Network modelling of biosecurity risk associated with arable seed imports

Biosecurity outcome

  • Estimation of expected quarantine weed and contaminating seeds incursion rates.
  • Better understanding of high-risk nodes and pathways that may benefit from improved biosecurity measures.
  • Estimation of risk for different seed inspection thresholds, given the data.
  • Recommendations for data collection methods for better model parameterization and risk assessment. Depending on the data that is available.

Science outcome

  • Network modelling tools for seed traded
  • Risk determinations for crops and inspection levels
  • Capacity building in AgResearch/Lincoln

Key end users/stakeholders

Implementation:  New knowledge on biosecurity risk within seed pathways will be used by MPI (Science & Risk, Plants & Pathways standards).
