Abstract This paper explores the erosion of foraging-related ethnobotanical knowledge in three coastal Mediterranean areas: Gozo Island (Malta), Kasos Island (Greece), and the Castagniccia region of Corsica Island (France). Based on recent ethnobotanical fieldwork between the summer of 2023 and the spring of 2025 in the three study areas, we document the few remaining wild vegetable uses in each region and contextualise the absence of robust LEK linked to plant foraging within broader socio-environmental changes. Our findings show that land abandonment, mass migration, desertification, and the rise of seasonal tourism have contributed to the disintegration of Local Ecological Knowledge (LEK). These forces have severed communities from everyday land-based practices, transforming vibrant ethnobotanical traditions into fragmented memories. We argue that LEK, particularly foraging knowledge, cannot survive in the absence of continuous interaction with the landscape, and that the revival of such practices requires more than nostalgic return, demanding a reconnection with local agro-ecological systems.
