Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Monday 26 August 2019

Alternative Names. Chinese sumac, paradise tree and copal-tree.

General Biology. Growth form. Tree. Reproduction. Seed, root suckers, stem layering. Dispersal. Wind, water, birds, machinery, soil movement, garden refuse. Time to first flowering. 2+ years. Toxicity. Bark, leaves and flowers are poisonous to humans and livestock. Also known to cause dermatitis in humans. Vegetative regeneration strategy. Resprouts, produces root suckers, stem layering. Woody structure. Ring porous. Fire response. Will resprout vigorously following fire.

Notes. Is an aggressive competitor due to its allelopathic properties, ability to tolerate a wide range of soils and the abundant suckers it produces from shallow roots. Will shade out smaller plants and create monospecific stands. Spreads rapidly via highly viable wind dispersed seed.

Additional information. Origin. China. History of use/introduction. Garden escape, widely planted as a street tree.

Suggested method of management and control. Apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (basal bark). For larger trees (greater than 30cm diameter) with thick bark stem inject 100% glyphosate. 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.
