| Special values | 12.8.23: Potential habitat for NCA listed species: Cupaniopsis tomentella. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Planned burns should be used to protect scrubs at their margins from fire incursion and to reduce fuel loads in order to prevent the spread of wildfire. Burn less than 10% in any year. Small and spaced spot fires lit on the edge of remnants should be used to draw fire away from the perimeter of remnants using prevailing wind conditions. ISSUES: This vegetation primarily requires protection from fire, however carefully managed low intensity fires will be useful in buffering remnants from surrounding vegetation and reducing fuel loads, leading to overall protection of the RE from wildfire. Moderate fires may assist in the regeneration of hard-seeded species and occasional high intensity fires may enhance acacia regeneration. Frequent fires may eliminate acacia, casuarina and other obligate seeding species. Remnants can be degraded by wildfire and planned burns if implemented inappropriately. |
| Comments | 12.8.23: Melaleuca bracteata conspicuous along associated watercourses. Cleared for pasture and cropping. |
