Microscopic structures of epidermis and palynology and isozyme analysis were examined to find out the intergeneric and interspecific relationships and consequently to confirm the position of Hanabusaya aiatica as an endemic genus among 4 genera and 9 species belonging to the Hanabusaya asiatica, Korean endemic, and its allied groups. In the examination of microscopic structures of epidermis, cell patterns of perianth and ultrastructure of seed coat were found to be useful characters for the identification of the 4 genera and 9 species. Palynological characters such as microscopic structure and overall morphology of pollen grains were, however, not enough to distinguish them because of the great variabilities in these traits. Isozyme analysis showed that H. asiatica was very closly related to Campanula punctata and C. takesimana, though there were variations among populations and collected areas in some classified groups, depending on classified groups. Based on these results, the position of H. asiatica as an endemic genus was well confirmed.

Phylogenetic studies were conducted to evaluate the taxonomic relationships among 27 taxa, including 2 outgroups of Korean Campanulaceae, using PCR-RFLP analysis and ITS sequences. In the PCR-RFLP analysis, 15 restriction endonucleases produced 244 restriction sites and size variations from the chloroplast DNA, and 59 restriction sites (24%) showed polymorphism. The length of the ITS regions ranged from 588 bp to 797 bp. The sequence divergence including the outgroups is 0-39.36%. Phylogenetic analyses based on PCR-RFLP and ITS data suggest that Campanulaceae is monophyletic; Codonopsis and Platycodon forms an independent clade; the Peracarpa and Asyneuma clade is a sister to the Adenophora-Hanabusaya clade; Campanula is monophyletic; and Wahlenbergia basally branches within the ITS tree, whereas they are placed between Campanula and the Codonopsis-Platycodon clade in the PCR-RFLP tree; Hanabusaya is placed within the Adenophora clade; and Adenophora is paraphyletic and shows discordance to the infrageneric classifications based on morphological data. The present results show two data sets, largely congruent at the generic level, but their phylogenetic positions, in particular the Wahlenbergia and Hanabusaya and the infrageneric classifications in Adenophora, show some incongruence.

Phylogenetic studies were conducted to evaluate the taxonomic relationships among 28 taxa, including 2 outgroups of Korean Campanulaceae, using atpB, atpB-rbcL, atpF-H, matK, rbcL, rpl16, rpoC1 and trnL-F regions sequences in chloroplast DNA. The combined analyses of eight chloroplast DNA regions suggest that Codonopsis and Platycodon basally branches within the phylogenetic tree; Wahlenbergia distinguished an independent clade; Campanula forms a clade; Peracarpa and Asyneuma clade is a sister to the Adenophora-Hanabusaya clade; Hanabusaya is placed within the section Remotiflorae of Adenophora; Adenophora form a clade. Our present results support the generic level, although discordance remained at the infrageneric groups such as section and series based on morphological characteristics in the genus Adenophora.

Comparative studies on external morphology and anatomical characters were conducted understand the interspecific relationships and possibly to identify the position of Hanabusaya asiatica as an endemic genus among 4 genera and 9 species in H. asiatica and its allied groups. Such morphological characteristics as root shape, leaf size, presence or absence of wings in petiole, corolla and calyx shape, and inflorescence and stigma shape were useful qualitative characters. The morphology of stem, peduncle, calyx lobe, leaf, petiole, and ovary were also good characters to be included in this identification study. In the anatomical observations in these organs, projecting degree of epidermis and number of projecting area rather than cross-sectioned internal structures were found to be valuable index for the classification among species. External morphology and anatomical characters support the position of H. asiatica as an endemic genus very well. Known as the most important external characters to taxonomists(Fedorov, 1957: Nakai, 1952: Hong, 1983), leaf arrangement, inflorescence, and corolla shape were also preven to be very useful characters to identify the genera and species in the H. asiatica and its allied groups.

The flora of vascular plants investigated in Mt. Hyangro-Bong was 450 taxa belonging to 86 families, 254 genera, 393 species, 2 subspecies, 51 varieties, 4 formae. Among the investigated vascular plants, Korean endemic plants (Carex okamotoi, Salix koriyanagi, Clematis chisanensis, Aconitum pseudo-laeve var. erectum, Viola diamantiaca, Sanguisorba hakusanensis, Vicia venosissima, Patrinia saniculaefolia, Hanabusaya asiatica, H. asiatica for. alba etc.) were 23 taxa; rare and endangered plants(Disporum ovale, Lilium distichum, Trillium kamtschaticum, Gastrodia elata. Clematis chisanensis, Rodgersia podophylla, Rosa marretii, Viola diamantiaca, Syringa wolfii, Hanabusaya asiatica etc.) were 17 taxa; naturalized plants(Dactylis glomerata. Poa pratensis, Rumex acetosella, Gypsophila oldhamiana, Lepidium apetalum, Oenothera odorata, Aster pilosus, Carduus crispus, Erigeron annuus, Taraxacum officinale etc.) were 14 taxa.

The conservation status of an endemic perennial herb, Hanabusaya asiatica (Nakai) Nakai (Campanulaceae) was determined by applying the IUCN risk assessment criteria from our field study and available specimen data. Also, the GIS technology was used to develop a species distribution map to calculate the extent of occurrence (EOO) and area of occupancy (AOO) for the taxon. After two years of continuous field studies, 269 mature individuals were found in four localities in 2011, while 216 mature individuals were confirmed in three localities in 2012. Based on the following data, such as EOO (2,742 $km^2$), AOO (76 $km^2$) and estimated population size of mature individuals, the taxon, which is known as 20 localities in Korean peninsula, is evaluated as the category of Endangered (EN). A major difficulty in application of IUCN criteria to Korean rare plants were the lack of essential biological information and understanding the correct knowledge of the IUCN criteria in previous Korean studies. Sound conclusions regarding the conservation status of individual species require more intensive population studies, observations, and applying IUCN assessment procedures correctly.

DMZ 및 접경지역은 지난 60여 년간 인간의 간섭을 받지 않아 세계적으로 우수한 생태계의 보고이며, 백두대간, 도서연안과 함께 한반도 3대 핵심생태축의 하나로서 한반도생태계보전을 위한 가장 중요한 지역이다. 이러한 DMZ 및 접경지역에 대하여 국내적 중요성 인식 제고뿐만 아니라 국제적으로도 중요생물다양성지역(KBAs)으로서의 가치인식을 위해 IUCN에서 제시하는 평가기준을 검토하고 이의 기준을 적용하여 DMZ의 생물다양성에 대한 국제적 가치정도 판단 및 중요생물다양성지역(KBAs)으로서의 보전방안을 수립하고자 한다. 첫째, DMZ 일대를 대상으로 서식하는 자생식물의 분포지역을 파악하여 DMZ 및 접경지역의 식물상은 18과 139속 367종 1아종 44변종 10품종 422분류군으로, 총 138과 613속 1,517종 8아종 217변종 58품종으로 총 1,800분류군으로 확인되었다. 본 연구대상지의 동부지역에서 가장 많은 1,482분류군, 중부지역은 1,225분류군, 서부지역은 1,080분류군으로 가장 적은수의 식물이 확인되었다. 둘째, DMZ 및 접경지역을 대상으로 객관적이고 정량적인 방법을 통한 DMZ 및 접경지역의 중요생물다양성지역(KBAs) 지정기준을 적용하여 개느삼, 금강초롱, 모데미풀 3종을 중요생물다양성지역(KBAs) 후보종으로 선정하였다. 후보종별로 분포예측 결과 전체 면적 $5,270.5km^2$ 중요생물다양성지역(KBAs) 지정을 제안하였다. 셋째, 지정기준을 통하여 선정된 DMZ 및 접경지역에 서식하는 주요 식물에 대한 국제적 가치를 판단하여 우리나라 상황에 맞는 중요생물다양성지역(KBAs)을 적용함으로써 효과적인 관리방안으로 투명하고 체계화된 국제적 기준으로 해당 지역 내의 생물종 다양성을 지속가능하게 보호하기 위한 구체적인 방향 설정 및 관리를 위한 노력이 이루어질 수 있도록 유도 할 수 있다. 수집된 자료를 통하여 중요생물다양성지역(KBAs)에 적합한 종을 중심으로 보호구역을 지정하고 국내적으로 중요한 지역적 멸종위기종에 대한 적용을 추가적으로 진행하여 식물다양성이 중요한 지역의 보호를 위한 우선순위 및 구체적 접근계획을 수립할 수 있을 것으로 판단된다. 국가적인 차원에서 DMZ 및 접경지역의 지속적인 조사를 통하여 중요생물다양성지역(KBAs)기준 적용에 필요한 기초자료를 충분히 수집하고 국내 환경에 부합하는 중요생물다양성지역(KBAs)기준 적용을 통하여 꾸준히 재평가하여 후속연구의 발판을 마련하여야 한다.
