Aim: In order to comprehensively understand the current status of wild vascular plant resources and to provide the basic information for the conservation of plant diversity, it is necessary to compile, improve and update the checklist of Qinghai plants.

Method: Based on the existing historical data, we comprehensively collected relevant literature on plant research in Qinghai Province, combined data from years of field surveys and specimen information, and compiled a checklist of wild vascular plants. 85.01% of the species are accompanied by voucher specimens (including collector, specimen collection number, and barcode number), provenance, habitat, and distribution information of each species and infraspecies.

Results: There were 2,916 species (including subspecies) of wild vascular plants in 109 families and 602 genera in Qinghai Province, including 55 species from 12 families and 20 genera of lycophytes and ferns; 36 species from 3 families and 6 genera of gymnosperms; 2,825 species from 94 families and 576 genera of angiosperms, with 500 species added compared with the Index Florae Qinghaiensis. The results showed that the top 10 dominant families of wild vascular plants in Qinghai Province were Asteraceae (346 species), Poaceae (343 species), Fabaceae (222 species), Ranunculaceae (160 species), Rosaceae (146 species), Brassicaceae (113 species), Orobanchaceae (96 species), Gentianaceae (90 species), Cyperaceae (86 species), and Caryophyllaceae (84 species), which were comprised of 1,686 species, accounting for 57.82% of the wild vascular plants in Qinghai Province. The top 5 dominant genera were Astragalus (95 species), Pedicularis (83 species), Saussurea (76 species), Artemisia (66 species), and Carex (65 species). The composition of families is dominated by families with less than 20 species, and the composition of genera is dominated by genera with less than 5 species. Meanwhile, the checklist contained a total of 47 species of national key protected wild plants, belonging to 17 families and 25 genera, all of which were under the second level of protection.

Conclusion: The checklist can provide basic data for field survey and monitoring, collection and preservation of germplasm resources and biodiversity conservation.
