Trang 10CHAPTER 1 INTRODUCTION
Vietnam has an abundant of animal resources with high endemism This is a big advantage in strategies of protecting and developing biodiversity in our country This resource brought us benefit in many aspects of live Previously, rainforest wildlife are one supply of food and rare pharmaceuticals Besides, many products from wildlife animal were used to produce craft items which are very popular Another important role of wildlife is in science and medicine Some animals are extremely rare resources in understanding the principles, biomechanics, physiology to serve the prevention and medical care for people Wildlife animal resources, especially gene bank is very precious, is the origin of current domestic animals, along with the balancing factor of current ecosystem
Reptile and amphibian are other valuable resources beside birds, mammals and fishes
In natural ecosystem as well as humanity ecosystem of our nation, reptile and amphibian play
an important role in social
A serious problem now is the wildlife animal sources in general and the reptiles, resources in particular are endangered of decreasing sharply A lot of species are becoming rarely, or special rarely, some species are threatened of becoming extincted The main reason that leads to this situation is the over-exploited that made the area of forest soil decrease and some species are lost their habitat The illegal hunting with the inefficient management of functional agencies also need to be cared and adjusted
Red data list is the inventory of the global conservation status of all biological species, which is abbreviated to IUCN ( International Union for Conservation of Nature and Natural Resources) The levels of extinction risk in Vietnam red data book are similar to those in IUCN Red list Up to now, the list has evaluated over 79,800 species that may come to extinction according to categories
Trang 11The latest released list in 2007 shows that there are 418 endangered species of animals according to risks of extinction The number consists of 40 of reptiles and 13 of amphibians (Vietnam Data Red Book, 2007)
CITES is The Convention on International Trade in endangered species of wild fauna and flora is a multilateral treaty to ensure that international trade in specimens of wild animals and plants does not threaten the survival of the species in the wild CITES contains 5,000 animal species and 25,000 plant species, and is divided into 3 appendices I, II, III with different levels of being threatened to existence species
The decree No 32/2006/ND-CP dated 30/03/2006 is a government decree on Management of endangered, precious, and rare species of wild plants and animals It has classified wild, precious and rare animals into 2 groups according to the risk of extinction and the protection of law towards these species The two groups are: Group IB (Prohibiting exploitation and use for commercial purposes, including wild plants, animals, for which populations are very small in the wild or are in high risk of extinction) and Group IIB (Restricting exploitation and use for commercial purposes, including wild plants and animals, for which populations are small in the wild or are in risk of extinction) Group IB includes 62
species Of them, there are 11 species belong to class of reptilia such as Desert Cobra (Ophiophagus hannah Group IIB includes 89 species and of which are such reptile species
as Indian Rock Python, Radiated Ratsnakes, etc
In the past two decades, several herpetological surveys have been carried out on Cat
Ba Island In his zoological analysis, Bobrov (1993) recorded 18 lizard species from islands in the Gulf of Tonkin including Cat Ba Island Darevsky (1990) studied the herpetofauna of some Vietnamese offshore islands and listed seven species of reptiles for Cat Ba This number was distinctly increased by the eight-day survey conducted by Nguyen & Shim (1997), who reported of 20 species of reptiles including two species of marine turtles In view of this
Trang 12increasing number of new species records on the one hand, and a still low species number compared with northern mainland Vietnam on the other, we decided to conduct additional herpetological field studies on Cat Ba Island These led to the discovery of new species of Goniurosaurus (Ziegler et al 2008) and Sphenomorphus (Nguyen et al 2011)
To protect and develop this valuable natural resources, the Government in recently have had many optimistic policy and solutions Beside the legislations, we also have special use forest system are managed by local to center and have got positive results To make basis , materials for natural resources preservation , contribute to protection and development
of wildlife animals in general and reptiles, amphibians resources in particular, I am
proceeding to research the topic " The Diversity of Reptiles and Amphibians in Cat Ba National Park, Haiphong, Vietnam"
Results collected from this study will be used for planning and preparing technical measures to manage, protect and develop the biodiversity effectively

- Cat Ba National Park is first park that have subzones of forest and marine ecosystem
- Cat Ba National Park is divided into three functional areas: the subdivision of strict protection zone (4,914.6ha), the subdivision of ecological rehabilitation area (11,094ha), service administrative subdivision (91.3ha)
3.2 Climate and hydrology
Cat Ba National Park is located in the tropical monsoon area, influenced many of the coastal line climate - Average annual temperature: 20oC; Average annual precipitation is:
1700 - 1800mm Rainy season from April to November and dry season from December to March next year; Average annual humidity is 85%; April is wettest and January is driest; Average annual evaporation is 700mm per year; monsoon northeast wind from September to March next year, the southeast wind from April to August; an average of 2-3 storm a year
3.3 Topography
All of Cat Ba island are mountainous areas with elevations between 50-200m, the average slope is 30-40 degrees; the lowest place is Ang Tom, 10-30m below sea-level; the highest place is Cao Vong peak located in the north of the island, about 331m high Main terrain of Cat Ba is limestone alternating with many large and small valleys In terms of mineral resources, in addition to limestone, Cat Ba Island also has valuable mineral water (Xuan Dam commune has hot mineral water mine with temperature of 38oC) Cat Ba’s typical
Trang 15ecosystems are tropical rain forests on limestone mountains mangroves, coral reefs, sea grass, cave ecosystem, etc
3.4 Geology and geomorphology
3.4.1 Geologic characteristics
- Cat Ba area as well as the Northeast Vietnam has a history of lasting geological development, had been a part of the folded structure Caledonia marks the end geosynclinals regime deep sea Karatzia in late Silurian
- The limestone blocks with an average age of carbon Late - Permian (250-280 million years) There is configuration blocks, sometimes stratified pretty thin, gray or white-gray alternating with silicon limestone They are full shape of a Karst domain submerged of sea, due to the impact of surface water and groundwater has created a system of caves in different heights (4 meters, 15 meters and 25-30 meters) Due to the activities of the ocean waves has created waves in all limestone foot of Cat Ba Island and the porches abrasive long shape and narrow surrounded, with the dual wave at 3.5-4.0 meters and 1.0-1.5 meters
3.4.2 Soils
- Survey results field work, mapping land II, shows the internal and external communal of Cat Ba National Park because bedrocks mostly limestone with Karst topography conditions and humid tropical climate, so have formed the main soil types are as Red-brown soil Feralit developed on limestone (Fv); Soil Feralit sepia slopes capacitors of the foot of a mountain limestone (Tv); Soil Feralit fawn develop from the product of weathered limestone mixed (Th); Alluvial sour salt (Db)
3.5 Fauna and Flora
Trang 16-Terrestrial animals about 282 species, especially species of golden langur (Trachypithecus poliocephalus), this is beasts species particularly rare in the world only remains in Vietnam (about 50-60 individuals, according to the IUCN Red List)
- Marine animals: there are 98 species of zooplankton, 196 species of marine fish (including 79 species of reef fish), 177 species of coral, 532 species of bottom animals According to survey data of the Institute of Oceanography in Hai Phong, said today there are
900 fish species, 500 species of molluscs, 400 species of crustaceans In total number of marine species in the area of Cat Ba has found there are 21 rare species, including two species listed in the CITES list, 7 species in the Vietnam Red Book need protected still exist in the region
3.5.2 Flora
- Flora resources on Cat Ba island abundant with statistics of 620 species belonging to
438 genera and 123 families The typical family: Myrtaceae, Moraceae, Rubiaceae, Lauraceae, Asteraceae
-Plant composition in Cat Ba not really abundant, but still much value crops economically and science as: Fagraea fragrans, Chukrasia velutina, Aglaia spectabilis, Podocarpus fleuryi The most typical of the type of vegetation in Cat Ba Island is the type of evergreen rain moist forest on limestone, and mangroves forest vegetation type coastal, estuaries Additionally, in areas still appear some specific forest types and rare, it is kind of submerged vegetation in high mountains
- In addition to the forest vegetation, agricultural vegetation type also plays a key role in the region This vegetation including: plantation forests, perennials, agricultural crops, fruits, aquaculture and residential areas
3.6 Economy-Society
3.6.1 Population and employ
- According to statistics in 1997, the Cat Ba district population is 27,051 people, accounting 1.6% of the total population of the city of Hai Phong The average population density of the district is 80 people/km2
Trang 17- The number of people in labor age is 10,500 people (1997), 12,000 (2000) and 15,000 people (2010)
- According to the Statistical Office of Hai Phong city, population increase in the area
of Cat Ba Island mainly is natural increase with an average of 0.68%/year (2011), lower than the annual average rate of Hai Phong city and the country Relatively stable population in recent years, the phenomenon of migration freely to the island Total population of the region
as of 2011 was 16,566 people, the proportion of men and women in the past years without significant changes, the percentage of women than men usually a little higher According to statistics in 2011, the percentage of women in the region accounted for 50.69%
3.6.2 Livelihood
3.6.2.1 Production of industrial and handicraft
- The small engineering works, repairing boats, stone production, mineral water, production of building materials, electricity, rapidly developing produce timely service and create Occupations for thousands of workers
- In general, industry and handicraft development less powerful, scattered and focused
in town
3.6.2.2 Agricultural production
- Cat Ba island is limestone terrain, so largely lacks surface water The commune on the island with an area not exceeding 200 ha of agricultural land The rice output is not high,
so do not meet people's demand for agricultural communes as well as people on the island
Agricultural production sector accounts a very small proportion of the economy of the district (all district only occupy 1.5% of the total production value and 2.3% of GDP in the district)
3.6.2.3 Economic forest
- Due to the forests area on the island of Cat Ba majority belonging to management area of the national park management board, so the area of forest land in the area of the buffer
Trang 18zone is not much So far, FPU of district was coordination with FPU of national park guided perform some work such as: reforestation focus, scattered plantations, restored forests and
forest care Cat Ba island has a forest area of 15,200ha, of which forest land managed by the
National Park is 9,800 ha, remaining 6,400 ha is managed by the cooperative Natural wood forest has about 293 ha (shrubs forest) Plantations: resinous pine (126 ha), Acacia (66 ha),
Cunminghamia lanceolata (30 ha), Bamboo (40 ha)
3.6.2.4 Fishery Exploitation
- Cat Hai district has 288 fishing ships with a total capacity of 3120 CV, exploitation output 3,944.7 tons of shrimp, fish of all kinds (2011) For offshore fishing ships, fishing grounds mainly are offshore region

This study was conducted between January and August, 2016 The thesis proposal was written up from January to June as well as preparing equipment, knowledge, document for collecting data in the field In the period of July, 5th and 22th, the field work (collecting data) had been running Then, this study have analyzed data and finished in September, 2016
4.1 Secondary document
- Before go collecting data, the author did write thesis proposal, learn about study site
through documents, previous researchs that related to infomations of study site and amphibians such as natural conditions, maps, lists of reptiles-amphibians have published
reptiles-4.2 Collecting data methods
4.2.1 Interview method
Before going to interview, it is very necessary to prepare things following:
- Questionaires
- Pen, notebook, recorder,
4.2.1.1 Interview the rangers and Cat Ba NP staff
This study had interviewed 5 rangers and 3 staffs of Cat Ba NP
- Goal: To collect the information about the sources of reptiles and amphibians, where
they appear mostly, when they appear mostly, the status of hunting rare reptiles and amphibians
- Objects: officials working for conservation projects, scientific department, rangers of Cat Ba National Park
- Content: The interviewee would be asked with prepared questions that related to the status of reptiles and amphibians, threats to their lives
4.2.1.2 Interview the hunters and local people
The study had interviewed a total of 15 people including 4 hunters and 11 local people
Trang 20- Goal: To collect the information about the species they meet daily as well as the time
and location; How they catch reptiles-amphibians and what they catch for
- Objects: Local people and hunters randomly in line transect
- Content: The interviewee would be asked with prepared questionaire that related to the reptile and amphibian species they meet; do they catch or not and for what; the price of reptiles and amphibians catched for sale
4.2.2 Line transect survey
4.2.2.1 Preparation
Transects establishment principles:
- Designing transects spend the priority on where are easy to be recognized and approached such as path, areas that have high humidity or streams
- The length of transects from 2 to 3 kilometers, the distance between transects is 500m up
to types of habitats and terrain, the distance from transects to road must be 25m at least
- The transects are created based on topographic map, vegetation and actual experiment
- The transects must include the typical and various habitats, topographic types of study site Each transect is marked by trees or others
According to principles above, in this study, researcher created 4 transects through 4 main habitats: Artificial forest; Natural forest; Mixed area of artificial and natural forest; Shrub grassland
Trang 21Figure 4.1 Line transects for collecting data in Cat Ba National Park
4.2.2.2 Performance
- The investigation was carried out on schedule as the timetable above The researcher started at beginning point and moved with speed of 1-2 km/h During moving, pay attention
to look and hear sounds of reptiles and amphibians very carefully
- The investigation time was divided into 3 periods of day: 8h-11h, 13h-17h and 23h (use flashlight) to determine the appearance of reptiles and amphibians in various times
19h-of day and which period they appear the most
- If detect an individual, the researcher would use the bat or hand (up to specific
species) to catch and put into bag Note: just take only 1 specimen respresenting for 1 species
to record the info as aspect, size
- To preserve the specimen, put the trapped species into 90o alcohol Especially, with big individual, need to operate and take off all their viscera then wash by water and alcohol Then put into 90o alcohol
Trang 224.2.3 Pitfall-Trap
4.2.3.1 Preparation
To do this method, the researcher did had to prepare some tools and equipments like:
- Buckets with radius of 15-20cm and the 40cm depth
- Nylon, plastic barrier, GPS
- Buckets would be buried under the ground with top edge are parallel with the ground surface The distance between the traps is 1-2m and traps are connected by a plastic barrier
Traps are set at lot of different habitats, the distance between them is 50-100m Note: Have to
create habitat for reptiles and amphibians by putting water and dry leaves into bucket avoiding that they may jump out
- Check out the traps everyday to avoid that species could be trapped and died
- When taking the animals out of the trap, use iron pair (or gloves) to pull lumbar of the species and take them out very carefully and slowly, then specimens preserved in alcohol
90o, put on the storage awaiting classification, accreditation While the specimens are alive, researcher can take photo using as documents
4.3 Data analysis
- To analyze the raw data, this study have used some software such as Microsoft-excel,
Microsoft-Word, Arc-gis, Google earth for making table; drawing maps, chart
- Use list of endangered species like IUCN, Vietnam Redbook, Decree 32NĐ-CP in order to indentify conservation value of species
Trang 23- Use the terms of Threat Reduction Assessment for Conservation to rank the threats to
reptile and amphibians in Cat Ba NationalParrk In order to do that, the study follow these steps below:
Step 1: Define the project area in space and time
Step 2: Develop a list of all threats
Step 3: Define the threats and what 100% reduction means for each
Step 4: Rank each threat for area
Step 5: Rank each threat for Intensity
Step 6: Rank each threat for Urgency
Step 7: Add up the ranking scores
- This study have listed 3 main threats to reptile and amphibian in Cat Ba NP: Pet trade and overexploitation; Habitat loss and fragmentation; Environment pollution
Trang 24CHAPTER 5 RESULTS AND DISCUSSION 5.1 The composition of reptile and amphibian in Cat Ba National Park
5.1.1 The results of investigation
Based on data collected from such sources as interview, line transect survey, trap, observation in both field and specimen room, the checklist of species composition have been recorded 80 species of reptile and amphibian belonging to 21 families and 3 orders in Cat Ba National Park The detailed results of reptile and amphibian species were shown in the Appendix 5 and summaraize in table 5.1

Trang 265.1.2 Assessment of taxon diversity
The assessment of reptiles and amphibians diversity in Cat Ba National Park are shown in charts below:
Figure 5.2 The diversity of reptiles in Cat Ba National Park
Based on data of the pie chart, it is very easy to see that the total species of Colubridae
is the greatest (35%) Dibamidae, Lacertidae, Varanidae, Typhlopidae, Boidae,
Geoemydidae, Cheloniidae are families that have least number of species
Trang 27Figure 5.3 The diversity of amphibians in Cat Ba National Park
Based on data of the pie chart, it is very easy to see that the total species of
Microhylidae and Dicroglossidae is the greatest (24%) , are families that have least number
of species
Thence, the species that have large ecological amplitude are less threatened to be prey
by hunter and vice versa It means that species with small ecological amplitude have to face with high risk of extinction
5.2 The distribution of reptiles and amphibians by habitats
At study site, this subject focus on 4 main habitats for collecting data of reptile and amphibian that are Artificial forest (H1), Natural forest (H2), Mixed area of Artificial forest and Natural forest (H3), Shrub grassland (H4) and the result is shown in the chart following:
Trang 28Figure 5.4 The number of species detected in each habitat
According to the data in table, the habitats of natural forest have highest diversity with
17 species detected, the habitats that have smallest diversity are Artificial forest with 8 species detected Thence, each of species reptile and amphibian lives in different habitat adaptively Some species just found in 1 or 2 habitats For instance, Guenther’s Frog, Mao-son Frog The difference of living conditions could be the reason for the differene of species found in each habitat To be more details, natural forest, habitat with less influences from human and good living conditions, would has high diversity of species as well as shrub grassland and mixed area Artificial forests are areas that have been affected significantly by human activities such
as hunting, trapping so the diversity on species composition is very poor This means a lot
in researching the impact of environment to species living inside
