Christian Theodor Vaupell (1821-1862) was a Danish botanist and forester. He was a student of Japetus Steenstrup and a teacher of botany at the University of Copenhagen to the young Eugen Warming[1].
Vaupell did macrofossil analysis of peat deposits and showed that in the Holocene development of temperate forest communities in Denmark, Betula was the chief early pioneer, followed by Pinus and Quercus and finally Fagus, which dominates today. These investigations pioneered the study of ecological succession[2].
