Structure

Open chenopod shrubland with groundcover of forbs and grasses

Trees

None

Shrubs and vines

Atriplex vesicaria, Sclerostegia tenuis, Malacocera tricornis, Maireana aphylla, Atriplex nummularia, Rhagodia spinescens, Enchylaena tomentosa, Nitraria billardieri

Forbs, graminoids and pteridophytes

Disphyma crassifolium ssp. clavellatum, Minuria cunninghamii, Sclerolaena tricuspis, S. muricata, S. brachyptera, S. bicornis var. bicornis, S. intricata, S. stelligera, Ixiolaena tomentosa, Leptorhynchos panaetioides, Calocephalus sonderi, Frankenia connata, Dissocarpus biflorus var. biflorus, Atriplex lindleyi, A. pseudocampanulata, Osteocarpum acropterum var. deminuta, Daucus glochidiatus, Rhodanthe corymbiflora, Plantago cunninghamii, Podolepis muelleri, Sida trichopoda, Vittadinia cuneata var. cuneata, Brachyscome lineariloba, Chloris truncata, Sporobolus caroli, Agrostis avenacea, Austrodanthonia caespitosa

Habitat

Extensive level or depressed alluvial plains and dry lake beds, often semi-saline, with deep grey-brown clays on semi-arid floodplains

Distribution

Seldom flooded parts of the lower Murray-Murrumbidge-Lachlan floodplains, and on the upper Darling and Paroo floodplains, principally in NSW, but likely to occur on restricted areas of Murray floodplains in Vic and SA.

Notes

Extensive group of assemblages on the southern floodplains, sharing floristic affinites with Riverine plains woodlands and grasslands, and Aeolian chenopod shrublands. Extensively degraded by overgrazing, which has lead to declining populations of certain Atriplex species.
