A Sampling-event Dataset from Aerial Surveys of Northern Eurasian Waterbirds, 2014–2024 - Version 1.4

qszhao@rcees.ac.cn (Zhao Qingshan) — Wed, 08 Apr 2026 08:30:09 +0800

We present a comprehensive, decade-long (2014–2024) aerial survey dataset of northern Eurasian waterbirds, covering a broad northern Eurasian study area, with survey effort concentrated in the Russian Arctic and Subarctic. Surveys in a purpose-built light hydroplane covered 1,140,337 km of flight tracks across 67 administrative districts and a net, non-overlapping area of 1,918,845 km² (45.20–76.52°N, 35.49°E–180.00°E / 180.00°W–172.05°W). The dataset contains 97,638 georeferenced occurrence records, comprising 2 distinct survey components: marine (14%) and inland basin (86%) surveys. The 10 most abundant species (4 geese and 6 ducks) account for 76% of all individuals. Following spatial deduplication with survey-type grouping, the dataset encompasses 2,438,521 deduplicated individuals from 42 species in 19 genera, distributed as: marine surveys: 397,373 individuals (16%) from 34 species; basin surveys: 2,041,148 individuals (84%) from 42 species. These records provide a spatially explicit baseline for analyses of broad distribution patterns and conservation planning in surveyed regions of northern Eurasia.

wumengling200211@163.com (Mengling Wu) — Mon, 30 Mar 2026 08:58:38 +0800

This study synthesizes line monitoring data collected from multiple locations within Gansu Province, including Subei Mongolian Autonomous County, Yumen City, Lanzhou City, Luqu County, and Wudu District of Longnan City, spanning the years 2011 to 2020. Additionally, it incorporates line records from Tianzhu County (2014–2020), as well as Gaotai County, Minqin County, Maiji District of Tianshui City, Kongtong District of Pingliang City, Wen County, and Dunhuang City (2016–2018). Drawing upon these asynchronous surveys conducted across varying temporal and spatial scales, a comprehensive sampling event dataset was developed, comprising 118 transects and encompassing 373 species. The dataset includes 27,077 georeferenced event records, representing 157,345 individual organisms from 373 species distributed across 21 orders, 65 families and 191 genera. The most abundant species was the Sparrow, constituting 12.57% of all individuals, followed by the Bar-headed Goose, which accounted for 10.43%. All records adhere to Darwin Core standards, thereby providing a robust foundation for subsequent analyses of population trends, habitat associations, and inter-basin comparisons within Gansu Province.

A Sampling-event Dataset from the Survey of Wintering Waterbirds in Coastal Fujian Province, China - Version 1.1

qszhao@rcees.ac.cn (Zhao Qingshan) — Mon, 23 Mar 2026 16:40:51 +0800

We present a sampling-event dataset from a synchronised survey of wintering waterbirds conducted across coastal wetlands in Fujian Province, China, in February 2006. The survey aimed to systematically assess regional distribution patterns and abundance of waterbirds. The geographical extent ranged from 23°43′N to 27°17′N and from 117°19′E to 120°18′E, covering 2,657.56 km². Systematic observations were carried out at 191 fixed survey points across 21 wetlands, including 25 wetland nature reserves. The dataset contains 108,125 recorded individuals of 64 waterbird species in 40 genera. The 10 most abundant species account for 84% of all individuals, comprising 4 shorebirds, 3 ducks, 1 gull, 1 egret and 1 cormorant. Records are organised according to Darwin Core standards as sampling events with linked occurrence records, ensuring comparability and reusability. This dataset provides a spatially explicit baseline for analyses of wintering waterbird distributions, long-term monitoring of population dynamics, and conservation planning for coastal wetlands in Fujian.
