Japan has approximately 200 000 ha of mires (0.5% of the total land area), and peat reserves of ca. 625 million tons. Because of the great diversity in both climatic and topographic conditions various types of mire and wetlands are found. These range from the large coastal mires in Hokkaido to the mangrove forests with surrounding limnogenic mires in subtropical regions of the Ryukyu Archipelago. The majority of Japanese mires are, however, located in regions of recent volcanic activity and on the alluvial plains of Central Honshu and northwards. Most of the lowland mires have long since been reclaimed for rice culture or have partly been buried under built-up areas. In this paper, different forms of mire utilization are outlined and 30 legally (or otherwise) protected mires in Hokkaido are briefly described.

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
