| Regional ecosystem | 11.12.17 |
|---|---|
| Vegetation Management Act class | Endangered |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |

| Short description | Eucalyptus populnea woodland on igneous rocks. Colluvial lower slopes |
| Structure code | Woodland |
| Description | Eucalyptus populnea woodland with Eremophila mitchellii dominated mid layer. In northern areas, there may be subdominant Corymbia dallachiana or Eucalyptus platyphylla. Occurs on colluvial lower slopes formed on Mesozoic to Proterozoic igneous rocks. Typical soils are deep texture-contrast soils with strongly alkaline subsoils. Not a Wetland. (BVG1M: 17a). |

| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 6-15 years. INTERVAL_MIN: 6. INTERVAL_MAX: 15. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. All shrubby areas will carry fire after a good season. ISSUES: Management of this fire tolerant vegetation type should be based on maintaining vegetation composition, structural diversity, animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of habitat and mitigate against wildfires. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.12.17: Particularly prevalent on soils derived from andesites. |
