Native predators reduce harvest of reindeer by Sámi pastoralists

摘要: Contemporary efforts to protect biological diversity recognize the importance of sustaining traditional human livelihoods, particularly uses land that are compatible with intact landscapes and ecologically complete food webs. However, these often confront conflicting goals. For example, conserving native predators may harm pastoralist economies because consume domestic livestock sustain people. This potential conflict must be reconciled by policy, but such reconciliation requires a firm understanding effects on prey used We long-term, large-scale database Bayesian models estimate impacts lynx (Lynx lynx), wolverine (Gulo gulo), brown bear (Ursus arctos) harvest semi-domesticated reindeer (Rangifer tarandus) Sami pastoralists in Sweden. The average annual averaged 25% population (95% credible interval = 19, 31).
