Local uses of tree species and contribution of mixed tree gardens to livelihoods of Saleman village near the Manusela National Park, Seram Island, Maluku (Indonesia) Master’s thesis Ariane Cosiaux Master “Biodiversité Végétale Tropicale” 2012 Ariane Cosiaux 2012 Master’s internship from 7 March to 17 August 2012 at : Center for International Forestry Research (CIFOR) Jalan CIFOR, Situ Gede Bogor Barat 16115 Indonesia Supervisor : Yves Laumonier CIRAD scientist in the research unit « Tropical Forest Goods and Ecosystem Services » Aknowledgments I first want to thank Yves Laumonier for allowing me to do this internship, for his availability and advices. And I want to thank him for allowing me to discover the amazing Island of Seram. I would like to thank also Pak Purwanto from LIPI for his kindness and his invaluable advices for the ethnobotanical part of my study. I am grateful to him for his help to the realization of my questionnaire in bahasa Indonesia and his encouragements during the first two weeks of my field work. I am so grateful for the hospitality of the Saleman village. First I want to thank Nenek In and Hapipa for hosting me during my field work. Then I want to thank my field assistant Jul who help me and take care of me. A special thank goes to Bapak Hadir who taught me the name of plants in bahasa Saleman, for his kindness and availability. I also would like to thank Bapak Mustafa and Mama Ratna who also take care of me and help me for collecting voucher specimens. Finally, I like to thank Andre, Yaren and all the member of Nenek In family. At CIFOR, I want to thank the other member of the Colupsia project, Pak Wyono and Pak Danan for their help and thanks to Popi Astriani who took care of all the administrative documents. I am also grateful to Pak Yan for drying my voucher specimens and to Pak Ismael, Bogor Herbarium, for all species identification. A final thank to Edith, Anis, Caroline, Marine, Anne Sophie, Thibaut, Nicolas, Jeffrey, Suzanne (my friends in Bogor) and my family for their support.

General context 1) Deforestation and forest degradation in Indonesia Currently, there is little doubt that tropical ecosystems are exceptionally rich and contain much of the terrestrial biodiversity. However, the rapid and extensive forest degradation, involving modification of ecosystems and fragmentation of habitats lead to an alarming loss of biodiversity (Laurence 1999). Most of the 25 “biodiversity hotspots” defined by Myers et al. (2000) are located in the tropics and characterized by high level of endemism and habitats loss. Indonesia overlaps with two of these: the Sundaland (Western Indonesia) and the Wallacea (Eastern Indonesia). As part of the South-Est Asia, the environmental degradation was severe during the recent decades in Indonesia (Sodhi et al. 2004). From 1990 to 2005, Indonesia has lost 21,32 Mha of forest (17,56% of the forest cover), with a mean rate of deforestation on the period 1990-2000 (1,78 Mha/year) three times bigger than on the 2000-2005 period (0,58 Mha/year) (Hansen et al. 2009). Even if the deforestation rates have decreased, the loss of forest still high with more than 500000ha/year lost on the period 2005- 2010 (FAO, 2010). These high rates of deforestation are due to conversion of forest in agricultural lands, commercial logging, fire and mining (Sodhi et al. 2004). 2) Importance of human modified landscapes Facing this severe forest loss, one challenge for the conservationists is the creation of new protected areas (Sodhi et al. 2004). However, the Indonesian protected areas (24Mha) varies widely in their effectiveness (Curran et al. 2004), and may be the source of dispute with local populations (Aumeeruddy 2003, Hariyadi et al. 2012) which are seen as responsible of the forest degradation by governments in tropical countries. In many cases, when protected areas are created, local populations are not allowed to carry on natural resource extraction or agricultural activities leading to conflicts with the local authorities. Moreover, in the tropical regions, 70% of the land is pastures, agriculture or a mixture
