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.
