EVC/Bioregion Benchmark for Vegetation Quality Assessment Murray Fans bioregion EVC 103: Riverine Chenopod Woodland (syn. Black Box Chenopod Woodland) Description: Eucalypt woodland to 15 m tall with a diverse shrubby and grassy understorey occurring on most elevated riverine terraces. Confined to heavy clay soils on higher level terraces within or on the margins of riverine floodplains (or former floodplains), naturally subject to only extremely infrequent incidental shallow flooding from events if at all flooded.
