| Description | Eucalyptus tereticornis +/- E. siderophloia and Corymbia intermedia open forest to woodland. Corymbia tessellaris, Lophostemon suaveolens and Melaleuca quinquenervia frequently occur and often form a low tree layer. Other species present in scattered patches or low densities include Angophora leiocarpa, E. exserta, E. grandis, E. latisinensis, E. tindaliae, E. racemosa and Melaleuca sieberi. Corymbia trachyphloia and/or C. citriodora subsp. variegata may dominate on areas of Pleistocene alluvia. Eucalyptus seeana may be present south of Landsborough and Livistona decora may occur in scattered patches or low densities in the Glenbar SF and Wongi SF areas. Occurs on Quaternary alluvial plains and drainage lines along coastal lowlands. Rainfall usually exceeds 1000mm/y. Contains Palustrine. (BVG1M: 16c). Vegetation communities in this regional ecosystem include: 12.3.11a: Open forest of Eucalyptus tereticornis and/or E. siderophloia, Lophostemon confertus with vine forest understorey. Other canopy species include Corymbia intermedia, Araucaria cunninghamii and Agathis robusta. Frequently occurring understorey species include Flindersia spp., Lophostemon suaveolens, L. confertus, Cupaniopsis parvifolia, Acronychia spp., Alphitonia excelsa and Acacia disparrima subsp. disparrima. Occurs on sub-coastal Quaternary alluvial plains. Rainfall usually exceeds 1000mm/y. Not a Wetland. (BVG1M: 16c). 12.3.11b: Eucalyptus tereticornis and/or E. racemosa subsp. racemosa +/- E. siderophloia, Lophostemon suaveolens, E. seeana, E. fibrosa subsp. fibrosa, E. propinqua and Angophora leiocarpa open forest usually with a dense shrub layer dominated by Melaleuca nodosa and/or Leptospermum polygalifolium. Occurs on Quaternary alluvium usually higher Pleistocene plains and terraces. Rainfall usually exceeds 1000mm/y. Contains Palustrine. (BVG1M: 16c). |

| Special values | 12.3.11: Potential habitat for NCA listed species: Acronychia littoralis, Alectryon ramiflorus, Arthraxon hispidus, Cupaniopsis shirleyana, Eulophia bicallosa, Gossia gonoclada, Macrozamia lomandroides, Macrozamia pauli-guilielmi, Marsdenia coronata, Maundia triglochinoides. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.3.11a: Habitat for threatened fauna species including the Black-breasted Button-quail Turnix melanogaster (Aridis, Melzer and Hamley, 1998). This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.3.11b: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Late summer, autumn and spring after rain. INTENSITY: Low. INTERVAL: 3-6 years. INTERVAL_MIN: 3. INTERVAL_MAX: 6. STRATEGY: Aim to burn 40-60% of any given area. Spot ignition in cooler or moister periods encourages mosaics. ISSUES: Maintain ground litter and fallen timber habitats by burning only with sufficient soil moisture. Burning should aim to produce fine scale mosaics of unburnt areas. |
| Comments | 12.3.11: Coastal and sub-coastal areas south of Bundaberg and a narrow coastal fringe north of Bundaberg. Extensively cleared and modified in populous southern parts of the bioregion. 12.3.11a: Understorey is a likely product of long term fire exclusion. Lenthall's Dam region west of Hervey Bay. Wongi SF and Tingalpa Ck. 12.3.11b: Flood plain areas south of Brisbane City including the Oxley Creek catchment. Extensively cleared and modified. |
