Abstract: Puzhehei occupies an important position in the karst landforms in southwest of Chian.The reserve is a unique wetland ecosystem formed by karsts and lakes.It belongs to the Pearl River Basin and the Xijiang River System and has rich biodiversity.From March 2018 to January 2019,8 sample lines were set up in the protected area based on the sample line method,and 4 surveys were conducted.The results of this study show that there are 129 species of birds recorded in Puzhehei Nature Reserve,belonging to 18 orders and 49 families,of which 33 species of waterbirds belong to 7 orders and 10 families.Among the species surveyed,there is 1 species of Class Ⅰ protected birds in the List of National Key Protected Wild Animals and 11 species of Class Ⅱ protected birds.9 species included in Appendix Ⅱ of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES);listed as threatened (NT) near threatened by the Chinese Vertebrate Red List.There are 4 species of species;1 species are listed as endangered (EN).The composition of the bird flora in the reserve is dominated by Oriental species;in terms of types of residence,resident birds and winter migratory birds are dominant,followed by summer migratory birds and migratory birds.Among the habitats in Puzhehei,37 species of birds were recorded in wetlands,22 species were recorded in farmland orchard village habitats,41 species of birds were recorded in broad-leaved forest observations,16 species were recorded in coniferous forests,and 13 kinds were recorded in shrub observations.Generally speaking,Puzhehei has a rich diversity of birds,especially forest birds.The large amount of fruits and farming planted around them attract many birds to eat.Puzhehei's unique ecological environment provides a wintering habitat for many wintering birds.There are 33 species of waterbirds recorded in the reserve,belonging to 7 orders and 10 families;15 species of resident birds,18 species of overwintering waterbirds,and rich species.Zhehei provincial-level nature reserve resides and forms a stable population.Therefore,the protection of wetland habitats in Yunnan Puzhehei Provincial Nature Reserve,especially wetland aquatic plants is extremely important.
