| Description | Semi-evergreen vine thicket +/- Casuarina cristata. May commonly include Planchonella cotinifolia, Lysiphyllum hookeri, Capparis spp. and Terminalia oblongata, with lower stratum of Elaeodendron australe, Denhamia oleaster and Pittosporum spinescens. A ground layer of Ancistrachne uncinulata, Cheilanthes spp., and Solanum ellipticum may be present. Occurs on Cainozoic clay plains including extensively weathered Tertiary basalt. Not a Wetland.

| Protected areas | Dipperu NP (S) |
| Special values | 11.4.1: Habitat for the near threatened plant species 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 | 11.4.1: Extensively cleared for pasture. |
