This study is to find out the proper planting and utilization plans for climbing plants in urban community gardens. As a result, a majority of respondents claimed that it is acceptable to plant climbing plants in their plots of the community garden. In particular, those who have experiences with gardening activities responded that climbing plants could be allowed in the community gardens. There was a high tendency to use climbing plants in community gardens for aesthetic or ornamental use and for creating fences. Many respondents also claimed that the climbing plants should be planted outside or on the edge of the garden and that the plants should not cross over to other plots. Those who responded that the climbing plants should be planted outside or on the edge of the community garden wanted to use the plants for aesthetic or ornamental use. Those who wanted to use the plants for creating shades responded that the plants should be planted outside or on the edge of the garden. For proper planting of climbing plants in the community garden, it is necessary to consider the height of the vertical plant support depending to the gap between the plots in the community gardens, the shape and color of flowers, leaves, and stems for aesthetic use, and mixing of plants for the duration of the shade period. Accordingly, introduction of climbing plants can be considered to increase the diversity of plants in urban community gardens.

Background: To address the lack of evidence supporting invasion by three invasive plant species (Imperata cylindrica, Lantana camara, and Chromolaena odorata) in tropical ecosystems, we compared the ecophysiological and leaf anatomical traits of these three invasive alien species with those of species native to Sempu Island, Indonesia. Data on four plant traits were obtained from the TRY Plant Trait Database, and leaf anatomical traits were measured using transverse leaf sections. Results: Two ecophysiological traits including specific leaf area (SLA) and seed dry weight showed significant association with plant invasion in the Sempu Island Nature Reserve. Invasive species showed higher SLA and lower seed dry weight than non-invasive species. Moreover, invasive species showed superior leaf anatomical traits including sclerenchymatous tissue thickness, vascular bundle area, chlorophyll content, and bundle sheath area. Principal component analysis (PCA) showed that leaf anatomical traits strongly influenced with cumulative variances (100% in grass and 88.92% in shrubs), where I. cylindrica and C. odorata outperformed non-invasive species in these traits. Conclusions: These data suggest that the traits studied are important for plant invasiveness since ecophysiological traits influence of light capture, plant growth, and reproduction while leaf anatomical traits affect herbivory, photosynthetic assimilate transport, and photosynthetic activity.

Arctium tomentosum Mill. (Asteraceae), from Ulaanbaatar in the Khentei phytogeographical region of Mongolia, is recognized here as a new genus and species of the flora of Mongolia. Arctium differs from other genera of Asteraceae by the hooked apex of the involucral bracts. While A. tomentosum is most similar to A. lappa, it is easily distinguished by the glandular hairs of the corolla limb and the widened inner involucral bracts. Taxonomic notes, a description of the morphology, detailed photos, habitat information, the phenology and a distribution map of A. tomentosum are provided.

Abeliophyllum distichum Nakai, a rare plant with distylous characteristics, is native to certain parts of the Korean Peninsula. It is registered on the IUCN Red List of Threatened Species as a globally endangered plant. This study was conducted to establish an appropriate local conservation management plan suitable for future A. distichum populations by comparing and analyzing the flowering characteristics and population size according to distyly based on the results of quantitative surveys in 14 regions, including 8 areas with native populations of A. distichum and 6 natural monument populations. The number of individuals appearing in each population group was surveyed, and the flowering individuals were identified by style as being either pin or thrum flower types as they were being examined and recorded on the site. In total, 13,130 individuals of A. distichum (7,003 flowering and 6,127 non-flowering individuals) were recorded, but the balance of the number of pin- and thrum-flowered individuals in each population was not significant (p<0.05), indicating an imbalanced state. In particular, the Yeongdong (YD) population was very disproportionate compared to other populations, suggesting that its genetic diversity was low and the possibility of inbreeding was high. The average flowering and fruiting rates by management unit were much higher in the natural monument populations (89.2% and 55.3%, respectively) than in the natural habitat populations (39.0% and 8.5%, respectively). It may be due to a difference in reproductive growth resulting from light inflow into the forest caused by the upper crown closure. The area of occupation (AOO) of A. distichum on the Korean Peninsula covered an area of 23,224.5 m². Although the natural monument population was smaller than the natural habitat population, its density was higher, likely as a result of the periodic management of natural monument populations, where the installation of protective facilities in certain areas restricts population spread. Conservation of A. distichum populations requires removing the natural monument populations suspected of anthropogenic and genetic disturbances and expanding the conservation priority population by designating new protected areas. Although the habitats of natural monument populations are managed by the Cultural Heritage Administration and local governments, there are no agencies that are responsible for managing natural habitat populations. Therefore, institutional improvement in the overall management of A. distichum should be prioritized.

북한식물은 남한이 아닌, 북한 또는 이북지역에 자생하는 식물이며 DMZ자생식물원은 국내 유일의 북한식물 연구센터로서 한반도의 생물다양성 자료구축, 보전, 활용에 관한 연구를 수행하고 있다. 동아시아의 생태계를 이해하고 통일 이후의 황폐화된 북한의 식생 복원 기반 구축 및 산업화 소재 발굴을 위해 북한식물에 관한 체계적인 자료정리와 북한식물 유전자원(표본, 생체, 종자) 수집전략이 요구된다. 본 연구는 국내·외 수목원 및 관련기관의 북한식물 유전자원에 대한 보유 현황을 파악하기 위하여 수행되었다. 조선식물지 등 북한식물 종에 관한 문헌과 전문가 검토를 거쳐 북한식물 DB를 구축하였다. 국내·외 수목원 DB에 북한식물 학명을 검색하여 각 수목원의 북한식물 유전자원 보유 현황을 확인하였다. 북한식물 480 분류군에 대하여 국내 14개 수목원을 포함한 전 세계 6개 대륙, 42개국, 283곳의 수목원을 탐색한 결과 총 432 분류군에 대한 보유 현황을 파악하였다. 189 분류군에 대한 1,475 점의 표본정보를 확보하였으며, 327 분류군에 대한 3,652 건의 생체 및 종자 보유 여부를 확인하였다. 본 연구를 바탕으로 북한식물 유전자원을 체계적으로 수집하여 향후 한반도 생물다양성의 이해를 증진시키고 북한지역 생태계의 보전 및 복원에 기여할 수 있을 것이라 생각한다.

Recently, there has been increasing interest in the use of rain garden systems as environmentally friendly ecological infrastructures for controlling stormwater runoff and managing non-point source pollution and information for the contamination of soil and plants can be essential for sustainable rain garden management. In this study, four rain garden mesocosms, namely single species planting with Rhododendron lateritium, single species planting with Zoysia japonica, mixed planting with R. lateritium and Z. japonica, and control without plants, were tested to investigate the change in concentrations of nutrients (N and P) and heavy metals (Cd, Cu, Pb, and Ni) in the soil and plants used in the rain garden system. The presence of plants resulted in greater nutrient retention in soil and lower potential leaching from the system. All systems showed an increase in the heavy metal concentrations in soil. The concentrations of most heavy metals were found to be higher in the herbaceous plants (Z. japonica) than in the shrubs (R. lateritium). The belowground part (root) had higher heavy metal concentrations than the aboveground part (leaf) but also showed a potential increase in leaves, and hence, careful plant management should be considered during rain garden operation.
