(a) Soil podzolization across natural landscapes and (b) across reconstructed landscapes. In this schema (above) from Thompson (1992), a greater natural distribution of 'desired' mixed-Eucalypts is found among inland high-dunes which have an increasing A1, A2 and B horizon. Black scheoak (among other pioneer species) are more highly distributed in fore-dunes which have a younger status of pedogenesis. Meanwhile, the pedogenic status of reconstructed podzol soils from Menzies and Shan-Teys (2000) is shown (below) to increase with greater weathering patterns.
