Carcass Provisioning to Support Scavengers: Evaluating a Controversial Nature Conservation Practice

摘要: A number of scavenger species have suffered population declines across Europe. In attempts to reverse their decline, some land and wildlife managers adopted the practice leaving or placing out carcasses wild domestic herbivores provide a source carrion. However, this can be controversial practice, with as yet unclear outcomes for many target ecosystems they are part of. Here we bring key aspects increasingly common conservation illustrated using three contrasting cases studies. We show that provision is often motivated by desire benefit charismatic facilitate nutrient cycling throughout an ecosystem. Evidence effectiveness in achieving these objectives, however, mostly lacking, ecologists studying “easier” groups such beetles therefore not providing relevant insights. Moreover, conflicts between environmental policies carcass provisioning aimed at other social economic objectives do occur but projects designed without taking into account broader context. conclude expecting simply “good biodiversity” may too naive view. greater knowledge impact placement on society large required before it become more effective tool wider scale.
