Analysis of rare vascular plant species in need of protection in wetlands of Republic of Bashkortostan

Abstract

The work presents a systematic and phytosociological analysis of rare threatened vascular plants of the wetlands in the Republic of Bashkortostan. The work considers the plants listed in the Bern Convention list, Red Data Books of the Republic of Bashkortostan and the Russian Federation, as well as IUCN Red List of Threatened Species. In Bashkortostan, the greatest number of rare mire species is represented by the family Orchidaceae, and the second place belongs to the family Cyperaceae. The communities of low sedge-moss minerotrophic fens of the alliance Caricion davallianae and oligo-minerotrophic mires of the alliance Sphagno-Caricion canescentis are the richest in rare species. Less rich in rare species are mesotrophic paludified forests and shrublands with sedge-moss communities of the alliance Betulion pubescentis and oligotrophic shrub-sphagnum bogs of the alliance Vaccinio uliginosi-Pinion sylvestris. The communities of eutrophic mires dominated by high sedges, shrubs, trees, as well as water communities located within mire complexes have the lowest diversity of rare species.
