The Guide interprets the standards relevant to international forestry pest risks into the language and framework of forest health, outlining how generic principles, such as pest risk analysis and surveillance, can be applied by forest health agencies and forest managers at all levels. It focuses on the practical application of the standards in the forest sector. The guide was produced by an international core group of scientists, phytosanitary authorities, forest experts and industry representatives and reviewed by more than 100 specialists from 46 countries.
