20.500.12556/DiRROS-29526 Projekt EARTHONE in pilotna ploskev na Krasu: spremljanje prehoda rabe tal, talnih procesov, vegetacije in tokov ogljika v submediteranskem krasu Prispevek predstavlja zasnovo pilotne lokacije na območju slovenskega krasa v projektu EARTHONE (Environmental Analysis and Resilience for Transformative Human-Optimized Natural Environments), ki je usmerjen v spremljanje vplivov rabe tal in sprememb rabe tal na tla, pestrost talne mikrobiote, vegetacijo, mikroklimo, fenologijo in ogljikove tokove. Slovenski pilot je umeščen na območje Črnotič oziroma Podgorskega Krasa, kjer se v isti krajini pojavljajo odprti (aktivni) pašniki in travniki, zaraščajoče se površine ter manjši gozdni sestoji s puhastim hrastom (Quercus pubescens). Zaradi plitvih, skeletnih in prostorsko zelo heterogenih kraških tal je območje izrazito občutljivo na sezonsko sušo, kljub razmeroma visoki letni količini padavin. Raziskava izhaja iz dveh hipotez: (i) da sukcesijski prehod od odprte rabe proti gozdu spremeni mikroklimo, talno vlažnost, organsko snov in tokove CO₂ ter da (ii) različne oblike rabe in opuščanja vplivajo na rastlinsko sestavo, talno biološko aktivnost in fenološke odzive. Predvidene meritve vključujejo talne analize, vegetacijske popise, fenokamere, mikroklimatske senzorje, meritve tokov toplogrednih plinov (CO₂) ter analize talnega mikrobioma. Pilot bo prispeval k razumevanju kompromisov med ohranjanjem odprtih kraških habitatov in dopuščanjem naravne sukcesije. This contribution presents the design of the Slovenian Karst pilot within the EARTHONE project (Environmental Analysis and Resilience for Transformative Human-Optimized Natural Environments), which focuses on the effects of land use and land-use change on soils, soil biodiversity, vegetation, microclimate, phenology and carbon fluxes. The Slovenian pilot is located in the Črnotiče Podgorski Kras area, where open pastures and meadows, woodyencroached areas and Quercus pubescens forest stands occur within the same landscape. Due to shallow, stony and spatially heterogeneous karst soils, the system is highly sensitive to seasonal drought despite relatively high annual precipitation. The study is based on two hypotheses: first, that the successional transition from open grassland or pasture through woody encroachment to forest modifies microclimate, soil moisture, soil organic matter and CO₂ flux dynamics; and second, that different land-use and abandonment stages affect plant composition, soil biological activity and phenological responses. The planned monitoring includes soil analyses, vegetation surveys, phenology cameras, microclimate sensors, greenhouse-gas flux measurements and soil microbiome analysis. The pilot will support the assessment of trade-offs between conserving open karst habitats and allowing natural succession.
