| Short description | Corymbia clarksoniana, Eucalyptus brassiana open forest on granite ranges |
| Structure code | Open Forest |
| Description | Open forest of Corymbia clarksoniana (Clarkson's bloodwood) and Eucalyptus brassiana (Cape York redgum) +/- C. stockeri (gum topped bloodwood) +/- E. cullenii (Cullen's ironbark) +/- Erythrophleum chlorostachys (Cooktown ironwood). A sparse to mid-dense subcanopy can contain Melaleuca nervosa (woodland paperbark), Acacia spp., Allocasuarina littoralis (black sheoak) as well as rainforest species such as Euroschinus falcatus, Chionanthus ramiflorus (northern olive), Calophyllum sil (alligator bark), Buchanania arborescens (satinwood) and Celtis paniculata. The sparse shrublayer can contain canopy species as well as Alyxia spicata (chain fruit), Wikstroemia indica and Dendrolobium umbellatum (horse bush). The very sparse to sparse grassy groundlayer include Heteropogon spp. Or Imperata cylindrica. Occurs on granite ranges. Not a Wetland. (BVG1M: 9c). |

| Protected areas | KULLA (McIlwraith Range) NP (CYPAL), Cape Melville NP (CYPAL), Oyala Thumotang NP (CYPAL), KULLA (McIlwraith Range) RR, Ngalba-bulal NP (CYPAL) |
| Special values | 3.12.7: Potential habitat for NCA listed species: Argophyllum verae, Brachychiton grandiflorus, Cecarria obtusifolia, Dockrillia wassellii. |
| 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 | 3.12.7: The C.stockeri is likely to be C.stockeri subsp. stockeri. Occurs on western McIlwraith Range and the Melville Range. |
