The role of forest vegetation in karst on soil protection from erosion
Land degradation has been recognized as a major environmental issue whose processes have been varying in places and time, within the Mediterranean basin. Forest management policies in this area have traditionally encouraged land cover changes, with the establishment of tree cover in natural or degraded ecosystems for soil conservation purposes: to reduce soil erosion and to increase the vegetation structure. In order to evaluate the role of forest vegetation on soil protection from erosion in Mediterranean landscapes we compared 4 vegetation cover types (Black pine-old and young culture, Oriental hornbeam shrublands and grass cover) monitored in 6 hydrological plots (2, 5 x 20 m) in the Suvava catchment (Dalmatia, S Croatia) during 7 years (from 2003 to 2009). Each cover type represented a different dominant patch of the vegetation mosaic of the catchment. The values obtained for the seven-year study period were compared with the values from the period since 1972 to 1975 year. The results showed that in mentioned period (2003-2009) the soil losses under young Black pine plots averaged 2.234 g m-2, old culture of Black pine 1.774 g m-2, grass cover 2.234 g m-2 and Oriental hornbeam shrublands 0.0516 g m-2. According to the literature data, runoff and erosion measured in 6 plots may be considered low. Flow off in the Suvava catchment slightly increased, while the soil loss was 3.7 times lower than in the previous period (1972-1975), when more than 50 % of the catchment area was without forest vegetation. Annual coefficients of runoff on the investigated types of vegetation cover are small and do not exceed 10 % of total annual rainfall. In line with this annual soil loss are also low, and erosion is completely excluded. Forest vegetation in the Suvava catchment has a significant and very positive role in protecting soil from erosion. Natural vegetation and/or afforestation is adequate method to prevent soil from erosion.
