Research and conservation of plant species for the nation arboretum, collection and securing of the plant species for both public and private arboreta and education for the arboreta which is affiliated to the university are overall management goal of the arboreta in Korea. Most of the arboreta in Korea run the programs and events for guide and interpretation of forest, but the programs and events are not well specified by the arboreta. Regarding the reasonable level of entrance fee should be discussed further as the lack of information and understanding. But the specified entrance fee between public and private arboreta should be considered. An eighty three percent of arboreta in Korea has been properly managed the species information. The reasonable management should be considered in case of unusual management of collected plant genetic resources. Although the overall impending difficulties for the management of arboreta in Korea is the lack of trained or qualified staffs, securing tasks independently for the public arboreta and relatively low salary for the private arboreta are main difficulties. Most of the difficulties are derived from the lack of its mission of the arboreta. The management of arboreta by the mission statement is one of the core targets including the characters such as climate or region should be considered. The securing qualified or trained staffs should be considered in the development of arboreta in Korea including the modification of relevant regulations or law.

In this study, the population and community structure of Berchemia berchemiaefolia stands located at Mt. Naeyon (Gyeongbuk, Korea) were quantified, and multivariate analysis was done to determine the correlations between vegetation group types and environmental factors and to have reference data for the conservation and restoration of this species. In total, there were 164 B. berchemiaefolia trees in Mt. Naeyon. The average DBH of the trees was 24.5 cm, forming a normal distribution. It rarely appeared in an understory vegetation height of 3 m. About37.1% of the trees were branched. B. berchemiaefolia stands were classified into two groups: B. berchemiaefolia-Quercus serrata community and B. berchemiaefolia-Carpinus laxiflora community. Canopy gap, organic matter, exchangeable Ca, and cation exchange capacity were the major site characteristics affecting the distribution pattern of the stands. Currently, B. berchemiaefolia trees dominate in Mt. Naeyon, but depending on different habitat positions, the species was in a natural successional stage to C. laxiflora or C. cordata, which is a shade-tolerant species.

최근 기후위기 등으로 인해 생물다양성 감소 우려가 높아지고 있으며, 식물유전자원 보존의 강화를 위해 수많은 국제협약이 체결되고 있다. 자국의 생물다양성을 보호하고, 전 세계의 기후위기 취약식물의 보존을 위해 대한민국 산림청은 세계 최초로 지하터널형 야생식물종자 영구저장시설인 '시드볼트(Seed Vault)'를 경상북도 봉화에 설립하였다. 시드볼트는 안전한 종자의 저장을 위해 온도 -20℃, 습도 RH 40% 이하를 유지하며, 환경 변화를 최소화하기 위해 매일 시설 점검을 진행하고 있다. 시드볼트의 미션은 '기후위기 대응 생물다양성 확보'이며, 전 세계 종자저장의 선도기관으로 2022년 12월 기준으로 5,424종 192,625점을 확보하였으며, 2030년까지 1만 종 30만 점을 목표로 하고 있다. 전 세계 식물 종의 보호를 위해 국제기구와 협력하고 있으나, 해외 종자의 저장이 더욱 강화되어야 하며, 향후 시드볼트 종자저장 네트워크 구축에 참고하기 위한 해외 사례를 조사하였다. 아시아에서는 중국이 다량의 식물종을 수집하고 있으나, 해당 자료에 대한 공개는 이루어지지 않고 있으며, 일본은 농업식량 식물자원 중심으로 종자를 보존하고 있으며, 태국, 대만, 싱가포르 및 몽골 및 중앙아시아 국가의 종자수집과 보존은 근래 확대되는 추세이다. FAO의 Plant Genetic Resources for Food And Agriculture 관련 수집 자료에 따르면, 아시아지역 25개 국가에서 984,019점의 식물유전자원을 보고하였다. 본 연구를 바탕으로 아시아지역의 종자보존 네트워크를 구축하여 해외 종자의 안전한 저장을 통해 아시아 야생식물자원 다양성 보전 가치를 통합하는 시설로 성장하고자 한다.

This study intends to analyze the relationships between images of arboreta or botanical gardens and the policy supports related to carrying capacity. For this purpose, a questionnaire survey was distributed to 723 public sites nationwide. The results consisting of an exploratory factor analysis, a confirmatory factor analysis, a correlation analysis, and a structural equation method showed that the images of the arboretum or botanical gardens contained 3 factors: cognitive, affective and shape factors. The cognitive factors greatly affected the policy support related to carrying capacity. The policymakers of the arboretum or botanical gardens can consider cognitive elements of images as important aspects in the planning and management factors to improve the support of visitors related to the policies of carrying capacity for sustainable use.

Amid the recent intensification of climate change, the decline of subalpine coniferous species is evident. Accordingly, the Korea Forest Service is conducting research to establish conservation measures, identify the causes of the decline of subalpine coniferous species, and establish conservation strategies for seven species of conifers in the alpine region. This study used an economic value evaluation method to present objective data to inform the need for and value of conservation of endangered coniferous species through the recognition of endangered coniferous species and evaluation of conservation value among coniferous species conservation strategies in endangered alpine areas. A contingent valuation method was applied. As a result, the estimated conservation value per household of endangered alpine coniferous species was 49,181 won.

The forest vegetation of the Korean Peninsula is dominated by deciduous Fagaceae forests. The study aimed to comparethe correlation between species composition and environmental factors in Namsan, Odaesan, and Ulleungdo. A vegetation survey of 75 sites was conducted from May to August 2018. Seven vegetation types were classified. The inland representative vegetation was classified as a Quercus mongolica community, and the island representative vegetation was classified as a Fagus multinervis community. The Quercus mongolica community was subdivided into the Aria alnifolia group, representative of cities, and the Tilia amurensis group, representative of mountainous regions. Analysis of important values and indicator species to examine the succession trends according to regional types showed that urban and island forestswere maintained as Fagaceae communities, and that mountainous region foreststransitioned to broadleaf species, such as Tilia amurensis and Carpinus cordata. A CCA analysis of vegetation type and site environmental factors showed that altitude had the biggest effect on species composition at the same latitude. The study results should contribute to a better understanding of the Korean Peninsula forest ecosystem characteristics and provide basic data for establishing a systematic conservation and restoration plan.

This study was conducted to investigated woody species community classification and understory vegetation characteristics of Abies nephrolepis forest in Mt. Gyebang and Mt. Odae designated as Protected Area for Forest Genetic Resource Conservation and National Park. Vascular plants were surveyed as following; 55 family, 148 species, 3 sub species, 14 variety, 2 form 167 taxa. As an analysis of the species estimator of Jackknife 1, 29 survey plots could be representative of vegetation in study site. Results of the woody species, 3 communities were divided by cluster analysis(A=Abies nephrolepis-Tilia amurensis, B=Betula ermanii-Abies nephrolepis, C=Quercus mongolica-Abies nephrolepis). Using MRPP-test, there were significant differences between the communities indicating analysis of the appropriate group classification(p<0.01). The basal area and altitude were analyzed by negative relationship for NMS ordination. By analyzing plexus diagram of woody species, Acer pseudosieboldianum is strong associated with Quercus mongolica and Rhododendron schlippenbachii. Magnolia sieboldii is strong associated with Acer pictum subsp. mono etc.

This study measured the ecological niche overlap between two deciduous oak species(Quercus acutissmia and Q. dentata) according to the change in growth responses after treating with the moisture and nutrient contents of the soil at four gradients, and interpreted the degree of competition between the two oak species by ordination method. In the moisture environment gradient, the ecological niche overlap of the two species was high in the photosynthesis-related leaf organs and low in plant architecture such as shoot length. In addition, in case of competition between two oaks, Q. dentata was remarkably dominant in soil moisture gradient, but Q. acutissimia slightly was slightly advantageous over Q. dentata in the soil nutrient gradient. These results show that even in a similar taxonomical group growing in a similar habitat, the response to the organ system of the plant varies depending on the type of environment factor, resulting in different competitive differences among plants.
