| Short description | Corymbia bella +/- C. polycarpa, C. confertiflora, Grevillea striata, Pandanus sp. woodland on coastal dunes |
| Structure code | Low Woodland |
| Description | Corymbia bella low open woodland to woodland, commonly with C. polycarpa, C. confertiflora, Grevillea striata and Pandanus sp. Occasional canopy species include Eucalyptus pruinosa, Hakea arborescens, Atalaya hemiglauca, Acacia spp. and Terminalia spp.. A variable shrub layer commonly occurs, including Planchonia careya, Drypetes deplanchei and Diospyros humilis. The ground layer is tussock grasses, commonly Chrysopogon elongatus and Heteropogon contortus. Occurs on Quaternary coastal beach ridges and dunes. Not a Wetland. (BVG1M: 28a). Vegetation communities in this regional ecosystem include: 2.2.7x1: [RE not in use]²: This regional ecosystem is now mapped as 2.2.8. Grevillea striata low woodland, commonly with Atalaya hemiglauca. A variable shrub layer usually occurs, including canopy species, Alphitonia excelsa and Carissa lanceolata. The ground layer is tussock grasses, including Aristida spp., Sporobolus spp. and Chrysopogon fallax. Occurs on deflated coastal dunes, commonly at the landward margins of current dune systems. Pale to brown sands and sandy loams. Not a Wetland. (BVG1M: 28a). 2.2.7x2: Melaleuca viridiflora and/or M. citrolens low woodland to low open woodland, occasionally with M. stenostachya, Cochlospermum gregorii, Eucalyptus pruinosa subsp. pruinosa and Petalostigma pubescens. Other canopy species include Brachychiton diversifolius, Alphitonia pomaderroides, Dolichandrone heterophylla and Santalum lanceolatum. A variable shrub layer usually occurs. The ground layer is tussock grasses, including Sarga plumosum, Alloteropsis semialata, Schizachyrium fragile and Chrysopogon fallax. Occurs on older Quaternary (typically Pleistocene) coastal dunes. Orange to brown loamy sands to sandy loams. Not a Wetland. (BVG1M: 21a). |

| Fire management guidelines | SEASON: Commence early in dry season as soon as ground fuels can carry fire with fire extinguishing early evening. Continue to mid-dry season. INTENSITY: Low to moderate with occasional high intensity. INTERVAL: 1-5 years, but do not burn the same patches annually. Landscape mosaic should consist of patches with different times since burning. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Break up continuity of fuel across the landscape so that impact of late-season wildfire is minimised. Wildfire due to dry storms late in the dry season or in the early wet are natural occurrences, but they can burn over a wide area of the landscape with unwanted intensity and frequency. Use broad scale mosaic burning. ISSUES: Overabundant seedlings and saplings can lead to woody thickening if unchecked by fire. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. If ground fuels are sparse spell pastures prior to planned burns. Weeds such as buffel grass and rubbervine may be an issue for some tussock grass communities because weeds increase fuel loads leading to high intensity fires. |
| Comments | 2.2.7: Was previously mapped as 2.2.2a. Threatening processes include high total grazing pressure leading to wind erosion, and invasion by *Cryptostegia grandiflora (rubber vine) and other weeds such as Mesosphaerum suaveolens. 2.2.7x2: Was previously mapped as 2.3.30c. |
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.
