Short description Eucalyptus melanophloia woodland on igneous rocks
Structure code Woodland
Description Eucalyptus melanophloia and Corymbia erythrophloia +/- E. populnea grassy woodland. Eucalyptus moluccana sometimes present on colluvial lower slopes. Occurs on undulating rises and low hills formed from Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 17b).

Vegetation communities in this regional ecosystem include:
11.12.2a: Eucalyptus melanophloia and/or E. orgadophila +/- Corymbia erythrophloia woodland. Occurs on undulating plains. Not a Wetland. (BVG1M: 11a).
11.12.2b: Eucalyptus moluccana woodland. Generally occurs on colluvial slopes on undulating granite country. Not a Wetland. (BVG1M: 13d).
11.12.2c: Dichanthium spp. grassland +/- scattered Eucalyptus melanophloia, E. orgadophila or Corymbia erythrophloia. Occurs on mid to lower slopes on granodiorites and felsic granities producing heavy clays soils. Not a Wetland. (BVG1M: 30b).

Protected areas Goodedulla NP, Kroombit Tops NP, Mazeppa NP, Mount Leura CP, Cania Gorge NP
Special values 11.12.2: Potential habitat for NCA listed species: Cycas ophiolitica, Sannantha brachypoda.
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: 3 - 7 years). 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. 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.
