Macrophytes of Shukralinka and Melekeska rivers
In September 2018, botanical studies were carried out in the watercourses of the city of Naberezhnye Chelny in order to determine the current environmental status of the Shukralinka (Chelna) and Melekeska rivers. The analysis showed a satisfactory condition of watercourses, expressed in high species richness (70 species) and diversity of macrophytes, especially in the Melekeska river. The analysis showed a small participation of alien and adventive species. The saprobity index showed that most of the surveyed water areas can be attributed to the β-mesosaprobic zone of moderately polluted waters.
