The Collegium Palynologicum Scandinavicum (CPS) was established in 1969 by Professor Gunnar Erdtman and a group of Nordic palynologists with the aim to stimulate the interest for palynology and to coordinate palynological research in the Nordic countries.
The Collegium Palynologicum Scandinavicum as well as GRANA have roots in quaternary to recent palynology, which flourished in the Nordic countries in the forties to fifties. The activities of the CPS ceased in the sixties, while GRANA continued to flourish.
In 1970-1980, many creative palynologists found activities within geology and the expansive oil-prospection work in the Nordic countries. After a few passive years, a new need for society contacts led to the re-activation of the CPS.
The coordination and regular holding of Nordic Palynological Meetings now became an activity, which contributed to bringing a new generation of palynologists together in the society as well as socially. There are now some 140 members in the five Nordic countries. The society grows steadily and GRANA is a well renowned and spread out Journal of Palynology and Aerobiology.
