Coupling Modern Portfolio Theory and Marxan enhances the efficiency of Lesser White-fronted Goose’s ( Anser erythropus ) habitat conservation

摘要: Climate change and human activities cause uncertain changes to species biodiversity by altering their habitat. The uncertainty of climate requires planners balance the benefit cost making conservation plan. Here optimal protection approach for Lesser White-fronted Goose (LWfG) coupling Modern Portfolio Theory (MPT) Marxan selection were proposed. MPT was used provide suggested weights investment protected area (PA) reduce influence climatic uncertainty, while utilized choose a series specific locations PA. We argued that through combining these two commonly techniques with plan, including assets allocation PA chosing, efficiency rare bird's would be enhanced. In analyses, conservation-outcome can reduced effort allocated in Hunan, Jiangxi Yangtze River delta. model, location habitat restorations based on existing nature reserve identified. Clear priorities could provided this research, it help decision makers build strategy LWfG.
