Kazue Fujiwara is Professor Emerita of Yokohama National University and Research Professor in the Graduate School of Nanobioscience of Yokohama City University since 2010. She received her Doctor of Science from Tohoku University in 1972. Prof. Fujiwara is a vegetation scientist, adhering closely to classical standards and procedures but also able to apply vegetation science to field study and vegetation rehabilitation efforts in Asia, Europe, Africa and the USA. Her specialties are deciduous and evergreen broad-leaved forests, tropical and subtropical forests, the vegetation of mangroves, mires and coastlines in Asia through the world, as well as detailed vegetation monographs in Japan. In particular, she identifies relationship between potential natural vegetation and actual vegetation, and represents these on vegetation maps. She is also known for her interest in and extensive knowledge of the vegetation of the whole world, having studied vegetation in the field in about 60 countries or comparable regions, on all continents except Antarctica. She publishes specialized studies on Japan, mainland Asia, Southeast Asia, Kenya, eastern North America and Amazon forests often in comparison with other parts of the world. Prof. Fujiwara served as an INTECOL board member (2001-2008) and as a Vice-President of the International Association for Vegetation Science (2000-2007), remaining still in the Advisory Committee of the latter.
Franco Pedrotti is a botanist specialized in the study and cartography of vegetation, environmental cartography and ecological planning. He has also worked in conservation of nature and its resources on the technical and scientific level, as well as in its promotion. He served as President of the Italian Botanical Society from 1982 to 1990, and as President of the Association Internationale Francophone de Phytosociologie from 1982 to 2002, and was awarded honorary degrees in Biology from the "Babes-Bolyai" University of Cluj-Napoca and the "A.I. Cuza" University of Iasi (Romania), in Ecology and Biogeography from the University of Palermo (Italy) and in Gearchitecture from University of Brest (France). He taught Botany, Geobotanical Cartography and Conservation of Nature and its Resources at the Universities of Padova, Milan, Catania, Ferrara and Camerino; currently he is Professor Emeritus at the University of Camerino. He published several textbooks for university students of Biology and Natural Sciences on conservation of flora, vegetation, the environment and protected areas.
