| Regional ecosystem | 12.12.9 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |

| Short description | Eucalyptus dura woodland usually on rocky peaks on Mesozoic to Proterozoic igneous rocks |
| Structure code | Woodland |
| Description | Eucalyptus dura woodland (open woodland in rocky areas) +/- Corymbia trachyphloia subsp. trachyphloia, E. acmenoides or E. portuensis, Acacia blakei subsp. blakei, Allocasuarina littoralis, C. intermedia. Eucalyptus montivaga may also be present at higher altitudes. Lophostemon confertus (whipstick form) often present in shrub layer. Usually occurs on Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 12a). |
| Supplementary description | Bean et al. (1998), J16 (in part) |
| Protected areas | Mount Walsh NP, Castle Tower NP, Beninbi NP, Crows Nest NP, Dawes NP, Eurimbula NP |
| Special values | 12.12.9: Habitat for threatened plant species including Cassinia collina and near threatened species including Acacia pubicosta and Comesperma breviflorum. 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. May be difficult to burn due to sparsity of grasses. |
| Comments | 12.12.9: Frequent fire can favour fire-tolerant species at the expense of fire-sensitive species. |
