Can agro-ecosystems efficiently complement protected area networks?

摘要: Threats to biodiversity are often enhanced in human-dominated and densely-populated regions. The prospects for establishing new protected areas generally more limited such regions, due competition with other land-uses. Improving the conservation value of agricultural lands has been proposed as a complementary strategy. Our goal was compare alternatives expanding an existing area system. We used planning software Marxan select candidate sites addition system, based on following three strategies: (1) focusing remaining natural habitats; (2) prioritizing wildlife-friendly farming agri-environmental measures that can improve value; (3) strategy combining former two. surrogate cost aim minimizing total needed meet our objectives. evaluated found via each respect their landscape structure coverage they provided target species’ habitats. focused breeding bird species Israel’s Mediterranean region, challenging relevant case study area’s high level urbanization, population density, its heterogeneous landscape. adequate only 23% species, clearly demonstrating need action.
