Ragnar Hult

Ragnar Hult (4 March 1857 – 25 September 1899) was a Finnish botanist and plant geographer. He was a forerunner in developing a methodology for vegetation survey. He emphasized the physiognomy of vegetation and paid less attention to its ecology. His ideas were much-followed in Sweden, making him the real father of the "Uppsala school" in plant sociology.

Ragnar Hult was the first (1881) to publish a comprehensive study of ecological succession as it is taking place in a given region. He was the first to recognize that a relatively large number of pioneer plant communities give way to a comparatively small number of relatively stable communities.
