| Biodiversity status | No concern at present |
| Subregion | 4, (10.2), (10.3) |
| Estimated extent1 | Pre-clearing 29000 ha; Remnant 2021 27000 ha |
| Short description | Eucalyptus quadricostata +/- Corymbia erythrophloia +/- C. leichhardtii open woodland on metamorphic hills and ranges |
| Structure code | Open Woodland |
| Description | Open woodland to woodland of Eucalyptus quadricostata (square-fruited ironbark) +/- Corymbia erythrophloia (red bloodwood) +/- C. leichhardtii (yellowjacket) +/- C. lamprophylla (shiny-leaved bloodwood). A sparse sub-canopy layer can occur and include canopy species, Bursaria incana (prickly pine) and Grevillea spp. The shrub layer varies from absent to sparse and includes juvenile canopy species, Denhamia cunninghamii (yellowberry bush), B. incana, Grevillea spp., Acacia spp., and Xanthorrhoea johnsonii (grasstree). There is a sparse mixed grassy ground layer which can include Heteropogon contortus (black speargrass), Enneapogon spp. and Triodia spp. (spinifex). Occurs on gravelly soils on hills and steep hills. Not a Wetland. (BVG1M: 13a). |

| 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 | 9.11.18: Restricted to hills north of the White Mountains NP in the south of the bioregion. Subject to minor clearing. |
