| Structure code | Woodland |
| Description | Melaleuca spp. low woodland to tall shrubland. Occasional other trees include Alphitonia excelsa, Erythrophleum chlorostachys, Grevillea parallela, G. pteridifolia, Petalostigma banksii and Lysiphyllum cunninghamii. The sparse ground cover includes Bothriochloa spp., Chrysopogon spp., Aristida pruinosa, Themeda triandra, Heteropogon contortus and a variety of short grasses and herbs. Occurs on seasonally waterlogged depressions and flats on Tertiary surface in the west of the bioregion. Yellow podzolic and lateritic podzolic soils. Not a Wetland. (BVG1M: 21a). Vegetation communities in this regional ecosystem include: 2.3.30a: Melaleuca viridiflora low woodland, commonly with Eucalyptus microtheca, E. pruinosa, E. chlorophylla and Corymbia polycarpa. Occurs on minor, active Quaternary alluvial plains and shallow depressions at the fringes of Tertiary lateritic landscapes around the Doomadgee Plains subregion. Texture contrast soils. Not a Wetland. (BVG1M: 21a). 2.3.30b: Melaleuca citrolens and M. stenostachya low woodland, commonly with Corymbia polycarpa, Excoecaria parvifolia, Terminalia oblongata subsp. volucris. Occurs in drainage depressions on Tertiary lateritic surfaces and their remnants around the Doomadgee Plains subregion. Sandy clay soils. Not a Wetland. (BVG1M: 21b). 2.3.30c: Melaleuca viridiflora low woodland to low open woodland, occasionally with Petalostigma banksii, Asteromyrtus symphyocarpa and other Melaleuca spp. Emergent Corymbia polycarpa may occur. M. viridiflora shrubs may occur. The ground layer is tussock grasses, including Schizachyrium fragile, Eragrostis fallax and Eriachne mucronata. Occurs in drainage depressions in dissected Tertiary lateritic landscapes around the Donors Plateau subregion. Texture contrast soils. Not a Wetland. (BVG1M: 21a). 2.3.30d: Melaleuca acacioides tall shrubland to low woodland. Terminalia platyptera may occur in the canopy. The ground layer is sparse, commonly with bare patches and tussock grasses. Occurs in drainage depressions in dissected Tertiary lateritic landscapes around the Donors Plateau subregion. Yellow-brown clay loam soils. Not a Wetland. (BVG1M: 21b). 2.3.30e: [RE not in use]²: This regional ecosystem is now mapped as 2.2.7x2. Melaleuca viridiflora low open woodland, commonly with Cochlospermum gregorii. Brachychiton diversifolius and Alphitonia pomaderroides may occur in the canopy. A shrub layer of M. viridiflora commonly occurs. The ground layer is tussock grasses, including Schizachyrium fragile and Chrysopogon fallax. Occurs on deep, sandy recent-Quaternary outwash deposits on coastal alluvial plain in the west of the bioregion. Not a Wetland. (BVG1M: 21a). |

| Special values | 2.3.30: Seasonal wetland. Important feeding sites for water birds. 2.3.30e: Seasonal wetland. Important feeding sites for water birds. |
| 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. |
| Comments | 2.3.30c: Was previously mapped as 2.3.31a. 2.3.30d: A rare vegetation community. Was previously mapped as 2.3.31b. 2.3.30e: Was previously mapped as 2.3.30c. |
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.
