Pannonian-Balkanic turkey oak forests are part of the Natura 2000 protected sites in Slovakia and thus need the proper identification and regular monitoring. We are required, as a country to monitor and report on the size, quality, and changes in these habitats. Remnants of forest habitats of various shapes and sizes of pannonian-balkanic turkey oak forests should be under periodic monitoring because they are the most endangered forest communities and are among the most species-rich in central Europe.

Here we focus on identifying and monitoring the Natura 2000 forest habitats in various forest fragments of pannonian-balkanic turkey oak habitats. The main aim of our study is to apply advanced remote sensing techniques to map the shape and size of vegetation units. We focused on identifying the habitats only by using multispectral satellite data Sentinel-2. The obtained data by the GPS tracking in the field were compared with the data from semi-automatic and automatic segmentation using the NaturaSat software. We recorded the relevés in the core and in the edge area of each patch and we analyzed the functional species, and groups, as monitoring of the recent herb layer composition.

Pannonian-Balcanic turkey oak forest fragments are suitable for the segmentation, and also keep the species composition relatively stable from the core area to the edge. This approach could be used for precise and regular monitoring by combining remote sensing techniques and fieldwork. This perspective could serve for the preparation of regular reports on shape and size changes.
