| Short description | Eucalyptus leptophleba woodland on plains |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus leptophleba (Molloy red box) +/- E. platyphylla (poplar gum) +/- Corymbia clarksoniana (Clarkson's bloodwood) +/- C. tessellaris (Moreton Bay ash). Scattered canopy species +/- Melaleuca viridiflora (broad-leaved teatree) +/- Hakea persiehana occur in the subcanopy and/or shrublayer. The ground layer is mid-dense with Heteropogon contortus (black spear grass), H. triticeus (giant spear grass), Mnesithea rottboellioides (northern cane grass) (northern canegrass) and Themeda triandra (kangaroo grass). Occurs on higher older alluvial terraces and old colluvial sediments. Not a Wetland. (BVG1M: 9b). Vegetation communities in this regional ecosystem include: 3.5.25a: [RE not in use]²: This vegetation community is not mapped. Eucalyptus leptophleba (Molloy red box) dominates the sparse canopy. Corymbia tessellaris (Moreton Bay ash) is often subdominant. Scattered C. clarksoniana (Clarkson's bloodwood) and Erythrophleum chlorostachys (Cooktown ironwood) may also be present in the canopy. A sparse sub-canopy layer is sometimes present and is composed of a variety of species. The generally sparse shrub layer is composed of a mixture of species. Heteropogon contortus (black speargrass) is the most commonly encountered grass. It can often dominate the very sparse to dense variable ground layer. Occurs on higher older alluvial terraces and old colluvial sediments. Not a Wetland. (BVG1M: 9b). 3.5.25b: [RE not in use]²: This vegetation community is now mapped as 3.5.25. Eucalyptus leptophleba (Molloy red box) usually dominates the sparse canopy with E. platyphylla (poplar gum) a consistent subdominant canopy tree. Scattered Corymbia tessellaris (Moreton Bay ash) are also frequently present in the canopy. The sub-canopy tree layer is very sparse, and composed of a variety of shrubs including Melaleuca spp. and Eucalyptus spp. The shrub layer is also very sparse with a variety of shrubs occurring. The ground layer is mid-dense with Heteropogon contortus (black spear grass), H. triticeus (giant spear grass), Mnesithea rottboellioides (northern canegrass) and Themeda triandra (kangaroo grass). Occurs on higher older alluvial terraces and old colluvial sediments. Not a Wetland. (BVG1M: 9b). 3.5.25c: [RE not in use]²: This vegetation community is not mapped. Eucalyptus leptophleba (Molloy red box) dominates the very sparse to sparse canopy forming open woodlands or woodlands. Corymbia dallachiana (Dallachy's gum) is a frequent codominant tree in the open woodlands while C. clarksoniana (Clarkson's bloodwood) is often present in both structural formations. Other tree species are occasionally present in the woodlands. A very sparse sub-canopy tree layer is occasionally present in the open woodlands but more frequently in the woodlands. A very sparse shrub layer is sometimes present in which Grewia savannicola (dog's balls) and Planchonia careya (cocky apple) are the most commonly encountered. The ground layer is mid-dense to dense and dominated by a variety of grasses, including Heteropogon triticeus (giant spear grass), H. contortus (black spear grass) Sarga plumosum (plume sorghum) and Capillipedium parviflorum (scented top). Occurs on rolling plains. Not a Wetland. (BVG1M: 9b). |

| 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 | 3.5.25: South-east of bioregion. Alien forbs such as Crotalaria goreensis* and Stachytarpheta jamaicensis*, and grasses such as Themeda quadrivalvis* (grader grass) may occur at high densities. 3.5.25a: South-east of bioregion. Weed such as Sida spp., Mesosphaerum suaveolens and Corchorus sp. present. 3.5.25b: South-east of bioregion. Alien forbs such as Crotalaria goreensis* and Stachytarpheta jamaicensis*, and grasses such as Themeda quadrivalvis* (grader grass) may occur at high densities. 3.5.25c: North western Cape York Peninsula. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
