Description [RE not in use]²: This regional ecosystem has been amalgamated into 2.3.29. Melaleuca saligna and M. stenostachya woodland on the wettest areas and M. viridiflora woodland, with occasional emergent Eucalyptus microtheca, on other areas. Dense ground cover of Eriachne burkittii, Panicum decompositum, Sarga plumosum, Schizachyrium spp. And Aristida spp. Sedge lands in some depressions. Occurs on closed depressions and shallow valley floors on Tertiary and Quaternary alluvium, seasonally flooded; soloths, solodised solonetz and leached grey and brown massive earths. Not a Wetland.

Eleocharis spp. are commonly excavated by feral pigs. 2.3.28x15: Subject to degradation from high total grazing pressure, particularly in the dry season. Eleocharis spp. are commonly excavated by feral pigs. 2.3.28x2: A rare ecosystem. Eleocharis spp. are commonly excavated by feral pigs.

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.

2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
