| Short description | Eucalyptus tetrodonta and Corymbia stockeri woodland on ironstone knolls and slopes |
| Structure code | Woodland |
| Description | Eucalyptus tetrodonta (Darwin stringybark) woodland to open woodland commonly with Corymbia stockeri and occasionally Erythrophleum chlorostachys (Cooktown ironwood). The very sparse subcanopy contains canopy species commonly with Grevillea spp., Acacia rothii and canopy species. The very sparse to sparse shrub layer contains canopy species and commonly Acacia calyculata. Dominants in the mid-dense grassy ground layer can include Sarga plumosum, Heteropogon triticeus and Schizachyrium spp. Occurs on ironstone knolls, escarpments and slopes. Not a Wetland. (BVG1M: 14b). |
| Protected areas | Oyala Thumotang NP (CYPAL), Olkola NP (CYPAL) |
| 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 | 3.7.4: RE 3.7.5 was malagamated into this RE. May occur on marginally deeper soils as well as shallow soils on undulating rises. Ironstone pebbles on the surface are a conspicuous feature. Weipa plateau and Merluna Plain. |
