PREFACE ABOUT TROPENBOS The Tropenbos Foundation was established in 1988 by the Government of The Netherlands with the objectives to contribute to the conservation and wise use of tropical rain forest by generating knowledge and developing methodologies, and to involve and strengthen local research institutions and capacity in relation to tropical rain forests. The Tropenbos Programme carries out research on moist tropical forest land at various locations around the world. At present (semi-) permanent research sites are located in Colombia, Guyana, Indonesia, Cote d'Ivoire and Cameroon. At the different locations, research programmes follow an interdisciplinary and common overall approach, with the aim to exchange data and make results mutually comparable. ABOUT THE TROPENBOS-CAMEROON PROGRAMME AND ITTO PROJECT PD 26/92 The present publication has been produced in the framework of ITTO Project PD 26/92, which is an integral part of the Tropenbos-Cameroon Programme (TCP). The research on which this publication is based, was financed by the International Tropical Timber Organization (ITTO), the Common Fund for Commodities (CFC), the Directorate General for International Cooperation of The Netherlands' Ministry of Foreign Affairs (DGIS), the Tropenbos Foundation and the implementing agencies mentioned below. The Tropenbos-Cameroon 'Programme was established in 1992 by the Cameroonian Ministry of Environment and Forests (MINEF) and the Tropenbos Foundation. The general objective of TCP is to develop methods and strategies for natural forest management directed at sustainable production of timber and other forest products and services. These methods have to be ecologically sound, socially acceptable and economically viable (Foahom and Jonkers, 1992). TCP consists of fourteen interrelated projects in the fields of ecology, forestry, economy, social sciences, agronomy and soil science. In 1994, ITTO and CFC decided to co-finance six of these projects, which together form ITTO project PD 26/92. The 'Office National de Developpement des Forets' (ONADEF) is the agency responsible towards ITTO and CFC for the implementation of the Project PD 26/92. The implementing agencies involved in the present study are the Winand Staring Centre for Integrated land, Soil and Water Research (SC-DLO), the 'Institut de la Recherche Agricole pour le Developpement' (lRAD) and Wageningen Agricultural University (WAU). ACKNOWLEDGEMENTS The authors wish to thank those who have contributed to the overall land inventory of the TCP research area. We gratefully acknowledge the assistance of the Cameroonian Ministry of Environment and Forests, the Tropenbos Foundation, the 'Office National de Developpement des Forets', the 'Institut de la Recherche Agricole pour le Developpement', the International Tropical Timber Organization, the Common Fund for Commodities, the Winand Staring Centre for 9
