| Short description | Acacia harpophylla open forest on sedimentary rocks |
| Structure code | Open Forest |
| Description | Acacia harpophylla open forest +/- Casuarina cristata and vine thicket species. Occurs on Cainozoic and Mesozoic sediments, especially fine-grained rocks. Not a Wetland. (BVG1M: 25a). |
| Supplementary description | Bean et al. (1998), H47 |
| Special values | 12.9-10.6: Potential habitat for NCA listed species: Callitris baileyi, Cupaniopsis tomentella. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately or light up remnant edges. Planned burns should be used to protect scrubs from fire incursion and to reduce fuel loads in order to prevent the spread of wildfire. Any planned fire lit near the edge of a remnant should be drawn away from remnant perimeter 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 in buffer areas 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 on margins as they can allow grasses such as buffel Cenchrus ciliaris and green panic Megathyrsus maximus to penetrate. |
| Comments | 12.9-10.6: Characteristic localities for the RE are the Lockyer Valley and west of Boonah. Extensively cleared for pasture and cropping. Only very small areas remain and these are subject to weed invasion, e.g. Asparagus Africans. |
