Lateritic Podzolics (shallow Claravale). Woodland dominated often exclusively by E. bleeseri with Petalostigma quadiloculare and very poor Plectrachne pungens dominated pastures. Very shallow, gravelly and drought affected soils; subject to high amounts of sheetwash and very erodible if disturbed. Claravale and Woggaman. Ei ther valley floors in sandy country; lines or backplains. or low-lying seepage areas frequently abutt drainage Siliceous Sands (Stray), alluvial Red Earths (Umbrawarra) and Yellow Podzolics (Douglas), the latter on flattest areas. Scattered tall E. polycarpa with extensive open treeless areas. In drainage floors dense Melaleuca sp. and Grevillea pteridifolia scrub. In the outwash areas scattered G. pteridifolia and Verticordia cunninghamii, short annual grasses and low sedges. Very wet and untrafficable in the wet season; highly erodible if disturbed. Mainly Jindara; minor Occurrence in Tagoman and Woggaman. Undulating terrain; 3%. slopes generally less than Rather variable but typically Lateritic Podzolics (Jindare) and Yellow Podzolics (Ejong); frequent pig wallows. Rather open woodland with a wide range of species; scattered shrubs (Grevillea heliosperma, Petalostigma sp.); pastures dominated by annual Sorghum sp. with some perennials. 48
