Codes of the matrix of impacts for candidate priority pests assessed under EFSA-Q-2024-00340

This zip file provides you the codes used to calculate the matrix developed for the assessment of impact on ecosystem services by candidate priority pests, produced under the second mandate on Priority Pests, received by the European Food Safety Authority (EFSA) from the European Commission, DG SANTE in 2022 (EFSA-Q-2024-00340).

During that project, EFSA was requested to assess 46 candidate priority pests. Among these 46 pests, 25 were selected, based on the expected impact on plant traits that have direct connection with ecosystem traits, and therefore with the ecosystem services.

The scope of the matrix is to report the impact on the assessed ecosystem services for all the impacted ecosystem types in terms of reduction of ecosystem services flow to the European Union.

The applied methodology is described in the guidance document titled "EFSA methodology for assessing the impact of plant pests to ecosystem services" and published in the EFSA Journal with the doi https://doi.org/10.2903/sp.efsa.2025.EN-9607.

The matrices completed for these 25 pests are available at https://zenodo.org/records/15699745.
