EVC/Bioregion Benchmark for Vegetation Quality Assessment Victorian Riverina bioregion EVC 810: Floodway Pond Herbland Description: Low herbland to < 0.3 m tall with occasional emergent life forms, usually with a high content of ephemeral species. Floors of ponds associated with floodway systems. Typically heavy deeply cracking clay soils. Characteristically smaller wetlands with a more regular flooding and drying cycle in comparison to sites supporting Lake Bed Herbland.
