INTRODUCTION

1. Rationale Located in Indo-Burma, Vietnam is one of the 34 countries known for the biodiversity and ranked as one of the 25 countries with the high biodiversity level in the world. Because of the variety of climates, terrain and habitat, the fauna of Vietnam is very diverse. The species composition of amphibians and reptiles in Vietnam increased rapidly from 340 species in 1996, 458 species in 2005, and 545 species in 2009 and in 2016 the number of it was 650. Besides the diversity of species composition, the herpetofauna of Vietnam is also endemic with 48 species of reptiles and 33 species of amphibians. The previous researches on amphibians and reptiles in Vietnam just focused on the mountainous area and the Annamite Range. These studies were rarely carried out in the South Central region. Phu Yen has an area of 116.819 ha of natural forest making up 31,1% and the quality of the forest is good. However the study on amphibians and reptiles in Phu Yen Province is very limited. There were a few related works published such as Campden-Main (1970) recorded four species snakes; Nguyen Van Sang et al. (2005) recorded 10 species of amphibians and reptiles; Ngo Dac Chung and Tran Duy Ngoc (2007) recorded 71 species; David et al. (2008) described a new species of ocellatus; Nguyen et al. (2009) recorded 17 species of amphibians and reptiles; Zieger et al. (2013) discovered a new Cyrtodactylus kingsadai in Dai Lanh. To update the list, evaluate the diversity and the conservation value of amphibians and reptiles species in Phu Yen. We have chosen the theme “Research on the species diversity, distribution and conservation value of amphibians and reptiles species in south part of Cu Mong Pass, Phu Yen Province”. 2. Research objectives Determine the species diversity, distribution and conservation status of the amphibians and reptiles in the south part of Cu Mong Pass, Phu Yen Province. 3. Research contents - Determine the diversity of species composition.

CHAPTER ONE LITERATURE REVIEW

1.1. Overview of research on amphibians and reptiles 1.1.1. Vietnam According to Nguyen et al. (2009), researches on amphibians and reptiles in Vietnam were conducted long time ago but flourished in the late 19th century, especially in the early 21st century and developed in several different ways: - Researches on the diversity of the species composition of amphibians and reptiles Most of the researches on amphibians and reptiles in this direction were concentrated in the mountainous areas of the Annamite Range and the Central Highland. The subjects of these studies focused on the less studied groups, such as genera belongs to the family colubrids (Amphiesma, Oligodon), family (Cnemaspis, Cyrtodactylus, Gekko), family skinks (Scincella, Sphenomorphus, Tropidophorus) and other amphibians species (Ichthyophis, Leptolalax, Leptobrachium, Gracixalus, Philautus, Rhacophorus, Theloderma). - New species discoveries of amphibians and reptiles from Vietnam and taxonomic changes After Nguyen et al. (2009), from 2010-2016, 97 species and numerous taxonomical of amphibians and reptiles amendments were discovered by applying molecular biology techniques for classification researches. - Studies on biological characteristic, ecology and application There were a lot of researches on the morphological and ecological characteristics of amphibians and reptiles species: fasciatus, Leiolepis belliana, Leiolepis reevesii, Ptyas korros, Ptyas muscosa, Hemidactylus frenatus, Gehyra mutilata. In recent years the researches on acoustic studies, tadpoles of amphibians species and the rare species of amphibians and reptiles have been expanded. Many species in acoustic fields were recorded such as Hylarrana guentheri, Feihyla vittata, Polypedates megacephalus, Microhyla marmorata; the tadpole morphology of species are described including Microhyla marmorata, Rhacophorus

3 maximus, Megophryidae; and researches on the rare species were of interest such as Mauremys annamensis, Shinisaurus crocodilurus. 1.1.2 South Central of Vietnam There is a little of work on amphibians and reptiles species composition in South Central region except the work of Geissler et al. (2011) in Binh Thuan and Duong Duc Loi’s dissertation (2016) which was conducted in northern Cu Mong Pass, Binh Dinh Province. However after Nguyen et al. (2009) there were many new species of science discovered in this area. That means the diverse of amphibians and reptiles in this region are very potential. 1.1.3 Southern Cu Mong Pass, Phu Yen Province Campden-Main (1970) recorded 4 species of snakes; Nguyen Van Sang et al. (2005) discovered 10 amphibians and reptiles species; Ngo Dac Chung and Tran Duy Ngoc (2007) recorded 71 species; David et al.(2008) described a new type of snake named Oligodon ocellatus; Nguyen et al. (2009) recorded 17 species, Zieger et al. (2013) discovered a new Cyrtodactylus kingsadai in Dai Lanh. The results of the work show that 73 species of amphibians and reptiles are recorded in Phu Yen, including 21 species of amphibians and 52 species of reptiles. 1.2.

Remarkably, there were nine species discorvered in Phu Yen in the last five years: Kalophrynus honbaensis, Kaloula indochinensis, Microhyla mukhlesuri, Theloderma vietnamense, Ichthyophis nguyenorum, Calotes bachae, Cyrtodactylus kingsadai, Dixonius minhlei, Oligodon cattienensis. 3.1.3. The species with the taxonomic changes Compare with the documents of Ngo Dac Chung and Tran Duy Ngoc recorded in Phu Yen in 2007, there are some taxonomic changes: - The class of Amphibians: Limnonectes blythii: this species doesn’t exist in Vietnam. Limnonectes kuhlii: this species is redefined as L. bannaensis. Limnonectes kohchangae: this species is redefined as L. poilani. Polypedates leucomystax: this species doesn’t exist in Vietnam. The samples from Phu Yen were considered as P. mutus. Ichthyophis bannanicus: this species is identified as I. nguyenorum. Rhacophorus annamensis and R. exechopygus: these two species have the same morphology. Based on the collection of amphibians and reptiles in 2015-2016 in Phu Yen province, we could only confirm the existence of R. annamensis. - The class of Reptiles: Gekko ulikovskii: this species is considered as G. badenii. Cuora galbinifrons: the previous record of this species in Phu Yen Province was identified as C. picturata. 3.1.4.

The priority activities for conservation - Protection for the habitat of amphibians and reptiles species such as forest protection; enhancement of the work of greening the vacant land and modern equipment for the forest rangers to protect forest; forest fir control; conversion of cultivation methods. - Sustainable harvest of the resources of amphibians and reptiles: Hunting control in the strictly protected forest . - Propagation of awareness and livelihood creation for people.

CONCLUSION AND RECOMMENDATION

1. CONCLUSION 1.1. The diversity of species composition: We recorded 135 species comprised 38 species of amphibians belonging with 24 genera, 7 families, 2 orders and 97 species of reptiles belonging with 61 genera, 18 families, 3 orders in the south part of Cu Mong Pass. In this thesis we also additionally recorded 63 species for the herpetofauna in Phu Yen, 24 species for the South Central region and Lycodon cardamomensis species recoreded for the first time in Vietnam. This study provides the morphological characteristics of 63 additionally recorded species in Phu Yen Province and 2 unnamed sciencific species based on the collected specimens. 1.2. Distribution characteristics: According to the study area: The number of species recorded from Tay Hoa district is highest (85 species), followed by Song Hinh district with 63 species, Dong Xuan district with 45 species, Son Hoa district with 44 species, and Song Cau district with 16 species. According to the altitude: Most of the amphibians and reptiles were recorded at the hight of 300-400 m (87 species). This is the hight which has the the relatively large area of natural forest and good forest quality and be suitable for the species of amphibians and reptiles. According to habitat: The largest number of species is evergreen forest with 96 species. This habitat is the home of many rare and endemic species. 23

1.3. The similarity of species composition: The south part of Cu Mong Pass, Phu Yen Province and the north part of Cu Mong Pass, Binh Dinh Province have the average level of similarity of the species composition of amphibians and reptiles. This means Cu Mong Pass is not the boundary of geographical distribution of amphibians and reptiles between these cities. The most different from the provinces in the South Central area is Binh Thuan province. 1.4. Conversation issues: Conservation value: We have recorded 29 rare species. Based on IUCN Red List of Threatened Species (2016), there are 4 Critically Endangered, 4 Endangered, and 7 Vulnerable. Arcording to Vietnam Red Data Book (2007) there are 6 Critically Endangered, 7 Endangered, and 9 Vulnerable. We also recorded 32 endemic species with the conservation value (16 species for Indochina and 16 for Vietnam). Factors afftecting the fauna of amphibians and reptiles: deforestation for milpas, the illegal logging, the migration of the northern compatriots to the new economic zones, the hydropower project or the road construction, and the downturn in natural habitat. 2. RECOMMENDATION 2.1. Further study: Researches on biological and ecolofical charactersictis of species which have the commercial value such as Leiolepis guttata, Physignathus cocincinus, Varanus nebulosus, Varanus salvator, Ptyas mucosa 2.2. Recommendations of conservation plannings Priority sites for conservation: Evergreen forest in Tay Hoa district, Song Hinh district are the most important areas because the forest quality is good, the number of rare and endemic species is highest in the province. In these regions, the establishment of nature reserve or species management area should be planned to protect the natural landscape as well as biodiversity values in Phu Yen province. Sustainable use of amphibians and reptiles resource is associated with economic development, such as establishment of fishing criteria, the recommendations that people should not use the forms of the spent fishing (the electrofishing) to hunt the species of amphibians and reptiles. Enhancement of public awareness of state’s policies and laws and the long-term benefits of forests are necessery.
