Main vegetation type: Acacia Iysiphloia/Eucalyptus terminalis mid-high open-woodland with hummock/tussock grassland understorey. Great Soil Group: Siliceous sands Land units with similar vegetation: 4d Communities contained within this Land unit (from site data): 62 Land unit 6a1 Area: 59 km2 Main geology: Qa,Qt,Czs Distribution: Found on low lying alluvial plains, near main river systems. Slopes are generally negligible although dissected areas and gilgais occur. Soils V!!ry from cracking black clays to siliceous sands. The Eucalyptus microtheca communities occur along low lying river levees, adjacent to river banks and in depressions. Soils are medium black cracking clays. The tussock grassland communities occur on floodouts and plains, generally adjacent to the Eucalyptus microtheca communities. The Melaleuca communities generally occur on the periphery of the flood out areas were soils are more sandy or along drainage depressions on smaller river flats and creeks further inland from the major river systems. Main vegetation type: Eucalyptus microtheca mid-high woodland to tall open-forest/tussock grassland with scattered trees/M.viridifolia-M.minutifolia mid-high woodland. Great Soil Group: Alluvial soil, black earths, earthy sands, grey and red clays Land units with similar vegetation: 6a2,5a _ Associated vegetation types: Eucalyptus pruinosa mid-high woodland occurs in some areas (similar to land unit 5a). Melaleuca leucadendra tall open-forests occur along the river-banks in some regions. Eucalyptus papuana and Eucalyg.lus terminalis tall open-woodland to tussock grassland can occur along high sandier river levees. . Communities contained within this Land unit (from site data): 1,3,9,12,20,21,22,23,59,68 Land unit 6a2 Area: 770 km2 Main geology: Czs/Qa Distribution: This community occurs on alluvial plains, forming the valley floors and flats between the plateaux. Slopes are generally between 1 and 2 degrees. Residual dolomitic rock outcrops occur. SOils are siliceous sands or Iithosols (10-600cm). Main vegetation type: Eucalyptus tectifica/Eucalyptus terminalis mid-high open-woodland to mid-high woodland with tall tussock grassland understorey. Great Soil Group: LithOsols, grey, red and yellow earths Land units with Similar vegetation: 6a 1 12 .... _ . R_.--;.. .' , .), ,.r: 'if ~,'
