III Agrobiodiversity and its use in Naban River Watershed National Nature Reserve: implications for bio- cultural diversity conservation Acknowledgements This research was part of LILAC project “Living landscapes China” funded by German Federal Ministry of Education and Research (BMBF) (FN.: 0330797A). The project provided field work infrastructure and expenses and I would like to express my gratitude towards that. I’m indebted to the German Academic Exchange Service (DAAD) for giving me a scholarship to carry out my graduate studies in Germany. Many people helped me during this work, without their support this research could not have been completed. I’m highly indebted to my supervisor Prof. Dr. Joachim Sauerborn for his friendly support, useful suggestions and advices which have enabled me to complete this dissertation. I would especially like to thank Dr. Gerhard Langenberger for his assistance and advises during the whole period of work. Many thanks also go to Mr. Liu Feng from administration office of the Naban River Watershed National Nature Reserve for his administrative and scientific help. Special thanks also to Mrs. Inga Häuser from project secretary office and Mrs. Liu Xuan from project regional office in China for their administrative assistance. I’m also grateful to my local assistance Mrs. Cai Yun for her incredible help, to nature reserve rangers, traditional healers and villagers (too many to name) for their kind help, cooperation, sharing their knowledge with me and wonderful hospitality. Finally I would like to thank my family for their prayers and support, to my dear wife, Ensieh Hajazimi and to my committee members, Prof. Dr. Joachim Müller and Prof. Dr. Reinhard Böcker for their advice and support.
