Study of aquatic macrophytes in the wetlands on the territory of Vrachanski Balkan nature park

An overall study of the species composition and abundance of macrophytes in all open water bodies of a large protected territory was made for the first time in Bulgaria. Four high-mountain eutrophic lakes and the upper stretches of three rivers within the boundaries of Vrachanski Balkan Nature Park were investigated. Thirty-nine macrophyte species (higher plants and mosses) were identified scattered around, or forming more or less distinct vegetation groups. Three of the lakes are new for the country locations of the species Elatine alsinastrum and Peplis portula. The processes of eutrophication are more advanced in the lakes. The habitats formed around the investigated water bodies have been determined. They are three habitats of European Community interest for Bulgaria. The major threats for the investigated wetlands on the territory of the Park are pointed out.
