ABSTRACT: Rare fern species of Amur region are identified. These ferns have unstable positions in plant communities and need in conservation. The reasons for their rarity and limitative factors are identified. 21 fern species are rare on the Amur region territory, 10 fern species among them are known only from one location. The most endangered species are Leptolepidium kuhnii (Milde) Hsing et S.K. Wu, Protowoodsia manchuriensis (Hook.) Ching and A. tenuicaule Hayata. Most of rare ferns grow as isolated individuals, they have difficulties in spore and vegetative reproduction. Both Khingan and Zeya State Reserves are the territories of concentration of rare ferns: 8 and 6 rare ferns respectively inhabit here. Some approaches to conservation of rare species are suggested.
