HB: Prevention of New Biosecurity Risks

Focus on new incursions and those that provide a ‘stitch in time’ outcome, with significant financial returns.


Delayed action on new biosecurity risks often results in a no-win situation, with ongoing financial loss / burden and environmental impacts. Good communication and partnerships with others will support better biosecurity outcomes.

Examples of Local Action

  • Conduct ongoing R&D to identify the best control measures (biological control, etc) of the main weeds (currently Siam weed, African Tulip trees, Navua Sedge, Gamba Grass) and use this information to conduct on ground weed management.
  • Continue with current biosecurity programs and review regularly to ensure value for money and outcomes achieved.
  • Implement a coordinated control program on Gamba Grass to prevent its spread to the lower Herbert catchment eg. use adaptive fire regimes to control infestations in the upper catchment, conduct education and awareness raising in the lower Herbert, coordinate stakeholder planning now to prepare and respond to the threat of Gamba Grass.
