Plant diversity, flora and vegetation of Bat Dai Son Mountain area

The book provides data on plant diversity, flora, and vegetation of the Bat Dai Son Mountains and allied territories (Quan Ba District, Ha Giang Province, N Vietnam). Obtained data are based on fieldwork and laboratory studies of herbaria collected in 1995-2019 and available presently online. The monograph includes essays on the history of investigation of Bat Dai Son Nature Reserve, physical, hydrologic, climate, geology and geomorphology of the region, basic data on plant diversity and vegetation, descriptions of main plant communities and the flora, the plant key groups, and analysis of the threat for the plant diversity in the region. The documented and illustrated annotated list of studied plants includes 1146 species belonging to 521 genera and 162 families. Among studied plants, 1 family, 11 genera, and 169 taxa are expectedly new for the flora of Vietnam, 27 taxa are new for science. The total number of plants in studied flora may be estimated as 3500-4000 aboriginal and invasive species. This is a significant center of local regional plant diversity and the refuge of many strictly endemic forms of life.
