| Description | Semi-evergreen vine thicket. Canopy species include Flindersia australis, Flindersia collina, Alstonia constricta, Excoecaria dallachyana, Geijera parviflora, Notelaea spp., Planchonella cotinifolia var. pubescens, Diospyros humilis and Denhamia oleaster, with emergent Brachychiton rupestris or Flindersia australis. A dense shrub layer of Psydrax odorata and Acalypha eremorum commonly occurs. May contain emergent Eucalyptus decorticans or Eucalyptus melanoleuca in some southern locations. Occurs on remnant Tertiary surfaces. Deep red and yellow earths. Not a Wetland. (BVG1M: 7a). |

| Protected areas | Bania NP, Gurgeena CP, Reinke Scrub CP, Newport CP |
| Special values | 11.5.15: Habitat for threatened plant species including Fontainea fugax, Pomaderris clivicola and Cadellia pentastylis and the near threatened species Macropteranthes leiocaulis; a wide range of flora and fauna species with disjunct distributions. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Grazing may be useful in managing fuel loads created by introduced grasses such as buffel. |
| Comments | 11.5.15: Mapped areas sometimes include small areas eroded scarp slopes or areas of duricrust (land zone 7). If these areas are large enough (> 5ha) they are mapped as 11.7.1x1. Cleared for pasture. |
1 Estimated extent is from version 13 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.
