| Regional ecosystem | 12.3.18 |
|---|---|
| Vegetation Management Act class | Endangered |

| Estimated extent1 | Pre-clearing 2000 ha; Remnant 2021 100 ha |
| Short description | Melaleuca irbyana low open forest on alluvial plains |
| Structure code | Low Open Forest |
| Description | Melaleuca irbyana low open forest or thicket. Emergent Eucalyptus moluccana, E. crebra, E. tereticornis or Corymbia citriodora subsp. variegata may be present. Occurs on Quaternary alluvial plains where drainage of soils is impeded. Palustrine. (BVG1M: 21b). |
| Supplementary description | Bean et al. (1998), C5 |
| Special values | 12.3.18: Habitat for listed plant species Melaleuca irbyana and Marsdenia coronata. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to late-autumn. INTENSITY: Low. INTERVAL: 3-6 years. INTERVAL_MIN: 3. INTERVAL_MAX: 6. STRATEGY: Aim to burn 40-60% of any given area. Spot ignition in cooler or moister periods encourages mosaics. ISSUES: Maintain ground litter and fallen timber habitats by burning only with sufficient soil moisture. Burning should aim to produce fine scale mosaics of unburnt areas. May be difficult to burn due to solodic soil with sparse vegetation. |
| Comments | 12.3.18: Previously mapped as 12.3.3c. This floristic association on land zone 9-10 is mapped as 12.9-10.11. Restricted to the Ipswich and Jimboomba regions and the Lockyer and Fassifern Valleys. |
