Sažetak
Plitvice Lakes are the oldest Croatian National Park, and in 1979 were listed on the UNESCO List of World Heritage. The basic phenomenon is the combination of waterfalls and 16 cascading lakes formed as a result of permanent biodynamic process of creation and growth of tufa. The lakes are surrounded by forest vegetation of a total area 25.000 ha under the Park's jurisdiction. Forests are very interesting and complex for phytocoenological research, primarily due to its preservation, geographical position which is characterized by intermediate forms of continental and Mediterranean, Alpine-Central European and Balkan-Illyrian vegetation, various environmental conditions and floristic composition, as well as numerous successional stages on deforested, mostly former agricultural land. Map of forest vegetation in scale 1:25.000 is made on the basis of SPOT satellite images (resolution 2.5 x 2.5 m). The field research included 424 plots (176 releves and 248 control points). Individual coordinates in the radius of 30 m for each forest community (habitat type) were set up as the learning field for supervised classification. "Maximum likelihood" method which is integrated within the program ArcMap 9.1. was used. The results of classification in raster format are simplified by using the tools of generalization and then transferred to the vector form (polygons). Some polygons are manually adjusted on the basis of detailed fieldwork and testing results of the classification. Software tools QGIS and ArcMap 9.1. were used. The final map is complemented by analysis of geomorphological factors and the use of previous geological, soil, climate and other research. On the vegetation map 30 cartographic units and 3 cartographic characters are presented. They are defined according phytocenological principles taking into account the recent situation concerning the dominant species and the manner of their foundation or domination. They are divided into 4 different groups: natural forest communities, successional stages, forest plantations and secondary forest stands of anthropogenic origin and general group with the addition of cartographic signs of dominance or significant presence of certain tree species.
