| Subregion | 2, (5), (7.9) |
| Estimated extent1 | Pre-clearing 24000 ha; Remnant 2021 23000 ha |
| Short description | Eucalyptus leptophleba +/- E. platyphylla woodland on rolling metamorphic hills |
| Structure code | Woodland |
| Description | Eucalyptus leptophleba (Molloy red box) woodland usually with E. platyphylla (poplar gum). Scattered Corymbia tessellaris (Moreton Bay ash) are also often present in the canopy. The very sparse sub-canopy Melaleuca spp. and Eucalyptus spp. The very sparse shrub layer with canopy species and Planchonia careya (cocky apple) frequently present. The dense grassy ground layer can include dominants of Heteropogon contortus (black speargrass), H. triticeus (giant speargrass), Mnesithea rottboellioides (northern canegrass) and Themeda triandra (kangaroo grass). Occurs on rolling metamorphic hills. Not a Wetland. (BVG1M: 9b). |

| Special values | 3.11.12: Potential habitat for NCA listed species: Acacia guymeri. |
| 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 | 3.11.12: South-east of bioregion. Alien forbs such as Crotalaria goreensis*(Gamba pea) and Stachytarpheta jamaicensis*(snakeweed), and grasses such as Themeda quadrivalvis*(grader grass) occur at high densities this community. |
