Fraser Coast Regional ecosystem information

Regional Ecosystem   12.9-10.4


Priority   3

Short Description  Eucalyptus racemosa subsp. racemosa woodland on sedimentary rocks

Notes  koala

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. The RE has been extensively cleared and fragmented in lowland areas. Coastal lowlands and some sub coastal outliers around Esk and west of Maryborough. 12.9-10.4a: 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. Connected to groundwater.

Special Values  Habitat for threatened plant species including Macrozamia pauli-guilielmi and Acacia attenuata.

Fraser Coast region distribution  Patches mapped in south-east of region in Toolara Forest, Tuan Forest and Tin Can bay. Inland patches mapped in central-south of region at Thinoomba, St Mary, Woocoo and Glenbar.

Long Description  Open forest to woodland with Eucalyptus racemosa subsp. racemosa locally prominent. Other species can include Angophora leiocarpa, Eucalyptus seeana, E. siderophloia, Corymbia intermedia, E. tindaliae with Lophostemon suaveolens, Melaleuca quinquenervia, E. tereticornis on lower slopes. Occurs on Cainozoic and Mesozoic sediments +/- remnant Tertiary surfaces. (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 var. laterale and other sedges and grasses. Other canopy species can include Corymbia gummifera, C. intermedia, C. trachyphloia subsp. Trachyphloia, 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 wetland (e.g. vegetated swamp). (BVG1M: 9g)
