Ragnar Hult
Ragnar Hult (1857–1899) 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.〔Trass, H. & N. Malmer, 1978. ''North European approaches to classification''. Pages 201-245 in R. H. Whittaker (ed.). Classification of plant communities. Dr. W. Junk Publ., den Haag.〕
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.〔Cowles, Henry C. (1911) The causes of vegetational cycles. Annals of the Association of American Geographers, 1 (1): 3-20 ()〕
