As verified from the reports of the two previously held seminars in 2003 in Japan and 2004 in Taiwan ROC, the incidence of introduction of biological invasive alien species in the region has increased along with increases in global trade and human travel. Many plants(including weeds), animals(including insects), and microbes have invaded many countries. Theeconomic damage and ecological impacts caused by these invasive alien spicies have also been increasing. This important issue can only be resolved effectively by means of regional/international cooperation. Invasive alien organisms have become a vital concern, and the need to exchange research and monitoring information on this concern has become more important and urgent than ever. Toward this end, maintaining a database to facilitate international cooperation in resolving this major issue is of significant importance.
