Abstract

The algal flora of 7 water bodies of Orenburg forest-steppe Trans Volga region protected areas was studied. 193 species and intraspecific taxa of algae belonging to 7 phyla, 12 classes, 30 orders, 57 families and 109 genera were identified. According to the results of a saprobiological analysis studied water bodies and streams are characterized as xeno-, oligo-, and β-mesosaprobic, grades 1-3 of quality, from extremely pure to satisfactory purity. In some water bodies (pond on the Zhmakovsky creek – natural monument «Kuzminka creek with tributaries^ and pond of the natural monument «Aksakov’s park»), disturbances in the stability of ecosystems and various stages of eutrophication were recorded. The data obtained indicate the need for strict compliance with the restrictions already provided for these natural monuments and the use of more effective protection measures to restore ecosystems and improve water quality within the studied objects.

The structural and functional characteristics of algal flora allow conclusions to be drawn on the state and functioning of aquatic ecosystems, water productivity, water quality
The subject of this study was qualitative and quantitative water samples taken from water bodies and watercourses located on the territory of 6 natural monuments of regional significance during the summer of 2018
