| Short description | Terminalia aridicola subsp. chillagoensis and T. platyphylla low open woodland on clay soils |
| Structure code | Open Woodland |
| Description | Terminalia aridicola subsp. chillagoensis (arid peach) and T. platyphylla (black plum) low open woodland to low woodland. Scattered emergent Bombax ceiba may occur. The subcanopy is generally absent. The very sparse to sparse shrub layer usually contains Grewia savannicola (dog's balls), Antidesma spp. And Dendrolobium umbellatum. The mid-dense to dense ground layer is dominated by the grasses Themeda arguens, Heteropogon contortus (black speargrass) and Desmodium spp., Scleria spp., and Fimbristylis spp. Occurs on heavy clay. Contains Palustrine. (BVG1M: 27a). |

| Fire management guidelines | SEASON: Progressive early to mid-dry season, followed by storm time burns. INTENSITY: Moderate to high. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn when fires will carry, which is generally Sep to Oct. Begin burning early in the fire season, followed by progressive patch fires burnt through the year. Burn up to 50% in any year. ISSUES: Patch burning should aim to create a mosaic of burnt and unburnt patches in order to impede wildfire. Storm burning can be used to promote perennial grasses and prevent vegetation thickening. Reduction in cattle grazing may be required to produce adequate fire intensity. Thickening up of some patches could be due to a decreased fire frequency. |
| Comments | 3.9.6: Occurs in the vicinity of Laura to Lakefield. More intensive cattle grazing probable in the future. Thickening up of some patches has occurred, probably due to a decreased fire frequency. |
