Risk assessment frameworks for invasive species
One of the many functions of biosecurity staff in the OTs is that of carrying out risk assessments of new species, pathways and commodities. Staff do not have access to specialist risk assessment teams, and often lack both capacity and confidence to effectively assess risk. Under Darwin Plus project DPLUS074, CABI worked with St Helena and the Falklands to develop appropriate pest risk assessment templates and build capacity in their use. The OT Biosecurity Project built on this experience by rolling-out the resulting outputs to the Caribbean OTs through a training workshop held jointly with CABI in January 2020, together with follow-on help and advice in using the four risk assessment templates developed:
The report guidance document and templates for the Caribbean OTs can be found below. The PRA guidance document is complete and contains general guidelines, additional guidance notes for completing each template, pre-application and screening forms, and all four templates. The additional guidance notes, forms, and PRA templates are all available as separate files for ease of downloading and use. All documents are available in editable (Word document) format so that they can be completed, modified or adapted for use in other situations or Territories.
- PRA type 1: Planned introduction of plants, animal, commodities or other biological material
- PRA type 2: Planned introduction of a biological control agent
- PRA type 3: Risk of accidental introduction of an invasive alien species not specifically linked to the planned import of biological material
- PRA type 4: PRA for alien/invasive species already present in territory
