The species data were obtained from the Chinese Vascular Plant Distribution Database. The database has been assembled over the last 10 years by the Biodiversity and Biosafety Group at the Institute of Botany, Chinese Academy of Sciences. The database consists of native species occurrence records collected in the period 1900 – present time, with the majority of collections made after 1950, from both museum inventory reports and published literature such as floras and checklists at a national, provincial, and regional level (Huang et al., 2011). Standardization of taxonomic names in the database was done according to Catalogue of Life China (Checklist 2015, http://www.sp2000.org.cn/) and Flora of China (http://foc.eflora.cn/).
For this study, only gymnosperm species were considered and the dataset used here contains 243 species at species and sub-species level (covering all Chinese gymnosperms). Species occurrences are represented at the county level (2380 counties), and each occurrence is considered a presence.
The excell sheet contains presence data for all gymnosperm species in China. Ones in the dataset indicate a species presence. Zeros in the dataset do not indicate true presences. Presences are recorded for all chinese counties, and each of these counties is represented by a county code ('CNTY_CODE'). Each county is likewise associated by the point location of the county centroid in WGS84 latitude and longitude coordinates (columns 'Lon' and 'Lat').
