Ragnar Hult

Ragnar Hult (4 March 1857 – 25 September 1899) was a Finnish botanist and plant geographer.

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.

[1] Ragnar Hult was the first (1881) to publish a comprehensive study of ecological succession as it is taking place in a given region.

Swamps proceed from moss to sedges to moor vegetation followed by birch and finally spruce.
