Bioregional Conservation Status and EVC benchmarks
17.1 Mallee - Siliceous sands
EVC 87 Lowan Sands Mallee
Low woodland to mallee shrubland commonly dominated by the mallee form Desert Stringybark Eucalyptus arenacea with a heathy understorey. Found on deep to moderately deep siliceous sands of aeolian origin.
EVC 88 Heathy Mallee
Low mallee shrubland to low open mallee shrubland with a dense to moderately dense understorey of heathy shrubs. Occurs on infertile siliceous Lowan Sand on dunefields and sandplains. This is a prominent EVC in the central Big Desert.
EVC 91 Loamy Sands Mallee
Semi-arid low mallee shrubland, typically supporting scattered shrubs above a hummock grass field layer. Typically occurs on deep drifts of Lowan sands in the lee of ridge systems or occupying dune crests and swales in the parabolic and irregularly arranged dune in the Central Mallee and Sunset Country.

17.2 Mallee - Calcareous dunefields
EVC 86 Woorinen Sands Mallee
Mallee shrubland, typically supporting a hummock grass (Triodia spp.) dominated understorey. This EVC could be considered intermediate between the heavier soil mallee woodlands and the lighter sandy soil mallee vegetation predominant on Lowan (siliceous) sand.
EVC 158 Chenopod Mallee
Open to very open mallee woodland almost invariably dominated by Yorrell Eucalyptus gracilis, supported by thin Woorinen deposits typically overlying gypsiferous and sodic clays. In undisturbed remnants this EVC is characterised by the dominance of saltbushes and semi-succulent understorey shrubs.
EVC 824 Woorinen Mallee
Widespread mallee woodland, associated with the east-west orientated calcareous dunefields of the Woorinen Formation with a low, open chenopod dominated shrub understorey. A diverse array of sub-shrubs, forbs and grasses are also present. Typically occurs on fine textured red-brown sandy loam and clay loam soils.
17.3 Mallee - Clay plains
EVC 96 Ridged Plains Mallee
Open, quite grassy mallee woodland, typical of the gently undulating "plains" of the Wimmera and Southern Mallee. Soils are somewhat variable but are typically duplex with grey or brown sandy clay loam or clay loam topsoils of aeolian origin.
17.4 Mallee - Sandstone ridges and rises
EVC 93 Sandstone Ridge Shrubland
Low open mallee typically with a tall shrubby understorey, or shrubland with scattered emergent mallees. A good field character for this EVC is the dominance or co-dominance of the tall shrub Broombush Melaleuca uncinata in shrubland or as an understorey shrub in Mallee vegetation. Confined to the crests of outcropping Parilla sandstone ridges and also where these ridges are at least partially obscured by a shallow mantle of Lowan sand.
EVC 95 Red Swale Mallee
Dense to sometimes whipstick form of mallee shrubland with a typically sparse understorey. This EVC does not necessarily occur in dune swales, however it is often found on low points in the jumbled or parabolic dunefields of the Lowan where the underlying Parilla ridges may be "exposed" and are mantled by a thin layer of aeolian material.
EVC 981 Parilla Mallee
Open mallee supported by shallow accumulations of aeolian material that have been deposited on the slopes of prominent Parilla Sandstone ridges. The understorey is highly variable comprising numerous floristic variants many of which appear to be strongly influenced by land use and fire regime. A well-developed woody shrub layer is typical in relatively undisturbed remnants.

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.
