EVC/Bioregion Benchmark for Vegetation Quality Assessment Lowan Mallee 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 major events if at all flooded.

EVC/Bioregion Benchmark for Vegetation Quality Assessment Lowan Mallee bioregion EVC 641: Riparian Woodland Description: Occurs beside permanent streams, typically on narrow alluvial deposits. Woodland to 15 m tall generally dominated by Eucalyptus camaldulensis over a tussock grass-dominated understorey. Tall shrubs may be present and amphibious herbs may occur in occasional ponds and beside creeks. While flooding may be common, sites are rarely inundated for lengthy periods.
