| Structure code | Closed Forest |
| Description | Semi-evergreen vine thicket which may have emergent Acacia harpophylla, Casuarina cristata and Eucalyptus spp. Occurs on Cainozoic igneous rocks. Generally restricted to steeper, rocky hillsides. Not a Wetland. (BVG1M: 7a). |

| Special values | 11.8.3: Habitat for threatened plant species Croton magneticus. |
| 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 | 11.8.3: Areas in subregion 31 are contiguous with similar vegetation in the South East Queensland bioregion. Areas across the bioregion. Many remaining areas in coastal parts of the region have been invaded by the exotic Lantana camara and pasture grasses. These exotic weed species provide increased fuel loads which leads to increased wildfire and associated damage to the tree layer. Semi-evergreen vine thicket may invade adjacent regional ecosystems, particularly brigalow-belah in the absence of fire. |
