This paper summarizes the approach of a recent EPPO study and some of its key outputs. The study was commissioned to aid pest risk analysis and the development of risk management measures for movements of woodchips and other similar commodities. Thesewood commodities represent a significant pathway for the introduction of pests of trees into new areas, and the pathway is becoming more important as trade in such commodities increases. An indication of the relative risk of different commodities for different types of pest was proposed as a conclusion of the study. More information is now needed on the quantities and nature of the material being moved into and within the EPPO region, and the treatments to which it has been subjected. This may not be clear from commercial documentation and trade data so national plant protection organizations (NPPOs) are encouraged to gather and share such information from inspections of consignments.
