MINISTRY OF AGRICULTURE AND RURAL DEVELOPMENT VIETNAM FORESTRY UNIVERSITY STUDENT THESIS Title ASSESSMENT OF STATUS OF EXPLOITATION AND TRADE OF TAM DAO SALAMANDER (Paramesotriton deloustali Bourret, 1934 ) IN TAY THIEN, TAM DAO NATIONAL PARK Major: Natural Resources Management Code: D850101 Faculty: Forest Resources and Environmental Management Student: Nguyen Thi Ha Student ID:115 309 1138 Class: K56 Natural Resources Management Course: 2011 - 2015 Advanced Education Program Developed in collaboration with Colorado State University, USA Supervisor: Dr Dong Thanh Hai Ha Noi, 10/2015 Abstract Tam Dao salamander (Paramesotriton deloustali), also known as Tam Dao newt, an endemic amphibian to the mountains of Vietnam It is listed as vulnerable (IUCN, 2015), in group IIB of species that is restricted to exploitation and trade under commercial purposes in Decree No 32/2006/ND-CP of Vietnam government The status of exploitation and trade on this species is increasing as a profound matter due to the fast growth of eco-tourism in Tay Thien area in recent years Besides that high profit from illegal trade, lack of knowledge, ineffective policy implementation and enforcement are additional drivers of this trend The aims of this study are 1) investigate the status of P.deloustali population and its main threats, 2) investigate how this species are being exploitation and trade, and 3) determine factors that drive the participation of locals in trade and harvest this animal in recent years Results show that the status of Tam Dao newt population declined significantly in the period of 10 years up to now The top ranked threats that led to this trends were waste from tourism activities, construction, and illegal harvest and trade The status of harvest and trade of this endemic species had taken place in this area for a long time ago with very sophisticated trading flow and form of hiding to avoid the discoverable of authorities The period after establishment of Tam Dao national park (1996-2010) was reported as the hottest time of exploiting and trading The primary motivation for hunt this species was for sale instead of for subsistence use as mentioned in some literatures 10 sale points with totally 31 individual of Tam Dao salamander was observed during the study, even in a short period of time and in low tourism season Thus, the study concludes that the status of exploitation and trade of P.deloustali is popular in Tay Thien area In addition, there are four factors are proven to influence in the participation of people in hunting and trading of this species are: sex, educational level, markets, and livelihoods Among these factors sex and markets provide strongest effect in process of making decision Acknowledgements This report is submitted for the Advanced Education Program Developed in collaboration with Colorado State University, USA, faculty of Forest Resources and Environmental Management, Vietnam Forestry University This study would

Wildlife trade is becoming a big business, in Vietnam and other Asian countries Illegal trafficking in wildlife in Asia is almost beyond control Wild animals are hunted, killed and captivity on a large scale, in order to satisfy the huge demand for bush meat, fur, traditional medicines derived from wildlife, livestock and pet needs (Nguyen Van Sang et al., 2003) Some animals are at risk of near extinction, others are becoming increasingly rare Therefore, it is raising the need for research to sustainable conservation management Tam Dao salamander (Paramesotriton deloustali), also known as Tam Dao newt, is an endemic amphibian to the mountains of Vietnam According to IUCN Red List of Threatened species, Tam Dao salamander is listed as VU It is also listed in group IIB of Decree No 32/2006/ND-CP of Vietnam government of species that is restricted to exploitation and trade under commercial purposes Since 1992, Tam Dao newt has listed in Vietnam Red data book (Ministry of Science and Technology 1992) that only can be found in Vietnam, and it is in level B (near extinction) Tay Thien is a famous historical, scenic tourist attraction of Tam Dao NP, because it meets all three factors: culture, religion, and beautiful natural landscape Therefore, it not only attracts tourists in high season, but all year around In recent years, the tourism boom has brought many benefits to the local economy, but partly destroyed the natural beauty, caused environmental pollution and lost biodiversity of Tam Dao NP, and the surrounding area According to the herpetological survey report (Nguyen Quang Truong et al., 2004) the population of Tam Dao salamander are mostly detected in Dai Dinh commune in Tay Thien area Therefore, tourism activities might lead to various impacts on Paramesotriton deloustali (P deloustali) population in either its habitat or population size and richness The Global Amphibian Assessment (IUCN, 2015) reported that P deloustali was used at subsistence level for food (human), at subsistence level and nationally for medicine (human and veterinary) and nationally and internationally for pets/display animals They estimated that 0-25% of specimens in commercial trade were wild-sourced The trend in the level of wild offtake/harvest in relation to total wild population numbers over the last five years was reported to be increasing (IUCN, 2015) Nguyen Van Sang et al., (2003) reported that in northern Viet Nam, P deloustali was sold at local markets and in villages for pets; that the dryform was used as a traditional medicine to cure diseases such as asthma and rickets; and that the species was rarely eaten by local people, apparently because of its bad smell and strange body form The local pet trade was thought to be the main reason for the decreasing population at Tam Dao National Park (Nguyen Van Sang et al., 2003) Therefore “Assessment of status of exploitation and trade of Tam Dao salamander (Paramesotriton deloustali Bourret, 1934) in Tay Thien; Tam Dao National Park‟‟ is vital important The aims of this research are to: 1) investigate the status of P.deloustali population and its main threats, 2) investigate how this species are being exploitation and trade, and 3) determine factors that drive the participation of locals in trade and harvest this animal in recent years Thus, this study will play a role as a basic for proposing better management measures, and effective biodiversity conservation of P deloustali in Tam Dao NP, as well as its buffer zone 10 Spring (from Jan to Mar) Autumn
