MINISTRY OF EDUCATION AND TRAINING VIETNAM ACADEMY OF SCIENCE AND TECHNOLOGY INDTITUTE OF ECOLOGY AND BIOLOGY RESOURCES NGUYEN QUOC DUNG STUDY ON SCIENTIFIC BASIS FOR CONSERVATION AND SUSTAINABLE USE OF SEVERAL IMPORTANT RATTAN SPECIES OF THE GENERA OF CALAMUS L. AND DAEMONOROPS BLUME IN CENTRAL VIETNAM BIOLOGY PHD THESIS Speciality: Botany Code: 62.42.01.11 Advisor: 1. Associate Prf. Dr. Ninh Khắc Bản 2. Associate Prf. Dr. Lê Xuân Cảnh Hanoi, 2013 2 PREWORD 1. Thesis necessity Rattan is the common name of the plant species have spines, mostly vines, and scale fruits in Palmae (Arecaceae) belong to Monocotyledone. In Vietnam, rattan with a relatively hight number of species with 49 species have been recorded in 6 genera (author's survey). Especially notable fauna endemism of rattan very high (nearly 50% according to research by the author and his colleagues). Most species of rattan are used people, including nearly 20 species of economic value to be exploited for commercial use. Central Vietnam is the one of areas with the largest natural forests in Vietnam. Average coverage of natural forest in the study area was about 45% of the total land area. This is most one of the rattan species composition, diversity and rich in reserves. In recent years, with the region and Central Highlands region provides main raw materials for rattan processing for export and for the reade villages in Vietnam. However, rattan resources in the region are increasingly depleted, no appropriate solutions to management, recovery and development. To contribute to the conservation and development of rattan in the central region of Vietnnam as well as prevent degradation, endangered species in natural rattan, I choose a topic: “Study on scientific basis for conservation and sustainable use of several important rattan species of the genera of Calamus L. and Daemonorops Blume in Central Vietnam” 2. The objective - Evaluate rattan species composition in the Central region - Study the biological basis of the distribution, ecology, conservation value, economic value, growth and development of rattan. - Evaluation of extraction, use, market and rattan management in the study area. - Propose solutions to conservation and sustainable development of rattan in the area of Central Vietnam. 3 3. The significance The thesis results are basic science materials of composition of rattan species in Central region, contributing to the investigation, detection, additional species composition not only for the central region and Vietnam. The research results will contribute to the rationale and science for conservation and development of rattan in Vietnam. 3. The new records in thesis - Announcement of 18 rattan new species to science in the Central region - For the first time, lists of rattan built specifically for the Central region show their distribution characteristics, and used and science values. - For the first time the rattan proposed in the conservation activities in the Central region. - Thesis proposes a complete model of rattan intensive crop under the forest canopy in Central areas. Chapter 1 RESEARCH OVERVIEW 1.1. Overview of Research Issues 1.1.1. The situation overseas study 1.1.1.1. Research on the rattan classification and distribution O. Beccari is one of the first author's research on rattan studied classification and genera of Daemonorops and Calamus. Uhl and Dransfield (1987) is the author synthetic rattan on the globe and around the world have identified about 600 species of rattan in 13 genera. John Dransfield published the rattan in the Malay Peninsula (1979), Sabah (1984) Sarawak (1992), Brunei Darussalam (1997), "Plant Resources of Southeast Asia - Episode 6: The rattan" (1994); "Genera Palmarum the Evolution and 4 classification of Palms", in that Calamoideae described and identified in 619 species, separate group of Calameae in 565 species. Andrew J. Henderson has described 160 rattan species in South Asia, including 134 species of Calamus, 22 species of Daemonorops, 7 species in Korthalsia, 1 species of Myrialepis, 5 species of Plectocomia and 2 species of Plectocomiopsis. Evans and colleagues, discovered in 2000 and described four new rattan species of the genus Calamus in Laos and Thailand, book publishing field guides of _ (2001), which describe, define distribution 31 rattan species of _ the rattan in Lao PDR. K. Hourt Eang published a field guide on the rattan (2008), which describes and identifies the distribution of 18 rattan species in Cambodia. 1.1.1.2. Rattan physiology, ecology and development Xu Huang et al (2000) studied rattan morphological characteristics in China. Manokaran, N. (1985) studied ecological factors affecting the recovery and growth of rattan in several provinces of China for some species of C. Egregius, C. simplicifolius and C. Nambariensis Janmahasatien (2005) and Rao et al. (1998) studied influence of soil conditions on the growth of the rattan. Soil conditions, vegetation, microclimate, seed maturation, the formation and development stages of the trunk, etc are Manokaran N. (1985) study. Ecological adaptability of natural rattan species has been mentioned by Dransfiel (1979, 1984). A. B. Lapis et al (2005) studied of preserved fruit in Indonesia. Study in India about preserving seeds (JKRawat, DCKhanduri, 2001). Yin (2000) studied storage methods and determine the rate of seed germination. Effects of mineral nutrition and the effects of fertilizer on the growth by Qingdu Chen (2000) studied two rattan species seedlings of C. tetradactylus and D. magraritae in China. 5 1.1.1.3. Rattan conservation and use From 1981 Dansfield have evaluated the ecological problems of the rattan in Asia-related trade and conservation. FAO is one of the powerful organization concerned with the preservation and development of rattan. In particular, most clearly expressed on the use and conservation the rattan in Report No 14 on non-timber forest products. This paper also reports the rattan from Thailand, Indonesia, Philippines, NBAR is bamboo and rattan network in the world, is also very interested in conservation issues. In INBAR Working Paper No. 7 also mentioned the conservation status and rattan resources in China (Xuhuangcan et al, 1996). Report No. 11 of INBAR mentioned problems rattan selection priority for conservation and development (Rao et al, 1998) WWF (World Wide Fund for Nature) in addition to the common interest in preserving biodiversity, also interested in the programs of sustainable management of natural resources, of which there are many research activities on rattan. Analysis by Wang Kanglin (2004) refers to the variety of rattan resources in China, given the traditional experience of regeneration and protection of the cloud forest region in Xishuangbana Mengsong community. 1.1.2. Study the situation in Vietnam 1.1.2.1. Species composition and distribution The first time the rattan published in the book "Flora of Indochina". Pham Hoang Ho (1993 and 2000) have identified 30 rattan species of the rattan 6 genera. Vu Van Dung and Le Huy Cuong (1996) suggested that the rattan in Vietnam has 6 genera, 30 rattan species and 1 variatae. Tran Thi Phuong Anh is one of the authors deeply research on the classification system the rattan in the research process classification system they Cau in Vietnam. Andrew Henderson and colleagues from 2008 to today announced 20 new rattan species for science. Regarding distribution, Vu Van Dung and Le Huy Cuong 6 (1996), Nguyen Minh Thanh studied distribution by elevation, the rattan space distribution. 1.2.1.2. Study on ecological characteristics and cultivation Vu Van Dung, Le Huy Cuong (1996) studied the ecology of seedlings, and ecology of the rattan under the forest canopy. Pham Van Dien (2005) provide ecological characteristics of the stages of development of the rattan. Vu Van Dung and Le Huy Cuong (1996) technical guidance rattan species planted for 2 species of C. tetradactylus and C. platyacanthus. Forest Science Institute of Vietnam (2000) have studied the project for 5 high value rattans in Vietnam. 1.1.2.3. Rattan conservation and use The only document referring to preserve the rattan as the Vietnam Red Data Book Red Book of Vietnam (Flora 1996) and the Vietnam Red Data Book (2007) only mention the status of two rattan species of Calamus platyacanthus (VU - Vulnerable) and Calamus poilanei (EN - endangered). Regarding the use of the rattan in Vietnam Nguyen Quoc Dung (2006) evaluated the use, production, market. Ninh Khac Ban et al (2005) analyzed the current state of deep mining, use, rattan market in Bach Ma. Relatively complete documentation of the technical measures of conservation and development by the authors the rattan Pham Van Dien, Nguyen Quoc Dung et al (2011). 1.2.

Chapter 3 RESULTS AND FINDINGS 3.1. Status of the rattan resources in the study area 3.2.1. Diverse of the rattan species composition in the study area 3.1.1.1. Species diversity So far Vietnam has recorded for 49 rattan species in 6 genera. Central Vietnam found 5 genera, accounting for 83% of genera in the country, and 41 rattan species, accounting for 84% of the total number of rattan species in the country. This demonstrates that central area with a rattan species diversity in Vietnam. Therefore, the interest in the rattan conservation and development in central areas is essential. Among of the 41 rattan species identified in Central up to 22 endemic species to Vietnam. In that species distributions are very narrow, usually only found in geographic scope than 4 adjacent provinces. 9 3.1.1.2. The new rattan species described to science The surveys of the rattan in nationwide, we have discovered and described 20 new rattan species to science. Among them, there are 18 species in Central region of our country. This also proves, the central focus area distribution of rattan species in Vietnam.
