FIGURE 1.

Vector maps of the areas surrounding the nine sampling sites, where the sampling of the wild bees was carried out in 2018 and 2019, located within the three sampling areas (‘K’, ‘NV’ and ‘SV’): (a) the Kormos‐valley (= ‘K’; Natura 2000 site ROSCI0091), and (b) northern Vargyas‐valley (= ‘NV’; Natura 2000 site ROSPA0027), the southern Vargyas‐valley (= ‘SV’; Natura 2000 site ROSCI0036). (c) Approximate arragement of the sampling transects for wild bees in both study years and the position of the trap nests in 2018 at the site K1. Note that the positions of the center points for the vector maps of the trap nests at all sites in both 2018 and 2019 were not at the same positions as for the wild bees.
