| Short description | Melaleuca spp. low woodland in bottoms of shallow valleys, on solodised soils |
| Structure code | Low Woodland |
| Description | Melaleuca nervosa, M. viridiflora, M. acacioides and Asteromyrtus symphyocarpa low woodland fringing valleys, with a grassy understorey of Aristida spp. and Chrysopogon fallax. On the valley bottoms, grassland dominated by Aristida spp., Eriachne spp., Sorghum spp. And Eragrostis basedowii. Occurs in shallow valleys on deep weathered Mesozoic sediments; solodised solonetz soils. Not a Wetland. (BVG1M: 21a). Vegetation communities in this regional ecosystem include: 2.3.36a: Melaleuca viridiflora and/or M. citrolens low woodland to low open woodland, occasionally with Asteromyrtus symphyocarpa, M. acacioides and Acacia torulosa. Emergent Corymbia polycarpa, C. clarksoniana, C. dallachiana and Livistona muelleri may occur. A sparse shrub layer may occur, including Melaleuca spp. and Petalostigma banksii. The ground layer is tussock grasses and sedges, including Eriachne spp., Aristida spp., Schizachyrium spp. and Fimbristylis spp. Occurs in drainage depressions in undulating Tertiary sand sheets in the north-east of the bioregion. Texture contrast soils. A narrow band of tussock grassland in the centre of depressions may occur. Not a Wetland. (BVG1M: 21a). |

| Special values | 2.3.36a: Potential habitat for the golden-shouldered parrot (Psephotus chrysopterygius). |
| Fire management guidelines | SEASON: Commence soon after wet season when just dry enough to carry fire. Occasional storm burns; high intensity fires caused by lightning are a feature of this system. INTENSITY: Low to moderate. INTERVAL: 1-3 years or longer, 3-5 years in the south (i.e., latitudes below Karumba) and in riparian areas. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Maintain a landscape mosaic of time since fire to break up fuel continuity through the landscape and to avoid impact of late season wildfire. Ensure good soil moisture. ISSUES: Repeat early season burns where there are overabundant seedlings and saplings is not recommended. |
