  • Sustainable habitats play a significant role in determining the survival and habitat preservation of endangered species. To conserve the endangered species Iris dichotoma Pall. and its habitat in Taeanhaean National Park, we collected seeds from a natural population and germinated and propagated them in a greenhouse. In 2019, the propagated individuals of I. dichotoma were transplanted at two study sites in Taeanhaean National Park. After conservation translocation, annual monitoring was conducted from 2020 to 2022, and factors related to the survival and growth of I. dichotoma (clonal propagation rate [%], the flowering rate [%], the population density [individual/m2], the maximum leaf bundle length [height; cm], the maximum leaf bundle width [cm], and the pedicel length [cm]) were measured. According to the results of the monitoring of the flowering and fruiting periods for three years after transplantation, 82.4% of individuals in total were found to have survived. During 2020 to 2022, the mean population density (individual/m2) increased from 0.36 to 0.42 and the size of the leaf bundle length and the width both decreased compared to the corresponding figures in 2019 (p < 0.05). According to the findings here, the transplanted population of I. dichotoma is considered to have adapted successfully to its new site in Taeanhaean National Park.

  • Respectful Recognition of Life is a broad concept that includes a mindset that values oneself, others, animals and plants, does not harm them, and protects the environment. Prior research examined the relationship between companion animals and the perception of respect for life. In this study, we investigated and analyzed whether the development of interactive game content with virtual pets in augmented reality has the effect of improving the perception of respect for life. To this end, six contents were developed by referring to the daily routine of a panda keeper, an endangered species. As a result of the experiment, it was confirmed that the effect of recognizing respect for life is similarly applied to the interaction with virtual pets, and it is expected that it will be able to satisfy the needs of users who want to keep endangered species as pets.

  • We investigated vascular plants of Aphaedo Island in Shinan-gun, Jeollanam-do, Korea. By referring to voucher specimens collected over the course of 28 days from May of 2011 to March of 2016, a total of 451 taxa were identified and grouped into 102 families, 294 genera, 413 species, 6 subspecies, 30 varieties, and 2 forms, of which 9 taxa were classified as endangered or rare, including Albizia kalkora, Salomonia oblongifolia, and Centranthera cochinchinensis var. lutea. A total of 59 taxa were identified as regional indicator plants. Six taxa were endemic to Korea, including Hepatica insularis, Indigofera koreana, and Lespedeza maritima. Three taxa (Rumex acetosella, Aster pilosus, and Hypochaeris radicata) among 52 naturalized taxa were ecosystem-disturbing plants as designated by the Ministry of the Environment. The results of preceding floristic research before and after the inauguration of the Aphaedaegyo (bridge) were used to analyze changes in the number of naturalized species on Aphaedo Island.

  • We investigated the flora of Imja-do(Isl.), an island of the Shinan archipelago, located in Imja-myeon, Shinan-gun, Jollanamo-do and discussed the vascular plants found there. Twenty-four separate field trips (100days) were completed from August of 1997 to October of 2009. As a result, we identified the distribution of 526 taxa in Imja-do(Isl.), comprising 112 families, 331 genera, 463 species, 1 subspecies, 60 varieties, and 2 forms. There are a total of 78 taxa of floristic regional indicator plants and one taxon of level II endangered species, Millettia japonica, as designated by the Korean Ministry of the Environment. The floristic regional indicator plants are as follows; four taxa of level V such as Utricularia bifida, two taxa of level IV such as Cladium chinense, 14 taxa of level III such as Aletris spicata, three taxa of level II, and 55 taxa of level I. In addition, one endangered species (EN), Nymphoides coreana, five vulnerable species (VU),such as Ilex cornuta, and three near-threatened species (NT) such as Utricula riaracemosa, were found in the investigated area. The plants of Imja-do(Isl.) are classified into four types based on the plant geographical origin, as follows: 1) boreal plants advancing southward in a glacial period, 2) temperate plants spreading eastward from the Himalayas and China to Japan passing through the south coast of Korea, 3) subtropical plants, and 4) indigenously developed endemic species of the warm-temperate region of East Asia.
