In the Kamchiya protected area (BG0000116) of the Natura 2000 ecological network in Bulgaria, five types of dune natural habitats were studied in terms of the distribution of species from the Orchidaceae family. Four species from the Orchidaceae family have been identified: Anacamptis papilionacea (L.) R.M.Bateman, Pridgeon & M.W.Chase (= Orchis papilionacea L.), Anacamptis pyramidalis (L.) Rich., Himantoglossum jankae Somlyay, Kreutz. & Ovari, and Ophrys scolopax subsp. cornuta (Steven) E.G.Camus (= Ophrys cornuta Steven). For each of these species, a characteristic of the habitat, the population, as well as the accompanying plant species has been prepared, which includes various indicators: projective cover, life form, biological type, and floristic element. A correction is proposed in the distribution in Bulgaria of one of the accompanying species: Campanula sparsa Friv. Botanical literature in Bulgaria states that this species is established above 300 m a.s.l. In our research, we found it at sea level.
