From pre-christian times peatland-use and attitudes towards peatlands in Germany have changed to a great extent. Agricultural use of the inhospitable peat bog terrain only developed after the fertile soil regions had been conquered in the so-called struggle for food production. Use for fuel production never reached the amount of peatland used for agriculture, and with the use of peat as a horticultural ameliorator at the beginning of this century, only a small portion of the peat area has been touched and is not larger than the area under nature conservation. With these changes, attitudes about the associated environmental impact have shifted enormously at the same time.
Key words: Agriculture, historical review, horticulture, mire utilization

The first regional division of Finnish peatlands was purposed by A.K. 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.
