EVC/Bioregion Benchmark for Vegetation Quality Assessment Robinvale Plains bioregion EVC 809: Floodplain Grassy Wetland Description: Wetland dominated by floating aquatic grasses (which persist to some extent as turf during drier periods), occurring in the most flood-prone riverine areas. Typically treeless, but sometimes with thickets of saplings or scattered more mature specimens of Eucalyptus camaldulensis. Occupies temporary shallow lakes in the most flood-prone riverine areas, also occurs as a narrow intermediate band around some floodway ponds. Life forms: Life form #Spp %Cover LF code Medium Herb 5 10% MH Small or Prostrate Herb 3 5% SH Large Tufted Graminoid 1 5% LTG Medium to Small Tufted Graminoid 3 5% MTG Medium to Tiny Non-tufted Graminoid 4 60% MNG LF Code Species typical of at least part of EVC range Common Name MH Myriophyllum crispatum Upright Milfoil Ludwigia peploides montevidensis MH ssp.

Native Couch Recruitment: Episodic/Flood. Desirable period between disturbances is 5 years. Organic Litter: 10% cover Weediness: are no consistent weeds in this EVC. Logs: 5 m/0.1 ha.(where trees are overhanging the wetland) Ecological Vegetation bioregion benchmark
