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.
