There are 193 algae species and intraspecies taxa belonging to 7 phyla (Bacillariophyta, Chlorophyta, Euglenophyta, Charophyta, Ochrophyta, Miozoa (Dinophyceae), Cyanobacteria), 12 classes, 30 orders, 57 families and 109 genera. 19 new for the Orenburg region’s algae flora species and varieties of algae were found (Bacillariophyta - 10 taxa ranked below the genus, Chlorophyta - 5, Charophyta - 2, Euglenophyta - 2). A significant degree of algae flora specificity of the studied water bodies has been established. According to the saprobiological analysis water bodies and streams of protected areas of the Orenburg forest-steppe Zavolzhye are characterized as I-III quality classes, from extremely clean to satisfactory cleanliness.
