Abstract: The paper presents phytocoenologic, ecological and eco-protective research done in the northern part of Bihor Mountains, among beech forests growing on calcareous rocks with rabbit tail (Sesleria rigida). The phytocoenoses in the Seslerio rigidae – Fagetum Soó et Vida 1963 association which is described in this paper have been identified on a few rocky ridges, at altitudes between 700 – 1400 m. The 16 phytocoenologic surveys that were done in the field and are presented in the table comprise 193 species. Among these, there is a series of endemic species (Silene nutans ssp. dubia, Edraianthus graminifolius, Thymus comosus), Carpathian endemisms (Cardamine glanduligera, Primula elatior ssp. leucophylla, Symphytum cordatum, Phyteuma tetramerum), rare species (Carex brachystachys, Centaurea reichenbachii, Iris aphylla, Teucrium montanum, Veronica bachofenii, Sorbus graeca) as well as vulnerable species (Campanula rotundifolia ssp. kladniana, Dianthus kitaibelii ssp. spiculifolius, Sempervivum marmoreum) that are found on the Red List.
