| Short description | Deciduous vine thicket on karst outcrops |
| Structure code | Closed Forest |
| Description | Deciduous vine thicket dominated by Croton arnhemicus (hard cascarilla), Diospyros geminata (scaly ebony), Dendrolobium arbuscula (chillagoe pea) and Elaeodendron melanocarpum (black olive plum) with Terminalia subacroptera, Mimusops elengi and Dinosperma erythrococcum common. There are scattered or clumped emergents of Ficus virens var. virens (white fig), Ficus obliqua (small-leaved fig), Ficus rubiginosa forma glabrescens (rusty fig), Gyrocarpus americanus subsp. sphenopterus (helicopter tree), Bombax ceiba (silk cotton tree), Garuga floribunda var. floribunda, Mimusops elengi (red coondoo) and Ficus drupacea (hairy fig). Dendrobium bigibbum (Cooktown orchid) is a common epiphyte throughout with the vines Cayratia cardiophylla, Cissus adnata and Cissus reniformis being common. The very sparse to mid-dense shrublayer is dominated by Eugenia reinwardtiana (beach cherry) with Denhamia fasciculiflora, Graptophyllum excelsum (scarlet Fuchsia), Gossia sankowskyorum (lignum), Phyllanthus novae-hollandiae, Tabernaemontana orientalis (iodine bush), Turraea pubescens (native witch-hazel) Drynaria spp. and Ziziphus oenopolia (wine jujube). The ground layer is mostly bare ground and litter with Proiphys amboinensis (Cardwell lily), Plumbago zeylanica (wild Plumbago), Commelina ensifolia (wandering Jew), Scleromitrion polycladum and occasionally Dendrocnide moroides (Gympi Gympi) common. Occurs on karst outcrops. Not a Wetland. (BVG1M: 7b). |

| Special values | 3.11.20: Potential habitat for NCA listed species: Dendrobium bigibbum, Hardenbergia sp. (Mt Mulligan J.R.Clarkson 5775). |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No deliberate fire management required within this unit. Undertake fuel reduction burns in surrounding vegetation utilising multiple small fires throughout the appropriate season to manage biodiversity values and to limit the extent and reduce risks of wildfire. ISSUES: Fire sensitive vegetation type. |
| Comments | 3.11.20: Occurs on limestone karst, with plants growing between or around exposed limestone with limited soil in between. Includes areas where bare rock is dominant with scattered trees. Areas on metamorphic hills and slopes may have a different suite of species. Limited extent predominantly on and adjacent to Kings Plain station in the south of the bioregion. |
