摘要：

Soundly-based conservation plans for Anatidae require abundance and distributional data to provide accurate estimation of population sizes and trends and to identify key sites for protection. Here, we report the first ever extensive surveys throughout eastern China's wetlands for Anatidae, 80% of which occurred in the Yangtze floodplain. Population estimates for 24 species with sufficient data are provided, allowing assessment of the accuracy of current flyway population estimates; fourteen species are far less numerous than previously believed and three far more numerous. Further improvement of the population estimates for eastern China will need coordinated counts across the region requiring a large, skilled counter network. (C) 2008 Elsevier Ltd.
