The Huai He floodplain in Anhui and Jiangsu Provinces, an important component of the East Asian-Australasian Flyway (EAAF), sustains critical wetland habitats for migratory waterbirds, including four threatened species on the IUCN Red List: critically endangered (Radde, 1863), endangered (Linnaeus, 1758) and vulnerable (Linnaeus, 1758) and (Linnaeus, 1758). Despite its biogeographic significance as a transitional zone between the Yangtze and Yellow River floodplains, this region remains one of China's most understudied and ecologically degraded freshwater systems. Historical pollution events and contemporary anthropogenic pressures - agricultural intensification, hydrological fragmentation and invasive species - have severely compromised wetland integrity. During mid-December 2005 and November to December 2006, standardised surveys employed fixed-radius point counts (158 sites) with the component counting method to enhance accuracy.
We present the first comprehensive waterbird dataset for the Anhui and Jiangsu part of the Huai He floodplain, comprising 44 species (32,517 individuals) recorded across 30 wetlands during 2005-2006 surveys. All occurrence data adhere to Darwin Core standards and are accessible via the Global Biodiversity Information Facility, providing spatial-temporal baselines for abundance and distributional data for waterbirds in this region.
安徽和江苏省的淮河泛滥平原是东亚-澳大利西亚迁徙路线（EAAF）的重要组成部分，为迁徙水鸟提供了关键的湿地栖息地，其中包括国际自然保护联盟红色名录上的四种濒危物种：极危（红胸黑雁，1863年）、濒危（鸿雁，1758年）、易危（豆雁，1758年）和（白额雁，1758年）。尽管该地区作为长江和黄河泛滥平原之间的过渡地带具有生物地理意义，但它仍是中国研究最少、生态退化最严重的淡水系统之一。历史污染事件和当代人为压力——农业集约化、水文破碎化和入侵物种——严重损害了湿地的完整性。在2005年12月中旬以及2006年11月至12月期间，采用固定半径点计数法（158个地点）和组分计数法进行标准化调查，以提高准确性。
我们提供了淮河泛滥平原安徽和江苏部分地区首个全面的水鸟数据集，包括2005 - 2006年调查期间在30个湿地记录的44种（32517只个体）水鸟。所有出现数据均符合达尔文核心标准，可通过全球生物多样性信息设施获取，为该地区水鸟的数量和分布数据提供了时空基线。
