Structure code Open Forest
Description Melaleuca leucadendra (weeping tea tree) +/- vine forest species, open forest to closed forest. Stream levees and prior streams on well-drained sandy clay loam alluvial soils. Riverine. (BVG1M: 22c).

Vegetation communities in this regional ecosystem include:
7.3.25a: Melaleuca leucadendra open forest and woodland. Stream levees and prior streams on well-drained sandy clay loam alluvial soils. Riverine. (BVG1M: 22c).
7.3.25b: Melaleuca leucadendra and Eucalyptus tereticornis, layered open forest, and closed forest with a vine forest understorey. Stream levees and prior streams on well-drained sandy clay loam alluvial soils. Riverine. (BVG1M: 22c).
7.3.25c: Closed forest of Tristaniopsis exiliflora and Xanthostemon chrysanthus. Stream banks, on well drained alluvium adjacent to Pleistocene sand dunes. Riverine. (BVG1M: 22c).

Special values 7.3.25: Important wildlife corridors in cleared landscapes.
Fire management guidelines SEASON: Early to mid-dry season. b,c: Do not burn deliberately. INTENSITY: Low with occasional moderate. b,c: Do not burn deliberately. INTERVAL: 3-10 years. b,c: Do not burn deliberately. INTERVAL_MIN: 3. INTERVAL_MAX: 100. STRATEGY: Burn with anticipated rain as it will increase patchiness. Create burn mosaics using progressive burning. Do not deliberately burn submerged swamps but allow fire to carry into their edge. b,c: Do not burn deliberately. Limit fire encroachment from adjacent ecosystems by burning when conditions are favourable. Burn away from edges. ISSUES: Avoid peat fires and maintain awareness of high biomass grasses which can increase fire intensity and spread. Avoid burning ant plants. b,c: Most plant species in this ecosystem are fire sensitive. Inappropriate fire may affect sensitive trees (e.g., coastal she-oaks), remove habitat trees, remove structurally complex understorey or promote weed invasion and erosion.
Comments 7.3.25: Subject to widespread weed invasion and clearing for agriculture. Distributed across the entire bioregion.
