The Forest Research Institute (FRI) was established in 1961 by the Ministry of Agriculture as Forest Research Station of Macedonia and Thrace. In the course of time it has developed into the present Forest Research Institute.
In 1989 the Institute was integrated into National Agricultural Research Foundation (NAGREF) under the same official title. FRI brings together many disciplines to develop a better understanding of forests, rangelands and environment and society's interactions and impacts on it.
FRI has a strong emphasis on bringing scientists from different disciplines together to carry out interdisciplinary and multidisciplinary research. This research ranges from fundamental understanding of the forests and rangeland ecosystems, their systems and processes, through to integration of applied research to address specific issues and conflicts.
