In this study, these data are statistically analysed to find and identify relations between changes in botanical biodiversity and changes in climate and other environmental factors. Prior to the analysis, the data have been corrected for several major forms of survey bias. The records are grouped into three intervals covering the 20th century: 1902–1949, 1975–1984, and 1985–1999.
