ABSTRACT

This study was conducted to provide the checklist of species of reptiles and

amphibians in Cat Ba National Park, Haiphong, Vietnam as well as the distribution, the

diversity of them in such habitats as artificial forest, natural forest, Mixed area of artificial

forest and natural forest, shrub grassland. A total of 80 species of reptile and amphibian was

recoreded within survey during July 2016 in study site: 55 species of reptile and 25 species of

amphibian. Three main methods that were used for collecting data are interview, line transect

survey, pitfall-trap. The basic data analysis indicated that reptiles and amphibians, an

important part of wildlife in Cat Ba National Park, are bringing up a lot of values to people

like food, medical values...Therefore, they have been hunted for different personal purposes in

many various ways, especially hunting. Furthermore, the living habitat of reptiles and

amphibians in Cat Ba National Park also have been threatened by 3 main threats: Pet trade

and overexploitation; Habitat loss and fragmentation; Environment pollution.. Thence, it is

very necessary to find the solutions out in order to solve these problems. The study have

recommended solutions in terms of minimizing the threats, managing, protecting and

developing the sources of reptiles and amphibians in Cat Ba National Park more effectively

and sustainability.
