EVC/Bioregion Benchmark for Vegetation Quality Assessment Robinvale Plains bioregion EVC 103: Riverine Chenopod Woodland (syn. 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. trees: Species Eucalyptus largiflorens DBH(cm) 40 cm #/ha 5/ha Tree Canopy Cover: %cover Character Species Common Name 10% Eucalyptus largiflorens Acacia stenophylla Black Box River Coobah Understorey: Life form Immature Canopy Tree #Spp 5% LF code IT Medium 3 30% MS Small Shrub 5 25% SS Prostrate 1 1% PS Medium Herb 5 5% MH or Prostrate Herb* 5 10% SH Medium to Small Tufted Graminoid 2 5% MTG Largely seasonal life form Total understorey projective foliage cover 50% LF Code MS Species typical of at least part of EVC range Atriplex nummularia Common Name Old-man Saltbush MS Chenopodium nitrariaceum Nitre Goosefoot MS Eremophila divaricata ssp. divaricata Spreading Emu-bush SS Sclerolaena tricuspis Streaked Copperburr SS Enchylaena tomentosa var. tomentosa Ruby Saltbush SS Atriplex lindleyi Flat-top Saltbush SS Rhagodia spinescens Hedge Saltbush PS Sclerochlamys brachyptera Short-wing Saltbush MH Einadia nutans ssp. nutans Nodding Saltbush MH Calocephalus sonderi Pale Beauty-heads MH Senecio glossanthus Slender Groundsel MH Brachyscome lineariloba Hard-head SH Disphyma crassifolium ssp. clavellatum Rounded Noon-flower SH Maireana pentagona Bluebush Recruitment: Continuous Organic Litter: 10 % cover Logs: 5m/0.1 ha.

EVC/Bioregion Benchmark for Vegetation Quality Assessment Robinvale Plains bioregion EVC 818: Shrubby Riverine Woodland Description: Eucalypt woodland to open forest to 15 m tall of less flood-prone (riverine) watercourse fringes, principally on levees and higher sections of point-bar deposits. The understorey includes a range of species shared with drier floodplain habitats with a sparse shrub component, ground-layer patchily dominated by various life-forms. A range of large dicot herbs (mostly herbaceous perennial, several with a growth-form approaching that of small shrub) are often conspicuous.
