| Special values | 7.12.34: Potential habitat for NCA listed species: Acacia longipedunculata, Calochlaena villosa, Croton densivestitus, Grevillea glossadenia, Homoranthus porteri, Coleus amoenus, Solanum angustum, Zieria obovata. |
| Fire management guidelines | SEASON: Cool, dry season (April-Sep). INTENSITY: Low to moderate. INTERVAL: 2-5 years. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Mosaic burn < 30%. Begin burning early in the fire season, with progressive patch fires burnt through the year. Stop burning when the network of fires and other breaks is sufficient to impede fire spread later in the year. Storm-burning may be used to add further diversity to the fire mosaic. ISSUES: An occasional moderate severity fire may be used to manage overabundant recruitment of trees. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. |
| Comments | 7.12.34: Distinguished from 7.12.24 by a tendency to occur in drier, more western zones and by the common presence of ironbarks or Corymbia citriodora, whereas 7.12.24 occurs in wetter areas and has either pure stands of E. portuensis or a co-dominance of C. intermedia. Distinguished from 7.12.30 by the dominance of E. portuensis. Threatened in some areas by timber harvesting operations that create disturbance and facilitate weed invasion. Widespread along the western edge of the bioregion, particularly common in the Kirrama-Oak Hills area and in the vicinity of the Atherton Tablelands. |
