Fire management guidelines | SEASON: Spring (after rainfall). INTENSITY: Low. INTERVAL: 7-20 years. INTERVAL_MIN: 7. INTERVAL_MAX: 20. STRATEGY: Burn after recent rainfall when soil moisture is high. ISSUES: Restricted to Redbank Plains, Ipswich. Intact plant communities are probably extinct. Spring burns have an associated risk due to changing weather conditions post-burn. |
