The study aims to identify and map the types of vegetation habitats with the indication of tree and palustrine species which had spontaneously developed in the last 30 years in Văcărești Natural Park in Bucharest. The park is surrounded by a concrete dam. The research was carried out on the surface of 156 ha within the dam. The vegetation mapping was done through visual analysis and interpretation of the satellite maps. The classification of the 11 identified habitats was made according to 2 major criteria: the tree coverage (groves, dense groups, isolated groups, herbaceous layer) and the percentage of soil moisture, evaluated according to the type of vegetation encountered (mesophytes, mesohygrophytes, hygrophytes). The results present the spatial distribution and percentage cover of each type of plant habitat and also their percentage cover regarding specifically soil moisture and vegetation structure, the value and the variation of EVI (Enhanced vegetation index) and NDVI (Normalized difference vegetation index). The mapping provides data for future studies regarding the ecological effect and for developing a conservation management plan for one of the largest urban wetlands in Europe.
