This guide provides easy-to-understand information on how good forest management practices and well implemented phytosanitary standards can minimise pest spread and facilitate safe trade. It explains how the International Standards for Phytosanitary Measures (ISPMs) and national plant protection organization (NPPO) regulations affect the import and export of forest commodities and how relevant ISPMs can be used to prevent pest introduction and spread. This publication will be of vital interest to people involved in nursery activities, planting, managing, harvesting, manufacturing, trading and transporting forest products. It will also benefit forest policy-makers, planners, managers and educators, particularly in developing countries.
