Approach to optimizing ecological monitoring of water quality using indicators of constancy of higher water vegetation (using example of upper course of White river in Bashkortostan Republic)

The article provides an analysis of the dynamics of the constancy indicators of representatives of higher aquatic vegetation (VBR) in the upper reaches of the Belaya River (Republic of Bashkortostan) from 2005 to 2019. Constancy indicators of 11 species of BBP (Butomus umbellatus L., 1753; Elodea canadensis Michx., 1803; Najas marina L., 1753; Potamogeton natans L., 1753; Potamogeton perfoliatus L., 1753; Potamogeton crispus L., 1753; Stuckenia pectinata L., 1753; Myriophyllum spicatum L., 1753; Lemna minor L., 1753; Spirodela polyrhiza Schleid., 1839 and Ceratophyllum demersum L., 1753) were registered in the areas of 2 state water posts - the Shushpa railway station and the Arsky Kamen recreation house. In the course of research, for the first time, lists of permanent, additional and random species of BBP were compiled, correlation-regression models of the relationships between the constancy indicators of representatives of higher aquatic vegetation with the content of chemicals were calculated, the pollutants most strongly affecting the constancy indicators of representatives of BBP were identified, determined in the water of the upper course of the Belaya River.
