Short description Semi-evergreen vine thicket on alluvial plains
Structure category Dense
Description Semi-evergreen vine thicket or semi-deciduous notophyll vine forest, frequently with emergent Eucalyptus tereticornis or E. raveretiana. Common species include Diospyros humilis, D. geminata, Brachychiton australis, B. rupestris, Geijera salicifolia, Lysiphyllum spp., Mallotus philippensis and Streblus brunonianus. Occasional shrubs such as Carissa ovata may occur. Forbs such as Nyssanthes spp. may also be present. Occurs on Cainozoic alluvial plains. (BVG1M: 7a)

Vegetation communities in this regional ecosystem include:
11.3.11x1: Semi-evergreen vine thicket. Common tree species include Canarium australianum, Falcataria toona, Pleiogynium timorense, Cochlospermum gillivraei, Terminalia porphyrocarpa, and Chionanthus ramiflorus. Araucaria cunninghamii is absent. The understorey / shrub layer is dense with species such as Memecylon pauciflorum, Murraya ovatifoliolata, Aidia racemosa, Turraea pubescens, Mallotus philippensis, Ixora timorensis, Strychnos psilosperma, Pittosporum spinescens and Gossia bidwillii. The ground layer is sparse, and includes Ancistrachne uncinulata, Drynaria sparsisora, Adiantum aethiopicum, Coleus graveolens and Scleria sphacelata. Vine and epiphytes are common, including Pachygone ovata, Cissus oblonga, Bonamia dietrichiana, Stephania japonica, Jasminum didymum subsp. Racemosum, Abrus precatorius, Pisonia aculeata and Secamone elliptica. Occurs on coastal alluvial plains. (BVG1M: 7a)

Fire management guidelines 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 11.3.11: Extensively cleared for cropping and grazing. Remnants subject to invasion by weeds such as Guinea grass (*Megathyrsus maximus var. maximum) and trampling by livestock.
