| Short description | Eucalyptus racemosa subsp. racemosa woodland on remnant Tertiary surfaces |
| Structure code | Woodland |
| Description | Eucalyptus racemosa subsp. racemosa woodland with Corymbia intermedia, E. siderophloia +/- E. tindaliae, E. resinifera, E. pilularis, E. microcorys, Angophora leiocarpa. Melaleuca quinquenervia is often a prominent feature of lower slopes. Minor patches (<1ha) dominated by Corymbia citriodora subsp. variegata sometimes occur. Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9g). Vegetation communities in this regional ecosystem include: 12.5.3a: Mixed woodland to open forest usually containing Corymbia intermedia, Eucalyptus racemosa subsp. racemosa and at least a presence of Eucalyptus seeana. Other commonly associated species include Angophora leiocarpa, E. siderophloia, E. microcorys, C. citriodora subsp. variegata and Lophostemon suaveolens. Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9g). |

| Special values | 12.5.3: Potential habitat for NCA listed species: Allocasuarina emuina, Eucalyptus curtisii, Leptospermum oreophilum. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.5.3a: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Low to moderate. INTERVAL: 7-10 years. INTERVAL_MIN: 7. INTERVAL_MAX: 10. STRATEGY: Aim for a burn mosaic of 40-60% over the burn area. A diversity of season and fire intensity is important, as well as spot ignition in cooler or moister periods to encourage mosaics. Late summer burns assist with maintaining control of fire intensity. ISSUES: Avoid repeated low intensity fires. Fires that are too frequent will eliminate obligate seeding species. Fire frequency should be such as to allow obligate seeders to reach maturity and produce viable seed. |
| Comments | 12.5.3: Patches of this vegetation >2ha in size occurring on Cainozoic and Mesozoic sediments sediments are defined as 12.9-10.4. Occurs from Noosa southward. Extensively cleared for exotic pine plantation, horticulture and urban development. 12.5.3a: Eucalyptus seeana is often only a minor component of this Regional ecosystem. Areas of this floristic association on Cainozoic to Proterozoic sediments that are mappable (>2ha) are defined as 12.9-10.12. Occurs mainly to the south of Brisbane. Extensively cleared for urban development. |
