| Short description | Eucalyptus racemosa subsp. racemosa woodland on sedimentary rocks |
| Structure code | Woodland |
| Description | Eucalyptus racemosa subsp. racemosa woodland to open forest. Other species can include Angophora leiocarpa, Eucalyptus seeana, E. siderophloia, Corymbia intermedia, E. tindaliae, with Lophostemon suaveolens, Melaleuca quinquenervia, E. tereticornis common on lower slopes. Occurs on Cainozoic and Mesozoic sediments +/- remnant Tertiary surfaces. Not a Wetland. (BVG1M: 9g). Vegetation communities in this regional ecosystem include: 12.9-10.4a: Eucalyptus racemosa subsp. racemosa woodland to open woodland with a wet ground layer often dominated by Ptilothrix deusta, Lepidosperma laterale and other sedges and grasses. Other canopy species can include Corymbia gummifera, C. intermedia, Melaleuca quinquenervia, Lophostemon suaveolens and Eucalyptus resinifera. A secondary tree layer of Melaleuca quinquenervia, Lophostemon suaveolens, Allocasuarina littoralis may also be present. Occurs on moist lower slopes and discharge areas on Cainozoic and Mesozoic sediments +/- remnant Tertiary surfaces. Palustrine. (BVG1M: 9g). |

| Special values | 12.9-10.4: Habitat for threatened plant species including Macrozamia pauli-guilielmi and Acacia attenuata. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.4a: This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. |
| Comments | 12.9-10.4: The inland occurrences in particular support disjunct species assemblages of conservation importance for example Grevillea banksii. Does not include areas co-dominated by Eucalyptus seeana. Patches of this vegetation association on remnant Tertiary surfaces that are larger than 2 ha are defined as 12.5.3. Coastal lowlands and some sub coastal outliers around Esk and west of Maryborough. The RE has been extensively cleared and fragmented in lowland areas. 12.9-10.4a: Connected to groundwater. Restricted to areas of groundwater discharge from sedimentary rocks. Known locations are the J. C. Trotter Memorial Park and Karawatha Forest. Historically cleared for pasture production but now mostly contained within Brisbane City Council protected area estate. Hot or frequent fires have removed or thinned canopy species especially at J. C. Trotter Memorial Park. |
