Abstract

Abstract: Guizhou Province is located in the hinterland of southwestern China and the eastern part of the Yunnan-Guizhou Plateau, with a unique ecological position and rich biodiversity. Its vascular plant species diversity ranks fourth in China. Based on the Flora of Guizhou, related literature, and specialized surveys, this study systematically compiled data on the diversity of vascular plants in Guizhou, covering information such as species names, distribution, and conservation status. Statistics were conducted according to administrative divisions and natural geographic regions, including the four major mountain ranges and eight major river systems of the province. As of April 30, 2025, a total of 11,686 species and infraspecific taxa (including 9,921 species and 1,765 infraspecific taxa) of vascular plants have been recorded in the province, belonging to 386 families and 2,396 genera. Among these, there are 10,967 species of wild vascular plants in 373 families and 2,185 genera, 548 endemic vascular plant species in Guizhou, 781 karst-obligate plant species, 719 commonly introduced and cultivated plant species in 115 families and 402 genera, and 202 invasive vascular plant species. The dataset also records 256 nationally key protected wild vascular plant species and 55 provincially key protected wild vascular plant species in Guizhou. In terms of spatial distribution, Qiannan Buyi and Miao Autonomous Prefecture (6,790 species) and Libo County (3,981 species) have the highest species richness among prefecture-level and county-level units, respectively. The Miaoling Mountains (6,340 species) and the Wujiang River System (8,732 species) are the regions with the highest species diversity among mountain ranges and river systems, respectively. These results provide important data for understanding the characteristics of vascular plant diversity in Guizhou and for their conservation and utilization. They also offer the latest data support for the compilation of specialized works such as the Flora of Guizhou (second edition) and the Dendrology of Guizhou.
