| Short description | Macropteranthes leichhardtii thicket on Cainozoic igneous rocks |
| Structure code | Low Closed Forest |
| Description | Macropteranthes leichhardtii thicket. Usually forms a dense community of Macropteranthes leichhardtii with occasional or subdominant Geijera parviflora, Croton insularis and Acacia fasciculifera with an emergent layer of Brachychiton rupestris or B. australis or Acacia harpophylla. A dense shrub layer may include Capparis anomala, Ehretia membranifolia, Croton phebalioides, Erythroxylum australe or Carissa ovata. Occurs on steep hills on Cainozoic igneous rocks, on skeletal soils and shallow brown to black loams, often with large boulders at the soil surface. Not a Wetland. (BVG1M: 7a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Grazing may be useful in managing fuel loads created by introduced grasses such as buffel. |
