In floristic investigations carried out in 2014–2016 in the Góra Chełm Reserve, five species of orchids were found (Cephalanthera longifolia, Platanthera bifolia, Listera ovata, Epipactis helleborine, Dactylorhiza fuchsii) and three plant communities were distinguished, documented in 20 phytosociological relevés. The number of orchids was highest in an unused quarry in a community of the class Epilobietea angustifolii: C. longifolia (786 plants), Platanthera bifolia (187), Listera ovata (16) and E. helleborine (4). In another community, riparian forest Carici remotae-Fraxinetum, one specimen of D. fuchsii was recorded. Only five C. longifolia individuals were found in the association Dentario glandulosae-Fagetum, which dominates in the reserve.
