Warming's influence on later Scandinavian ecology was immense. Especially significant was his inspiration to Christen Raunkiær – his pupil and successor on the chair of botany at the University of Copenhagen. In addition, he had a direct influence on Danish research, scientific and other, for a couple of decades. After his appointment to the professorship in Copenhagen, he gradually took over Japetus Steenstrups power base, most notably as one of three members of the board of the Carlsberg Foundation for 32 years. Thus, Warming had the upper hand in who should be granted money and who should not.
