Cajander in the beginning of the century. It was based on vegetation, mire morphology, and landscape topography. The division was, however, difficult to compare with forest vegetation regions. As a result Prof. Aarno Kalela, in the 1950s, organized a study concerning the regionality of peat-land vegetation; the field work for which was performed by the authors as students. In this new division mire complex types and their regions were determined on the basis of vegetation but named according to mire morphology. The ecological approach to Finnish mire types also made it easier to compare them with peatland vegetation world-wide. Keywords: Historical review, mire complex types, Finland
