Beech International Research Group

Within the framework of the international activities of Forest Research Division, a department called the Beech Research, co-operates with the International Forest Research Organization (IUFRO). The goal of this group is to support forest scientists and those who interested in researching in the field of ecology, forestry, genetics and forest management in Beech (Fagus) forests, which is mainly realized through international meetings and conferences.

The group hopes to create frequent opportunities for researchers and managers to meet and exchange scientific and practical knowledge that have been accumulated separately in Europe, Asia and North America. We also hope that our cooperation will serve as inspiration for students to identify interesting topics to study and interesting advisers to contact in many countries. Scientific meetings including field excursions will take place in various parts of the Fagus range.
