EVC/Bioregion Benchmark for Vegetation Quality Assessment Victorian Riverina bioregion EVC 56: Floodplain Riparian Woodland Description: An open eucalypt woodland or open forest to 20 m tall over a medium to tall shrub layer with a ground layer consisting of amphibious and aquatic herbs and sedges. Occurs along the banks and floodplains of the larger meandering rivers and major creeks, often in conjunction with one or more floodplain wetland communities. Elevation and rainfall are relatively low and soils are fertile alluviums subject to periodic flooding and inundation.

EVC/Bioregion Benchmark for Vegetation Quality Assessment Victorian Riverina bioregion EVC 61: Box Ironbark Forest Description: Occurs on gently undulating rises, low hills and peneplains on infertile, often stony soils derived from a range of geologies. The open overstorey to 20 m tall consists of a variety of eucalypts, often including one of the Ironbark species. The mid storey often forms a dense to open small tree or shrub layer over an open ground layer ranging from a sparse to well-developed suite of herbs and grasses.
