| Special values | 7.11.26: Potential habitat for NCA listed species: Xanthostemon verticillatus. |
| Fire management guidelines | SEASON: Avoid dry conditions or fires will spread too much. April to July or as early as March, conditions permitting. INTENSITY: Moisture and topography affect severity. Low to high. INTERVAL: 6-10 years with some areas burnt at longer intervals. Fire intervals less than 6 years are too short to allow replenishment of obligate seeders. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Mosaic burns will be achieved through use of natural features such as topography and creek-lines. Burn in association with surrounding vegetation. Protection relies on the broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Fire exclusion and buffering from fire are not necessary. ISSUES: Any planned burning should be conducted in association with plans for surrounding vegetation. Often contains obligate seed regenerating species and as such, the application of frequent fire may reduce species richness if the intervals between fire are not sufficient for plants to produce seed (e.g., loss of Banksia plagiocarpa). Too frequent a fire frequency may result in a net loss of nutrients over time from an already nutrient poor system. Burn when water and moisture are present on the ground. |
| Comments | 7.11.26: Widespread across the bioregion north from about Tully. Molasses grass is a common weed of this ecosystem and is a major threat. 7.11.26c: Minor components: 13f and 16f. (Webb and Tracey). 7.11.26f: Patches of bare rock < 0.2 ha are defined as more open areas of the surrounding ecosystems. |
