A faunistic study on the terrestrial insects of Unmunsan(located in the boundary between Unmun-myeon Chongdo-gun Gyoungbuk and Sannae-myeon Milyang-si Gyoungnam, Korea) was carried out during November, 2007 to October, 2008. It was found that terrestrial insects distributed in nature sabbatical area of Unmunsan, were composed of 14 orders, 151 families, 610 genera, 756 species. In this study, it shows the dominances of taxa from site U1 to U4, in order of the following: Lepidoptera, Coleoptera and Hymenoptera. Lepidoptera with 252 species and 33.3% show the highest dominance and Coleoptera follows the former with 182 species and 24.1% in dominance. The rare Luciola lateralis Motschulsky and Spindasis takanonis (Matsumura) which is designated as the endangered species level II by the Ministry of Environment inhabit in Unmunsan.

The native vascular plants, growing at the nature sabbatical application area, were classified & recorded as a total of 407 taxa, 83 families, 235 genera, 338 species, 3 subspecies, 54 varieties and 12 forms. The endangered wild plants were recorded as 2 taxa (Paeonia obovata and Lilium cernuum) and the Korean endemic plants were observed to exist in the formation of 21 taxa, 13 families, 19 genera, 15 species, 4 varieties and 2 forms including Cephalotaxus koreana, Pseudostellaria coreana, Aconitum pseudo-laeve, Clematis trichotoma, Geranium koreanum for. hirsutum, Thalictrum uchiyamai. The floristic special plants consist of 55 taxa, 35 families, 50 genera, 51 species, 4 varieties(Crypsinus hastatus, Cimicifuga heracleifolia, Paeonia obovata, Lilium cernuum and Gastrodia elata etc.). The naturalized plants comprise 10 taxa, 4 families, 10 genera, 9 species and 1 variety. The ratio of Urbanization and Naturalized Index was 3.51% and 2.46%, respectively. Life form spectra were displayed as H-R5-D4-e type.

This study investigated mammal fauna in the sabbatical area of Mt. Unmun, Kyungsangbuk-do from December, 2007 to September, 2009. A total of 24 species belonging to 11 Families, 6 Orders, were identified in the survey area. Dominant species were as follows: Chinese water deer (Hydropotes inermis), Siberian chipmunk (Tamias sibiricus), Korean mole (Mogera wogura), and East Asian field mouse (Apodemus peninsulae). Especially, four Legal Protection Species specified as National Monument (NM) and Endangered Species (ES) found in this survey were as follows: Flying squirrel (Petromys volans; NM #328 and ES level II), Eurasian otter (Lutra lutra; NM #330 and ES level I), Leopard cat (Prionailurus bengalensis; ES level II) and Marten (Martes flavigula; ES level II). These results on the geographical distribution of various mammal species and Legal Protection Species indicate that this area is a valuable ecosystem for native mammal species. On the other hand, many feral cats were also found and specified as a management species. The results of this study show that further long-term investigation and management plan are needed to protect against harmful species and maintain the native ecosystem of Mt. Unmun.

The purpose of this study is to suggest vegetation management method as the cultural landscape forest of Dongbaek Island which is the district monument. The study area was $20,000m^2$ around the peak area in management as the nature sabbatical area. Vegetation structure type was classified with the criteria of topography, vegetation, management and the management plan was derived from the vegetation structure analysis according to the types. Vegetation structure types were Management-Camellia japonica, Non-management-Eurya japonica, Non-management-Rugged area-Eurya japonica. As the result of vegetation structure, Pinus thunbergii dominated in canopy layer and Camellia japonica and Eurya japonica dominated in Type I and in Type II and III, respectively. Especially, Machilus thunbergii as the climax species in the warm temperate forest were distributed centering shrubs, and as the result of distribution of diameter of breast height, middle size of Celtis sinensis and Machilus thunbergii were distributed in type I, II. Machilus thunbergii were distributed in range of 4 to 44 individuals through the all types. Mean age of canopy layer was 66 year-old and sub-canopy layer was 22.9 year-old. Shanon's species diversity was analysed from 0.5472 to 0.8646. As the vegetation management direction of Dongbaek island, managed Camellia japonica forest was suggested to maintain the regular management and non-managed Eurya japonica forest was required to remove the Eurya japonica and plant the Camellia japonica. In case of non managed Eurya japonica forest in rugged area, vegetation succession was required to laurel forest.

A biological assessment of water quality was carried out in Unmunsan County Park from November 2007 to September 2008. The benthic macroinvertebrates collected from the surveyed sites were composed of 140 species, 106 genera, 61 families, 13 orders, 5 classes and 4 phyla. The dominant species in all the survey areas was Goerodes KUa of Trichoptera. The dominance index(DI) showed the highest as 0.553 at site 2 and the lowest as 0.354 at site 7. The species diversity index(H') showed the highest as 2.18 at site 7 and the lowest as 1.75 at site 2. Ecological score of benthic macroinvertebrate(ESB) showed the highest as 85 at site 4 and site 7 and the lowest as 51 at site 5. As a result, the areas 4 and 7 needed to be designated as the highest protection area, and the area 5 as the protection area. Besides, the water quality, based on the ecological indicators of benthic macroinvertebrate community, turned out to be oligosaprobic in the whole survey areas.
