| Short description | Eucalyptus moluccana open forest on sedimentary rocks |
| Structure code | Open Forest |
| Description | Eucalyptus moluccana open forest. Other canopy species include Eucalyptus siderophloia or E. crebra, E. tereticornis and Corymbia citriodora subsp. variegata. Understorey generally sparse but can become shrubby in absence of fire. Occurs on Cainozoic and Mesozoic sediments, especially shales. Prefers lower slopes. Not a Wetland. (BVG1M: 13d). |

| Special values | 12.9-10.3: Potential habitat for NCA listed species: Callitris baileyi, Haloragis exalata subsp. velutina, Picris conyzoides, Sophora fraseri. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. Control of lantana with fire might be required. Occurrence of khaki weed Alternathera pungens is unrelated to fire and due to grazing pressure. There is evidence that the spiral leaf Macrozamias (e.g. M. parcifolia) decline in health if fire interval is greater than 6 years. |
| Comments | 12.9-10.3: Extensively cleared or thinned for grazing. |
