Figure 1. Location of sampling sites and climate history.

(A) Locations of sampling sites in Hessen, Germany. For abbreviations, see Supplementary file 1A. The sites where confirmation individuals were sampled are designated in grey. (B) Principal component analysis of monthly climate data 1950–2019. (C) Development of main growth period drought indicator from 1991 to 2019. Shown is the difference mean monthly evaporation potential in mm from April to September relative to the 1991 level. Climate and drought data obtained from https://opendata.dwd.de/climate_environment/CDC/grids_germany/monthly/.
