Regional ecosystem details for 9.5.3
| Regional ecosystem | 9.5.3 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, 5, 2, (4.6) |
| Estimated extent1 | Pre-clearing 185000 ha; Remnant 2021 181000 ha |
| Short description | Eucalyptus crebra or E. drepanophylla and Corymbia clarksoniana woodland on sand plains |
| Structure code | Woodland |
| Description | Woodland of Eucalyptus crebra (narrow-leaved ironbark) and Corymbia clarksoniana (Clarkson's bloodwood) +/- C. dallachiana (Dallachy's gum) +/- C. tessellaris (Moreton Bay ash) +/- C. erythrophloia (red bloodwood) +/- E. brownii (Reid River box). In some areas E. drepanophylla or E. exilipes may replace E. crebra. A sub-canopy with canopy species and Grevillea spp. can occur. The shrub layer ranges from none to open and includes scattered specimens of canopy species, Atalaya hemiglauca (whitewood), Denhamia cunninghamii (yellowberry bush), Petalostigma spp., Erythroxylum australe (cocaine tree) and Carissa spp. (currantbush). There is a mid to dense grassy ground layer of mixed species which can include Heteropogon spp., Themeda triandra (kangaroo grass), Aristida spp. and Chrysopogon fallax (golden beard grass). Occurs on flat to gently undulating Quaternary sandplains and sandsheets. Not a Wetland. (BVG1M: 18b). |

| Fire management guidelines | SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. INTENSITY: Low, with occasional moderate. INTERVAL: 2-5 year intervals with longer unburnt patches. Fuel loads tend to reach a maximum after 2-3 years. Ensure burn programs occur after big wet season as fuel loads will be higher than average. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Burn less than 40% across the landscape in any year. Burning through the early dry season will produce a network of burns that will contain later fires. Fires will only gain in intensity as the dry season progresses. Grass composition can be affected by timing and intensity of fire. Occasional moderate fire will help to reduce overabundant trees that could potentially suppress ground layer vegetation. ISSUES: Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. |
| Comments | 9.5.3: Occurs extensively in the south of the bioregion. |
