| Subregion | 7, 9, (8), (4) |
| Estimated extent1 | Pre-clearing 18000 ha; Remnant 2021 4000 ha |
| Short description | Eucalyptus cloeziana open forest on metamorphics +/- interbedded volcanics |
| Structure code | Open Forest |
| Description | Eucalyptus cloeziana +/- E. propinqua, E. acmenoides, E. microcorys and E. grandis open forest. Understory is generally shrubby +/- vine forest species. Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics, especially phyllite of the Kin Kin Beds. Not a Wetland. (BVG1M: 8b). Vegetation communities in this regional ecosystem include: 12.11.16x1: [RE not in use]²: This regional ecosystem is now mapped as 12.9-10.29. Eucalyptus cloeziana +/- E. propinqua, E. acmenoides, E. microcorys and E. grandis tall open forest. Occurs on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 8a). |

| Protected areas | Gympie NP, Goomboorian NP, Tewantin NP, Six Mile Creek CP, Woondum NP |
| Special values | 12.11.16: Potential habitat for NCA listed species: Samadera bidwillii, Triunia robusta and Xanthostemon oppositifolius. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Plan for low to moderate. Unplanned occasional high intensity wildfire will occur. INTERVAL: 4-8 years maintains a healthy grassy system. 8-20 years for shrubby elements of understorey. INTERVAL_MIN: 4. INTERVAL_MAX: 20. STRATEGY: Aim for 40-60% mosaic burn. Needs disturbance to maintain RE structure (eucalypt overstorey with open understorey of predominantly non-rainforest species). ISSUES: Frequent fire is needed to maintain understorey integrity, keeping more mesic species low in the profile of the understorey so that other species can compete. It is essential that wildfires are not the sole source of fire in this ecosystem. High intensity fires occur periodically through time, however frequent low to moderate intensity fires will create the disturbance required to keep the understorey diverse. A follow-up burn soon after a high intensity wildfire can be considered to reduce resprouting or germinating mesic species. |
| Comments | 12.11.16: Eucalyptus cloeziana has a markedly disjunct distribution in eastern Queensland. Eucalyptus cloeziana has potential as a very adaptable plantation hardwood species. Can develop an understorey of vine forest species in the absence of fire. Areas outside of state forest mostly cleared for agriculture. 12.11.16x1: Erected as new RE 12.9-10.29 in August 2016. Eucalyptus cloeziana has potential as a very adaptable plantation hardwood species. Eucalyptus cloeziana has a markedly disjunct distribution in eastern Queensland. Areas outside of state forest mostly cleared for agriculture. |
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.
