Regional ecosystem details for 9.12.15
| Regional ecosystem | 9.12.15 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 2, 3, (3.1) |
| Estimated extent1 | Pre-clearing 41000 ha; Remnant 2021 41000 ha |
| Short description | Eucalyptus staigeriana +/- Erythrophleum chlorostachys low open woodland on hills on igneous rocks |
| Structure code | Low Open Woodland |
| Description | Low open woodland to low woodland of Eucalyptus staigeriana (lemon-scented ironbark) +/- Erythrophleum chlorostachys (Cooktown ironwood) +/- Eucalyptus cullenii (Cullen's ironbark) +/- Terminalia spp. +/- Corymbia erythrophloia (red bloodwood) or C. hylandii (Hyland's bloodwood). There is a sparse to mid-dense shrub layer of Petalostigma banksii (smooth-leaved quinine), Grevillea spp. and occasionally Xanthorrhoea johnsonii (grass-tree). The ground layer is dominated by Heteropogon spp. (speargrass), Themeda triandra (kangaroo grass) and Schizachyrium fragile (firegrass). Occurs on hills with acid igneous geology. Not a Wetland. (BVG1M: 13a). |
| Special values | 9.12.15: 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 | 9.12.15: Patches of 9.12.36 can occur around rocky outcrops within 9.12.15. Occurs from the Featherbed Range to Maitland Downs in the north of the bioregion. |
