5. Developing National Forest Inventory-based indicators for monitoring minority ravine forestsAnže Martin Pintar, Janez Kermavnar, Luka Krajnc, Gal Kušar, Lado Kutnar, 2026, izvirni znanstveni članek Povzetek: Ravine forests represent a priority habitat type of the European Natura 2000 network for which empirical data are limited, particularly regarding the influence of stand structure on biodiversity. Assessment of forest habitats can largely be supported by National Forest Inventory (NFI) data, which enable frequent and spatially dense monitoring of the stand conditions and potential vulnerability of forest habitat types. In this study, we established an independent, nationwide classification system of close-to-nature managed ravine forests dominated by different characteristic broadleaf trees, based on stratifying NFI data into homogeneous subtypes. On the basis of tree species composition, which is a basic component in forest habitat types, we identified three subtypes of ravine forests, dominated by Acer pseudoplatanus, Fraxinus excelsior, and Tilia spp. We examined these subtypes using structural, compositional, deadwood, and diversity-related indicators. The Tilia-dominated subtype was more common in the lower altitudinal belt (≤ 502 m), while the Acer-dominated subtype was more prominent in the higher belt (> 502 m). The Acer-dominated subtype predominated in stands with SDI lower than 432, while the Tilia-dominated subtype was relatively more common in stands with higher SDI. In stands with Evenness values lower than 0.3, the Acer-dominated subtype predominated, while in stands with higher Evenness index values, the Fraxinus-dominated subtype was more common. In the Fraxinus-dominated subtype, the volume of standing dead trees was statistically significantly higher than in the other two subtypes (14 m3 /ha compared to 8 m3 /ha) due to the high mortality rate of trees caused by ash dieback. In all three subtypes of ravine forests, we observed a lack of natural regeneration of key tree species, which is crucial for maintaining the favorable conservation status of the habitat type. The observed ranges of structural and compositional attributes, deadwood components, and diversity indices provide empirical reference conditions that reflect the current nationwide variability of ravine forests.

6. Integrated multi-scale ecohydrogeological monitoring of spatio-temporal dynamics in karst critical zonesNataša Ravbar, Metka Petrič, Mitja Ferlan, Uroš Novak, Janez Kermavnar, Lado Kutnar, Aleksander Marinšek, Daniel Žlindra, Blaž Kogovšek, Erika Kozamernik, Cyril Mayaud, David Štefanič, Sara Skok, Janez Mulec, Stanka Šebela, Urša Vilhar, 2026, drugi znanstveni članki Povzetek: Contemporary environmental concerns highlight the vulnerability of karst environments to changing hydrometeorological patterns and vegetation disturbance, necessitating a unified, interdisciplinary strategy for comprehensive understanding. This paper critically examines the current state of research. To overcome the identified gaps, it presents an integrated multi-scale ecohydrogeological monitoring approach tailored to karst critical zones (KCZ) and its spatio-temporal variability. Forested karst aquifer in Slovenia is used as a case study to demonstrate and assess the strengths and limitations of the proposed monitoring framework. To decipher flow dynamics and propose customized data collection strategies the approach combines surface and underground sites and employs advanced methods adapted to the challenges of karst environments. The results highlight the benefits and advancements of monitoring and sampling approaches to ensure representativeness in heterogeneous environments. The focus is on the use of enhanced precipitation monitoring systems to expand sampling areas nearly fivefold and improve precipitation and throughfall measurements. Additionally, customized lysimeter techniques for karst soils and microscale adaptations for cave exploration have been developed, addressing the challenges of instrument placement in environments with significant variability. Further opportunities lie in improving instrument protection, integrating sensor networks, combining remote sensing and scaling from plot to aquifer level. However, challenges remain in achieving spatio-temporal representativeness and ensuring the operational reliability of snow monitoring, soil solution sampling and drip flow measurements. Threats include environmental pressures and hydrometeorological conditions, equipment tampering and funding stability. Nevertheless, this comprehensive approach improves monitoring of ecohydrogeological processes in the KCZ, promotes interdisciplinary collaboration and environmental resource management.
