Seeds dispersed by explosive dehiscence and contaminated soil on animals. Human-mediated dispersal through dumping of garden waste and contamination of machinery and vehicles.

Forms dense thickets, outcompeting native vegetation and altering species composition. Facilitates invasive animals and weeds. Nitrogen fixer. Reduces pasture grazing capacity and impedes stock movement. Poisonous to stock. Reduces plantation productivity.

Site Management

Minimise creating soil disturbance where seeds can germinate and re-establish. Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
