Summary of theses so far completed by masters students supported by the Darwin Initiative Project on Endemic Annamite Ungulates 17-008. NB: For theses completed at a UK university, the abstract from the thesis is included. Theses completed at Vietnamese universities do not typically include an abstract and a summary is provided by the Darwin Project Officer. Nguyen Trong Dong (2011) Use of forest mammals in the Pu Huong Nature Reserve. Master’s Thesis in Zoology, Vinh University, Nghe An Province, Vietnam. (In Vietnamese). Thesis summary by NMW This thesis aims to describe the composition of the forest mammal community in the nature reserve, to enumerate different wild animal products and methods of hunting of wild mammals, assess the impact of communities on wildlife resources in the nature reserve and evaluate the status of proposed management measures. The work is based on fieldwork from January to June of 2010 in all 5 districts around the nature reserve (Quỳ Châu , Quế Phong, Tương Dương, Con Cuông & Quỳ Hợp). In each district surveys were conducted in one village (2 in Quy Hop) and in the district town. Field surveys, including spotlighting, are also conducted. The thesis lists the mammal species occurring in the reserve, based on literature review, and describes which species are used by local people, and for what, on the basis of interviews conducted by the author. Use is confirmed for 48% of the species known from the reserve, however it should be noted that this is certain to be an underestimate because use of many specific species, especially bats, rodents and ‘insectivores’ cannot be confirmed through interviews. The information on wildlife trade is probably the most significant for conservation, including a summary of the numbers of wildlife restaurants in the district towns and the extent of their daily consumption, measured in total weight and number of individuals for each species. Mention is also made of similar statistics for restaurants in Vinh city, the provincial capital. The thesis also lists trophies found in each district and discusses other impacts from local people on forest mammals, including logging, encroachment and NTFP collection. The list of species for the reserve is based mostly on literature review but also includes data from field survey, including spotlighting. Noteworthy sightings claimed for field surveys include the mustelids Lutra lutra, Mustela strigidorsa and Arctonyx collaris. Unfortunately, this thesis does not give too much detail on the specifics of the methods used. It should be noted that the author worked as a team with Pham Thi Huyen, whose thesis gives more detail on some of the methods (e.g. locations of transects) which are probably also valid for this work. Luong Van Duc (2011) Research on distribution, model development and recommendations for patrols for 3 species: Saola, Large-antlered muntjac and Truong Son muntjac in the Saola Nature Reserves of South Thua Thien Hue and North Quang Nam. Master’s thesis in Environmental Science, Hue University of Science, Hue, Vietnam. (In Vietnamese) Thesis summary by NMW This thesis aims to provide recommendations for priority patrol areas to protect Saola, and also to assess the value of such a prioritization for other endemic ungulate species present in the area. It is based on community mapping data, using the ‘beaning’ method (see community mapping manual) with groups of peole knowledgeable about the forest from each village. Data were collected from 26 villages of Katu people in the communes of Thuong Long, Thuong Quang, Thuong Nhat, Huong Huu, Nam Dong district, Thua Thien Hue. Because some of these communes, especially Thuong Long and Huong Huu, use a wide area of forest, information is provided, through this method, to the whole Hue-Quang Nam Saola conservation landscape, not just Nam Dong. The community mapping bean data are digitized and data on each species are combined across the different villages. Beaning data on the forest areas used by each village are also collected and compiled as an indicator of how well each village knows each area. Quality of information maps are compiled based on the number of villages reporting on each area. A systematic conservation software package (Zonation, Moilanen et al 2005) is used to perform the prioritization and sensitivity analyses are used to explore the effects of selectively removing the most uncertain data and of varying assumptions about Saola range size and vulnerability to hunting. The study notes that local people consistently report that Saola are much declined and now rare. The prioritization of forest compartments for Saola conservation leads to the conclusions that: 1) High priority of the Thua Thien Hue Saola NR overall, relative to the other two PAs, 2) Within this TTH Saola NR, compartment 352 in the southwest and also 347, in the northwest are prioritized. 3) In Quang Nam, areas in BHallee (compartments 12&13) are prioritized, rather than the area in north A Vuong, prioritized by some other assessments. 4) In the Bach Ma extension, compartments 430 & 429 are prioritized over compartment 410. The sensitivity analysis shows these conclusions to be robust except that (re point 3 above) north A Vuong is prioritized when Saola are considered wide-ranging and vulnerable to threat because of the importance of maintaining larger contiguous areas under these conditions (North A Vuong links priority areas in the TTH Saola NR and the Bach Ma extension) The ‘truong son muntjac’ appears to be commoner and more widespread than Saola. No conclusive data could be gathered on the Large-antlered muntjac. Interestingly, a type of muntjac recognised by people from Huong Huu seems to match the description of the hog deer, presumed regionally extinct, but no specimens were available. NB: The author collected data on all ungulate species but only analysed data on endemic ungulates. Ta Dinh Thanh (see below) collected comparable data on all species from other, contiguous areas and Luong Van Duc and Nicholas Wilkinson have written a draft report combining these two datasets, but without the Zonation analysis with its consideration of sensitivity and uncertainty. Nguyen Thi Thu Hieu (2011) Research on patterns of forest product use of people of the Katu ethnic group in Nam Dong district, Thua Thien Hue. Master’s thesis in Environmental Science, Hue University of Science, Hue, Vietnam. (In Vietnamese) Thesis summary by NMW This thesis aims to give a spatial overview of the use of forest products by local communities in Nam Dong, using data from villages in Thuong Long, Thuong Quang, Thuong Nhat, Huong Huu communes. The thesis also discussed the importance of forest resources to local livelihoods and the use of indigenous knowledge in management of forest resources The main method is community mapping, using the beaning method (see manual), of places where the most important and valuable forest products are collected. Community mapping groups were a stratified pseudo-random sample of 12 people, men and women from poorer and wealthier households in each village. In addition, the following methods are used: 1) “Freelisting” of forest products 2) “Pilesorts” to rank forest products in order of importance 3) Tree diagrams for markets of forest products 4) Seasonal calendars 5) Further, individual, semi-structured interviews. The forest products considered are rattan, wild meat, timber, honey, la non, fish and vegetables. The study deliberately does not attempt to distinguish between different sub-categories of these products and no distinction is made between high-value and low-value timber. Subsequent GIS analysis aims to: Identify focal areas of forest product exploitation by local people in the district Examine spatial patterns of diversity (Shannon index) in forest product harvesting. Explain patterns in intensity of exploitation in terms of slope, altitude and distance from the residential area in the centre of the district. The results show that, in general, forest products are collected in the most accessible areas possible: closest to the villages, least slope and lowest elevation. Diversity of forest products harvested is also highest in these areas. However the exceptions are wild meat, rattan and honey. For each of these products, the harvesting levels appear to peak at some distance from the village. Correlation analyses demonstrate and the results clearly presented in maps based on linear combination of weights. Of the forest compartments within protected areas in Nam Dong, it is those in the Bach Ma extension, particularly 430, 429 and 427 (Ba Con, Ma Rai and Cha Mang) which appear to be used most by people from Nam Dong. However it should be noted that the thesis does not consider use by Nam Dong people of protected areas outside their own district and data presented show heavy use of protected areas in A Luoi and Tay Giang. The study also provides useful information on local people’s perceptions on the trends in forest product since 1990. All are considered to have declined except honey with timber, wild meat and fish, in particular now hard to find. Information on increases in prices is also given. The thesis also presents a table of the percentage of households using each forest product, and a seasonal calendar for the main forest products. NB: The author and Luong Van Duc worked as a team in the field. Further, comparable data on spatial distribution of forest products from other villages around the landscape was later collected by Nguyen Tien Hoang, a lecturer from the Hue University of Science, contracted by the Darwin project.
