Soft-water lobelia lakes in Poland

Dariusz Borowiak , Piotrowicz Ryszard , Kamil Nowiński , Piotr Klimaszyk


The lobelia lakes, unique and rare in Poland, are located mainly in northern part of country in moraine plateaus of Bytów and Kashubian Lakelands and outwash plains of Tuchola Forest and Charzykowy. In the middle of the twentieth century, there were over 190 lobelia lakes in Poland. Lobelia lakes are classified as so-called soft-water lakes due to low concentrations of calcium and magnesium. Their waters are weakly buffered and usually have acid reaction and also small amount of biogenic elements. Lobelia lakes are overgrown by specific plant species – isoetids – adapted to the poor habitat: Lobelia dortmanna, Isöetes lacustris, Littorella uniflora and several other accompanying species. The lobelia lakes in Poland are prone to degradation and loss of their unique values. The most serious threats include acidification, humification deposition, alkalinization, eutrophication by agricultural activities or recreational use and lowering of water level induced by climate changes.
