Short description | Semi-evergreen vine thicket and microphyll vine forest on Cainozoic igneous rocks |
Structure code | Closed Forest |
Description | Semi-evergreen vine thicket and microphyll/notophyll rainforest. In drier or rockier habitats, Casuarina cristata or Acacia harpophylla may dominate the tree layer. A dense shrub layer of Acalypha eremorum, Diospyros humilis and Planchonella cotinifolia is always present. In a few localities, emergent Eucalyptus orgadophila or Corymbia erythrophloia may persist after invasion by "vine-thicket" species. Occurs on gently undulating plains, rises and low hills on Cainozoic igneous rocks. Not a Wetland. (BVG1M: 7a). |

Special values | 11.8.13: 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 | 11.8.13: May invade areas of adjacent woodlands, such as RE 11.8.5. |
