Biodiversity Data Journal 11: e103497. https://doi.org/10.3897/BDJ.11.e€103497 Abstract Background Xinjizhou National Wetland Park is located in Jiangning District, Nanjing, Jiangsu, China. With diverse wetland landscape types, Xinjizhou National Wetland Park maintains high biodiversity all year around. Meanwhile, as an important hub on the East Asian- Australasian Flyway, Xinjizhou National Wetland Park also occupies a core ecological position in the middle and lower reaches of the Yangtze River in Jiangsu Province. Therefore, carrying out systematic bird surveys and consequently understanding the distribution of birds and the seasonal variation of their communities can provide important insights for conservation. We conducted a one-year bird survey in the Xinjizhou National Wetland Park from 2021 to 2022 and provided occurrence datasets, including detailed species and geographic information.This dataset fills the knowledge gap in avian community composition for the Wetland Park and more importantly provides a basis to assess the conservation effectiveness of conservation measures taken in the Wetland Park. © Shen W etal.

All data have been published on GBIF. Keywords Xinjizhou National Wetland Park, wetland, birds, dataset Introduction Wetlands have a crucial ecosystem function and play a key role in maintaining the survival and reproduction of many organisms (Zedler and Kercher 2005). Birds are rich in species, widely distributed and easy to observe, their population dynamics, community structure and diversity are often used as important indicators for wetland environmental dynamic monitoring (Bart 2005, Zhou et al. 2019, Wang et al. 2022). Wetland parks are important type of constructed wetlands. As a supplement to natural wetlands, wetland parks organically integrate wetland protection, ecological restoration and sustainable utilisation of wetland resources and play an increasingly important role in global ecological protection and sustainable development (Wu et al. 2015). Xinjizhou National Wetland Park is located in Jiangning District, Nanjing City. It lies in the upstream of the Jiangsu section of the Yangtze River, mainly including Xinji zhou, Xinsheng zhou, Zaisheng zhou, Zimu zhou and Zihui zhou. Xinjizhou National Wetland Park is an important representative of seasonally flooded wetlands in the middle and lower reaches of the Yangtze River. With diverse wetland landscape types, the Park maintains high biodiversity all the year round and, hence, is an important node for biodiversity conservation in the Basin (Wang et al. 2006, Cao et al. 2021). At the same time, as an important transit station in the East Asian-Australasian Flyway (EAAF), it also occupies an important ecological position in Jiangsu and even the middle and lower reaches of the Yangtze River (Yong et al. 2015). Therefore, carrying out systematic bird surveys and consequently understanding the distribution of birds and the seasonal variation of their communities can provide important insights for conservation of regional bird resources (Ellis et al. 2019, Chen et al. 2021). In this study, a systematic bird census was carried out monthly in Xinjizhou National Wetland Park from March 2021 to February 2022 to collate the bird distribution and community composition in the Wetland Park. Based on the annual monitoring results, the bird diversity and the seasonal variation of its community are analysed. The results can provide a scientific basis for the protection of bird diversity in Xinjizhou National Wetland Park and a detailed reference for the management and protection of beach wetlands in the middle and lower reaches of the Yangtze River. Occurrence dataset of birds in the Xinjizhou National Wetland Park, Nanjing, ... 3 Sampling methods Sampling description: A total of 10 survey transects were set up in Xinjizhou National Wetland Park according to the beach area, habitat types and accessibility. The length of the transect ranged from 1.0 to 3.3 km, covering all habitat types in the Wetland Park (Fig. 1). From March 2021 to February 2022, a monthly bird survey was carried out on each of the 10 lines with binoculars (Shuntu 339FT 10*42) and monoculars (Swarovski ATS 20*60), recording birds species and their abundances. For species which were difficult to identify in the field, we used a camera (Canon Eos R6) with telephoto lens (Sigma 150-600mm f/5-6.3 DG OS HSM C) to take pictures and identify them later in the lab. The classification of birds was based on A Checklist on the Classification and Distribution of the Birds of China (Third Edition) (Zheng 2017). The final dataset was organised according to the Darwin Core format and uploaded to GBIF upon the conclusion of annual survey (Shen et al. 2023).

All occurrence records are georeferenced. Due to the limitations of the sample line method, the positions of all recorded birds are replaced by lines' ID. 16 Column label eventID samplingProtocol samplingEffort sampleSizeValue sampleSizeUnit year eventDate eventTime country countryCode stateProvince locality locationID location decimalLatitude decimalLongitude geodeticDatum Shen W etal Column description An identifier for the set of information associated with an Event (something that occurs at a place and time). The names of, references to, or descriptions of the methods or protocols used during an Event. The amount of effort expended during an Event. Anumeric value for a measurement of the size (time duration, length, area or volume) of a sample in a sampling event. The unit of measurement of the size (time duration, length, area or volume) of a sample in a sampling event. The four-digit year in which the Event occurred, according to the Common Era Calendar. The date-time or interval during which an Event occurred. For occurrences, this is the date-time when the event was recorded. Not suitable for a time in a geological context. The time or interval during which an Event occurred. The name of the country or major administrative unit in which the Location occurs. The standard code for the country in which the Location occurs. The name of the next smaller administrative region than country (state, province, canton, department, region etc.) in which the Location occurs. The specific description of the place. An identifier for the set of location information (data associated with dcterms:Location). May be a global unique identifier or an identifier specific to the dataset. A Spatial region or named place. The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic centre of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive. The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic centre of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive. The ellipsoid, geodetic datum or spatial reference system (SRS) upon which the geographic coordinates given in decimalLatitude and decimalLongitude are based.

Leave the value empty if the uncertainty is unknown, cannot be estimated or is not applicable (because there are no coordinates). Zero is nota valid value for this term. The nature or genre of the resource. The name (or acronym) in use by the institution having ownership of the object(s) or information referred to in the record. A language of the resource. An identifier for the Occurrence (as opposed to a particular digital record of the occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the occurrencelD globally unique. The specific nature of the data record. The number of individuals present at the time of the Occurrence. Anumber or enumeration value for the quantity of organisms. The type of quantification system used for the quantity of organisms. A statement about the presence or absence of a Taxon at a Location. The full scientific name, with authorship and date information, if known. When forming part of an Identification, this should be the name in the lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term. The full scientific name of the kingdom in which the taxon is classified. The full scientific name of the phylum or division in which the taxon is classified. The full scientific name of the class in which the taxon is classified. The full scientific name of the order in which the taxon is classified. The full scientific name of the family in which the taxon is classified. The taxonomic rank of the most specific name in the scientificName. A person, group or organisation responsible for recording the original Occurrence. This research was supported by the National Natural Science Foundation of China (Grant No. 42271116).
