Methods for soil enhancement in geoheritage research : a case study from Veglia-Devero Natural Park (Lepontine Alps) / A. Masseroli, I.M. Bollati, L. Trombino, M. Pelfini. ((Intervento presentato al convegno EGU General Assembly tenutosi a online nel 2021.
Abstract:
In mountain environments, the high variability of soil forming factors (i.e., parent material, climate,
relief, organism, time) is responsible for the presence of different soil types, which not only
contribute to the pedodiversity but are also a component of the local cultural heritage.
Up to now, scarce attention has been paid to the soil in the geoheritage/geoconservation scientific
analyses.
To promote soil as element concurring to mountain geoheritage definition, we propose a strategy
to include pedological topics within a multidisciplinary trail planned in the Veglia-Devero Natural
Park (Lepontine Alps). The geomorphological dynamicity and environmental change affecting
during times the small mountain catchment of Buscagna hydrographic basin are illustrated with a
specific address to soil characteristics. The physical and chemical properties, and pedological
features of soils reflect the interaction among the other ecosystem components (i.e. geology,
geomorphology and vegetation), underlining the role of soil as natural archive for reconstructing
landscape evolution and for achieving a more complete assessment of Late Quaternary
geomorphic events, especially surface processes.
Geopedological researches carried out in the study area, allowed to detect 7 soil profiles as
potential sites of pedological interest, located in safe and accessible places, along already existing
hiking paths. The selected soil profiles not only mirror the main soil types that characterize the
area but also represent evidence of past environmental conditions and geomorphic dynamics.
The opportunities for hikers and mountaineers, to observe the exposed soils along the Buscagna
valley, thanks to the presence of erosional scarps and subsidence areas, allow also to get more
awareness of the need of geoheritage conservation strategies addressed to soil, especially in the
mountain landscape where soil characteristics reflect the striking influence of its forming factors.
