Abstract: Biodiversity is declining across Europe. Modern agricultural practices, habitat fragmentation, land abandonment and climate change are key factors causing current trends in environmental change. Mobile organisms such as raptors, positioned high in the food chain, are good indicators of negative or positive landscape dynamics, since their response is fast. This assumption was tested by investigating the Scops Owl (Otus scops) population in a traditional Central European cultural landscape (Goričko Nature Park [GNP]) in Slovenia. The negative trend in male calling Scops Owls was correlated with static and dynamic environmental change variables derived from remotely sensed or field-based, multi-temporal data sources. Key geospatial predictors were identified and used for bird calling and breeding (C&B) suitability modelling. All geospatial models developed predicted a decline in C&B suitability (even by 33%) in almost all areas where the bird is currently active. However, the NE part of the GNP could achieve better C&B conditions for theScops Owl in the coming years (a potential 36% increase in suitability). Predictions indicate that more effort and action, to conserve the Scops Owl in the study area should be implemented in the N, NE and E part of the hilly GNP. Our results are thus highly applicable not just for decision makers in this protected area but rather in all areas across the Scops Owl’s continental population, since the methodology is easily replicable and transferable.
