Other Site Characteristics

In the village of Velika Gradusa there is a cave Gradusa, the total length of 455 meters. There was a formation of underground cavities in the process of karstification rocks are formed by deposition of sediments that once covered the region. The cave entrance is from an abandoned quarry. The cave is clear the main channel direction of NW-SE. The cave itself and the surrounding area is important for the conservation of bats. Lithostratigraphic units represented in this area are carbonate flish and clastic rocks (Pc, E), badenian lithothamnium limestone and clastic sediments with volcanic rocks, miocene clastic rocks and carbonate with clastic rocks, pliocene paludian deposits and clastic deposits. Area has a complex structure of morphogenetic types of relief and complex orographic structure as a result of dynamic geotectonic relations, hydrogeological conditions, climate and anthropogenic influences with presence of fluvial and slope processes. Dominant soils are eutric cambisols, rendzic and stagnic, gleyic podzololuvisols.

4.2 Quality and importance

- site represents important site for bats - Gradusa cave also represents important habitat for other aquatic and terrestrial underground taxa because it is isolated - important Miniopterus schreibersii nursery - important Rhinolophus euryale, Rhinolophus ferrumequinum and Rhinolophus hipposideros migration and feeding site - internationally important underground site for Rhinolophus euryale and Miniopterus schreibersii
