Abstract

The interest of researchers has now shifted from protecting individual species to communities with special conservation significance. This paper presents for the first time the results of a study of the communities of Highland Dagestan that include the East Caucasian endemic Atraphaxis daghestanica (Lovelius) Lovelius in the Tlyaratinsky District of Dagestan. Three associations were identified: Ass. Pinetum fruticoso-varioherbosum, Ass. Juniperetum spiroso-sedosum, and Ass. Astragaletum fruticoso-varioherbosum. Ass. Pinetum fruticoso-varioherbosum is described on the northwestern slopes in the vicinity of the village of Mazada, Tlyaratinsky district (1293 m ASL). Ass. Juniperetum spiroso-sedosum and Astragaletum fruticoso-varioherbosum are described on the southwestern, western, and southeastern microslopes of the spurs of the Bogossky Range (1340–1589 m ASL) near the villages Chadokolob and Antsukh. The floristic diversity of the study area is unique: it includes a relatively large percentage of endemic species, which indicates a high degree of autochthonism in the development of communities. Biomorphological analysis showed the dominance of hemicryptophytes, which constitute 50.6 % of the total number of species. The predominance of hemicryptophytes indicates the Holarctic nature of the flora. The findings obtained in the current study can be used to compile the Red List of the Republic of Dagestan, to assess the current state of rare species, and to create protected areas in the areas of growth of the studied species, in order to monitor communities including endemic species growing only in the Eastern Caucasus
