For the future scenario with low greenhouse gas emission, the mean number of potential generations per year increased to 5.47 (range 2.43–6.57; Fig. 5b). Under this scenario, there will be no region in Germany where two or less potential generations per year occur. The potentially least affected areas with three or fewer generations are the Alpine regions of Oberallgäu and Berchtesgadener Land. The same global change model with high greenhouse gas emissions showed on average 5.75 potential generations per year (range 2.74–6.97) for Germany.
