Subregion 4, 9, 2, (3)
Estimated extent1 Pre-clearing 57000 ha; Remnant 2019 6000 ha

Short description Eucalyptus racemosa subsp. racemosa woodland on remnant Tertiary surfaces
Structure category Sparse
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. (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)
Supplementary description Ryan, T.S. (ed.) (2012); Bean et al. (1998), D8a, H14
Protected areas Glass House Mountains NP, Tewantin NP, Freshwater NP, Great Sandy NP, Cooroibah CP, Noosa NP, Sheep Station Creek CP, Pumicestone NP, Teerk Roo Ra NP (IJMA), Harry Spring CP, Springwood CP, Beerwah FR, Ningi Creek CP, Teerk Roo Ra CP (IJMA)
Special values 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: 7-25 years. 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 trees 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. Extensively cleared for exotic pine plantation, horticulture and urban development. Occurs from Noosa southward. 12.5.3a: Occurs mainly to the south of Brisbane. Extensively cleared for urban development. 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.
