Abstract

Abstract: Based on long-term fixed-point observation data, the long-term dynamics of the waterbird community since the establishment of the Chenhu Wetland Nature Reserve were analyzed. It was found that the number of species and individuals in the Chenhu wetland waterbird community increased significantly from 2005 to 2021, with a fluctuating increase in species diversity indices. Winter migratory birds constituted the majority of the community, with waders predominating in terms of species count and swimming birds in terms of individual count. The species count of omnivorous waterbirds was dominant, and the composition of individual count had shifted from having no clear dominant type to a predominance of herbivores. The Anseriformes and Charadriiformes were the dominant orders in the waterbird community. The number of dominant species in the waterbird community gradually decreased after 2015. The waterbird community underwent two stages: a period of significant changes in species composition and a period of minor changes in species composition. Endangered and rare waterbird species were observed annually in Chenhu Wetland from 2005 to 2021. After 2017, the number of endangered and rare waterbird species began to steadily increase, and unique waterbird species were observed annually after 2018.
