Regional variation and conservation of mire ecosystems

This volume contains papers based on lectures and posters presented at the 6thfield symposium of the International Mire Conservation Group, held in Norwayin 1994. The 24 contributions plus an introduction deal with variations in thevegetation, flora, hydrology, hydromorphology, distribution and conservation ofmires as well as factors threatening them. For instance: regional differences(worldwide) in the water chemistry of bogs, and implications for vegetation classification; regional variation in boreal mire ecosystems in Canada through time;comparisons of boreal mire ecosystems in western Europe and eastern NorthAmerica; work on a small-scale mire vegetation map of Europe; methods forsmall-scale mapping of mire complexes in Russia; hydrology and restoration ofraised bogs after peat-cutting in Austria and Ireland; restoration of mires drainedfor forestry in Finland; Ellenberg's indicator values for temperature and continentalityfor mire plants used in regional studies in Norway. A number of papers dealwith descriptions of mire ecosystems and the conservation situation in variouscountries: Estonia, Poland, Ukraine, the Fennoscandian countries, Canada, Lesotho(rare and threatened types of soligenous fens with flarks) and Japan. Paperson criteria for protection of mires, a survey of the international peat trade; comments on IMCG work, as well as the Trondheim Declaration and the 18 nationalresolutions are also included
