The Department of Agriculture, Forestry and Fisheries conducts pre-border weed risk assessments as part of its international obligations to prevent the introduction (mainly through trade) of species that are likely to establish, spread and become invasive pests of plants and plant products. This is the first step in a series of a complex scientific process called Pest Risk Assessment in the division Pest Risk Analysis within the Directorate Plant Health. Weed risk assessment is conducted on either a genus or a species level looking at various regulations as well as characteristics of the plants. At the end of the assessment, a decision to issue an import permit or not is informed by the findings on those aspects. In the year 2013, a total of 23 assessments were conducted with about 50 still to be processed.
