| Short description | Lysiphyllum cunninghamii, Ventilago viminalis, Atalaya hemiglauca, Corymbia terminalis in mixed low woodlands on plains and low rises of Cretaceous mudstone |
| Structure code | Low Woodland |
| Description | Mixed low woodland, including a combination of the species Lysiphyllum cunninghamii, Ventilago viminalis, Atalaya hemiglauca, Corymbia terminalis, Owenia acidula, Denhamia oleaster and Acacia cambagei. A sparse shrub layer may occur, including canopy species Carissa lanceolata and Santalum lanceolatum. The ground layer is tussock grasses. Includes small areas of Enneapogon polyphyllus tussock grassland on exposed mudstone rocks. Occurs on plains and low rises of Cretaceous mudstone and limestone (Toolebuc Formation). Brown cracking clay soils with patches of exposed rock. Not a Wetland. (BVG1M: 27b). |
| Fire management guidelines | SEASON: Avoid the hottest seasons. INTENSITY: Moderate. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Burn less than 30% in any year. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Too frequent fire may disadvantage and reduce extent of this vegetation type. Avoid fires at the hottest time of the year, when extent of fires cannot be controlled. Low intensity fires will be useful in reducing fuel loads and fire spread in later fires. Moderate fires may assist in regeneration of hard-seeded spp. |
| Comments | 2.9.9: Previously mapped as 2.9.4x1. Commonly invaded by *Cenchrus ciliaris (buffel grass). |
