Diversity and Dynamics of “Vransko Jezero” Nature Park Habitats

Habitat diversity of “Vransko jezero” Nature Park is result of long-term interaction of three main factors, namely: climate ; water on habitat and human activities. In the dependence of their intensity, particularly man-made impact, habitat types and their areas has been continuously changed, through successional stages and habitat replacement. Both processes continuously contribute to habitat dynamics and shifts in their diversity. Quantifying those changes, based on available historic and recent data (vegetation and habitat maps) is not straightforward because of different spatial and thematic resolution used. Despite that, it is possible to determine that, in areas that are not influenced by water, secondary succession directed to climatogenic vegetation was dominant process taking place in habitat dynamics. However, in recent years replacement of habitats has increased locally, primarily by planting (and restoration) of olive orchards, that were with grassland - habitat types with highest regression. Unfortunately, majority of newly planted and restored olive orchards is intensively managed ones whose importance for biodiversity is significantly lower than that of traditionally managed ones that continues to decrease in area, as well as rocky pastures. This suggests that traditional way of land use is necessary to conserve the habitats diversity, hence the complete biodiversity.
