Sažetak
Due to the cessation of anthropogenic activities, many mountain and island grassland begins growing into scrubs and forests. It comes to the process of secondary progressive succession so plants adapted to open habitats disappear. NATURA 2000 prescribes various measures to conserve these endangered habitats precisely in order to preserve the biodiversity of vegetation areas. The study has determined the qualitative and quantitative changes in the last 40 years in the vegetation cover of the Telašćica and Vransko jezero Nature Parks. The analysis was made by comparing the historical vegetation maps made at the level of association and recent habitat maps of Parks mapped on different levels. Aligning thematic differentiation of used maps was done adjusting classes to the lowest common level. Overall analysis was done using the computer programs SAGA GIS and Excel. In the area of Telašćica Nature Park grasslands have decreased by 32.97 % of total Park area, with a grasslands significantly reduced (by 51.51 %) with respect to the initial area, and transitional grasslands / scrubs have increased by 27.88 % of total Park area (1620.76 % increase in the level type). The directional change analysis confirms that the 32.78 % of grasslands overgrown with transitional grassland / scrubs, 45.43% remained in grassland type, while changes to other types were recorded in smaller percentages. Mediterranean scrubs are degraded with transitional grasslands / scrubs by 27.03 %, 24.32 % remained in the type of scrubs, and 27.03% was overgrown with trees and underbrush. In the area of Vransko jezero Nature Park grasslands have decreased by 16.31 % of total Park area, with a grasslands markedly decreased (by 94.78 %) with respect to the initial area, and scrubs have increased by 25.41 % of total Park area (3104.30 % increase in the level type). The directional change analysis shows that all of the grasslands crossed to a different vegetation type, and most in the trees and underbrush, by 24.96%, and 53.76% of cultivated areas crossed into scrubs. This study clearly confirmed the significant processes of secondary progressive succession in the Telašćica and Vransko jezero Nature Parks, indicating the necessity of implementing essential measures to protect grassland habitats.
