[Extract] The tropics of northern Australia, that is, areas north of the Tropic of Capricorn, are a climatically complex region dominated by summer rain deriving from monsoon related synoptic systems. Despite what might be expected, most of the area is arid; a substantial proportion is strongly seasonal (wet-dry) and only a small portion, principally those places geographically disposed to intercepting orographic rains brought by the southeast trades, can be considered perennially wet. Temperatures in most areas are high but outside the wet tropics, productivity of plant communities is restricted by seasonal drought and low nutrient soils, with high organic decomposition rates. Tropical Australia is, therefore, hardly an ideal setting for the development of peat dominated landscapes.Nonetheless, where conditions are right, peat accumulates and provides locally important windows into palaeoenvironments of the region. Many tropical peatlands in Australia are threatened by drainage works, reductions in groundwater pressure consequent on over-exploitation of artesian water supplies, increased rates of soil erosionand the exploitation of peat for commercial purposes. Their long term future in a "greenhouse" world is uncertain at best.
