Bird diversity is often used as surrogates for other species diversity,but there is a limited understanding of the extent of this surrogate in identifying representative priority conservation areas(PCAs).We used Yunnan Province in China as a case to measure the surrogacy of birds in systematic conservation planning.Here,we collected distribution records of mammals,amphibians,reptiles,and birds from public databases and literature,and applied systematic conservation planning methods to identify PCAs.We targeted four taxonomic groups at conservation targets of 17％,31％,and 50％of the total study area,and used the Jaccard similarity index to evaluate the surrogate extent of bird PCAs for the other three groups.Then,we overlapped different portfolios of PCAs with six categories of protected areas(PAs)in Yunnan,calculated the protection rates,and evaluated the effect of sustainable-use PAs on improving the protection rate of strict Nature Reserves.The results showed that bird PCAs generally had the highest surrogacy for representing PCAs of the other three taxa.At the 50％conservation target,the Jaccard indices between birds and the other taxa reached about 0.50.Moreover,amphibian PCAs had a good surrogacy for conserving reptiles,with a Jaccard index of 0.30,0.44 and 0.51 at the 17％,31％and 50％conservation targets,respectively.The existing PA system had quite low coverages for PCAs of these four taxa,and the average protection rates were 22.97％,19.78％and 16.52％at the three levels of conservation targets,respectively.The sustainable-use PAs can greatly complement the strict Nature Reserves by achieving average increased PA coverages of 10.00％,9.20％and 7.90％at the three conservation targets.Our findings provide a basis for surrogate-based conservation planning for areas with insufficient biodiversity information.
