Abstract: Climate change and declining economic revenues are driving the closure of many ski resorts in mountainous regions worldwide, particularly at lower elevations, where winter snow cover is becoming increasingly sporadic. This abandonment is impacting wide areas of the Alps, previously managed to reduce erosion and to control trees/shrubs encroachment. As result, natural rewilding processes may lead either to the environmental degradation or to the restoration of pre-disturbance conditions, each with different implications for sustainability. Our aim was to assess the rewilding state and the drivers of sustainability at an abandoned ski resort in the Italian Alps (Valcanale, Bergamo), where the ecosystem has been evolving under minimal human pressure since the ski facilities were decommissioned in 1993. The assessment focused on pedological/vegetational perspectives, with particular attention to soil-based ecosystem services (SBESs). The results show that the interventions made during ski run construction significantly influenced the recovery of SBESs (and thus their long-term sustainability). Areas with minimal disturbance (e.g., forest vegetation removal without soil movement) now support SBESs at levels comparable to nearby undisturbed areas. Conversely, ski runs that underwent slope reshaping/grading support poorly developed soils and significant sheet/gully erosion, rendering them hazardous for pedestrians. Nevertheless, plant biodiversity has benefited in some cases, as many rare/endemic protected species colonize stony/eroded ski runs soils, extending their distribution beyond their original habitat.
