| Short description | Eucalyptus tetrodonta woodland on low to undulating granite hills |
| Structure code | Woodland |
| Description | Woodland of Eucalyptus tetrodonta (Darwin stringybark) +/- Corymbia clarksoniana (Clarkson's bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- C. stockeri (gum topped bloodwood). The very sparse to mid-dense subcanopy often includes canopy species +/- Acacia flavescens (red wattle) +/- Parinari nonda (nonda plum) +/- Grevillea glauca (clothespeg Grevillea). The very sparse shrublayer also includes juvenile Eucalyptus tetrodonta and mixed shrub species such as Planchonia careya (cocky apple), Persoonia falcata (geebung) or Acacia flavescens. Schizachyrium spp. (fire grass) and / or Heteropogon triticeus (giant spear grass) dominate the sparse to mid-dense grassy groundlayer +/- Sarga plumosum (plume sorghum) +/- Mnesithea rottboellioides +/- Thaumastochloa spp. Occurs mainly on low to undulating granite hills. Not a Wetland. (BVG1M: 14d). |

| Special values | 3.12.42: Potential habitat for NCA listed species: Acacia ommatosperma. |
| 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: 2-5 years. INTERVAL_MIN: 2. 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 | 3.12.42: RE 3.12.14, proposed new RE 3.12.15x1, 3.12.15x2 and vegetation community 3.12.19b were amalgamated in to this RE. C.stockeri is most likely to be subsp. stockeri. Occurs along the length of the Coen -Yambo Inlier from Musgrave to Portlands Rds. Also on ranges from north-west of Cooktown. |
