyzing the correlation between radial stem growth and climate changes at altitudes ranging from 380 to 972 meters in the Czech Republic. Growth was monitored using automatic dendrometers for five years (2016–2020). The negative impact of climate changes on radial growth is more significant at lower elevations below 650 meters above sea level, where the highest TWD occurred. This means that managing Norway spruce at lower elevations is risky and requires a change in management practices.
