Implementation: Effectiveness of sentinel (expatriate) concept is reported directly to MPI (Science & Risk – Plants & Pathways and Biosecurity Intelligence Team) and International Plant Sentinel Network (Botanic Gardens Conservation International). Generic learning is shared with other sentinel projects (i.e. B17.4, B19.4). Specific information on biosecurity risk organisms is provided to relevant parties (i.e. forage pests with Dairy NZ, Beef&Lamb) and to project B19.5.
