1 Introduction

Biodiversity monitoring provides information on the spatial and temporal changes in biodiversity. Biodiversity has become one of the most important indicators when evaluating the effectiveness of ecological protection[1]. Birds are one of the most important top consumers in wetland ecosystems, and are unlikely to be completely isolated from other low-nutrition organisms and inorganic environments[2]. Waterbirds are a higher biota endemic to wetlands, and form an important component in wetland ecosystems; waterbirds are also an indicator species used to characterize changes in wetland quality[3,4]. Waterbird monitoring involves monitoring their numbers, behavior, habitat, and other information, according to the previously arranged space and time plan[5,6].

A relatively independent closed basin, the Qinghai Lake basin is located on the eastern edge of the Qinghai-Tibet Plateau, and is a hub connecting the eastern and western Qinghai province and southern Qinghai region. The Qinghai Lake basin forms a very important part of the ecological security barrier of the Qinghai-Tibet Plateau and plays an important role in blocking the spread of western desert to the east[7,8]. The Qinghai Lake National Nature Reserve is located at the intersection of two migratory paths in Central Asia and East Asia, and its wetland area ranks first in China[9]. This dataset constitutes a waterbird monitoring sample point of the Qinghai Lake National Nature Reserve Administration over the years[10]. The monitoring period was from March 2018 to February 2019, and waterfowl monitoring was carried out nine times throughout the year. Through waterbird monitoring, the waterbird population, population dynamics, population distribution, and population structure were obtained. The waterbird monitoring data were sorted out and to construct the 2018 waterbird monitoring dataset of the Qinghai Lake basin.

2 Metadata of the Dataset

The metadata of the Waterfowl habitat and migration dataset collecting from 30 sample sites in Qinghai Lake basin (2018)[11] is summarized in Table 1. It includes the dataset full name, short name, authors, year of the dataset, data format, data size, data files, data publisher, and data sharing policy, etc.

3. Data Development Methods

Waterbird monitoring involves numbering the original monitoring sites and points, and standardizing named plots and place names according to the associated administrative division. It also involves determining 10 habitat types, and unifying the collection record of interference type and interference intensity information. According to the characteristics of waterfowl distribution in Qinghai Lake, 24 waterbird monitoring samples were set up in the area around Qinghai Lake. These 24 monitoring samples were composed of 30 monitoring sample points (Figure 1).

In 2018, the place names of the waterbird monitoring sample sites and sample sites were sorted out and standardized according to the administrative areas, and all the monitoring sample sites were uniformly numbered. Among them, there are three sample sites: Reed Lake, Sun Lake, Yuya Lake, Ganzi River Wetland, grass bag, Ganzi Estuary, Orchid Lake, Buha River samples, Buha River Bay, and Buha River Estuary. According to the spatial and temporal distribution characteristics of Qinghai Lake, the habitat types of the monitoring samples (the habitats of waterbirds), the waterbird migratory residence places, the non-cluster breeding grounds, the wintering grounds, the foraging grounds, the cluster breeding camp nest ground five categories. The habitat types are divided into 10 different types: estuarine wetland, marsh meadow, farmland, sub-lake, freshwater lake, river wetland,

In 2018, the habitat interference degree of waterbirds was the Heimahe river wetland, Daotanghe wetland, Erhai, Quanwan wetland and Jiangxigou. The main interference types were tourism, bird watching, and road traffic. Field surveillance was shown in Figure 2. Important waterbird habitats not included in the protection area are Daotanghe wetland, Hadatan, and Jiangxigou. In 2018, the annual cumulative number of waterbirds in Qinghai Lake was 251,000, nearly 20,000 fewer compared with 2017. The total population of waterbirds in Qinghai Lake between 250,000 was between 250,000 and 360,000 and 2018 (Table 4).

The 57,000 waterbirds recorded in late October 2018 was the highest peak of the year. During spring migration, waterbirds have 10 key habitats (Figure 3), namely Ganzi river wetland, Hadatan, Naren wetland, Cormorant island, Egg island, Erhai, the Shaliuhe river estuaries, Paerqiong wetland, Quanwan wetland, and Jiangxigou. The dominant species are the great cormorant, Phalacrocorax carbo; the coot, Fulica atra; the bar-headed goose, Anser indicus; the ruddy shelduck, Tadorna ferruginea; the tufted duck, Aythya fuligula; the common pochard, Aythya ferina; and the brown-headed gull, Larus brunnicephalus.

5 Discussion and Summary

During the 2018 summer breeding and autumn migration periods, due to the inaccessibility to people and vehicles, the Buha river estuary, Wuhaalanqu estuaries, Paerqiong wetland, and the Qiejihe river estuaries led to incomplete monitoring sample site records. Due to the 2017 brown-headed gull, Larus brunnicephalus, camp site (Cormorant island), the camp nest conditions were lost. No new brown-headed gull, Larus brunnicephalus, camp site was found during monitoring, and only a few nest areas were found in the bird island area. The brown-headed gull, Larus brunnicephalus, breeding status was not recorded. As Qinghai Lake waters rising wetland environment change, since 2016 appeared several new waterbird habitat and waterbirds distribution is more concentrated location, Naishiji Wetland (the old Hong Lake), Haergai river estuaries, Ganzi river wetland, Erlangjian, Zhegeli Wetland, Nuraogeta Estuary, the above sites in 2018 but was not formally included in the sample point monitoring, so waterbird habitat monitoring is not comprehensive. Monitoring equipment and means is not adapted to the current needs of waterbird monitoring, such as some personnel and vehicles in an inaccessible habitat without effective means to conduct monitoring work. Although efforts have been made to standardize the monitoring of waterbirds, due to human factors, there is no unified and efficient field patrol system.

In view of the drastic decline in waterbird populations, further strengthen the patrol monitoring work real-time grasp of waterbird dynamic changes and distribution, actively implement the wetland protection and restoration project and reserve overall planning of ecological restoration and ecological restoration project, make the overall population of Qinghai Lake waterbirds stable. It is necessary to actively respond to the adverse effects of waterbird nesting habitats due to changing ecological environments, and to restore waterbird nesting habitats for cluster breeding waterbirds. Qinghai Lake wintering waterbirds has formed from the original swan as the main advantage species to latent duck and Ruddy Shelduck Tadorna ferruginea as the advantage of the original wintering ground (Quanwan wetland, Qiejihe river estuaries, Niaodao) to strengthen patrol monitoring, the new wintering ground (Jiangxigou) wintering birds foraging land award measures, retain the wintering and migratory waterbirds guarantee the population of Qinghai Lake wintering birds. Law enforcement should be strengthened to reduce the interference of no activities within a specific period of time, to create a safe and quiet habitat for waterbirds. For waterbird habitats not situated in protected areas, negotiations with local government should be conducted to establish a ??community watch?? or jointly carry out joint prevention and management with the community.
