Lakes in the nature reserves of the Zaborski Landscape Park (Northern Poland)

Abstract

The aim of the work was to obtain new scientific information about four lakes that are under high legal protection in the form of nature reserves. These are very rare oligotrophic lakes in Poland, located in the Zaborski Landscape Park, which is also the buffer zone of the Bory Tucholskie National Park. These reserves, which belong to the aquatic kind, have unique vegetation. In the context of climate change, and therefore hydrological change, including the development of lake aging processes, data on the characteristics of the physicochemical properties of their basins and the waters within them are necessary. Therefore, bathymetric plans of the lakes and morphometric parameters were developed and selected water features were determined. In addition to the results obtained from field research, the work was enriched with data from the literature.
