| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.24. Woodland of Eucalyptus leptophleba (Molloy red box) +/- Corymbia tessellaris (Moreton Bay ash) +/- E. platyphylla (poplar gum). The sub-canopy and shrub layer are generally sparse though the shrub layer can be mid-dense. Associated with riverine levees and floodplains. Not a Wetland. (BVG1M: 16b). Vegetation communities in this regional ecosystem include: 3.3.25a: [RE not in use]²: This vegetation community is now mapped as 3.3.24. Eucalyptus leptophleba (Molloy red box) dominates the sparse canopy (18-25m tall). Corymbia tessellaris (Moreton Bay ash) is often subdominant. Scattered Corymbia clarksoniana (Clarkson's bloodwood) and Erythrophleum chlorostachys (Cooktown ironwood) may also be present in the canopy. A very sparse to sparse sub-canopy layer (6-15m tall) is sometimes present and is composed of a variety of species. The shrub layer (0.5-2.5m tall) varies from sparse to mid-dense and is composed of a variable 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. Associated with riverine levees and floodplains. Not a Wetland. (BVG1M: 16b). 3.3.25b: [RE not in use]²: This vegetation community is now mapped as 3.3.24. 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 Melaleuca spp. and Eucalyptus spp. The shrub layer is also very sparse, with M. nervosa, Corymbia clarksoniana (Clarkson's bloodwood), E. leptophleba and Planchonia careya (cocky apple) frequently occurring, and Antidesma ghaesembilla dominating this layer at one site. The ground layer is mid-dense with Heteropogon contortus (black spear grass), H. triticeus (giant spear grass), Mnesithea rottboellioides (northern cane grass) and Themeda triandra (kangaroo grass) the most frequent native grasses. Occurs on floodplains. Not a Wetland. (BVG1M: 9b). 3.3.25c: [RE not in use]²: This vegetation community is now mapped as 3.3.24. Eucalyptus leptophleba (Molloy red box) dominates the sparse canopy. Corymbia clarksoniana (Clarkson's bloodwood), C. tessellaris (Moreton Bay ash) and E. platyphylla (poplar gum) are frequently present as scattered trees. Other Eucalyptus spp. may also be occasionally present. The sub-canopy and shrub layers are very sparse. The ground layer is mid-dense and dominated by the grasses, Heteropogon contortus (black spear grass) and Themeda triandra (kangaroo grass). Frequent native forbs are Crotalaria montana, C. calycina and Glycine spp. Occurs on sandstone colluvium. Not a Wetland. (BVG1M: 11c). |
| Special values | 3.3.25: Potential habitat for NCA listed species: Homoranthus tropicus. |
| 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: 1-3 years. INTERVAL_MIN: 1. INTERVAL_MAX: 3. 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. These communities require particular management attention due to issues of grazing, weed invasion, rapid fuel accumulation, poor access and woody thickening. Fuel can reach maximum accumulation in 2 years. |
| Comments | 3.3.25: Weedy forbs such as Sida spp., Mesosphaerum suaveolens (hyptis) and Corchorus sp. (jute) occur and may form dense stands at some sites. Widespread throughout the centre and south-east of the bioregion. 3.3.25a: Widespread throughout central and south-east Peninsula. 3.3.25b: South-east of bioregion. Alien forbs such as Crotalaria goreensis* (gambia pea) and Stachytarpheta jamaicensis* (snake weed), and grasses such as Themeda quadrivalvis* (grader grass) occur at high densities in many areas. 3.3.25c: Hopevale. Crotalaria goreensis* (gambia pea) and Mesosphaerum suaveolens* (hyptis) and Themeda quadrivalvis* (grader grass) are often abundant . |
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.
