| Short description | Eucalyptus crebra woodland on igneous rocks |
| Structure code | Woodland |
| Description | Eucalyptus crebra +/- Corymbia erythrophloia woodland to open woodland. E. melanophloia is rarely present and may be locally dominant. Also includes localised areas may be dominated by E. persistens. Occurs on ranges on igneous rocks. Not a Wetland. (BVG1M: 13c). Vegetation communities in this regional ecosystem include: 11.12.1a: Eucalyptus crebra +/- E. exserta woodland. Occurs on undulating rises. Not a Wetland. (BVG1M: 13c). 11.12.1b: Eucalyptus persistens low woodland. Occurs on acid-volcanic rocks. Not a Wetland. (BVG1M: 19d). 11.12.1c: Dichanthium spp. grassland +/- scattered Eucalyptus crebra, Corymbia erythrophloia. Occurs on mid to lower slopes on granodiorites and felsic granities producing heavy clays soils. Not a Wetland. (BVG1M: 30b). |

| Special values | 11.12.1: Potential habitat for NCA listed species: Acacia islana, Capparis humistrata, Corymbia petalophylla, Cycas megacarpa, Cycas ophiolitica, Macrozamia crassifolia, Sannantha brachypoda, Solanum graniticum. |
| 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. b, c: Various. Mainly low, but also moderate. INTERVAL: 6-15 years (shorter intervals north of bioregion 5 - 10 years). b, c: >3years. INTERVAL_MIN: 3. 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. b, c: Low to moderate burns can help limit the spread of fires. Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. 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. b, c: Fire can be used to control weed invasions, although there are also risks of promoting weeds. |
| Comments | 11.12.1: Areas of this regional ecosystem within the Bowen district may have a ground stratum of Bothriochloa pertusa (Indian cooch). |
