| Regional ecosystem | 9.11.16 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 2, 1, (5), (2.9) |
| Estimated extent1 | Pre-clearing 312000 ha; Remnant 2021 312000 ha |
| Short description | Eucalyptus crebra +/- Corymbia erythrophloia or C. pocillum woodland on steep to rolling hills |
| Structure code | Woodland |
| Description | Woodland to open woodland of Eucalyptus crebra (narrow-leaved ironbark) +/- Corymbia erythrophloia (red bloodwood) or C. pocillum +/- Corymbia spp. A sub-canopy layer of canopy species, Terminalia aridicola (arid peach) and/or Erythroxylum ellipticum (kerosene wood) may be present. The shrub layer varies from isolated plants to mid-dense and can include Denhamia cunninghamii (yellowberry bush), Vachellia bidwillii (corkwood wattle), Petalostigma spp., Erythrophleum chlorostachys (Cooktown ironwood), Bursaria incana (prickly pine) and other Acacia spp. The ground layer is grassy and dominated by Themeda triandra (kangaroo grass) and/or Heteropogon contortus (black speargrass). Occurs on red to brown soils derived from metamorphic geologies on steep to rolling hills. Not a Wetland. (BVG1M: 13c). |

| Protected areas | Blackbraes NP, Rungulla NP, Rungulla RR, Kennedy Road Gravel RR |
| Special values | 9.11.16: Potential habitat for NCA listed species: Labichea brassii, Macropteranthes montana. |
| 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 | 9.11.16: Distinguished from 9.11.15a by being on steeper, more dissected hills. Distinguished from 9.11.15b by absence of Eucalyptus microneura. Occurs from Cobbold Gorge to Oak Park in the west of the bioregion. |
