Fraser Coast Regional ecosystem information

Regional Ecosystem   12.11.5

 

Priority   4

Short Description  Corymbia citriodora subsp. variegata, Eucalyptus siderophloia, E. major open forest on metamorphics +/- interbedded volcanics

Notes  koala

Comments  12.11.5: Species composition of canopy can be very mixed, for example in the D'Aguilar Range north-west of Brisbane 10-12 tree species have been recorded in 0.1 ha plots. Occurs in moister habitats than the related RE 12.11.6. Lower altitude occurrences in south of bioregion are being extensively cleared and fragmented. D'Aguilar Range north-west of Brisbane. 12.11.5a: Lower altitude occurrences in south of bioregion are being extensively cleared and fragmented. 12.11.5e: D'Aguilar Range north-west of Brisbane. Lower altitude occurrences in south of bioregion are being extensively cleared and fragmented. Species composition of canopy can be very mixed, for example in the D'Aguilar Range north-west of Brisbane 10-12 tree species have been recorded in 0.1 ha plots. Occurs in moister habitats than the related RE 12.11.6. 12.11.5h: Restricted to the south and east of Brisbane. Cleared and fragmented. Patches often too small to map at 1:100 000. 12.11.5j: Low-altitude near coastal metamorphosed sediments generally from Brisbane to the Gold Coast. Often occurs adjacent to 12.11.23. Extensively cleared and fragmented due to urban development. 12.11.5k: Commonly found on low hills, hills and footslopes of mountains between Morayfield and the New South Wales border. 12.11.5l: Restricted to the Chermside Hills area on the north side of Brisbane City Subject to over burning (frequent fire favours fire-tolerant species at the expense of fire-sensitive species) 12.11.5m: Typically on chert bands within the D'Aguilar Range north-west of Brisbane.

Special Values  Habitat for threatened plant species including Cycas megacarpa and Sophora fraseri. 12.11.5a: Habitat for threatened flora species including Sophora fraseri. 12.11.5e: Habitat for threatened flora species including Cycas megacarpa and Sophora fraseri. 12.11.5h: Habitat for threatened flora species including Sophora fraseri. 12.11.5j: Habitat for threatened flora species including Sophora fraseri. 12.11.5k: Habitat for threatened flora species including Sophora fraseri.

Lophostemon confertus often present in gullies and as a sub-canopy or understorey tree. Mixed understorey of grasses, shrubs and ferns. Occurs on hills and ranges of Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics.
