| Description | Melaleuca viridiflora low open woodland to low woodland, commonly with M. citrolens and M. stenostachya with a grassy understorey of Aristida spp. Occurs in depressions and broad valleys on Tertiary surfaces in the east of the bioregion. Solodised solonetz soils. Not a Wetland. (BVG1M: 21a). Vegetation communities in this regional ecosystem include: 2.3.29a: Melaleuca viridiflora low woodland to low open woodland, occasionally with M. citrolens, M. stenostachya. M. acacioides, Grevillea striata and Terminalia spp. may occur in the canopy. Emergent Corymbia polycarpa, Eucalyptus chlorophylla, E. microtheca and C. clarksoniana may occur. A shrub layer commonly occurs, including Melaleuca spp., Petalostigma spp. and Carissa lanceolata. The ground layer is tussock grasses, commonly Eriachne spp. Occurs on active Quaternary alluvial plains and drainage depressions in the north-east of the bioregion. Silty clay and texture contrast soils. Not a Wetland. (BVG1M: 21a). 2.3.29b: Melaleuca spp. low open woodland to low woodland, occasionally with Eucalyptus microtheca. A sparse shrub layer may occur, including Melaleuca spp., Acacia spp. and Petalostigma banksii. The ground layer is tussock grasses, including Aristida hygrometrica and Sarga plumosum. Occurs on active Quaternary alluvial plains and drainage depressions on Tertiary surfaces in the south-east of the bioregion. Sandy and silty clay soils. Not a Wetland. (BVG1M: 21a). 2.3.29c: Melaleuca viridiflora low open woodland to woodland, occasionally with M. citrolens and M. stenostachya. Emergent Corymbia polycarpa, Eucalyptus chlorophylla and C. dallachiana may occur. A shrub layer commonly occurs, including Melaleuca viridiflora and Petalostigma banksii. The ground layer is tussock grasses, including Eriachne spp., Schizachyrium fragile and Aristida spp. Occurs on old alluvial plains (recent Pleistocene surface) in the north-east of the bioregion. Grey-brown sandy loam and sandy clay loam soils. Not a Wetland. (BVG1M: 21a). 2.3.29x2a: [RE not in use]²: This vegetation community is now mapped as 2.3.59a. Melaleuca acacioides and/or M. foliolosa and/or Excoecaria parvifolia and/or Hakea pedunculata tall open shrubland. The ground layer is a combination of tussock grasses and sedges, including Schizachyrium sp., Aristida spp., Fimbristylis spp. and Eleocharis sp. Occurs on coastal alluvial surfaces adjacent to the tidal zone and subject to erosion. Saline clay soils. Not a Wetland. (BVG1M: 21b). 2.3.29x2b: [RE not in use]²: This vegetation community is now mapped as 2.3.59b. Mixed tall open shrubland to low open woodland including combinations of the species Excoecaria parvifolia, Melaleuca acacioides, Eucalyptus microtheca, Casuarina cunninghamiana, Atalaya hemiglauca and Grevillea striata. The ground layer is tussock grasses, including Xerochloa imberbis, Schizachyrium sp. and Chrysopogon sp. Occurs on coastal alluvial surfaces adjacent to the tidal zone and subject to erosion. Saline clay soils. Not a Wetland. (BVG1M: 27c). 2.3.29x42a: [RE not in use]²: This vegetation community is now mapped as 2.3.60. Melaleuca acacioides and/or M. foliolosa tall shrubland to low woodland, commonly with Excoecaria parvifolia. M. citrolens, Eucalyptus microtheca, M. viridiflora, Terminalia platyptera and Petalostigma banksii may occur in the canopy. The ground layer is sparse, commonly with bare patches and tussock grasses. Contains small areas of bare ground or open tussock grassland. Occurs on Quaternary alluvial plains and breakaways, commonly subject to erosion. Yellow-brown silty clay loam soils. Not a Wetland. (BVG1M: 21b). |

| Special values | 2.3.29: Provides wetland habitat for a flora and fauna. 2.3.29a: Potential habitat for the golden-shouldered parrot (Psephotus chrysopterygius). 2.3.29b: Provides wetland habitat for a flora and fauna. 2.3.29c: Potential habitat for the golden-shouldered parrot (Psephotus chrysopterygius). |
| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 3-5 years. INTERVAL_MIN: 3. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Buffering unnecessary unless associated with fire management within vegetation unit. ISSUES: Restrict extent and intensity of fires. High intensity and extensive fires will degrade vegetation structure and destroy animal habitats. Burn only under mild conditions. |
| Comments | 2.3.29: More information required to confirm conservation status. Floristic changes occurring due to high grazing pressure. 2.3.29a: Was previously mapped as 2.3.28a. 2.3.29b: More information required to confirm conservation status. Floristic changes occurring due to high grazing pressure. 2.3.29c: Was previously mapped as 2.3.28b. |
1 Estimated extent is from version 13 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.
