  • Have installedmonitoring quadrats conducting the targeted preservation valued plants environment survey (12 spots of 10 kinds), also conducted reinvestigation on the type classification of 7 places based on the results above on the 10 targeted places.

Excavation and Preservation of Ethnobotany Resources

1) Purpose

  • Establish Korean Peninsula traditional plants database for updating and futurization on traditional (folk) knowledge on our national characteristic traditional forest plants.
  • Excavate high value added plants based on the new ideas and technology to refocus the value of the traditional (folk) plants as resource.

2) Results

  • Collected 600 cased of traditional plants utilization information of ancient “Enlarged Forest Economy (1766)” before Korean modern history (1900), and 42 localplant specialists. And established the assess system of collected information using Delphi survey technique (2005)
  • The survey of the bibliographic on traditional plants has collected traditional (folk) plants utilization information of 547 forest plants subject to the materials of ancient documents since modern history, and arranged the survey of bee plants (9%) (2006).
  • Made the DB of 668 kinds of forest plants including utilization information on 202 kinds of traditional (folk) plants of Jeju Island and part of Gangwon province. And published a book “Korean Peninsula Traditional Plants” (2007) based on 414 kinds that was used among people in 1930’s.

Exploration and Secure Domestic and Foreign Useful Plant Resources

1) Purpose

  • Secured in early stage the edible, medicinal, landscaping, perfumes, paints and foreign useful plant resources
  • Promote plants industrialization in collecting foreign useful plants and building utilization system.

2) Results

  • Domestic and foreign useful plant resources exploration plan is based on the result of the contract research“Domestic and foreign useful plant exploration and collecting plant” made in 2003.
  • Domestic useful plant resources exploration had been progressed from 2003 regional exploration, and from 2004 subjective plant exploration. Collected till 2006 primarily, the plant seed, plant sample and video data based on the Korean Peninsula plant distribution sub-region like South Sea sub-region, Jeolla-do province, Gyeongsang-do province, Chungcheong-do province. Based on the results of the exploration, Korean Peninsula Vascular Plants Distribution (I-IV) was published. Since 2004, conducted plant exploration business by project like basin specific aquatic plants and endemic plants.
  • Secured 48 kinds of specific plants like thin melandryum firmum from 2001 to 2006.
  • The target of the domestic useful plant exploration was to collect indigenous plants and useful plant resources, butas a herbarium secured business-oriented, deterioration of useful organism and seed substantiality, andit will be inevitable to change exploration plan caused to that it does not meet the target of useful plant resources exploration as the Evaluation Committee pointed out like increase delivery rate ordinary plants and naturalized plants among collected plants, duplication of collected flora and occurred problems like duplicated delivery of Arboretum tasks and results.
  • In 2007, to complement these problems we have strengthened the exploration by subject like endemic plants, traditional plants (spices, etc.), and salt-resistant plant, rare plants, and for the systematic management we have made the connection with each related subjects. As the result, we have collected 716 kinds of organisms and seed including 80 kinds of endemic plant taxon, and 200 pieces of traditional plants information and using parts.
  • Foreign useful plant resources exploration was made primarily from the Korean Peninsula and expanded to the distant area from the Korean Peninsula in the method of exploring based on the similar weather conditions with Korean Peninsula.Explore China, Japan, Russia and Mongolia in priority, then enlarged to subtropical regions like South Africa, South America, Indonesia and Vietnam. As the result of the exploration, we have collected 377 kinds from Hubei, West-North region of Yunnan, Jilin region of China, Uzbekistan region, and 277 kinds of medicinal plants, traditional plants, ferns and bulbs discoid stem from Indonesia and Vietnam region. Because of the previous investigation has been sufficiently made to the subject region, as it is pointed out that the collection should be done by subject plants considering the usage, so in 2007 we made the plan to explore and collect by subject plants in the previously explored regions.
  • In 2007, we collected 603 kinds of plant seed, organism samples and evidence samples including Rhododendron, Dendrobium, Thymus in the purpose of ornamental, horticulture, spices, ground covering plants in China, Mongolia, Vietnam, Laos, Malaysia, Nepal and United Kingdom.

Taxonomic Studies of Microlepidoptera Parasites on Forest Plants

1) Purpose

  • Establishing the systematic taxon of Microlepidopteria living in forest plants, we have created the basic data needed in systematic taxon collecting and practice research of the subject taxon, and creating data of related insects by exact host plants, we have made them to use practically in tree management and related field.

2) Results

  • Through the nationwide collecting research in 2005, we have secured the sample of Microlepidopteria and have them classified the movement, and classified the major grouping, the Tineoidea in 87 species of 6 families. Also we have made 66 kinds of host plant research, and collected the information on the kinds of Microlepidopteria doing harm to each host plant. Aside, through this overall classification research of Microlepidopteria, we have discovered for the first time, stated and reported 1 unrecorded Matsumuraeses genus, 1 new and 2 unrecorded EmmelinaMonodactyla, 1 new and 5 unrecorded Ancylis from East-Northern mountain region of China near Korea.
  • In 2006, to secure the sample of Microlepidopteria, we collected 1,900 pieces of research materials through nationwide collecting survey based on Chungcheongprovince, we recorded the data on 211 kinds of Korean and East-North Chinese region Tortricidae arranging the major subject to classification research which is Tortricidae. Through this survey, we have discovered new classifications including 2 new and 3 Chinese unrecorded Gracillarioidea, 3 kinds of Chinese unrecorded Olethreutid moth, 6 kinds of Chiese East-North unrecorded Flower Olethreutid moth. Also, aside, we have noted and reported 1 new specie among arranged 7 kinds of Korean Endotricha and 2 kinds of Vietnamese Alucitoidea.
  • In 2007, we have collected 340 kinds of samples from Gyunggi, Gyungsang-do region to secure the sample and survey the habitat of Microlepidopteria, made the general catalogue of 379 kinds of Tortricidae, and also arranged the catalogue of 103 kinds of Piralid moth, Almond moth and Silk Piralid moth. Aside we have promoted the taxon research of Gelechioidea, Nepticuloidea, Incurvarioidea to confirm various new taxon, and made the illustration of these species. And we have also confirmed 19 kinds of host plants the host plant survey.

Taxonomic Reconsideration of Gymnosperm off Korean Peninsula and neighborhood Region

1) Purpose

  • We will publish the result of the systematic taxon influencing flexible relation between taxon grouping exactly identifies 70 gymnosperm taxons.

2) Needs for Research

  • About 760 species of 70 families (Mabbery, 1990) of Gymnosperm exist in the earth are used broadly as plate, wood pulp, roadside tree, so as highly used economically.
  • In spite of economically important plant, gymnosperm reported in Korea 44 taxa 13 genus 8 families of Jung(정)(1957), 64 taxa 21 genus 7 families of Lee(이)(1985), 53 taxa 20 genus 7 families of Lee(이)(1996), 48 species 21 genus 6 families of Lee(이)(1997), 64 taxa 19 genus 8 families of Lee(이)(2006) and the national standard plants list(2007) is arranged with 73 taxa 21 genus 8 families, as shown family, genus and also taxa are differently reported following thespecialists For example Lee(이)(1983) included the cephalotaxus and torreya in taxaceae, but in Jung(정)(1957), Lee(이)(2006) and the national standard plants list(2007) included the cephalotaxus as an independent cephalotaxus and the terreya in taxaceae, arranged as the Japanese terreya. However this kind of taxonomic arrangement is not based on morphological, anatomical, cytological and chemical methods but have been arranged based on the picture book and reference books.
  • Morphological studies on Korean gymnosperm(bark: Kim(김) etc. 1992; pollen: So(소) etc. 1994; observing cuticles: Kim(김) etc. 1995) has been done by selecting the one species of each taxa, there is no studies on all kind of gymnosperm taxa.
  • Recently, there is studies on ecology(Lee(이))•Cho(조), 1993), variation of shape of leaves (Lee(이)•Kim(김), 1982) and diversity (Kim (김)•Hyun (현), 2000) of the endemic species, Korea fir(Abies koreana), characteristic analysis using mathematical analysis of Abiesnephrolepis and Abies koreana, the overlapping was pointed (Jang (장), Jeon (전), Hyun (현), 1997). Also there is a case (Jeon (전), 1988) of considering Abiesnephrolepis and Abies koreana as same species or mutation, so it is needed to observe the anatomic morphological characteristics because of the criticism of the taxanomic substance of these two species.

Infrastructure of Korean Peninsula Forest Biological Specimens

1) Purpose

  • For basic studies and base of practical use of forest biological resources of Korea, it is absolutely necessary to acquire actively the evidence sample to arrange the taxonomic-basis.
  • Through building a systematic and essential sample infrastructure, discover the new habitat and unrecorded indigenous species of particular species (endemic, rare and endangered).
  • To raise up the management function of national biological sample which is the characteristic function of the herbarium operated byKorea National Arboretum within KNA, it is performing the national administrative function of forest biological herbarium with securing samples of international level and important academic, resource values.

2) Results

  • In 2006, we have secured 32,580 pieces of samples on plants, insects, moss and plants miniature painting of forest living creatures. Particularly, we have results, as the collection of 51 groups of Korean endemic plants, 44 groups of KFS designated rare plants, 2 groups of South Korea un-recorded plants, 156 species of unpossessed timber of forest herbarium and 405 species of 4 orders, 17 species of type specimen of insects, 2 groups of unrecorded moss of Korean Peninsula, and 55 pieces of Bukhan-San moss samples. Also secured the possessing status for national and international important samples, and among them, secure 132 pieces of samples of plants and insects, 31 pieces of plant type specimen of North Korean specimen in Hungarian Natural History Museum and identified the type specimen of 13 possessing samples of forest herbarium (KH). Besides, through collecting the original report, collect about 20,000 pieces of Scientific name report on plants living in Korean Peninsula, and a part of this report is published (Study No.6 『Plants type specimen material collection III』). And have also identified in-country unidentified types. Aside, establish basis for sample securing business conducting classification following the importance of the sample and standardization by level by sample production.
  • In 2007, we secured 34,800 sample pieces of plants, insects, moss and higher fungus among forest specimen. Among these, especially, we secured 57 groups of Korean endemic plants, 60 groups of KFS designated rare plants, 5 species of DMZ bug samples, 12 species of bug type samples, and 75 pieces of North Korean moss. As a part of research and securing possessing status of in-country major samples, we secured 2 groups of plants type specimen, 142 pieces of North Korean samples in Hungarian Natural History Museum, 2,500 pieces of cicada samples, 500,000 pieces of living bees research samples, 261 pieces of bug and 17 pieces of plant samples of National plants inspection institute. To secure the sample from abroad, contract an MOU with Heilungchiang forest botanical garden and Hungarian Natural History Museum, and secured 350 pieces of plant samples of East-North region of China. Published ‘National Standard Plant list’ with 4,882 species of plant standard names, and not only securing 50 pieces of plant miniature painting but also completed research of study case to develop sample management program.

Research on the Standardization of Korean Cultivated Varieties Names

1) Purpose

  • On-going operational management of national standard list system
  • Create the standardized and systematic arrangement list of Korean cultivated species.
  • Secure photographs and samples of cultivars

2) Needs for Research

  • For the systematic management of plant resources, exact classification and breed name of the plants that are planted and managed in arboretum is needed, but in the practical botany field, the legal name transcription is not exactly marked on the name agreement, so it causes lots of confusion and the needs of the public demand is growing rapidly. In addition, the differences exist in Korean Information Spelling Unification Regulation.
  • Following the operation of the species management system introduction and national species registration regulation, accurate record of cultivation species name is a very urgent task. Currently, 600 kinds of breeds are registered in the national seed institute, but it is very confusing because it does not match with the international breed name regulation or it is not standardized.
  • Until now, in KNA, we developed Nation standard listing system, build the system of reviewing and managing of cultivating species name within, and through the review of the inspectors, we have developed the system providing standardized list, but in orderto study and analyze the list of extensive cultivation species name systematically, separate and intensive research is required.
  • In particular, these cultivation species name field research differentiate from National institute of Biological resources work, and also differentiate from rural development and general crop-can field, it is considered as an important filed, especially securing the evidence photographs and samples of the species, this can be systematic and more comprehensive plant management.
