      ‘This is a major new contribution to the study of salt marshes and mangrove forests. Uniquely comprehensive, the book provides extraordinary coverage of coastal wetlands from the Arctic to the tropics with superb case study examples from Africa, Europe, Asia, and both Non peat-forming wetlands (marshes, swamps) lack the well developed bryophyte ground layer of the fens and bogs, and are subject to severe seasonal water level fluctuations. The Canadian Wetland Classification System has been successfully used in Arctic,

    The CWCS is based on the adoption of a three-level classification: (a) five wetland classes (bog, fen, swamp, marsh, and shallow waters), (b) wetland forms based on surface morphology, surface pattern, water type, and underlying soil morphology, and (c) an open-ended number of wetland types based on physiognomic characteristics of vegetation communities (Fig. 1).

Wetlands are most likely the largest natural source of methane to the atmosphere accounting for ~20% of the current global annual emission of ~– Tg (10 12 g) (Khalil and Rasmussen, ; Cicerone and Oremland, ; Fung et al., ; Crutzen, ; Houghton et al., ). Measurements of methane from Greenland and Antarctic ice cores indicate atmospheric concentrations of Africa has long been regarded as the cradle of humankind, but scientists seeking a more specific location have narrowed in on northern Botswana as the 'homeland' for all modern humans, according.
