| Protected areas | Snake Range NP |
| Special values | 11.11.18: Potential habitat for NCA listed species: Atalaya collina, Brachychiton guymeri, Dansiea elliptica, Graptophyllum excelsum, Hernandia bivalvis, Macropteranthes leiocaulis. |
| 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 in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Grazing may be useful in managing fuel loads created by introduced grasses such as buffel. |
| Comments | 11.11.18: This regional ecosystem occurs on more gently slopes that 11.11.5. Extensively cleared for cropping and pasture and subject to fragmentation and associated degradation due to fire and weed invasion. |
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.
