Bidoup Nui Ba National Park located in Lam Dong province was established in 2004 and named after the highest peaks of the Langbiang plateau: Bidoup (2,287m) and Nui Ba (2,167m) Over 1,933 recorded species of vascular plants including 96 endemics and 62 rare species are listed in the IUCN Red list 2009 The park is a residence of over 15 out of 33 conifer species in Vietnam including many endemic and rare species, namely Taxus wallichiana, Pinus dalatensis, etc The Gymnosperms in Bidoup - Nui Ba National Park and the surrounding area has been heavily exploited in recent years, so conservation is an essential issue Due to this practical problem, I decide to conduct the thesis titled: “Conservation of Gymnosperms in Bidoup - Nui Ba National Park, Lam Dong province”, with the aims of providing more information on some of the biological characteristics, distribution conditions and solutions that would be necessary for the identification, conservation and development of Gymnosperms in Vietnam and over the world 1.1 The researches of Gymnosperms in the world There are about 250,000 species of high plants while Gymnosperms accounts for only 600 species across the world Robert Brown (1773 - 1858) was the first to recognize the difference between Gymnosperms and Angiosperms Angiosperms have seeds that are enclosed within an ovary (usually a fruit), while Gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves Holmes (1986) in her book entitled “Outline of Plant Classification” divided Gymnosperms into three classes (Cycadopsida, Gnetopsida, and Coniferopsida); however, described some fossils ancestors in a separate class Progymnospermopsida Kramer and Green (see Kubizki, 1990) have classified the Division Gymnosperms into two Subdivisions (Cycadophytina and Coniferophyna) In addition, The Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950s onwards He divided the Gymnosperms into six classes and subclasses, 10 families His classification system demonstrates the general application of materials in the fields of morphology, anatomy, biochemistry, paleontology and plant cellular The evolution of plants has been used extensively in the world Although since the Cretaceous Period (about 145 million to 66 million years ago) Gymnosperms have been gradually displaced by the more recently evolved Angiosperms, they are still successful in many parts of the world and occupy large areas of Earth’s surface Conifer forests, for example, cover vast regions of northern temperate lands, and Gymnosperms frequently grow in more northerly latitudes than angiosperms There are currently over 200 species in the field that are considered to be endangered throughout the world Common threats include overexploitation of wood or other products, deforestation for cattle grazing, cultivation and human habitation, and increased frequency of forest fires 1.2 The researches of Gymnosperms in Vietnam In Vietnam, there are about 29 species of Gymnosperms, accounting for 5% of the total Gymnosperms species in the world Although less than 5%, they make up 27% of the genus and in families known in Vietnam There have been several types of research on Gymnosperms in Vietnam such as: Flora Generale de L'Indo-Chine (Vietnam + Laos + Cambodia) was designed by H Lecomte (1907-1952) French authors had collected samples and named, then set a description of vascular plants throughout the territory, where Gymnosperms has been clearly introduced and described Based on the Indochinese flora, recently Flora of Cambodia, Laos, and Vietnam has been published by Aubréville (1960-1997) Besides various other authors has also published a number of vascular plants In which species of Gymnosperms have been introduced In addition, Vietnam Herb of Pham Hoang Bo (1991-1993) published in Canada has been reprinted with supplementation in Vietnam for years (1999-2000) which is completed and easy to use contributing significantly to the Gymnosperms science Vietnam conifers of Nguyen Hoang Nghia (2004) and Conservation status of Nguyen Tien Hiep et al (2005) These documents described and assessed the status and conservation of some species belonging to Gymnosperms in Vietnam Recent findings have added some valuable species to the flora of Vietnam such as Pinus kwangtungensis (Phan Ke Loc, 1984), Amentotaxus hatuyenensis (Nguyen Tien Hiep & Vidal, 1996), Pseudotsuga sinensis and Tsuga chinensis (Nguyen Tien Hiep et al., 2000), Keteleeria davidiana (Phan Ke Loc et al., 2002), Calocedrus rupestris (Averyanov et al., 2004) and most recently Pinus cernua (Pinus cernua) (Phan Ke Loc et al., 2014) In Vietnam, almost species of Gymnosperms are threatened at the certain level Most of these species are supplied for the production of fine arts and construction products Some species are also used as flavor or in traditional medicine and modern medicine regenerates under the mother tree 100 trees/ while they often disperse and regenerate from the mother tree at a certain distance 175 trees/ha It is noticeable that the natural generation of trees under cm in DBH is more dominant than trees with DBH from to 25 cm Because seed can germination rapidly when getting the good conditions as suitable moisture under canopy but it hard to be mature and competitions is one of reasons 4.2.3.4 Evaluating challenges and opportunities of Taxus wallichiana in Bidoup-Nui Ba National Park The total area of Taxus wallichiana in Bidoup - Nui Ba National Park is small, only 120 Natural factors are negatively affecting on the survival of this species For example, the distribution areas are scattered and fragmented so the populations are difficult to contact each other Pests, competitions, rainstorms strongly impact on this species The shortage of next adjacent generations is also one of the reasons for the decline of Taxus wallichiana in the future Currently, the impact of human on Taxus wallichiana in Bidoup - Nui Ba National Park is not significant However, the pressure of illegally exploiting on Taxus wallichiana is increasing rapidly due to the pleasure of using it as interior decoration and the concept of making medicine from shell and leaves Thus, the risk of extinction for Taxus wallichiana in Bidoup - Nui Ba National Park in particular and in Lam Dong province is noticeable, unless effective technical measures to protect and develop these populations Therefore, the establishment and implementation of protection and development plans of Taxus wallichiana in Bidoup-Nui Ba National Park is really necessary On the other hand, the implementation of the conservation of Taxus wallichiana in Bidoup-Nui Ba National Park also has certain advantages Bidoup - Nui Ba National Park is the conservation unit with the natural distribution of Taxus wallichiana, so the conservation of this species is appropriate in both natural ecology and legal aspects Moreover, the national park has set a large number of tables on each individual to manage the population more closely In addition, the NP has human resources with high professional skill and experience in conservation that can satisfy the requirements in the implementation of the plans 33 4.3 Proposing some solutions to preserve and develop the Gymnosperms in Bidoup - Nui Ba National Park, Lam Dong province Based on the survey’s results of the composition of Gymnosperms and the conservation status of Taxus wallichiana in Bidoup - Nui Ba National Park in order to preserve the Gymnosperms species I suppose some approaches: 4.3.1 Technical solution Ex-situ conservation In Bidoup - Nui Ba National Park, each species has its own strength, so the authorities should have a clear and practical orientation in selecting varieties which suitable with the characteristics of the area Developing guidelines and technical procedures for Gymnosperms plantation in different ecological zones and building planting models of these species under the forest canopy in order to replicate and develop on a large scale, and help species that are still limited in nature and poorly regenerated These days, Gymnosperms species are mainly derived from natural regeneration from seeds, some from buds Therefore, it is necessary to widen nurseries having high quality for conserving and planting forests The species that has advanced techniques should be quickly transferred training; the species that has not been researched on seed improvement need to undertake research for conservation It is necessary to encourage forestry expansion to improve the technical planting skills Raising awareness from depletion to sustainable exploitation to ensure the regeneration and sustainable business It is necessary to study the impacts on Gymnosperms species in nature, propose reasonable methods, and avoid the impact on land and habitat of flora and fauna In-situ conservation For the present species of Gymnosperms and its distribution area, the NP management should intensively patrol, inspect and protect, especially Taxus wallichiana, Keteleeria evelyniana, Cephalotaxus mannii, Nageia fleuryi, and Cycas michotzii because the number of these species is very small and the distribution is limited At the same time, closely coordinating with local authorities, the local community in patrolling and demolishing timber logging camps in the forest Propagandizing the importance of conservation, strictly protected areas, prohibit exploitation and impacts on Gymnosperms growth and natural regeneration in Bidoup - Nui 34 Ba National Park Guiding local community to build village conventions on the conservation of Gymnosperms species and building letterboxes to timely prevent illegal deforestations From practical conditions, it is possible to promote natural regeneration under the mother individuals as well as to expand the distribution and regeneration capacity of the species It is necessary to have more researches about each species belong to Gymnosperms in Bidoup - Nui Ba National Park to further understand the distribution, ecological characteristics and potential regeneration of Taxus wallichiana, and other Gymnosperms species due to their limited natural numbers In addition, in order to avoid detection of loggers, new Taxus wallichiana should not be set tables GPS positioning and mapping could be used to monitor 4.3.2 Socio-economic measures Due to the demand for social-economic development, biodiversity conservation solutions supposed must be suitable for each local condition and be ensured social security and economic development in Bidoup-Nui Ba National Park Building programs to raise awareness of all inhabitants who live in core zone and buffer zone, especially local leaders, village elders by several methods so that they can join hands to conserve species in Gymnosperms and the ecosystem in general Reviewing, finalizing and supplementing existing policies such as forestland allocation, start-up capital support programs, credit investment, etc In order to reduce the dependence of the local community in the national park, the management could encourage the reforestation and protection of the forest and the locals can get benefit from forest protection in their own living areas Develop ecotourism models and improve facilities so that local residents can participate in tourism, increase income and be more aware of the protection Thus, to reduce the pressure on forests exploitation as well as to protect the forest ecosystem in Bidoup - Nui Ba National Park in a sustainable way when people get benefit from the forest 4.3.3 Solutions on mechanisms and policies Strengthening the management, detection, prevention and prohibition activities of exploiting and trading these species Raising awareness of staffs and the locals so that they understand and comply with the Forest Protection and Development Law, Biodiversity Law 35 Raising the capacity of law enforcement for the forest protection staffs, ensuring the qualification, capacity, and health to effectively implement the law and deal with violations in the fields of forest protection and management 4.3.4 Solutions on capital Planning the tourist area, introducing the potential tourism of the park, investment environment (location, business environment, land fund ) to call for nationwide and worldwide capital to invest capital for services and ecotourism Attracting capital from various sources for the development of the Gymnosperms such as the own capital of the residents, private enterprises and foreign direct investment capital Set up models of demonstrating the importance of Gymnosperms in remote areas so that they can understand the role and value of conservation As a result, the awareness and undeveloped cultivate modes of the local community in Bidoup - Nui Ba National Park can be improved 36 CHAPTER V: CONCLUSION AND RECOMMENDATION 5.1 Conclusion There are 15 species of families of Gymnosperms in the study area There are 14 species listed in the IUCN (2018), species listed in the Vietnam Red Book (2007); species listed in Decree 32/2006 / ND-CP of the Government in Bidoup - Nui Ba NP are most distributed at the height of 1,500-2,000m (10 species, accounting for 66.67%); The height of 1,000m - 1,500m (6 species, 40%) and the height of 1,000m There are species (20%) of total species of Gymnosperms in the field Provide morphological, ecological characteristics and distribution of important Gymnospermae species in the research area: Pinus krempfii Lecomte, Podocarpus neriifolius D Don, Fokienia hodginsii (Dunn) A Henry & H Thomas Keteleeria evelyniana Mast Nageia wallichiana (C Presl) Kuntze, Pinus dalatensis de Ferre, Dacrycarpus imbricatus (Blume) de Laub and Taxus wallichiana Taxus wallichiana is found in the dominant layer of forest with other species of G, Podocarpaceae, Cephalotaceae, Fabaceae, Magnoliaceae, Lauraceae, Dipterocarpaceae, and Myrtaceae Taxus wallichiana grows on many different soil types such as reddish yellow on granite, reddish brown on basalt, yellow-brown on ditties, in elevations from 1400 to 1750 m, on mountain slopes terrain, steep slopes, along streams or adjacent areas between broad leafy-coniferous forest and Pinus kesiya forest They can be concentrated as large populations such as in sub-zone 102, 130, 128 or scattered as in sub-zone 101, 125 belonging to Lat and Da Chais communes According to the survey result, there are 124 mature Taxus wallichiana, in which 100 individuals are tabulated Average height at breast (D1.3): 47.7 cm and average height (Hvn): 20,81 m The amount of regenerated trees is quite large but the number of trees is very low The average number of regenerated trees (D1.3 < 6cm) was 116 trees/ha, while the number of trees (D1.3 from 6-25 cm) recorded was only plants in two sub-zones 102 and 128 37 5.2 Recommendation It is important to have more researches on the propagation of rare species of Gymnosperms in the National Park, especially Taxus wallichiana, which is listed as an endangered species by IUCN It need to have more deep conservation studies of other rare and endangered species in the study area It is necessary to expand the survey lines, set up more research plots, collect and survey specimens on different terrain types to determine the species composition in the study area more completely accurate 38 REFERENCES Bidoup-Nui Ba National Park (http://bidoupnuiba.gov.vn) Farjon, A 2010 A Handbook of the World's Conifers Koninklijke brill, Leiden The government of Vietnam 2006 Decree NO 32/2006/ND-CP Management of endangered, precious and rare forest plants and animals Ministry of Agriculture and Rural Development, Hanoi Kubitzkii et al (1990) The families and genera of vascular plants Le Xuan Tung, Tran Van Tien, Hua Vinh Tung, Nguyen Hoang Nghia, 2009, Research on planting technique of Taxus Wallichiana Zucc in Lam Dong Nguyen Hoang Nghia (1999), Biodiversity Conservation, Forest Science Institute of Vietnam, Agricultural Publishing House, Hanoi Nguyen Quoc Dat, 2016, Study on Gymnosperms species characteristics in Bidoup Nui Ba National Park, Lam Dong province Nguyen Tien Ban (Ed) (2007), Red data book of Vietnam Vol.2 Science and Techniques Publishing House, Hanoi, Vietnam Nguyen Tien Hiep, Phan Ke Loc, Nguyen Duc Luu, Philip lan Thomas, Alios Fajon, Leonid Averyanov and Jacinto Regalado Jr, (2004), Research in the status of pinophyta species in Vietnam in 2014, Labor and Social Publishing House, Ha Noi 10 Takhtajan A.L (2009) Flowering Plants 11 The IUCN Red List of Threatened species, 2018, International Union for the Conservation of Nature and Nature Resources 12 Vuong Chi Hung, (VIMEDIMEX pharmaceutical company), Nguyen Hoang Nghia (Forest Science Institute of Vietnam) Research of some characteristics of Taxus wallichiana Zucc in Lam Dong province 13 Vuong Chi Hung, 2009, Study on the process of planting Taxus wallichiana Zucc for the production of medicinal plants 39 QUESTIONNAIRES Local people Survey and Questionnaire Name: Address: Jobs: How often you go to forest?
