Regional ecosystem details for 9.5.16
| Regional ecosystem | 9.5.16 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 2, 1, (3), (5), (2.6), (6) |
| Estimated extent1 | Pre-clearing 35000 ha; Remnant 2021 34000 ha |
| Short description | Eucalyptus tetrodonta +/- Erythrophleum chlorostachys woodland on Tertiary remnants |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus tetrodonta (Darwin stringybark) frequently with Erythrophleum chlorostachys (Cooktown ironwood) +/- Corymbia clarksoniana (Clarkson's bloodwood) +/- C. erythrophloia (red bloodwood) +/- Eucalyptus cullenii (Cullen's ironbark) +/- E. chartaboma (Queensland flaky-bark). The mixed shrub layer is open to absent and can include Gardenia vilhelmii (breadfruit), Grevillea spp., Melaleuca spp. The grassy ground cover is usually dominated by Heteropogon contortus (black speargrass) but can include Sarga plumosum (plume sorghum) and Arundinella setosa. Occurs on Tertiary remnant sandsheets. Small areas of laterisation may be present. Not a Wetland. (BVG1M: 14b). |
| Protected areas | Littleton NP, Bulleringa NP, Forty Mile Scrub NP |
| Special values | 9.5.16: Potential habitat for NCA listed species: Euphorbia carissoides. |
| 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 | 9.5.16: Occurs between Mt. Surprise and Dimbulah in the central part of bioregion. |
