With increasing global trade, new threats to forest health emerge due to the increased risk and frequency of trade-driven international pest movement. In the last decade several pests have been introduced into other countries and continents through international trade, and these have contributed to the international recognition of the importance of phytosanitary measures. How much do you know about the health of forests? FAO, using an integrated approach to deal with forest health problems, has produced the Guide to implementation of phytosanitary standards in forestry that provides easy to understand information about everything you should know to help protect the forests from pests. The page also links to an interactive training course developed by FAO and IPPC for anyone wishing to learn more about the importance and relevance of phytosanitary measures in the international trade in forest commodities.
