Dispersal

Seeds dispersed by birds, water, soil movement and possibly possums.

Impact on environment

Forms dense stands and is assumed to exclude native plants and prevent seedling recruitment.

Control

Site Management

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.

Recommended approaches

Physical control

Method: Dig out.

Plant parts requiring disposal: Seeds.
