| Special values | 7.12.24: Potential habitat for NCA listed species: Arytera dictyoneura, Corymbia leptoloma, Marsdenia rara, Coleus gratus. |
| Fire management guidelines | SEASON: Cool, dry season (June-Sep). c: 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: Ignition is most likely during hot, dry season (Oct - Jan). These fires are typically high intensity fires that can be difficult to control. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. c: 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 | 7.12.24: Extensively cleared near Cardwell for *Pinus caribaea plantations. Distinguished from 7.12.34 by a tendency to occur in wetter zones and by the either pure stands or co-dominance with C. intermedia, whereas 7.12.34 tends to occur in drier, more western areas, and often has ironbarks or Corymbia citriodora as a component. South western examples may be subject to timber harvesting operations that create disturbance and facilitate weed invasion. Mainly central and southern parts of the bioregion, predominantly on the eastern fall of the main ranges. |
