Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Thursday 21 December 2017

General Biology. Growth form. Vine. Life form. perennial. Reproduction. Resprouter, Seed,. Dispersal. Wind, water, garden waste. Time to first flowering. 1 year. Vegetative regeneration strategy. Resprouts. Seedbank persistence. No dormancy. Fire response. Adults reprout after fire, flowering and setting fruit within 1 year.

Notes. In recent years Wonga vine has become established in Marri/Jarrah woodlands on the Darling Plateau where it is a particularly serious weed. A long lived perennial woody climber it forms dense layers in low canopy and prevents the establishment of native plant seedlings. It reaches into the canopy of taller trees and appears to reduce growth and recruitment. Tolerates hot to cool temperatures and high to moderately low rainfall. Wonga Vine has distinct juvenile and adult leaves. The juvenile leaves have 8-17 small leaflets. The adult leaves have 3-9 linear to narrowly ovate leaflets. Seed pods are a dark brown oblong-ellipsoid capsule with thick woody valves. Seeds are orange, semi-flat ovoid to 10 mm long and 7 mm wide, with papery wings.

Additional information. Origin. Kimberley, central and eastern Australia, New Guinea, Indonesia and New Caledonia.. History of use/introduction. Introduced into southwest WA as a garden plant.

Suggested method of management and control. Spray 1% glyphosate or metsulfuron-methyl 600g/kg (5g/10L) or triclopyr 600 EC (30ml/10L) or triclopyr 120g/L (15ml/L). Cut and paint stump: 2% glyphosate. Try basal bark application 250ml Access® in 15L of diesel to bottom 50cm of main stem. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
