Foothills and uplands on metamorphics, of the dry rainfall zone. Not a Wetland. (BVG1M: 9b). 7.11.21b: Grassland dominated by Themeda triandra (excluding Black Mountain examples). Foothills and uplands on metamorphics, of the dry rainfall zone. Not a Wetland. (BVG1M: 32b). |

| Fire management guidelines | SEASON: Cool, dry season (April-Sep). b: Early season burns (April-June). Later burns during storm season will reduce shrub invasion. INTENSITY: Low to moderate. b: Low, with occasional moderate. INTERVAL: 2-5 years. b: 2-3 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. b: Mosaic burn at a range of frequencies to create mosaic of post-fire responses. 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. b: Absence of fire can lead to a transition to shrubland. Moderate intensity fire will reduce this change and assist with weeds. |
| Comments | 7.11.21: Distinguished from 7.11.49 by its occurrence in drier, more north-western areas and by the common occurrence of species such as Erythrophleum chlorostachys, Melaleuca monantha, and Allocasuarina luehmannii. Texture contrast soils lower slopes. Poorly represented in protected tenures and threatened in some areas by timber harvesting. Western parts of ranges, north from about Gordonvale. The northern examples are generally in good condition, whist the southwest examples are suffering clearing and fragmentation. |
