This study investigates the flora of 20 oxbow lakes in the Warta valley near Uniejów, ten of which are situated between the river-bed and the flood embankment, and ten are behind the flood bank. 152 plant species have been identified in the studied area: 112 within the embankment, and 148 outside of it. The plants include Nymphaea alba, Lemna gibba and Wolffia arrhiza, as well as Dianthus superbus and Thalictrum lucidum on the banks. The flora of oxbow lakes behind the flood bank includes a greater proportion of anthropofites and more synanthropic vegetation than inside the embankment. To prevent further synanthropisation of the flora, a buffer zone should be created around the oxbow lakes consisting of semi-natural meadow vegetation and single trees. All natural water reservoirs should come under legal protection as ecological lands.

The unprecedented bloom of “golden algae” Prymnesium parvum in the Oder River in 2022 was the worst ecological disaster in Poland and Germany in decades. In 2023, the penetration of those “killer algae” from the Gliwice Canal, as well as the Czernica and Januszkowice reservoirs into the main stream of the Oder River has been stopped by the Polish Waters. The article presents the current state of knowledge about this catastrophe and draws conclusions from pioneering tests conducted in Poland on methods to mitigate blooms in flowing waters (in the Gliwice Canal). Additionally, this work compiles and presents foreign methods of combating “golden algae” in fish ponds, in areas valuable for nature, sailing and fishing, as well as fauna restitution (including Unionidae mussels, significant for both the economy and for nature protection) following a mass bloom of P. parvum.

Bezprecedensowy zakwit „złotych alg” Prymnesium parvum w Odrze w 2022 r. był najgorszą klęską ekologiczną w Polsce i Niemczech od dekad. W 2023 r. udało się powstrzymać przenikanie „glonów-zabójców” z Kanału Gliwickiego, jak również zbiorników Czernica i Januszkowice do głównego nurtu Odry. Artykuł przedstawia aktualny stan wiedzy o tej katastrofie oraz wnioski z przeprowadzonych w Polsce, pionierskich testów metod wygaszania zakwitów w wodach płynących. Ponadto w niniejszej pracy zebrano i przedstawiono zagraniczne sposoby zwalczania „złotych alg” w stawach rybnych, na obszarach cennych dla przyrody, żeglarstwa i wędkarstwa, jak również restytucji fauny (w tym małży skójkowatych, istotnych tak dla gospodarki, jak dla ochrony przyrody) po masowym zakwicie P. parvum.
