7. Eastern Plains (EP)
7.2 South eastern Riverine Plains
The plains with dunes mostly occur east of Blackall Creek north of Stratford and east of the Perry River between Stratford and Bairnsdale. These sand hills and dunes form a discontinuous mantle over these plains and become more extensive east of Perry River. The sand dunes were most likely formed from sands blown from these streams by the prevailing westerly winds, particularly during periods of aridity associated with past glacial periods. The soils on the plains are similar to those on the older alluvial plains and terraces (Sodosols), with the soils on the dunes being deep, highly acidic sands, often with “coffee rock” in the subsoil (Podosols). Clays underlie these sands at a variable depth, except around Bengworden. Most of the original vegetation is now cleared for grazing, but some remnants of the former grassy woodland remain on the plains with areas of heathy woodland on the dunes. |
