| Short description | Eucalyptus tetrodonta +/- Corymbia clarksoniana woodland on sand plains |
| Structure code | Woodland |
| Description | Woodland to very occasionally open forest dominated by Eucalyptus tetrodonta (Darwin stringybark) +/- Corymbia clarksoniana (Clarkson's bloodwood) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- Corymbia spp. A very sparse to sparse subcanopy can occur. The very sparse to sparse mixed shrub layer often contains juvenile canopy species. Common species in the sparse to dense grassy groundlayer are Sarga plumosum (plume sorghum), Schizachyrium spp. (fire grass) or Heteropogon triticeus (giant spear grass). Occurs on outwash plains. Not a Wetland. (BVG1M: 14b). Vegetation communities in this regional ecosystem include: 3.5.39x1: Low woodland to low open forest of Thryptomene oligandra and Melaleuca viridiflora +/- Neofabricia mjoebergii +/- Acacia torulosa +/- Grevillea pteridifolia. Emergents of Eucalyptus tetrodonta and Corymbia clarksoniana sometimes occur. The very sparse to sparse sub canopy contains canopy species+/- Jacksonia thesioides. The very sparse shrub layer also includes juvenile canopy species +/- Alyxia spicata +/- Styphelia ruscifolia. The very sparse to sparse ground layer usually has Panicum spp., Schizachyrium spp. and hydrophilic species such as Drosera spp. and Stylidium spp. Occurs on seepage areas fringing Tertiary plains. Palustrine. (BVG1M: 28c). |

| Special values | 3.5.39: Potential habitat for NCA listed species: Acacia armitii, Dendrobium johannis, Habenaria rumphii, Jedda multicaulis, Samadera sp. (Kennedy River J.R.Clarkson 5645), Stemona angusta. 3.5.39x1: High diversity of plant species due to seepage from higher in landscape. |
| 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 | 3.5.39: REs 3.5.7, 3.5.12, 3.5.10 (part) and proposed new RE 3.5.7x2 were amalgamated in to this RE. Mainly occurs on plains in the Laura basin, but also in the central west Peninsula and on some Torres Strait Islands. 3.5.39x1: Was previously mapped as RE 3.3.33. Widespread across the south of the bioregion. |
