2.1. Study site
Our focal plant community was situated in a semi-natural wet meadow near the Chobotovský rybník pond in the Landscape Protected Area of Železné hory (Bohemian-Moravian Highlands, Czech Republic; 535 m a.s.l., 49°46’57”N, 15°50’17”E). We collected data on the 22 most abundant plant species flowering between the beginning of May and mid-July 2017. During the vegetation season, 51 insect-pollinated species were flowering.
