Characterising soil physical properties of selected Temperate Highland Peat Swamps on Sandstone in the Sydney Basin Bioregion

Sydney Basin, New South Wales, Australia. Some of Temperate Highland Peat Swamps on Sandstone Basin overlie existing underground mining areas, which may impact the hydrological fluxes into and out swamps. Understanding predicting these potential impacts their consequences for swamps’ vegetation requires knowledge relevant physical properties soil, however such is almost completely absent from literature. This study addresses this gap, provides new insight degree nature variability between swamp sites, groups swamps, soil controlling variabilities classification swamps in context peatland. Soil samples were collected up to a depth 750 mm ten sites Upper Nepean Newnes Plateau Samples analysed organic matter, bulk density, texture, saturated hydraulic conductivity water retention characteristics. Not only but also density sand content control vary swamps; however, not large relative those found peatlands globally. These THPSS cannot be classified as peatland so parameters estimated through generalisation properties. It concluded that insights provide scope developing models assist ecological analysis
