Monitoring of aquatic communities of higher plants in the waters of protected areas under the jurisdiction of the federal state budgetary institution "Zapovednoe Podlemorye"

Vegetation is one of the most important components of aquatic ecosystems. Its condition may indicate the degree of purity of the reservoir and the stability of the aquatic ecosystem as a whole. The article is aimed at studying vegetation as one of the key elements of aquatic ecosystems. Within the framework of the study, we have explored Fertik, Ongokon, Zmeyevaya bays, the area of Сape Monakhovo and inflow into Lake Arangatui. When studying the vegetation cover of water bodies, we have used the method of ecological profiles. In each bay, 1 profile was laid from the water's edge to the maximum depth of hydrophyte growth (6 m). The work on the profile involves recording the species composition, measuring the length of dominant plant species, and registration of the depth and nature of soil. We have measured the water transparency using a Secchi disk, water temperature, redox potential and mineralization - using portable water quality control devices. In total, there were 23 herbarium collections at six monitoring sites. The results of research at permanent sites show that the diversity of aquatic plants in Chivyrkuy Bay remains high.
