Therein, Magnolia quangninhensis Q.N Vu is the new species for the Science Based on morphology and the characteristic of each species, I was established Classification Key to Genera and species of species in family Magnoliaceae This study was defined the distribution; main forest types which species are located; evaluated the situation of naturally species at study site And also provided some recommendations for conservation, development the species of family Magnoliaceae from Yen Tu National forest, Quang Ninh province Keys: Magnoliaceae, Michelia, Magnolia, Manglietia, Yen Tu National Forest, , Classification Key I INTRODUCTION The variety of plant have long been known by more than 250 000 vascular plant species, the abundance and richness of plant have promoted and enriched the life on Earth from ancient to now With a mission protect this abundance of plant, the national forest was established and conserved by the regulations of local government in each country In Germany, there are 14 natural areas known as national parks With 9134.31 square kilometers, the German national parks account for about 2.6% of the country In the US, there are 58 national parks formally, many of which were over 100 years old Yellowstone National Park in Wyoming, Montana and Idaho was founded in 1872 as the first national park in the world Austria, there are national parks with a total area of 2,356 square kilometers, accounting for about 2.8% the area of this country In Vietnam, the good news in June 8/2015, there are 31 National Parks with a total area of national parks around 10350.74 km² (620.10 km² of which is sea level), accounting approximately 2.93% of the land territory (Follow "Information about existing and recommended which areas protected in Vietnam, Vietnam Bird Life") One of them is the Yen Tu National Forest, with a total natural area is 2783.0 hectares, located in Thuong Yen Cong Commune, Dong Phuong Commune, Uong Bi city, Quang Ninh province, far from Ha Long city 40 km, 150 km from Hanoi capital Yen Tu National Forest has the ecosystems very unique, the biological diversity is richness with alot of genetic resources of plant and rare animal and standard samples of forest ecosystems of the Northeast-Vietnam This place also is one of the scenic spots, tourist attractions, and traditional festivals of the whole country; simultaneously is a Vietnam Buddhist Center To reevaluate the existing plant resources of this region, as the basis for building Relics August 2010, Sub Institute Forest Inventory and Planning of North West in cooperation with Department of forest plants, Forestry University open the enumerate addition survey to evaluate the plant resources Based on the survey results, according to the standard classification of vegetation cover by Dr Thai Van Trung, Yen Tu National has two main forest types: Forest evergreen tropical rainy season, this forest type distribution at elevations below 700 m; Dense evergreen forest subtropical, low mountain distributed at 700 m - 1068 m With forest status and 11 forest types of major plants not including those of IIA and IIB forest status The plant species typical of this region are: Erythrophleum fordii, Sindora tonkinensis, Vatica odorata, Dacrydium pierrei, Phyllostachys spp., Magnolia spp., Piper betle, Aegiceras corniculatum terrestrial This is also the plant species specific to region of Quang Ninh and the Northeast Vietnam The family Magnoliaceae is one of the important groups in flowering plants not only in studies of plant evolution and biogeography but also in their values Most species of this family are woody trees, and some are shrubs characterized by an androecium of numerous spirally arranged stamens, a gynoecium with many simple carpels spirally arranged on an elongated axis and separated tepals Most species of Magnoliaceae are used for wood and landscape, and some are used for medicine The family consists of 12 genera and 230 species with a peculiar distribution with an eastern center comprising the Indo-Malayan region, S China, Japan and Australia to the south and western center in N E United States and southwards to Brazil and W Indies It is absent in Africa and Europe But fossil remains were discovered in Tertiary deposits in the Artie Circle, Greenland, Europe and Central N America In Vietnam, at least ca 50 species of Magnoliaceae was currently recorded (Vu, Q.N., 2014), but there are few studies focussed on the limited area such as national park or nature reserve to recognize the species composition and also to propose the solutions for conservation and development of species During the field trip course of BZ 224 – Plant Identification and several times traveling, I realized that Yen Tu, a National Forest located in Quang Ninh Province and not far from my home town, has special ecosystem and high biological diversity with rare plant and animal genetic resources and standard samples of forest ecosystems of the NortheastVietnam It also is one of the scenic spots, tourist attractions, traditional festivals of the country and the world; and is a Vietnam Buddhist Centre In those times, I also found that there are many trees with big white flower, fragrant smell and beautiful shape My teachers showed that they are species of the family Magnoliaceae and I loved them from those times By literature review, I know that there are many studies and publications on Magnoliaceae on the world with some aspects, such as: taxonomy, phylogeny, anatomy, ontogeny, karyology, molecule, etc In Vietnam, there are some publications mentioned mainly on taxonomy as informing the newly records of some taxon of the family Some other also mentioned on biological characteristics of specific species, such as: Vu et al (2013) in the study “Some biological and ecological characteristics of Manglietia sapaensis N.H.Xia & Q.N Vu at the Hoang Lien National Park, Lao Cai Province” showed that Manglietia sapaensis is narrowly distributed naturally from 2,017-2,581m alt (Núi Xẻ - Fanxipan path), in which topography is dismembered strongly, containing numerous high peaks with high slopes Total 37 species are occurring in the high tree composition, from which 18 species are listed in plant composition Manglietia sapaensis only participates the plant composition from 2,234-2,400m alt and it plays an important role in these plant communities Of the total accompany species, request species are Myrsine semiserrata, Betula alnoides, Castanopsis sp., Cornus hongkongensis, Michelia aeana and Litsea cubeba Average density of Manglietia sapaensis is 150-250 trees/ha on 2,300 - 2,400m alt It is able to be regenerated by both seeds and shoots, but the first is dominant In the regeneration layer, average density is from 3,68010,000 individuals/ha and that of Manglietia sapaensis is from 160-400 individuals/ha Result indicated that Manglietia sapaensis is best regenerated from 2,300 to 2,400m alt and this can be applied on natural regeneration methods to reforestation of this species in Hoang Lien National Park Vu, Q.N., H.H Nguyen & P.T Nguyen (2014) in “Some biological characteristics of Alcimandra cathcartii Hook.f & Thomson at the Hoang Lien National Park, Lao Cai Province” showed that A cathcartii is distributed from alttitude of 2.000 - 2.600 m, along the path from Tram Ton to Fanxipan peak of the Hoang Lien National Park In forest community, A cathcartii is dominant and plays an important role in plant composition It often occurs with some relative species like Elaeocarpus griffithii, Castanopsis phansipanensis, Rhododendron sinofalconeri, Machilus odoratissima and Rhodoleia championii The density of A cathcartii in the forest is quite high, ca 200 - 250 trees/ha A cathcartii can regenerate from both seeds and stump shoots, but usually in seeds and rather good, ca 560 - 2.720 saplings/ha Truong Van Phu (2014), “Some Characteristics Of The Family Magnoliaceae From Bat Dai Son Nature Reserve, Quan Ba District, Ha Giang Province”, informed that there are species belonging to genera of the Magnoliaceae found in Bat Dai Son Nature Reserve, Quan Ba District, Ha Giang province, and those are: Manglietia phuthoensis Dandy; Manglieatia longirostrata (D.X Li & R.Z Zhou) Q.N Vu; Manglietia megaphylla (Hu & W.C Cheng); Michelia balansae Dandy; Michelia fulva (Chang et B.L Chen), Q.N Vu; Michelia citrata Q.N Vu & N.H Xia; Michelia foveolata Merrill ex Dandy Therein, species are new recorded for Flora of Vietnam, those are: Manglieatia longirostrata (D.X Li & R.Z Zhou) Q.N Vu, Manglietia megaphylla Hu & W.C Cheng, Michelia citrata Q N Vu & N H Xia Specimens for all species were collected by him from the field survey In Yen Tu National Park, I know that there are some studies on plants or flora there, but no study was focussed on the family Magnoliaceae Hence, I choose the subject "Some Biological Characteristics of the Family Magnoliaceae from Yen Tu National Forest, Quang Ninh Province" to improve understanding and suggesting the course of forest conservation and sustainable development of this family in the research area - This research study just stop at species composition, conservation status and silvicultural characteristics of species in family Magnoliacae in study description that are not going deeper into the technical for breeding and planting and developing of this species 5.3 Recommendation Management board of Yen Tu historical relics and Yen Tu National Forest and other relevant authorities need to promote the conservation benefits for significant species and encourage protection the family of Magnoliaceae and other populations by the local community at Yen Tu National Forest Quang Ninh Department of Science and Technology and management board of Yen Tu historical relics and Yen Tu National Forest need to collaborate with local communities and other scientific institutions to design and plan a project to further assess conservation status and promote conservation benefits for protecting species the Family Magnoliaceae have high conservation value The aim of such a project would be to protect genetic resources in Yen Tu National Forest An understanding of the social-economic value of many of the discovered species of Magnoliaceae within local communities is limited Therefore, Some suggested on-ground conservation directly involving the participation of local communities include establishing seed banks, collecting seed, establishing nurseries to propagate important economic species and establishing tree protection programs 41 VI REFERENCES Documents Vu Quang Nam (2014), “Taxonomic Key: Case Study of Magnoliaceae from Vietnam” Science and Technology Journal of Agriculture & Rural
