| Fire management guidelines | SEASON: Early to mid-dry season. INTENSITY: Low to moderate. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Restrict extent and intensity of fires. High intensity and extensive fires will degrade vegetation structure and destroy animal habitats. Burn only under mild conditions. |

1 Estimated extent is from version 13 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
