• Tourism development of Vilenica and Škocjan caves according to reports by alpine societies and guides in the second half of the 19th century

  A notable shift in the tourism development of Škocjan Caves and Vilenica occurred in the late 19th century, driven by the efforts of alpine societies. By the 1880s, these caves transitioned under the administration of specialized cave sections—Vilenica under the Italian section and Škocjan under the German-Austrian section—marking a pivotal moment in their tourist promotion. This study highlights how these societies, through systematic research activities and strategic initiatives, positioned the caves as significant tourist attractions during this period.

• Forest vegetation in the Reka gorge between the villages Škoflje and Škocjan (Škocjan Caves Regional Park) / Gozdna vegetacija v soteski Reke med Škofljami in Škocjanom (Regijski park Škocjanske jame)

  A comprehensive phytosociological study of the Škocjan Caves Regional Park identifies six distinct forest and shrub communities along the Reka River gorge, including three newly described subassociations of the Lamio orvalae-Alnetum glutinosae association. This research provides a validated description of the previously provisionally characterized Corydalido ochroleucae-Ostryetum carpinifoliae, enriching the understanding of riverine forest syntaxonomy in southwestern Slovenia. The study also highlights marginal sites with unique ecological characteristics, contributing to the broader knowledge of Natura 2000 habitats.

• Geological structure of karst stratigraphical windows at Škocjan Caves, Slovenia

  Research at Škocjan Caves, Slovenia, introduces the concept of 'karst stratigraphical windows' to describe surface exposures of older carbonate strata due to karst processes and collapse dolines. This discovery highlights how detailed geological mapping in karst areas can uncover hidden stratigraphic boundaries, providing deeper insights into subsurface structures. Unlike tectonic windows, these features arise from karst erosion and doline formation, offering a new perspective on understanding geological layers in regions with limited outcrops. The study emphasizes the importance of examining collapse dolines during surface mapping to enhance the comprehensiveness of geological data.

• Impact of visits on the microclimates of caves, Experimental evidence from Škocjan Caves

  Visits to caves, particularly in closed smaller ones, can disrupt their natural microclimates if disturbances do not quickly revert. Research at Škocjan Caves reveals that while temperature recovers within 3-6 hours post-visit due to efficient exchanges with cave walls, CO2 concentration disturbances persist longer, influenced more by draughts than direct emissions. In contrast, the impact of visits is negligible in wide-open caves like Murmuring Cave, where external changes dominate. The study used continuous monitoring data from 2013-2016 to assess temperature and CO2 dynamics, providing experimental evidence for theoretical models on microclimate recovery.

• Spatial planning of tourism in protected nature areas in Slovenia and the tourism carrying capacity of Škocjan Caves Regional Park

  Sustainable tourism in protected nature areas, such as Slovenia's Škocjan Caves Regional Park, hinges on integrated spatial planning and collaboration between management bodies and local communities. Research reveals that effective regulation requires regional spatial plans, particularly for areas spanning multiple municipalities. This approach ensures balanced development while preserving ecological integrity, as demonstrated by analyzing adopted spatial acts in Slovenian protected areas.

• Speleotourism in Slovenia: balancing between mass tourism and geoheritage protection

  Slovenia, recognized as the birthplace of karst geotourism, has over 12,000 caves, with 22 designated as tourist sites. A study using the M-GAM model assessed 10 of these caves to inform future management strategies. Key findings reveal that visitors prioritize natural values and prefer caves with minimal infrastructure, emphasizing protection status. The research highlights the pivotal role of Postojna Cave and Škocjan Caves in geotourism, with Škocjan's regional park management serving as a model for balancing mass tourism and geoheritage preservation.

• Spacio-Temporal Distribution and Tourist Impact on Airborne Bacteria in a Cave (Škocjan Caves, Slovenia)

  A strong positive correlation exists between tourist numbers and the concentration of airborne bacteria in the Škocjan Caves, with bacterial levels rising significantly during periods of high river discharge. The study, conducted using MALDI-TOF MS to identify cultivable airborne bacteria, found a mix of human-associated and natural habitat bacteria, including some from Risk Group 2. Despite dynamic cave climate conditions, large chambers did not show enhanced bacterial concentrations. This research highlights the impact of tourism on cave microbiota and underscores the complexity of microbial dynamics in visited caves.

• Medical Survey of the Staff Working in Škocjan Caves

  A five-year study at Škocjan Caves, Slovenia, reveals that prolonged exposure to radon radiation and other microclimatic factors—such as temperature, humidity, and air flow—can induce physiological changes in cave workers. The research, conducted by the Institute for Occupational Safety, Ljubljana, combines continuous radon monitoring with precise tracking of staff time spent underground, enabling accurate estimation of annual radiation doses. To mitigate health risks, the study implements regular medical surveys, including blood tests, as mandated by national regulations. These measures aim to prevent potential health issues while providing insights into the broader impacts of cave microclimates on human physiology.

• Gnezdilke Parka Škocjanske jame (Kras, JZ Slovenija)/ The breeding birds of Škocjan Caves Park (Kras, SW Slovenia)

  A comprehensive survey of breeding birds in Škocjan Caves Park, conducted between 2011 and 2012, identified 49 breeding species within the park's boundaries, including several of conservation significance. The study highlighted the presence of key species such as the Blackcap (Sylvia atricapilla), Robin (Erithacus rubecula), and Marsh Tit (Poecile palustris), with population estimates ranging from 200 to 320 breeding pairs for the most abundant species. Notably, the park hosts one of the largest colonies of Alpine Swifts (Apus melba) in Slovenia, a rare and localized species. Additionally, species such as the Peregrine Falcon (Falco peregrinus), Nightjar (Caprimulgus europaeus), and Scops Owl (Otus scops) were identified as qualifying for the Special Protected Area (SPA) Kras. The study used territory mapping for common species and species-specific methods, including observation, playback, and line transect techniques, to survey rare or nocturnally active birds.

• New Approaches to Understanding the World Natural and Cultural Heritage by Using 3D Technology: UNESCO's Škocjan Caves, Slovenia

  Škocjan Caves exemplify the interconnectedness of natural and cultural heritage through their karstic landscape. This study demonstrates that caves are integral to the broader surface landscape, challenging traditional isolation in documentation. By employing 3D technology, researchers integrated cave records with surface data, revealing how anthropogenic processes have shaped the landscape over time. The approach offers a novel methodology for understanding complex heritage systems, where natural and human activities coexist dynamically.
