| Short description | Eucalyptus crebra woodland to open woodland on deformed and metamorphosed sediments and interbedded volcanics |
| Structure code | Woodland |
| Description | Eucalyptus crebra +/- Corymbia erythrophloia +/- E. populnea +/- E. melanophloia +/- C. tessellaris +/- C. clarksoniana woodland to open woodland often with a shrubby layer. Eucalyptus exserta and E. platyphylla present in central coastal part of bioregion. Occurs on undulating rises and low hills, often with distinct strike pattern formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 13c). Vegetation communities in this regional ecosystem include: 11.11.15a: Eucalyptus crebra, E. exserta woodland. Occurs on undulating rises and low hills, often with distinct strike pattern formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 13c). 11.11.15b: Eucalyptus drepanophylla and/or E. platyphylla woodland +/- vine thicket species. Occurs on undulating rises and low hills, often with distinct strike pattern formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics and Permian sediments. Not a Wetland. (BVG1M: 13c). 11.11.15c: Woodland with Corymbia setosa present to dominant, usually with Corymbia clarksoniana, Eucalyptus melanophloia, Corymbia dallachiana and Eucalyptus crebra, with occasional shrubs of Petalostigma pubescens and Alphitonia excelsa. Occurs on rises and hills, often with distinct strike pattern formed on moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Not a Wetland. (BVG1M: 13c). 11.11.15d: Woodland with Corymbia setosa present to dominant, usually with Corymbia clarksoniana, Eucalyptus melanophloia, Corymbia dallachiana and Eucalyptus crebra, with occasional shrubs of Petalostigma pubescens and Alphitonia excelsa. Occurs on low rises and short hills derived from Devonian-Carboniferous sediments (mainly conglomerates in Beresford Stn). Associated soils are hard gravelly to stony. Not a Wetland. (BVG1M: 13c). |

| Protected areas | Kroombit Tops NP, Narrien Range NP, Nairana NP, Rundle Range NP, Goodedulla NP, Cania Gorge NP, Shoalwater Bay CP, Rundle Range RR, Bouldercombe Gorge RR, Broad Sound Islands NP, Blackwood NP, Gurgeena CP, Bania NP, Mount Etna Caves NP, Bouldercombe Gorge |
| Special values | 11.11.15: Potential habitat for NCA listed species: Capparis humistrata, Corymbia clandestina, Corymbia xanthope, Cycas megacarpa, Cycas ophiolitica. |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 6-15 years (shorter intervals north of bioregion: 5 - 10 years). INTERVAL_MIN: 6. INTERVAL_MAX: 15. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. All shrubby areas will carry fire after a good season. ISSUES: Management of this fire tolerant vegetation type should be based on maintaining vegetation composition, structural diversity, animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of habitat and mitigate against wildfires. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.11.15: This regional ecosystem has been subject to periodic canopy dieback due to drought in parts of central Queensland (Fensham and Holman, 1999). |
