Sažetak
The research area is southern slope of Svilaja mountain, situated in the interior part of central Dalmatia, Croatia. It is a typical karst landscape, with the considerable human impact in the human-environment interrelations. Coping with scarcity of water, soil and regular summer droughts, as main constraints related to Dalmatian karst, pastoralism has been the most adaptable economic activity and lifestyle throughout the centuries. Excessive pastoralism in the conditions of Mediterranean climate, thin soil cover and especially steep slopes eventually led to the deforestation. However, abandoning of land due to the process of litoralization in the littoral zone of Dalmatia in the second half of the XX.th century, initiated the process of natural succession and re-afforestation. The research is tracing the environmental and landscape change of southern slope of Svilaja mountain since the XIX.th century, through three main periods: initial (1830-1846), transitional (1975) and recent period (2004-2010). The application of GIS model in analysing the landscape change is based on the original cadastral sources (State Archives of Split, Map Archives of Istria and Dalmatia), on the Institute for Adriatic Crops and Karst Reclamation database and Hrvatske šume (Croatian Forests) database, on CORINE Land Cover Croatia, as well as on fieldwork data. Landcover has been the main criterion used in classification of the landscape types. The GIS model of landscape change is organized around three levels: 1. landscape types, 2. types of landscape change and 3.trends of landscape change. GIS technology enabled the comparison of main areas of landscape change and the areas of most intensive population pressure. Overall results show the importance of human impact in landscape change, both in the processes of degradation, deforestation, as well as re-afforestation, due to the depopulation and rural exodus, and in the process of deliberate reclamation and protection of previously degraded and eroded slopes.
