This paper is one of a series of FAO documents on forest-related health and biosecurity issues. The purpose of these papers is to provide early information on on-going activities and programmes, and to stimulate discussion.

The study was carried out in March 2003, and was financially supported by the FAO-Netherlands Partnership Programme on Agro-Biodiversity.

The author would like to thank the following persons for helping to prepare some of the case studies (taken from the Global Invasive Species Programme Toolkit) presented in this paper. Case Study 4 was prepared by S. Soetikno, CAB International South-East Asia Regional Centre, Malaysia Agricultural Research & Development Institute; Case Study 11 was prepared by Ross Morgan, National Manager, Forest Health Forest Health Advisory Services, New Zealand.
