| Short description | Corypha utan open woodland on alluvial plains |
| Structure code | Open Woodland |
| Description | Corypha utan (Gebang palm) open woodland to woodland +/- Eucalyptus acroleuca (Lakefield coolabah) +/- Melaleuca saligna. Scattered Antidesma ghaesembilla and Strychnos lucida (strychnine bush) can occur in a very sparse shrublayer and/or subcanopy along with canopy species. The mid layers are generally absent but scattered canopy species and Antidesma spp. Can occur. The dense mixed grassy ground layer can contain a range of sedge and grass species. Occurs on alluvial plains. Not a Wetland. (BVG1M: 28b). |

| Fire management guidelines | SEASON: Progressive early to mid-dry season, followed by storm time burns. INTENSITY: Moderate to high. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn when fires will carry, which is generally Sep to Oct. Begin burning early in the fire season, followed by progressive patch fires burnt through the year. Burn up to 50% in any year. ISSUES: Patch burning should aim to create a mosaic of burnt and unburnt patches in order to impede wildfire. Storm burning can be used to promote perennial grasses and prevent vegetation thickening. Reduction in cattle grazing may be required to produce adequate fire intensity. Thickening up of some patches could be due to a decreased fire frequency. |
| Comments | 3.3.34: Northern Lakefield NP. The naturalised grass Urochloa subquadripara* can dominate the ground-layer. Feral pigs selectively feed on the seeds severly reducing their reproductive viability. |
