- Mountain treelines can be seen as boundaries between two vegetation zones – the alpine and subalpine zones – and function as an indicator of ecosystem change. Interpreting factors leading to changes in mountains includes disturbance from human resource use and climate as important factors. The article shows that forest line changes in eastern Jotunheimen, a mountain region in southern Norway, can be related to changes in livestock grazing pressure between the 1960s and 2002. In contrast to other European mountain regions, highly relevant climate variables such as the triterm (the summer months) have not changed in the studied region. Therefore, land-use change is considered the main driver for the forest line shifts observed in the region. However, the predicted climate warming, together with continued trends of decreasing and abandoned free-range grazing of livestock will cause further forest expansion above the present forest lines also in the eastern Jotunheimen mountain range.
