| Short description | Eucalyptus leptophleba and Corymbia clarksoniana woodland or C. disjuncta woodland on steep to low igneous hills |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus leptophleba (Molloy red box) and Corymbia clarksoniana (Clarkson's bloodwood) or C. disjuncta (cabbage gum) woodland. Occur on steep to low granite hills. Not a Wetland. (BVG1M: 9b). Vegetation communities in this regional ecosystem include: 3.12.18a: Woodland to open woodland of Eucalyptus leptophleba (Molloy red box) often with Corymbia clarksoniana (Clarkson's bloodwood) as a subdominant. E. platyphylla (poplar gum) may be codominant when it occurs. A very sparse to sparse subcanopy contains canopy species, Dendrolobium umbellatum (horse bush) or Acacia rothii. Similar species occur in a very sparse to sparse shrub layer with Canarium australianum (mango bark) or Ficus opposita (sandpaper fig) often occurring. The mid-dense to dense grassy groundlayer is dominated by Heteropogon contortus (black spear grass), H. triticeus (giant speargrass), and Mnesithea rottboellioides (northern cane grass) +/- Sarga plumosum (plumed sorghum) +/- Panicum spp. +/- Capillipedium parviflorum +/- Themeda triandra (kangaroo grass). Occurs on steep to low granite hills. Not a Wetland. (BVG1M: 9b). 3.12.18b: Woodland to low open woodland of Corymbia disjuncta (cabbage gum) +/- C. clarksoniana (Clarkson's bloodwood). Scattered C. disjuncta, Dendrolobium umbellatum (horsebush), Erythrophleum chlorostachys (Cooktown ironwood) and Piliostigma malabaricum (lilac Bauhinia) can occur in the very sparse subcanopy and shrublayer. Heteropogon spp. (speargrass) +/- Imperata cylindrica (blady grass) dominate the dense grassy ground layer. Occurs on slopes of steep granite hills. Not a Wetland. (BVG1M: 9b). |

| 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 | 3.12.18: 3.12.17 and 3.12.19a were amalgamated in to this RE. Occurs from Musgrave to Temple Bay on Coen-Yambo Inlier. Small area near Bamaga. 3.12.18a: Central Peninsula along the Great Dividing Range. 3.12.18b: Restricted to hills northeast of Archer River Roadhouse. |
