Benefits of integrating complementarity into priority threat management

摘要: Conservation decision tools based on cost-effectiveness analysis are used to assess threat management strategies for improving species persistence. These approaches rank alternative by their benefit cost ratio but may fail identify the optimal sets of implement under limited budgets because they do not account redundancies. We devised a multiobjective optimization approach in which complementarity principle is applied that protect most any budget. our prioritize 53 conservation concern Pilbara, Australia. followed structured elicitation collect information benefits and costs implementing 17 different during 3-day workshop with 49 stakeholders experts biodiversity, conservation, Pilbara. compared performance priority current ranking approach. A complementary set 3 strategies: domestic herbivore management, fire research, sanctuaries provided all >50% chance persistence $4.7 million/year over 20 years. Achieving same result almost twice as much ($9.71 million/year) when were selected ranks alone. Our results show has potential double impact approaches.
