Fire management guidelines INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction burning in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Exotic grasses, such as Guinea grass and Buffel grass, can fuel fires that carry into and damage vine thickets. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Herbicide control of exotic grasses, or short term grazing, on the edge of vine thickets will reduce the risk of wildfires damaging vine thickets.
Comments 11.12.12: This regional ecosystem occurs on rocky headlands and has a sparse understorey compared to other Araucarian dominated ecosystems.

1 Estimated extent is from version 13.1 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.
