The Application of Population Viability Analysis in the Conservation and Management of Endangered Wildlife

Population viability analysis(PVA) is one of the main methods to protect endangered species.After it had been proposed,PVA is mainly used in the prediction of extinction probabilities of endangered species.With the emergence of PVA software,its application has been further extended,and the abuse of PVA has appeared.As a result a discussion about its accuracy has emerged.However,most conservation biologists believe the PVA is significant in the protection of endangered species.At present,PVA primarily apply to the conservation and management of endangered species.We summarized the application of PVA in the making out and assessment of management strategies,the evaluation of reintroduction plans,and the design and management effective assessment of the Nature Reserves.We also discussed the data collection and the selection,establishment and application of models in the use of PVA.Based on the previous studies,we suggested,in the future,the PVA could be more concerned in the use of genetic data,the development of individual-based population models,inbreeding depression and decreasing the threaten of invasive species.
