Abstract

BackgroundWe describe a dataset providing information on the geographic distribution of northern Asian endemic alpine plants. It was obtained by digitising maps from the atlas “Endemic alpine plants of Northern Asia”. Northern Asia includes numerous mountain ranges which may have served as refugia during the Pleistocene ice ages, but there have been no studies that analysed this question. We suggest that this dataset can be applied for better understanding of the alpine endemism in northern Asia.New informationThe dataset includes 13709 species distribution records, representing 211 species from 31 families and 106 genera. Each record provides data regarding the distribution of an individual species. These data provide a foundation for studying northern Asia's endemic alpine species and conducting research on the factors concerning their distribution.

Highlights

  • Being climatically and topographically heterogeneous, mountain ecosystems are characterised by a high degree of plant species diversity (López-Pujol et al 2011, Hassan et al 2005)

  • During the Pleistocene glacial periods, ice sheets expanded greatly throughout northern Asia, mountainous regions contributed to the preservation of a number of alpine species (Harrison and Noss 2017, Volkova and Baranova 1980)

  • Malyshev considered nine mountain areas in northern Asia that served as refugia during ice ages of Pleistocene for at least 231 alpine endemic species (Malyshev 1979, Vodopyanova et al 1974)
