Lakes are an important ecosystem for organisms living in or beside them and humans. Growth of macrophytes depends on several physical, chemical, hydromorphological and biotic factors. They have several adaptations that allow them to inhabit different habitats in the lakes. In this thesis, we assessed the presence and abundance of macrophytes in lake Črnava in Preddvor municipality and Lake Zbilje in Medvode municipality. We also measured several chemical and physical parameters, such as water temperature, concentration of oxygen, saturation with oxygen, and pH, and assessed environmental parameters. We analysed the concentration of orthophosphates and nitrates in the water. 26 taxa of macrophytes were recorded in both lakes. These taxa were recorded in ten transects on Lake Črnava and 26 transects on lake Zbilje. The most common species in both lakes was the Canadian waterweed (Elodea canadensis), representing over 90% of all relative plant abundance in lake Črnava. Physical and chemical parameters of water and environmental factors did not statistically significant effect macrophyte diversity.
