richest communities of animals and plants in the terrestrial ecosystems Tropical and subtropical forests play an important role in human’s life and environment Forests provide wood, firewood; provide oxygen; regulate water and are the place where animals live; forests also contain many valuable and rare species of mammals, birds, reptiles, amphibians and invertebrates Terrestrial turtles and tortoises are among these species The Socialist Republic of Vietnam is ranked 9th among the most biodiverse countries of the world in terms of turtle species richness with a total of 32 species, 27 being freshwater and terrestrial and being marine (Dijk et al., 2014) Unfortunately, the conservation status of the Vietnamese turtle fauna is threatened as 85.1% of the native freshwater and terrestrial taxa are currently listed as Threatened in the IUCN Red List (IUCN, 2018) For most species, habitat loss and overhunting (for consumption as human food, traditional medicine, religious merit) have been the main threats (Stanford et al., 2018) Indeed, the forest cover in Vietnam has decreased from 43% to 36% from 1945-1990 (De Jong & Hung, 2006), although the country’s forest cover has been recently increased due to the national-scale reforestation of Vietnam since 1992 that is assumed to contribute to this recovery, the forest quality still remains poor (Meyfroidt & Lambin, 2009) Indeed, the recovery of forest coverage was due in part to the ban of industrial logging from natural areas and the displacement of wood extraction to neighboring countries, but mainly to extensive programs of homogenous tree plantations (Meyfroidt & Lambin, 2009) These plantation habitats are clearly unsuitable for turtles, whereas the suitable remnant natural forest is still heavily fragmented and isolated (Fox et al., 2004) The second main threat to Vietnamese turtles is trade for domestic consumption, with massive numbers of individuals being exploited in the 1980s- 2000s (Van Dijk et al., 2000; Nijman, 2010) also to supply the food and traditional medicine markets of China (Cheung and Dudgeon, 2006; Turtle Conservation Fund, 2002) According to IUCN (2018) assessments, the populations of most Vietnamese turtle species have declined by about 50-90% The Black-breasted leaf turtle (Geoemyda spengleri) is one of main targets of this study To protect the turtle and also forest, the world in general and Vietnam in particular, there are many laws, circulars and decrees Moreover, to carry out these Legal instruments effectively, we would need support arising from technology Nowadays, the development of science and technology as well as technical science, in particular, the advent of satellite imagery and GIS remote sensing technology supported people to make a lot in research Remote sensing data with multi-time, multi-spectral and wide-area coverage allows us to update research information quickly, effectively for saving time and effort The combination of using high-resolution remote sensing images in resource management has been a new direction for natural resources planning in general Nam Dong Natural Reserve is a protected area in the central of Vietnam The area of this natural reserve is 646,95 The area is one of the typical forest ecosystems on limestone that still remaining in the northern lowlands of Vietnam, which harbors a high level of the endemic and rare fauna and flora According to the evidence of the result of investigation, there are 18 species of animal that reported in Vietnam Redlist and Red Data Book, 2007 and IUCN Red List of Threatened Species, 2012 Recently, with the development of remote sensing and image interpretation technology, that enable users to capture, store, analyse and manage spatially referenced data of the different objects in the Earth surface Especially, the remote sensing technology has been a powerful application in distribution of turtle Moreover, the management have not been noticed that it has practical significance, be scientifically with the development, protection and management of protection turtle Therefore, I conducted the present study entitled: “Applying GIS and remote sensing to determine potential distribution area of Turtle in Nam Dong Natural Reserve, Thanh Hoa province” CHAPTER CHAPTER LITERATURE REVIEW 2.1 GIS and remote sensing 2.1.1 The concept of GIS, remote sensing and GPS Remote sensing: is the process of acquiring information about an object or phenomenon without making actual physical contact with it, as opposed to onsite observation or onsite sensing This often requires the use of aerial sensor technologies such as those used in reconnaissance airplanes and satellites in order to detect and analyze objects on the Earth, usually on the surface Remote sensing is used to receive objective information about the Earth’s surface and atmospheric phenomena thanks to sensors installed on aircraft, artificial satellites, spacecraft or in orbit station Remote sensing technology allows to record changes in natural resources and the environment making monitoring and inventory of natural resources and environment more effective Remote Sensing quickly provides high resolution digital data for the establishment and adjustment of the national mapping system and geographic database Separation of information in remote sensing can be classified into five categories: - Classification: is the process of separating and aggregating information based on spectral, spatial and time properties given by picture of objects to be studied - Dynamic detection: is the detection and operation of fluctuations based on multi-image data time - Separation of physical quantities: Extraction of natural information such as measurement of temperature, atmospheric state, height of objects based on spectral characteristics or parallax of stereoscopic images - Separation of indicators: Calculation and determination of new indices (NDVI plant index…) - Identification of natural disasters signs in service of archeological searchers GIS (Geographic Information System) that origin from three concepts geography, information, and system “Geography”: is related to spatial characteristics They can be physical, cultural, and economic and so on in nature “Information”: refers to data managed by GIS It is the data about attributes and space of the object “Systems”: is a GIS system constructed from modules Creating modules helps conveniently in management and consolidation GPS (Global Positioning System): is a satellite navigation system used to determine the ground position of an object GPS technology was first used by the United States military in the 1960s and expanded into civilian use over the next few decades 2.1.2 Landsat image Landsat satellite is the common name for the system of satellites used exclusively for the purpose of exploring earth recourse Landsat satellite system can be said to be an international satellite system The first satellite was designed to monitor the surface of the earth, Landsat-1 satellite, was launched by NASA in 1972 Originally knowing as ERTS-1 (Earth Resource Technology Satellite) Landsat, Landsat us designed as a test to test the feasibility of collecting multisprectral earth observation data Since then the program has collected abundant data from around the world Next, the satellite generations Landsat - 1975, Landsat - 1978 These two types of landsat images are only equipped with MSS (Multispectral Scanner System): an optical sensor designed to receive receive spectral radiation from sunlight shining into the earth's surface in different spectral channels, integrated by optical systems and sensors) Landsat was launched in orbit in 1982 and Landsat in 1984, both satellites were equipped with TM sensors (Thematic Mapper), used to observe the earth in spectral channels with a range from the viewing range see to infrared Landsat and were launched in 1993 and 1999 with the new improved ETM (Enhanced TM) sensor Landsat satellite was successfully launched into orbit on February 12, 2013, with the task of monitoring forest changes and ecosystems on earth suitable area The last but not least, the most favourite water species - Platysternon megacephalum is contrary to other species The largest area is the not suitable area with 348.77 ha, the very suitable area just accounts about 14.82 ha, suitablr area with 98.14 and less suitable area with 185.22 In general, Nam Dong Natural Reserve is the good habitat with great forest reserves and pretty thick river system for fresh water turtle to shelter 6.2 Limitations Study has achieved some significant results, but there are still some exist as follows: - During the implementation, study met a lot of difficulties on collecting data from the field such as lack of sample plots, unevenly plot distribution, sketchy information concerning payments for forest environmental services, instrumental error, time limitation and poor weather conditions - Limitation of data caused by the quantities of caught turtle were big so we can determine exactly where they had lived in forest - The training of sample classifying of turtle is limited - Limitation of factor affect on habitat characteristics because the study just worked on factors - The limited forest inventory parameters over the years and the documents should not assess overall health of forest 6.3 Recommendations As this study is a preliiminary survey, thus the information provided is limited Hence, further study should be carried out continuously to fill the gap in term of species ecology and to be accurate population estimated The next survey should follow the standard of line transects (selecting however additional habitats and paths in different part of the NR) to reduce the bias that will affect to result Considering to use hunting dogs as the low effort of this time searching However, it is still useful to find another species which is co-occurrence To overcome the shortcomings and achieve better results, the study has some proposals: Need to increase sample points to evaluate the accuracy; need comprehensive study of the impact of forest to the production activities of the local people, divided into more objects to get a more accurate evaluation of the forest changes during this period, need more clear images to serve interpretation 71 REFERENCES Ashton, R., Ashton, P.S., 2008 The Natural History and Management of the Gopher Tortoise Gopherus polyphemus, Report Asian Turtle Program, 2014 Turtle
