| Short description | Sedgeland and/or open heathland with small areas of eucalypt woodland on alluvial deposits in igneous landscapes |
| Structure code | Open Heath |
| Description | Sedgeland and/or open heathland, occasional with fringing eucalyptus woodlands. Occurs along small drainage lines and soaks at high altitude on Mesozoic to Proterozoic igneous rocks. Palustrine. (BVG1M: 34f). Vegetation communities in this regional ecosystem include: 13.3.6a: Eucalyptus camphora subsp. camphora mallee woodland/tall shrubland or fringing woodland with a sedgy understorey. Occurs along small drainage lines and soaks at high altitude on Mesozoic to Proterozoic igneous rocks. Palustrine. (BVG1M: 34f). 13.3.6b: Melaleuca thymifolia heath on gritty siliceous seepage areas. Occurs along small drainage lines and soaks at high altitude on Mesozoic to Proterozoic igneous rocks. Palustrine. (BVG1M: 29b). |

| Protected areas | Girraween NP |
| Special values | 13.3.6: Northern limit of the temperate adapted species Eucalyptus camphora and Olearia glandulosa. Provides wetland habitat for a range of flora and fauna. 13.3.6a: Northern limit of the temperate adapted species Eucalyptus camphora and Olearia glandulosa. Provides wetland habitat for a range of flora and fauna. 13.3.6b: Northern limit of the temperate adapted species Eucalyptus camphora and Olearia glandulosa. Provides wetland habitat for a range of flora and fauna. |
| Fire management guidelines | SEASON: Autumn/Winter (Apr-Aug). INTENSITY: Low. INTERVAL: 5-12 years. INTERVAL_MIN: 5. INTERVAL_MAX: 12. STRATEGY: Burn < 20% of stands in any year, burning patches each year whenever possible. ISSUES: Loss of vegetation complexity occurs in this ecosystem if (1) unburnt for many years, leading to senescence of sedges or (2) burnt too frequently. |
| Comments | 13.3.6: Described in Sattler and Williams under 13.12.7 but has been reallocated to the correct land zone. A rare regional ecosystem. Subject to pig damage and Andropogon virginicus infestation. 13.3.6a: Described in Sattler and Williams under 13.12.7 but has been reallocated to the correct land zone. A rare regional ecosystem. Subject to pig damage and Andropogon virginicus infestation. 13.3.6b: Described in Sattler and Williams under 13.12.7 but has been reallocated to the correct land zone. A rare regional ecosystem. Some areas are too small to map. 13.3.6a and 13.3.6b wholly contained within Girraween National Park. Subject to pig damage and Andropogon virginicus infestation. |
