The Škocjan Caves are included in UNESCO's World Heritage List due to their outstanding natural features. The caves include a large underground canyon containing the Reka River, collapse dolines with vegetation in rock fissures and impressive archaeological sites with a rich history of speleological and scientific research. They are also included in the Ramsar Directory of Wetlands of International Importance. Together with their broader surface area, the site is known as the UNESCO Karst Biosphere Reserve. The aim of the management of the reserve is to protect the World Heritage Site and to preserve its outstanding universal value for future generations. The protection activities are regulated by the provisions of international documents, the Škocjan Caves Regional Park Act and the park's management plan. These activities include monitoring of the water quality in the Reka River and meteorological surveys on the surface. Monitoring of the microclimate of the caves focuses on measuring the effects of tourism and monitoring the levels of radon, with the aim of the ensuring the safety of the park's employees. Ensuring a favourable status for the underground habitats and species is laid down in the Natura 2000 management programme. Particular attention is paid to ensuring high-quality, safe visits to the caves and providing educational and awareness-raising activities on the surface of the park.
The goal of the present research was to assess the environmental worldviews and concerns of students from the fourth to the seventh grade in Slovenia. The New Ecological Paradigm Scale for Children was translated and validated for use with Slovenian primary school students (N = 310). The students were also asked about their environmental concerns (using statements from the Environmental Motives Scale) and demographic questions. A confirmatory factor analysis was conducted for the New Ecological Paradigm scale using AMOS software, confirming a three-dimensional model with ten items. The students showed the highest agreement with the items in the factor Rights of Nature, and the lowest agreement with Human Exemptionalism. The environmental attitudes of the students decreased from the fourth to the seventh grade, while altruistic environmental concerns significantly increased with higher grades. Gender differences were not statistically significant for environmental worldviews and concerns. The reported results show that biospheric environmental concern positively correlates with the factors Rights of Nature and belief in Eco-Crisis, and negatively correlates with Human Exemptionalism. The New Ecological Paradigm tool will enable the evaluation of education programmes for children in Slovenia.
Tourism activities in caves can result in changes in the microclimates of caves. The natural microclimate in closed caves is constant due to the balance between cave air and cave walls, while in open caves exchanges with outside air influence the microclimate. Visits to caves, especially in closed smaller caves, can thus endanger the natural balance if the microclimate does not return to natural conditions quickly enough.Continuous monitoring of the temperature and concentration of carbon dioxide in Škocjan Caves enables the assessment of the impact of visits. For this purpose, we used data measured in the relatively closed Silent Cave, at the locations named Calvary (Kalvarija), Tent (Šotor), and Passage (Prehod) in 2016, and in the wide open Murmuring Cave, at the locations named Bridge (Most) and Rimstone Pools (Ponvice), in 2013. The outdoor air temperature, as measured at the Škocjan meteorological station on the surface plateau, was considered in both cases. Along the tourist part of Škocjan Caves, the most closed part of the cave in Silent Cave is the location at Calvary, when the entrance doors through an artificially dug tunnel are closed. During the visits, the microclimate is subjected to draughts through open doors and to anthropogenic emissions. The data suggest that the influence of draughts predominates over direct anthropogenic emissions. In winter or on cold days air flows upwards and through the tunnel out of the cave, whereas in summer or on warm days it flows downwards. In such cases, the CO2 concentration decreases markedly due to the downwards chimney effect as the concentration in the outside air is much lower than in the cave. The data show that the temperature overnight and towards morning always returns to its natural value even in this rather small location in the cave. The changes in CO2 concentration persist for a longer period, until the time of the first visit the next morning, when it is again perturbed by a new visit. The data on time courses support the theoretically estimated characteristic of the exponential decline of disturbances backward towards natural conditions, depending on the size of a cave and on the efficiency of exchanges with its walls. For temperature, this characteristic time tT is about three to six hours at the Calvary site. The return of CO2 to natural conditions tCO2 is longer and its estimate less reliable than the one for temperature. In the wide-open and large Murmuring Cave, the impact of visits is negligible throughout the year. In this part of the cave we can observe the influence of external daily and annual changes, the amplitudes of which get smaller, and their phase lags bigger, deeper in the cave.
The UNESCO Man and the Biosphere programme has proven to be a highly efficient tool for the conservation of natural and cultural heritage and an incentive for efforts towards sustainable development at the Karst Biosphere Reserve in Slovenia. Since the Reserve was established in 2003, the Škocjan Caves Park Public Service Agency, as the managing authority, has gradually developed a system that attempts to link the scientific and research sphere to the local community, while actively involving the community in the Biosphere Reserve's long-term management through education, awareness raising and participatory approaches. Taking into consideration the human dimension in the environment is essential for the preservation and sustainable use of the ecosystem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
