| Regional ecosystem | 12.8.27 |
|---|---|
| Vegetation Management Act class | Endangered |
| Wetlands | Not a Wetland |

| Estimated extent1 | Pre-clearing 20 ha; Remnant 2021 0 ha |
| Short description | Dichanthium spp. and Themeda triandra grassland on igneous rocks |
| Structure code | Tussock Grassland |
| Description | Grassland of Bothriochloa bladhii, Themeda triandra, Dichanthium sericeum +/- Bothriochloa biloba. Small stands of Eucalyptus melanophloia or Corymbia tessellaris may occur throughout. Occurs on undulating low hills consisting of heavy black clay soil derived from basalt. Not a Wetland.

| Fire management guidelines | SEASON: Spring (after rainfall). INTENSITY: Low. INTERVAL: 7-20 years. INTERVAL_MIN: 7. INTERVAL_MAX: 20. STRATEGY: Burn after recent rainfall when soil moisture is high. ISSUES: Restricted to Redbank Plains, Ipswich. Intact plant communities are probably extinct. Spring burns have an associated risk due to changing weather conditions post-burn. |
