The results of inventories of drained peatlands have occasioned criticism of profitless drainage. For the better understanding of the mire ecosystem a functional and structural division of mires is presented. This is based on the nutrient cycle, the mire margin — mire expanse-effect, the carbon balance and the community structure of mire sites. The suitability for drainage is discussed on the basis of the ecology. A suggestion is made for further treatment of drained mire complexes.

Controversy between the conservation and utilization of Scottish peadands is discussed on the basis of the authors' experience from the excursion of the International Mire Conservation Group (IMCG) to Scotland in September 1986 (EK & PS) and the participation in the international symposium "Peatland Ecosystems and Man: An Impact Assessment" in Dundee, Scotland in September 1989 (HV). Many blanket mires, especially in north-central Scotland, have an international conservation value. At the same time almost one fifth of this mire area has been afforested. The purpose of the Nature Conservancy Council is to conserve as large watershed areas as possible and to guide afforestation to those areas which have already lost their naturalness. There is now an urgent need of mire conservation in Scotland in order to save distinguished areas of Scottish blanket mires.
Key words: afforestation, peatlands, preservation, Scodand
