Introduction

The Huangshui River is the largest tributary of the upper reaches of the Yellow River and is located in the transitional zone between the Loess Plateau and the Qinghai-Tibet Plateau, with a drainage basin area accounting for 2.3% of the land area of Qinghai. The Huangshui River Basin is an important component of the ecosystem of the Qinghai Tibet Plateau with rich biodiversity (Wang et al. 2023, Hao et al. 2023). It contains mountains, wetlands, lakes and rivers that provide habitats for numerous species. The wetlands in the Huangshui River Basin have important water source conservation and biodiversity functions, with marsh wetlands and river wetlands being the main types of wetlands (Huang et al. 2023).

Plant diversity has important ecological significance in ecosystems and higher plant diversity can enhance ecosystem stability (Pohl et al. 2009, Mazzochini et al. 2019). Plant diversity also plays an important role in the restoration of degraded ecosystems and high diversity promotes rapid restoration and reconstruction of ecosystems after human-induced damage or natural disasters (Standish et al. 2021, Liu et al. 2021).

As a result of comprehensive investigations of plant resources in the Huangshui River Basin, species are constantly being updated. In addition to the original records of some vascular plant taxa in the Huangshui River Basin that were merged after the classification revision, more information needs to be updated. This article is based on nine books on plant species in Qinghai Province. In addition, we conducted two field investigations on vascular plant communities in Xining City, Haidong City, Haibei Tibetan Autonomous Prefecture and the Huangshui River Basin from the summers of 2021 and 2022, complemented by an extensive literature search and verification (Wang et al. 2023). We used the latest classification systems for various groups to revise and update the catalogue of vascular plants in the Huangshui River Basin and recorded information on species, sub-taxonomic groups and distribution areas. Based on the above information, we generated the latest checklist for wild vascular plants in the Huangshui River Basin.

This dataset can help researchers and environmental organisations to understand the plant diversity status of the Huangshui River Basin. By gaining insight into the types and distribution of plants, we can develop corresponding protection measures to prevent the extinction of endangered species and protect overall species diversity. This checklist facilitates the development of research and monitoring strategies and plays a crucial role in the protection and management of plant resources in the Huangshui River Basin.

Sampling methods

Sampling description: 

To generate the checklist, we used the following publications: "Wild Medicinal Plants in Qinghai" (Lu and Zhang 2012), "Atlas of Vascular Plants in Hainan Tibetan Autonomous Prefecture, Qinghai Province" (Volumes 1 and 2) (Zhou 2020), "Flora of Qinghai " (Volumes 1–4) (Liu 1997), "Atlas of Main Grassland Types and Common Plants in Qinghai" (Hou and Sun 2012) and "List of Seed Plants in Qinghai" (Gou 1990). In addition, in the summer seasons of 2021 and 2022, we conducted two field surveys to investigate the communities of herbaceous plant species in Xining City, Haidong City and Haiyan County of Haibei Tibetan Autonomous Prefecture, sampling a total of 455 quadrats comprising 4,113 records and 277 plant species (55 families and 172 genera). Based on this information, we calculated the diversity indices (species richness, Shannon-Wiener index, Pielou index and Simpson index) of the plant communities. These data were integrated into the aforementioned data to generate the final checklist. In addition, we used the iPlant (http://www.iplant.cn) and the Chinese Field Herbarium (http://www.cfh.ac.cn). These two websites are plant intelligence information systems and biodiversity information platforms built by the Institute of Botany, Chinese Academy of Sciences. iPlant focuses on the field of plant science and provides the latest research results in plant science. Chinese Field Herbarium can provide services such as species information enquiry, photo storage and species identification.

Quality control: 

The dataset consisted of 11 columns and could be divided into four parts: species information, geographic distribution information, data sources and national protection level. There were seven columns of species information, including Latin names for species, phyla, classes, orders, families, genera and nomenclature. The geographic distribution information, data sources and national protection levels each occupy one column (Appendix 1).

Step description: 

The dataset was organised as follows: (1) Deduplication of data. Based on the literature and field survey data, all data were integrated into the original checklist of vascular plants in the Huangshui River Basin, Qinghai Province and a table was generated. The information was checked using iPlant (http://www.iplant.cn), supplemented with the Chinese Field Herbarium (http://www.cfh.ac.cn). We combined the names of the orders, families, genera and species in the latest classification system, modified the Latin scientific names of the species in the table, removed duplicates and retained the unique order, family and genus information for relevance; (2) The classification system is updated. In this step, we redefined and systematically arranged the three major categories of ferns, gymnosperms and angiosperms according to the corresponding systems. Ferns were classified according to the system of lycopods and ferns; gymnosperms were classified according to the system of gymnosperms; and angiosperms were classified according to the system of angiosperms; (3) Organisation of geographic distribution. Based on the literature mentioned above, we have improved the geographical distribution of the various species. We also retrieved specimen records using iPlant (http://www.iplant.cn) and the Chinese Field Herbarium (http://www.cfh.ac.cn); (4) Indication of the national protection level. According to the “List of National Key Protected Wild Plants in China” released by the State Forestry and Grassland Administration, the species on the checklist were labelled with national protection levels.

Discussion

The Huangshui River Basin is an important ecological barrier in north-western China. Although it accounts for only 2.3% of the total area of Qinghai Province, it contains nearly 60% of the population, industry and agriculture in this Province. Based on remote sensing images, researchers evaluated the ecological environment of the Huangshui River Basin and concluded that its conditions were average (Zhao et al. 2018). However, as a result of global warming, the glaciers on the Qinghai-Tibet Plateau are retreating, which may affect the water resources in the Huangshui River Basin. Therefore, improving biodiversity can increase the stability of ecosystems in this region. For example, a higher plant diversity can reduce soil erosion, improve water quality and increase the sustainability of water sources. In this context, an updated checklist of the vascular plants in this region can improve our understanding of the distribution of local plant species, thereby facilitating the development of management and protection strategies. Based on our literature survey, there is no clear consensus amongst the scientific community regarding the types and distribution of vascular plants in the Huangshui River Basin, which necessitates the generation of a checklist. This checklist provides information about endangered or threatened plants in an area, thereby guiding government authorities in formulating relevant protection policies.

The Huangshui River Basin contains a variety of protected wild plant resources. Based on current knowledge, there are 38 species of national key-protected wild plants in 14 orders, 17 families and 22 genera. Many key protected wild plants in different countries are facing extinction, necessitating the implementation of suitable protection measures. Specialised wildlife and nature reserves can be established to create suitable habitats and protect the environment of endangered wild plants. In addition, it is necessary to strengthen habitat monitoring and population investigation of protected wild plants, providing the scientific basis for formulating protection measures. Education of the general public should be strengthened to raise awareness about the importance of national key protected wild plants.

Knowledge of the plant diversity of the Huangshui River Basin is crucial, as it improves our understanding of the current and future ecological environment and distribution of plant resources in this region. In this context, the checklist of vascular plant species provides a scientific basis for protecting the ecological environment, maintaining biodiversity and promoting sustainable development in this region. In addition, research on plant biodiversity can lead to the discovery of new plant resources and provide new research materials for fields such as agriculture, medicine and forestry.
