Description Shrubby woodland complex. More widely distributed and abundant species include Corymbia trachyphloia subsp. trachyphloia, C. citriodora subsp. variegata, Eucalyptus crebra, E. fibrosa subsp. fibrosa, E. major, Angophora leiocarpa, E. helidonica. Understorey of sclerophyllous shrubs. Localised occurrences of Eucalyptus baileyana, E. pilularis, Corymbia henryi, E. dura, E. decorticans (extreme west of bioregion), E. taurina, Angophora woodsiana, Lysicarpus angustifolius and Lophostemon confertus. Tends to shrubland or monospecific woodland of species such as Eucalyptus dura on shallow lithosols. Occurs on quartzose sandstone scarps and crests. Not a Wetland. (BVG1M: 9h).

Vegetation communities in this regional ecosystem include:

Special values 12.9-10.5: Habitat for threatened plant species including Leucopogon recurvisepalus, Paspalidium grandispiculatum, Leionema obtusifolium and near threatened species including Eucalyptus curtisii. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.5a: Habitat for threatened plant species including Eucalyptus taurina, Caustis blakei subsp. macrantha, Paspalidium grandispiculatum, Leionema obtusifolium and Grevillea quadricauda. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.9-10.5b: Habitat for threatened flora species including Paspalidium grandispiculatum. 12.9-10.5d: 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. INTERVAL_MIN: 7. INTERVAL_MAX: 25. 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 and intensity should be such as to allow obligate seeders to reach maturity and produce viable seed.
Comments 12.9-10.5a: Helidon hills region. 12.9-10.5b: Erected as the new RE 12.9-10.25 in August 2016. Tarong area. 12.9-10.5c: Erected as the new RE 12.9-10.26 in August 2016. Eucalyptus psammitica dominated areas mainly occur in Toohey Forest. 12.9-10.5d: Restricted to the far south of the Southeast Queensland bioregion.

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.

2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
