| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Low to moderate. INTERVAL: 7-25 years. INTERVAL_MIN: 7. INTERVAL_MAX: 25. STRATEGY: Aim for a burn mosaic of 40-60% over the burn area. A diversity of season and fire intensity is important, as well as spot ignition in cooler or moister periods to encourage mosaics. Late summer burns assist with maintaining control of fire intensity. ISSUES: Avoid repeated low intensity fires. Fires that are too frequent will eliminate obligate seeding species. Fire frequency and intensity should be such as to allow obligate seeders to reach maturity and produce viable seed. |
| Comments | 12.9-10.5a: Helidon hills region. 12.9-10.5b: Erected as the new RE 12.9-10.25 in August 2016. Tarong area. 12.9-10.5c: Erected as the new RE 12.9-10.26 in August 2016. Eucalyptus psammitica dominated areas mainly occur in Toohey Forest. 12.9-10.5d: Restricted to the far south of the Southeast Queensland bioregion. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
