| Short description | Eucalyptus platyphylla +/- Corymbia clarksoniana woodland to open forest on flat wet plains |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus platyphylla (poplar gum). This species may be completely leafless at the end of the dry season. Scattered trees of Corymbia clarksoniana (Clarkson's bloodwood) and Erythrophleum chlorostachys (Cooktown ironwood) are often present in the canopy. A few sub-canopy trees may be present. Isolated low shrubs of Melaleuca viridiflora (broad-leaved teatree), Planchonia careya (cocky apple) and canopy species may be present. The ground layer is mid-dense to dense and dominated by grass species predominantly Heteropogon contortus (black speargrass) and Themeda triandra (kangaroo grass). Occurs on outwash plains and older higher alluvial terraces. Contains Palustrine. (BVG1M: 9b). |

| Special values | 3.5.26: Potential habitat for NCA listed species: Acacia guymeri. |
| Fire management guidelines | SEASON: Commence planned burns early in the dry season, after the wet season when dry enough to burn. Use occasional storm burns but generally avoid periods of extremely hot, dry conditions. INTENSITY: Low to moderate with occasional high during storm burns. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create varying stages of post-fire response. Burn 30-60% at the property level. ISSUES: To mitigate against the impact of late dry season fires, commence burning early in the season and continue through the dry to break up continuity of fuels across the landscape. Planned fire applied repeatedly early in the dry season may lead to woody thickening because fires are not of sufficiently high intensity; this may be exacerbated by stock grazing. Manage extent, intensity and frequency of fires judiciously, to avoid habitat tree loss. |
| Comments | 3.5.26: Occurs in the south-east of the bioregion near to the Wet Tropics Bioregion boundary. |
