安徽贵池老山省级自然保护区鸟类资源调查OA

[Objective]To understand the bird species and their distribution in the Anhui Guichi Laoshan Provincial Nature Reserve.[Meth-od]A systematic survey was conducted from 2022 to 2023 using line transect methods,point transect methods,and literature review.[Result]A total of 201 species from 16 orders and 50 families were recorded.The regional analysis revealed that 38 species(18.91%)belong to the Palaearctic region,while 94 species(46.77%)belong to the Oriental region,indicating a clear north-south transition.Resident birds make up the majority(89 species,44.28%),with 22.89%,15.42%,and 17.41%being summer migrants,winter migrants,and passage birds,respectively.The protected species include 2 nationally I-class key protected birds(Syrmaticus ellioti and Emberiza aureola),34 II-class pro-tected species,and 158 nationally"three-valued"(with significant ecological,scientific,and social value)protected animals(78.6%).[Conclusion]Habitat fragmentation is the primary threat,and it is recommended to enhance conservation efforts through habitat corridor con-struction,optimization of intelligent monitoring networks,and community co-management mechanisms.
