| Special values | 12.3.13: Potential habitat for NCA listed species: Acacia attenuata, Acacia baueri subsp. baueri, Allocasuarina emuina, Blandfordia grandiflora, Boronia keysii, Boronia rivularis, Eucalyptus conglomerata. |
| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Moderate (to high; due to the inherent characteristics of highly flammable vegetation). INTERVAL: 8-20 years. INTERVAL_MIN: 8. INTERVAL_MAX: 20. STRATEGY: Aim for a burn mosaic of 40-80%. Ensure planned burn conditions are conducive to maintaining integrity of the landscape (i.e., use good soil moisture, recent rainfall and standing water on the ground). ISSUES: Intervals at the upper end (12-20 years) of the recommended regime may be desirable to counteract detrimental impacts of a high intensity fire over 100% of landscape. This 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. |
| Comments | 12.3.13: Generally a palustrine wetland although in cane growing areas near Bundaberg some have been converted to lacustrine water bodies associated with the construction of bunding and levees. |
