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).

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.
