| Popis: | A geodiversity assessment is one of the basic steps in the development of geoprotection activities. It is important to establish parameters that quantify the elements and locations of abiotic nature. Here, the focus is on those who are richer than the average population. In doing so, it is possible to manage areas for the protection of important geoheritage and develop sustainable activities, e.g., geotourism. The monitored territory (Slovenské rudohorie Mts.) lies in southeast Slovakia and occupies an area of 4986 km2. The geodiversity assessment is based on overlaying a grid onto different maps at a scale of 1:500,000, where the final geodiversity index is the sum of six indices calculated in 5 × 5 km grid squares. These indices consist of a geological index, a geomorphological index (composed of two sub-indices: geomorphological subdivision and morphological–morphometric types), a hydrological index (composed of three sub-indices: the type of aquifer, the density of the river network, and the occurrence of springs and mineral waters), a soil index, a tectonic index, and a mineral resources index (composed of four sub-indices: the occurrence of ore, non-ore, construction, and energy resources). The resulting geodiversity index map is presented in the form of five isoline classes: very high (10% of the monitored area), high (28%), medium (32%), low (23%), and very low (7%). The geodiversity map of the territory of the Slovenské rudohorie Mts., together with the indices, creates a useful tool for conservation, management, sustainability programs, and education at the national level. However, Slovak legislation does not mention the concept of geodiversity, its protection, valuation, restoration, or responsible usage. Only its specific forms and processes are preserved as a natural resource supporting biodiversity. Considering the mineralogical richness of the area, some locations with a very high geodiversity may be the focus of mineral exploration. It is very important to set up appropriate landscape management for these sites. Valuable geotopes located in biodiversity cold spots that are not subject to protection within the state’s nature protection program should be considered as small protected areas (up to 1000 ha) at the fourth or fifth level of protection under Act No. 543/2002 Coll. or could form the core areas of a possible Geopark. |
