The Bloke Plateau is one of the better odontologically studied areas in Slovenia, however, most of the data were obtained at the end of the last century. The purpose of the master's thesis was to investigate the current distribution of dragonflies in the area and to check for their possible endangerment. We conducted 29 field days in 2021, which were planned to cover different parts of the adult dragonfly flight season. Larvae and exuvias were also sampled during the surveys. The presence of dragonflies was recorded at 48 study sites, of which 27 were surveyed first time during our survey. We recorded 35 species of dragonflies. We confirmed the reproduction of 26 dragonfly species at Bloke plateau. During the survey, Green emerald damselfly (Calcholestes viridis) and Dainty bluet (Coenagrion scitulum) were recorded for the first time in the area. In total, we recorded six threatened and two protected species of dragonflies. Ornate bluet (Coenagrion ornatum) and Balkan goldenring (Cordulegaster heros) are listed in the Annexes of the Habitats Directive. The highest number of species (23) were recorded at the site Fishponds 500 m south of Godičevo. During the survey, we did not record the Common hawker (Aeshna juncea), which was a common species at the Bloke plateau in the past, but today it seems to be endangered or even locally extinct. Dragonflies on the Bloke plateau are threatened by the loss of a suitable habitat due to the drying up and overgrowing of bog habitats, as well as the development of mass tourism and excessive introduction of fish into some water bodies.
