In the project, Swedish risk ranking of plant pests, regulated plant pests relevant to Sweden will be assessed and ranked to provide scientific-based information on the risk that these pests may constitute for plant health in Sweden. In addition, non-regulated pests may also be included to evaluate the risk they constitute for Sweden. This report describes the methodology used and presents the results of the pests ranked to date (Section 3 and Appendix 3).

The FinnPRIO model, used in this project, enables rapid assessments and ranking of plant pests based on different components included in Pest Risk Analyses (PRAs), i.e. the likelihoods of entry, establishment & spread, magnitude of impact and feasibility of management. The model was developed for Finland and could be used for Sweden with minor amendments to the instructions. The instructions guide the selection of suitable answer options to the questions on which the model is based. All amendments done are shown in Appendix 1. Assessments were conducted for 108 plant pests and scores for each component and risk (Entry × Establishment & Spread × Impact) are presented. Different aspects of the model and the interpretation of the results that are important to take into consideration when using the information are outlined. New pests will be assessed and ranked on an ongoing basis.

Risk ranking of plant pests at national level, such as the risk score described in this report, provides valuable information to support plant health risk management decisions and resource allocation. Since risk ranking is based on quick risk assessments, additional in-depth analysis may be required in certain cases to provide further justifications prior to decision-making on plant health risk management level.
