| Vegetation Management Act class | Of concern |

| Short description | Corymbia setosa +/- Eucalyptus crebra low open woodland on metamorphic hills |
| Structure code | Low Open Woodland |
| Description | Woodland to low open woodland of Corymbia setosa (rough-leaved bloodwood) +/- Eucalyptus crebra (narrow-leaved ironbark) +/- C. clarksoniana (Clarkson's bloodwood) +/- Melaleuca nervosa (woodland paperbark) +/- C. peltata (rustyjacket). C. clarksoniana and/or E. crebra can also occur as emergents. An open sub-canopy layer can occur and include canopy species, Petalostigma pubescens (quinine) and Grevillea glauca (bushman's clothes peg). The open to mid-dense shrub layer includes M. nervosa, Petalostigma spp., Denhamia cunninghamii (yellowberry bush) and Alphitonia spp. The grassy ground layer is dominated by Heteropogon contortus (black speargrass) and Aristida spp. Occurs on low hills to 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 | 9.11.21: Occurs on low hills south of Lynd Junction in the south of the bioregion. Vulnerable to invasion of exotic weeds Vachellia farnesiana (mimosa) and Melinis repens (Red Natal grass). |
