| Short description | Eucalyptus tetrodonta +/- E. cullenii, Corymbia stockeri and Melaleuca spp. woodland on remnant surfaces |
| Structure code | Woodland |
| Description | Woodland of Eucalyptus tetrodonta (Darwin stringybark) and E. cullenii (Cullen's ironbark) or E. tetrodonta and C. stockeri (gum topped bloodwood) +/- Melaleuca spp. Occurs on weathered remnant surfaces often with ironstone nodules to surface. Not a Wetland. (BVG1M: 14b). Vegetation communities in this regional ecosystem include: 3.5.38a: Woodland of Eucalyptus tetrodonta (Darwin stringybark) and Corymbia stockeri (gum topped bloodwood) +/- E. cullenii (Cullen's ironbark) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- Corymbia spp. The very sparse subcanopy contains a combination of Melaleuca viridiflora (broad-leaved teatree), Grevillea glauca (clothespeg Grevillea) or Acacia spp. The very sparse to sparse shrub layer can contain juvenile canopy species or Petalostigma banksii (smooth-leaved quinine). Heteropogon triticeus (giant spear grass) and Sarga plumosum (plume sorghum) are often dominant in the sparse to mid-dense grassy groundlayer. Occurs on weathered remnant surfaces often with ironstone nodules to surface. Not a Wetland. (BVG1M: 14b). 3.5.38b: Woodland of Eucalyptus tetrodonta (Darwin stringybark) +/- Corymbia stockeri (gum topped bloodwood). Melaleuca stenostachya (fibre-barked teatree) is often prominent in both the canopy and sub-canopy with M. viridiflora (broad-leaved teatree) and Acacia spp. also found in in the very sparse to sparse sub-canopy. The very sparse shrub layer can contain scattered juvenile canopy species, Coelospermum reticulatum (medicine bush) or Petalostigma banksii (smooth-leaved quinine). The sparse to mid-dense mixed grassy groundlayer can include Alloteropsis semialata (cockatoo grass), Heteropogon triticeus (giant spear grass), Sarga plumosum (plume sorghum), Schizachyrium spp. or Pseudopogonatherum contortum. Occurs on weathered remnant surfaces often with ironstone nodules to surface. Not a Wetland. (BVG1M: 14b). |

| 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 | 3.5.38: Vegetation communities 3.5.8c, 3.5.9d (part) and proposed new vegetation community 3.5.7x2c were amalgamated in to this RE. C. stockeri is likely to be subsp. peninsularis. Central plains on the Peninsula from Musgrave to the Torres Strait Islands. 3.5.38a: Both subspecies of Corymbi stockeri may occur. Occurs on weathered remnant surfaces often with ironstone nodules to surface. Melaleuca stenostachya may occur but will have lower biomass than the C. stockeri and Eucalyptus cullenii. Central plains on the Peninsula from Musgrave to the Torres Strait Islands. 3.5.38b: C.stockeri is likely to be subsp. peninsularis. On weathered remnant surfaces often with ironstone nodules to surface. Occurs in the central Peninsula from Coen to Bramwell Junction. |
