Management Notes (for the Swan NRM Region)
Kate Brown and Karen Bettink, Monday 18 July 2016

General Biology. Growth form. Tree. Reproduction. Seed, suckers. Dispersal. Birds, small mammals, water, garden refuse, soil movement, inappropriate plantings. Time to first flowering. 3 years. Toxicity. Unripe fruit can be fatal to horses, crushed ripe fruit causes respiratory difficulties in humans, contact with sap or resin can cause skin irritation. Vegetative regeneration strategy. Resprouts, produces root suckers. Seedbank persistence. Short, days - 1 year. Fire response. Established trees not killed by fire, rapidly recover from less severe burning or do not burn. Fire retards growth and/or kills smaller plants.

Notes. Forms dense thickets which shade out and smother native vegetation, can block access to creeks. Has been the target for biocontrol in the US. Allelopathic. Stems sprout prolifically after canopy damage. Physical damage to root system or canopy also increases root suckering.

Additional information. Origin. Tropical South America. History of use/introduction. Garden escape. Similar exotic species. Schinus molle var. areira.

Suggested method of management and control. Hand pull seedlings ensuring removal of all root material. Stem inject older plants using 50% glyphosate or basal bark with 250 ml Access® in 15 L of diesel to bottom 50 cm of trunk during summer. Avoid root disturbance until trees are confirmed dead. 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.
