Scientists say climate change causing upward shift in the forest ecotone of Krkonoše Mountains

Czech scientists have registered an upward shift in the forest ecotone of the Krkonoše Mountains (Giant Mountains) in recent decades, which is attributed to global warming. The line where trees change to low shrubs and grassland has been moving upwards at a rate of about half a meter per year. According to Václav Treml from the Faculty of Sciences at Charles University this is one of the most visible manifestations of climate change in the country. Treml’s research team has monitored the changes in the so-called transition zone since 2017.
