Special values 12.12.9: Habitat for threatened plant species including Cassinia collina and near threatened species including Acacia pubicosta and Comesperma breviflorum. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus).
Fire management guidelines SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. 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: The fire regime should maintain a mosaic of grassy and shrubby understoreys. May be difficult to burn due to sparsity of grasses.
Comments 12.12.9: Frequent fire can favour fire-tolerant species at the expense of fire-sensitive species.
