Fig. 6. Example of simulated increases in treeline position from the Sarek area, northern Sweden. A. The current situation. B. After a 100-m altitudinal advance of the treeline (distribution of treeless alpine heaths: 81% of the current area). C. According to climate scenario HC (alpine heaths: 47% of the current area). D. According to scenario MPI (alpine heaths: 33% of the current area).
