| Regional ecosystem | 12.11.23 |
|---|---|
| Vegetation Management Act class | Endangered |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 3, 4 |
| Estimated extent1 | Pre-clearing 9000 ha; Remnant 2021 2000 ha |
| Short description | Eucalyptus pilularis open forest on coastal metamorphics and interbedded volcanics |
| Structure code | Open Forest |
| Description | Eucalyptus pilularis open forest. Other canopy species include E. microcorys, Corymbia intermedia, Angophora woodsiana, E. tindaliae and E. carnea. E. racemosa subsp. racemosa and Corymbia trachyphloia are prominent in the Venman area whilst C. gummifera and E. resinifera are prominent in the Nerang area. Occurs on low coastal Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics (Neranleigh-Fernvale beds). Not a Wetland. (BVG1M: 8b). |

| Special values | 12.11.23: 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: High fuel loads develop within a short period of time owing to bark drop. High intensity fires occur periodically through time, however frequent low to moderate intensity fires will create the disturbance required to keep the understorey diverse. Mesic species are likely regenerate from resprout. |
| Comments | 12.11.23: Tends to grade downslope into 12.11.27 (E. racemosa/ E. seeana) or land zone 3. Restricted to coastal metasediments (Neranleigh-Fernvale beds) from Logan south to the New South Wales border. Extensively cleared and fragmented by urban development. |
