| Fire management guidelines | SEASON: Avoid dry conditions or fires will spread too much. April to July or as early as March, conditions permitting. c: April-May or in some years through until Sep. d: Cool, dry season (April-Sep). INTENSITY: Moisture and topography affect severity. Low to high. c: Low to occasional moderate. d: Low to moderate. 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. c: 6-10 years. d: 2-5 years. INTERVAL_MIN: 2. 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. c: Mosaic burn 25-70% of the target area. Across the landscape burn different areas at different intervals to add diversity. d: 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. i,j: Maintain appropriate mosaic burning in surrounding country. Do not protect from fire but do not burn deliberately. 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. c: Occasional moderate fire can assist management of overabundant tree recruitment. Too frequent fire can eliminate shrubs which require several years before they set seed. d: 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. i,j: This is mainly a self protecting community. |
| Comments | 7.12.65: Distinguished from other Allocasuarina dominated rock-pavement regional ecosystems by its occurrence in dry western areas. Scattered across the entire length of the bioregion, mainly in western areas and more common in the south. 7.12.65e: Minor components: 13f and 16f. (Webb and Tracey). 7.12.65k: Patches of bare rock < 0.2 ha are defined as more open areas of the surrounding ecosystems. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
