Book (stand-alone)Proceedings of the regional seminar-workshop on harmonizing methods in risk assessment and management of forest invasive alien plant species in Southeast Asia 2015
Also available in:
No results found.Rapidly accelerating trade and travel have allowed both intentional and unintentional movements of plant and animal species between different parts of the globe. The consequences are often unexpected and disastrous. Invasive alien species are regarded as one of the leading threats to natural ecosystems and biodiversity given that the effects are usually irreversible. These proceedings report on the outcome of a meeting held in Bogor, Indonesia from 2 to 5 December 2014 on harmonizing risk assess ment and management of forest invasive alien plant species in Southeast Asia. The report identifies gaps in regional capacities and identifies solutions and good practices aligned with international standards. Conclusions and recommendations as well as country reports and resource papers are included in the report. -
Book (series)Guide to the classical biological control of insect pests in planted and natural forests 2019
Also available in:
No results found.Insect pests damage millions of hectares of forest worldwide each year. Moreover, the extent of such damage is increasing as international trade grows, facilitating the spread of insect pests, and as the impacts of climate change become more evident. Classical biological control is a well-tried, cost-effective approach to the management of invasive forest pests. It involves the importing of “natural enemies” of non-native pests from their countries of origin with the aim of establishing permanent, self-sustaining populations capable of sustainably reducing pest populations below damaging levels. A great deal of knowledge on classical biological control has been accumulated worldwide in the last few decades. This publication, which was written by a team of experts, distils that information in a clear, concise guide aimed at helping forest-health practitioners and forest managers – especially in developing countries – to implement successful classical biological control programmes. It provides general theory and practical guidelines, explains the “why” and “how” of classical biological control in forestry, and addresses the potential risks associated with such programmes. It features 11 case studies of successful efforts worldwide to implement classical biological control. -
Brochure, flyer, fact-sheetInvasive beetle threatens forest and fruit trees 2019
Also available in:
No results found.The polyphagous shot hole borer (PSHB) is an ambrosia beetle (Coleoptera: Curculeonidae: Scolytinae) native to Asia, together with its fungal symbiont Fusarium euwallaceae. PHSB attacks agricultural and forestry crops, street and garden trees, as well as several native tree species. It has emerged as an important invasive pest killing avocado and other trees in Israel, California and the United States. The PSHB is one of three species in the Euwallacea fornicatus species complex, the taxonomy of which remains to be resolved. The PSHB and its fungus were discovered in South Africa in 2017. The beetle has since then spread to a number of provinces in the country where it has infested and killed large numbers of trees. This small ambrosia beetle has an extraordinary wide host range. It has already been reported on many popular tree species grown in urban areas of South Africa, and is also a pest of pecan nut trees, avocado and other fruit trees. To help member countries address and manage the increased threats to forest health from invasive species such as PSHB, FAO facilitates the Forest Invasive Species Networks for Africa, Asia-Pacific, Europe and Central Asia and the Near East. These networks improves the exchange of information, knowledge and expertise on invasive species issues and enhance collaboration in the regions.
