Peatland Forestry: Ecology and Principles (Ecological Studies) Hardcover - 1995 - 1995th Edition

From the publisher

Peatlands (or mires) cover at least 550 million ha globally, of which the greater part is situated between 50 and 70 N. Although the majority of peatlands are not used for human needs, there are large areas where agriculture, peat or wood production has been practiced. The suitability of peatlands for forestry differs from country to country depending on climatic conditions, raw wood demand, silvicultural management practice and tradition, as weH as the infrastructure in the remote areas considered. Peatland utilization for forestry may be divided into three efficiency catego- ries: (1) exploitation (harvesting oftrees with inadequate attention to regenera- tion) leading to reduction in the renewable resouree; (2) silvicultural manage- ment (harvesting of trees with natural or artificial regeneration) aimed at main- taining the renewable resource in a sustainable way; and (3) progressive rorest management (drainage, fertilization, afforestation, thinning, ditch maintenance, final harvest and regeneration) aimed at increasing the renewable resource. In North America, forestry utilization is changing from exploitation towards a kind of silvicultural management whereas progressive forest amelioration activities on forested peatlands and waterlogged mineral soils are part of the normal forestry practiees in Fennoscandinavia, the Baltic countries and Russia. In the British Isles afforestation of open peatlands is associated with drainage. This monograph is a review and synthesis of peatland forestry on northern peatland (mire) ecosystems. It covers peat soH properties, mire hydrology, car- bon and nutrient cycling, and classification of mire sites.
