| Short description | Acacia shirleyi +/- Corymbia pocillum +/- Eucalyptus microneura woodland on igneous rocks |
| Structure code | Woodland |
| Description | Woodland to low woodland of Acacia shirleyi (lancewood) +/- Corymbia pocillum +/- Eucalyptus microneura (Georgetown box). Isolated emergents of A. shirleyi can also occur. The shrub layer ranges from absent to open and can include A. shirleyi, Petalostigma banksii (smooth-leaved quinine), Gardenia vilhelmii (breadfruit) and Melaleuca spp. The sparse grassy ground layer is and dominated by Schizachyrium spp. (firegrass) The subdominants species occur only occasionally. Occurs on shallow soils on rocky outcrops of igneous hills. Not a Wetland. (BVG1M: 24a). |

| Fire management guidelines | INTERVAL: 10-50 years generally following periods of high rainfall and sufficient grass growth. INTERVAL_MIN: 10. INTERVAL_MAX: 50. STRATEGY: Maintain fire management of surrounding country so that wildfires will be very limited in extent and do not penetrate Lancewood forests. ISSUES: Although fire promotes the germination of Lancewood seedlings, trees are killed by all but the lowest intensity fires. Lancewood trees typically require approximately 20 years before seedlings mature. Often the lack of grass layer inhibits fire spread into these forests, and they will regenerate after occasional wildfires. Damaged by repeated fires < 20 years. Manage surrounding woodlands so that wildfires do not burn large areas of Lancewood forest in a single event. |
| Comments | 9.12.37: Occur close to the Gulf Plains boundary from Croydon to Bolwarra in the north west of the bioregion. |
