Does re-wilding contribute to biodiversity conservation in Mediterranean cultural landscapes?
摘要
Debate has arisen on the use of “re-wilding” to promote biodiversity conservation. We contend that approaches aiming for strict non-intervention to restore “wilderness” may be conceptually inconsistent when applied to human-shaped landscapes. Several ecosystems of high biodiversity value, often misclassified as “pristine” have been shaped over millennia of human use, a context rarely acknowledged by re-wilding approaches. Rural abandonment in Europe is seen as an opportunity to promote biodiversity conservation through “re-wilding”, but management neglect may favor forest species at the expense of open-habitat species. In Mediterranean regions, where cultural ecosystems have high conservation value, management neglect may reduce biodiversity and increase wildfire hazard, especially under climate change. Using three Mediterranean basin case studies, we argue that wilderness-focused re-wilding, if applied uncritically, can have unintended negative consequences. While recognizing the diversity of re-wilding concepts, we highlight the need for context-specific strategies, where active management remains essential.
