This can be the 1st really ecosystem-oriented e-book on peatlands. It adopts an ecosystems method of knowing the world's boreal peatlands. the point of interest is on biogeochemical styles and methods, construction, decomposition, and peat accumulation, and it offers additional info on animal and fungal variety. A habitual subject is the legacy of boreal peatlands as awesome accumulators of carbon as peat over millennia.

Generally northward and inland, these coastal zones are followed by a zone of patterned bogs, with regional dominance of concentric and eccentric raised bogs (or basin bogs) especially dominant in more southern, subcontinental boreal areas such as southern Sweden and Finland, Atlantic Canada, Maine, and western (European) Russia. The patterned bogs are treeless or nearly so, dominated by species of Sphagnum (S. tenellum, S. capillifolium, S. austinii, and/or S. As climate becomes more continental, trees and/or shrubs become more abundant and water becomes less available at the bog surface; thus patterns are decreased.
A probable exception is the Hudson Bay Lowlands, where peat expansion took place rapidly after glacio-isostatic emergence (Kuhry 1998). According to Korhola and Tolonen (1996), most peatlands in Finland originated by primary peatland formation or paludification, although they caution that the percentage of terrestrialization (10 % or less) might be a significant underestimate. Paludification is also probably more widespread than terrestrialization in the boreal zone of western Siberia and in Quebec, (Walter 1977; Payette 2001b).
