In the Giant Mountains National Park there is a high concentration of karst phenomena (especially caves, dives, karst canals and small cavities) bound to small bodies of carbonates. So far, however, these phenomena have not been studied comprehensively, but have always been focused on a particular problem. Based on the measures of the KRNAP Care Plan and its OP 2010-2020, the submitted project is tasked with inventorying and documentation of caves and small karst and pseudocrastic shapes.
