The first information about algae in water bodies of the Koigorodsky National Park (southern taiga, Komi Republic)

The algal communities of water bodies of the Koygorodsky National Park, created in 2019 with the aim of preserving the unique massif of virgin forests of the southern taiga, were investigated. Algological collections were carried out in the summer of 2021 in two watercourses (the rivers Suran and Mytets – refer to the Volga river basin) and in a grass-sphagnum bog. 73 species of algae from 6 divisions were discovered: Cyanophyceae/Cyanobacteria – 18, Cryptophyta – 1, Euglenophyta – 2, Chlorophyta – 25, Ochrophyta (Xanthophyceae – 2, Chrysophyceae – 2, Bacillariophyceae – 13), Charophyta – 10 species. The basis of species diversity is formed by the periphyton communities. Complexes of dominants of different ecological groups of algae have been identified.
