Global change and mountain forests: multi-functionality under threat?
Mountain forests cover 9 million km² of the earth’s surface and make up 23% of the global forest area. Almost 4 million km² of these forests are above 1000 m altitude. In Europe, 41% of the mountain regions are forested. In the Alps, the Carpathians and the Balkan as well as the Pyrenees, this percentage reaches more than half of the area. In many mountain regions, these forests allow for survival in harsh environmental conditions. In the last 4 decades, temperature increase in mountain regions was threefold higher than the global average. With these drastic changes, mountain forests change as well and so does the ability to fulfil their functions
