| Short description | Acacia shirleyi woodland on lateritic knolls |
| Structure code | Open Forest |
| Description | Acacia shirleyi woodland to open forest commonly with Corymbia stockeri or C. clarksoniana scattered in the canopy. Scattered A. shirleyi, Larsenaikia ochreata or Melaleuca stenostachya can occur in the very sparse subcanopy. The very sparse to sparse shrub layer can contain canopy species with Petalostigma banksii and Carissa spp. also common. The very sparse ground layer can contain Eragrostis spp., Cleistochloa spp., Digitaria spp. And Schoenus sparteus. Occurs on rocky knolls of lateritised quartzose sandstone. Not a Wetland. (BVG1M: 24a). |

| Protected areas | Olkola NP (CYPAL) |
| Special values | 3.7.2: The vegetation community 3.10.6x1a was amalgamated into this RE. North-easternmost extension of this ecosystem, which is widespread in Queensland and parts of the Northern Territory. |
| Fire management guidelines | SEASON: Dry season but avoid periods of extremely hot, dry conditions. INTENSITY: Low, with occasional moderate to high. INTERVAL: 10+ years for lancewood communities. INTERVAL_MIN: 10. INTERVAL_MAX: 50. STRATEGY: Typically self protecting due to low fuel loads and position in the landscape. ISSUES: Fires typically trickle through these vegetation communities because fuel is insufficiently available. |
| Comments | 3.7.2: Occurs in small patches. Restricted to south of bioregion. |
