Introduction

The International Poplar Commission (IPC), founded in 1947, is a statutory body of the Food and Agriculture Organization of the United Nations (FAO). The functions of the IPC are to: (i) study the scientific, technical, social and economic aspects of poplar and willow cultivation; (ii) promote the exchange of ideas and material between research workers, producers and users; (iii) arrange joint research programs; (iv) stimulate the organization of congresses, meetings and study tours; (v) report and make recommendations to the Conference of FAO through the Director General of FAO; and (vi) make recommendations to National Poplar Commissions through the Director General of FAO and the Governments concerned. At present there are 37 member countries of the IPC, of which 14 are developing countries and five are countries with economies in transition.

IPC Sessions are held every four years. The previous meeting was in Budapest, Hungary in 1996. Five Working Parties as subsidiary bodies of the IPC reflect the main issues concerning the cultivation and utilization of the Salicaceae including (i) Poplar and Willow Genetics, Conservation and Improvement; (ii) Poplar and Willow Diseases; (iii) Poplar and Willow Insect and Animal Pests; (iv) Production Systems and Environmental Applications for Poplars and Willows; and (v) Logging and Utilization of Poplar and Willow Wood. There is also a Sub-committee on Poplar and Willow Nomenclature and Registration.

This report includes submitted abstracts to the meeting organizers including invited papers, oral presentations, and visual presentations (posters). They are listed here in alphabetical order by senior author's last name (from A to Z).
