This study was conducted to prioritize land purchase in Hwapocheon wetland protection area by reflecting the conservation value of wetlands considering HSI(Habitat Suitability Index) for flagship species. As a result of this study, the flagship species, Oriental White Stork and Been Goose, which can represent the Hwapocheon wetland protection area, were selected through selection criteria and expert feedback. Based on the habitat requirements of the selected flagship species, SI(Suitability Index) for the flagship species was reviewed and the conservation value of wetlands was assessed. The conservation value of the wetlands was divided into five grades from very high to very low. The areas with high conservation value were mainly distributed around wetlands and waters in upstream and downstream of Hwapocheon wetland protection area. The land purchase priorities were divided into five grades by overlapping the thematic maps of the conservation value of wetlands, the economics, and the urgency of restoration. The arable lands which can disrupt wetland ecosystems are analyzed as priority areas where priority purchasing is required. Relatively well-preserved wetlands and areas have low land purchase priorities. This study is meaningful in that biodiversity is considered in land purchase priorities.

In order to restore an ecologically damaged river, freshwater fish which inhabit at the target aquatic ecosystem have a great applicability as one of the essential indicators. Although the informations about the habitat conditions of freshwater fish are key elements reflecting biological, physical, and chemical properties of the aquatic environment, because of the lack of preceding related research and insufficient database with scattered data, they have not been applied effectively for the ecological river restoration projects in Korea. To cope with these problems, based on the nation-wide detailed investigation for domestic freshwater fish habitat conditions, we have selected 70 species considering the possibility for the candidates of flagship species, constructed a database for their population, physical, and chemical habitat properties, and suggested its application methodology for the river restoration projects. In particular, the utilization of the database has been enhanced by the additional statistical analysis to present their resistance and optimum ranges for physical, and chemical habitat properties respectively. It is expected that the database constructed in this study can be utilized for the calculation and evaluation of the appropriate ecological flow rate and target water quality for the selected flagship species (fish), and the basic data for the restoration of river environment.

We identified the diversity, geographical distribution, ecological characteristics of birds, trees, and flowers species designated as local government symbols as a means for understanding public awareness on biodiversity. A total of 114 species including 48 birds, 40 flowers, 36 tree species belonging to 40 orders 59 families 90 genus were designated as natural symbols. Pica pica (L.) in birds, Rhododendron schlippenbachii Maxim. among flowers, have also been designated as symbols. The tree Ginkgo biloba L. was designated with the highest frequency. Local governments located coastal area were selected bird species of the Laridae family and the tree species Camellia japonica L., of Pinaceae as their natural symbols. In contrast, local governments located inland have designated resident bird species such as P. pica and Columba rupestris (Pallas) and flower species from the Ericaceae as natural symbols widely distributed and easily observed throughout South Korea. However, many local governments have designated the same species as a natural symbol based on their size color and public appeal and popularity. The information about the popular species and their ecological traits are useful for establishing the criteria as flagship or iconic species selection and their roles in habitat conservation.

Nannophya pygmaea (commonly known as the scarlet dwarf dragonfly) was designated as an endangered species, level II, by the Ministry of Environment of Korea in 1994; it has been used as a flagship species for the protection and preservation of wetlands. Over 25 sites in Korea have been identified as the habitat of Nannophya pygmaea. However, most of these habitats have proven to be unstable, and there have been subsequent changes in the assemblage structure and organization. Most habitats changed to become grasslands or plain ground, and now only five habitats remain. Although efforts have been made to protect the Nannophya pygmaea as an endangered species, their habitat loss has increased, caused by natural succession and drought. Therefore, we need to make stronger protections in the preservation manual of level II endangered species, particularly Nannophya pygmaea, and its native habitats in Korea.

Fauna of freshwater fish and community structure were investigated at 13 sites in the Deogyusan National Park, Korea from 2014 to 2018. During the period, a total of 8 families, 21 species, and 8,716 individuals of fishes were collected. The number of fish collected over the past five years from 2014 to 2018, were 17 species and 2,280 individuals, 17 species and 1,579 individuals, 17 species 1,905 individuals, 17 species and 1,384 individuals, and 15 species and 1,568 individuals, respectively. There were 13 Korean endemic species including Iksookimia koreensis and Coreoleuciscus splendidus, etc. Only in Wondangcheon Stream, two endangered species were identified, and Hemibarbus mylodon was collected continuously except in 2015, and Pseudopungtungia nigra was observed every year. And two exotic species such as Oncorhynchus masou masou and Oncorhynchus mykiss occurred in Gucheongdongcheon Stream sites. The dominant species was Rhynchocypris oxycephalus and the sub-dominant species was Zacco koreanus and there was no difference by year. The fish community structure of Deogyusan National Park was varied depending on the sites and the year. Most of the survey sites located upper stream where the river structure is Aa river type showed poor community analysis results. On the other hand, the upper-mid stream sites including the Bb type showed better results. As a result, the Wondangcheon Stream sites had the most diverse and stable community structure. Similarity dendrogram was divided into 4 groups, mainly reflecting the characteristics of the habitat. The flagship species of the Deogyusan National Park, Rhynchocypris kumgangensis, was constantly observed during the investigation period. Compared to the previous survey, the number of species increased from 2004 (12 species) and decreased from 2009 (22 species).

This study was conducted to investigate the vegetation structure of Zone 2 of Mudeungsan National Park Old Trail. A total of 60 survey plots were installed to survey the forest structure, and TWINSPAN and DCA analysis classified them into 5 communities. The community I was classified into Deciduous broad-leaf tree, II into Pinus densiflora-Quercus serrata, III into Quercus serrata, IV into Lindera erythrocarpa, and V into Quercus mongolica. The grouped communities showed some differences in species compositions according to elevation. In the four communities except for community IV, Styrax japonicus and Sasa borealis formed a dominant population in understory layers and in shrub layers, respectively, and the current community forms are expected to be maintained. Monitoring of vegetation succession of lower vegetation after temporary flowering and withering in the ridges developed in the shrub layers in communities II through IV is required. In the long-term aspect, the competition between the pine tree and oak tree communities requires observation of a decrease in the power of the pine tree community. Mudeungsan National Park's Old Trail ecologically valuable as it has a vegetation structure that is distinctively classified according to altitude and is a habitat of Lindera sericea, the flagship species of Mudeungsan National Park. It means that the excellent forest ecosystem of Old Trail must be conserved through sustainable utilization.
