Rarefied Ethnoecology: Mushroom Knowledge Erosion and the Limits of Digital Foraging Repopularisation in Selected Sites of the Italian Alps and the Former German Democratic Republic
Despite a contemporary revival in wild mushroom foraging driven by digital tools and renewed interest, this study of sites in the Italian Alps and former East Germany reveals a paradoxical "knowledge rarefaction" where deep, place-based ecological understanding is eroding due to generational discontinuity and rural depopulation, suggesting that information-based learning cannot fully replace the situated expertise developed through long-term human-forest engagement.
