| Short description | Eucalyptus camaldulensis +/- Atalaya hemiglauca +/- Acacia georginae +/- Acacia cyperophylla var. cyperophylla woodland on alluvium |
| Structure code | Woodland |
| Description | Eucalyptus camaldulensis woodland, commonly with Acacia georginae, Acacia cyperophylla var. cyperophylla var. cyperophylla and Atalaya hemiglauca. Scattered low shrubs such as Senna artemisioides subsp. oligophylla and Eremophila freelingii may occur. The ground layer is dominated by tussock grasses. Occurs on streamlines and channels draining dissected residuals and plateaus. Soils gravelly loams to sandy clay loams. Riverine. (BVG1M: 16a). |

| Fire management guidelines | SEASON: Wet to early dry season when soil is moist. INTENSITY: Low. INTERVAL: Broad interval range of 6-10 years. There is rarely enough fuel load to burn in these ecosystems. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Patchy, within the 20-30% range of area burnt. ISSUES: Acacias (e.g., gidgee) germinate infrequently following high rainfall events, mature slowly and are long-lived. Acacias are vulnerable to frequent and high-severity fires. Fire in surrounding fire-adapted communities can be used to mitigate against wildfire. Fuel loads within Acacia communities can sometimes also require infrequent patchy burns, particularly following years of good rain, to protect them from wildfire and promote diversity at the ground layer. Long absence of fire can result in canopy closure by Acacias and lead to self-protection of these communities. Introduced invasive grasses (e.g., buffel Cenchrus ciliaris) may increase the risk and severity of fires. |
