| Description | Corymbia intermedia, Eucalyptus tereticornis grassy open forest to woodland. Other species can include Lophostemon suaveolens, Angophora leiocarpa, Eucalyptus acmenoides or E. portuensis, E. siderophloia or E. crebra, Corymbia tessellaris and Melaleuca quinquenervia (lower slopes). Eucalyptus exserta is usually present in northern parts of bioregion. Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments. Usually deep red soils. Not a Wetland. (BVG1M: 9g). Vegetation communities in this regional ecosystem include: 12.5.2a: Corymbia intermedia, Eucalyptus tereticornis woodland. Other species can include Lophostemon suaveolens, Angophora leiocarpa, Eucalyptus acmenoides or E. portuensis, E. siderophloia or E. crebra, Corymbia tessellaris and Melaleuca quinquenervia (lower slopes). Eucalyptus exserta is usually present in northern parts of bioregion. Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments usually in coastal areas with deep red soils. Not a Wetland. (BVG1M: 9g). 12.5.2b: Eucalyptus tereticornis +/- Corymbia intermedia, Lophostemon suaveolens and C. citriodora subsp. variegata open forest. Other species can include Angophora leiocarpa, Eucalyptus acmenoides, E. crebra and Corymbia tessellaris. Eucalyptus exserta is usually present in northern parts of bioregion. Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments in sub-coastal areas. Usually deep red soils. Not a Wetland. (BVG1M: 9g). 12.5.2x1: Melaleuca irbyana low open forest with emergent Eucalyptus tereticornis. Occurs on remnant Tertiary surfaces, mainly deeply weathered high level Tertiary alluvium. Palustrine.

| Special values | 12.5.2: Potential habitat for NCA listed species: Samadera bidwillii. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.2a: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.2b: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.2x1: Habitat for listed plant species Melaleuca irbyana. 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. |
| Comments | 12.5.2: Areas of this vegetation >2ha in size occurring on Cainozoic to Proterozoic sediments are mapped as the lower slope component of 12.9-10.4. Coastal and sub coastal areas. Has been extensively cleared for horticulture, sugar cane and urban development. 12.5.2a: Areas of this vegetation >2ha in size occurring on Cainozoic to Proterozoic sediments are mapped as the lower slope component of 12.9-10.4. Coastal areas. Has been extensively cleared for horticulture, sugar cane and urban development. 12.5.2b: Sub-coastal areas. Has been extensively cleared for horticulture and grazing. 12.5.2x1: This floristic association on land zone 9-10 is mapped as 12.9-10.11 and on land zone 3 is mapped as 12.3.3c. Restricted to one location south of Toogoolawah. Mostly cleared for pasture. |
