12.1 Plains Grasslands and Chenopod Shrublands - Clay soils
EVC 102 Low Chenopod Shrubland
Chenopod shrubland occupying broad, flat alluvial terraces occurring along the Murray River, west from Mildura to the border. Also found in narrow bands fringing raak and saline lakes such as Lake Tyrell and on relict lakebed surfaces such as Pine Plains. The field layer is characterised by succulents and a suite of annual herbs.
EVC 132 Plains Grassland
Treeless vegetation dominated by largely graminoid and herb life forms. Shrubs and trees may be also occasionally present.
EVC 654 Creekline Tussock Grassland
Occurs along low gradient ephemeral and intermittent drainage lines across the volcanic plains. Soils are generally fertile heavy dark clays. Exposed basalt rocks can be common. Dominated by a dense sward of Common Tussock-grass Poa labillardierei primarily with small herbs and typically mat-forming grasses in the inter-tussock spaces. This EVC often includes small areas of sedgeland and/or wetland.
EVC 806 Alluvial Plains Semi-arid Grassland
Grassland (turf) to herbland with only incidental shrubs. Flood-promoted flora, potentially including a wide range of opportunistic ephemeral / annual species occupying low-lying areas within at least previously flood-prone (mostly) higher-level terraces, which may be effectively shallow lakes when flooded. Also sometimes on flats along creeks of the further north-west, in habitat akin to that of Floodway Pond Herbland.
EVC 826 Plains Savannah
A structurally diverse vegetation unit which includes 'grassy openings' of a few to many hundreds of hectares, with a variable tree density ranging from a very sparse savannah to woodland. The relative absence of eucalypts is particularly characteristic, with Buloke Allocasuarina luehmannii and perhaps Slender Cypress-pine Callitris gracilis ssp. murrayensis being the dominant trees. Widespread on the northern plains.
EVC 829 Chenopod Grassland
Open to sparse shrubland with a more or less continuous tussock grass sward found on heavy somewhat sodic clay plains fringing the active floodplains of major watercourses such as the Loddon and Avoca Rivers.
EVC 124 Grey Clay Drainage-line Aggregate
Comprises a group of communities associated with inundation-prone habitat of slightly mineralised drainage-lines in more elevated parts of the basalt plains. The EVC is rare and localised, identified from very few locations, and includes habitat of the extremely localised Curly Sedge Carex tasmanica. The components of Brackish Herbland, Plains Brackish Sedge Wetland and Brackish Aquatic Herbland are also variously recognisable within the aggregate.
EVC 1088 Riverine Grassland
Grassland dominated by Austrodanthonia spp., occurring on relatively elevated sites on riverine alluvium, prone to seasonal water-logging, but flooding shallow and superficial when and if it occurs. Distribution limited to small patches on the Murray River floodplain
Bioregional Conservation Status and EVC benchmarks
An EVC may have a different conservation status in each bioregion in which it is found. To look up an EVC's Bioregional Conservation Status (BCS), download the spreadsheet on the Simplified Native Vegetation Groups page.
You can also use this spreadsheet to help find the corresponding EVC benchmarks, which are listed by bioregion.
