| Structure code | Open Forest |
| Description | Casuarina cunninghamiana (river oak) woodland to open forest on alluvium fringing streams. Occurs on channel benches, levees and terraces on deep loamy sands or sandy clay loams (often with loose surface gravel). Riverine. (BVG1M: 16a). Vegetation communities in this regional ecosystem include: 7.3.26a: Casuarina cunninghamiana, Eucalyptus tereticornis, Lophostemon suaveolens, Melaleuca leucadendra, M. fluviatilis, Buckinghamia celsissima, Mallotus philippensis woodland and forest with an understorey of Melaleuca viminalis and Bursaria tenuifolia. Fringing forests of larger streams. Riverine. (BVG1M: 16a). 7.3.26b: Casuarina cunninghamiana woodland and forest. Fringing forests of larger streams. Riverine. (BVG1M: 16a). |

| Special values | 7.3.26: Important wildlife corridors in cleared landscapes. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Perimeter burning early in the fire season may limit the extent and intensity of wildfire incursions. Burning may be useful for weed management. ISSUES: Coastal she-oaks and river oaks are sensitive to fire. Fire in the litter layer of these oaks will be of low intensity and patchy. Storm burning may be useful to minimise scorch intensity to fire sensitive Casuarina. No active fire management required, except as part of weed control. Fire could be useful in controlling Singapore daisy, Sphagneticola trilobata, Lantana camara and high biomass grasses. |
| Comments | 7.3.26: Scattered along the drier, northern, southern and western extremes of the bioregion. Severely affected by weed invasion, including species such as Lantana camara and Mesosphaerum suaveolens. |
