| Structure code | Open Forest |
| Description | Eucalyptus montivaga open forest to woodland. Other canopy species can include Eucalyptus acmenoides, Corymbia trachyphloia, C. gummifera, Syncarpia glomulifera subsp. glomulifera and C. intermedia. Occurs on Mesozoic to Proterozoic igneous rocks. Altitude >500 m. Not a Wetland. (BVG1M: 8b). Vegetation communities in this regional ecosystem include: 12.12.6x1: [RE not in use]²: This regional ecosystem is now mapped as 12.11.9x1 as it occurs on land zone 11. Eucalyptus montivaga open forest. Other canopy species can include Corymbia trachyphloia, E. acmenoides, Syncarpia glomulifera subsp. Glomulifera and C. intermedia. Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Altitude >500m. Not a Wetland. (BVG1M: 8b). |

| Special values | 12.12.6: Habitat for threatened plant species including Daviesia discolor. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). 12.12.6x1: Habitat for threatened flora species including Daviesia discolor and near threatened species including Acomis acoma. |
| 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 should be such as to allow obligate seeders to reach maturity and produce viable seed. |
| Comments | 12.12.6: A vegetation type commonly associated with cooler topographic isolates throughout the bioregion and patches sometimes too small to map. Over-frequent fire can promote fire-tolerant understorey species, such as blady grass, at the expense of shrubs. |
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.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
