| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Plan for low to moderate. Unplanned occasional high intensity wildfire will occur. b: Low to moderate. INTERVAL: 4-8 years maintains a healthy grassy system. 8-20 years for shrubby elements of understorey. b: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Needs disturbance to maintain RE structure (eucalypt overstorey with open understorey of predominantly non-rainforest species). Any moist sclerophyll that is relatively open with a mixture of grasses and shrubs should be a priority for fire management to retain RE structure. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: Frequent fire is needed to maintain understorey integrity, keeping more mesic species low in the profile of the understorey so that other species can compete. The Bauple longterm fire study site has shown this RE resilient to frequent burning with a mix of intervals, including annual and infrequent burns. It is essential that wildfires are not the sole source of fire in this ecosystem. A follow-up burn soon after a high intensity wildfire can be considered to reduce germinating/resprouting mesic species. The RE occurs on shallow rocky soils, so there tends to be no moisture holding capacity. Control of weeds (e.g., Lantana camara, Ochna serrulata, Praxelis clematidea) might be required. |
| Comments | 12.9-10.17: This RE is being remapped to the community level. 12.9-10.17b: Typically occurs in moister coastal environments and is more species rich than 12.9-10.2. 12.9-10.17e: Mostly found in south-western parts of the bioregion including Carneys Creek and sandstone hills flanking volcanic plugs south of Maroon Dam. |
