The purpose of this study is to provide an protected wildlife species and potential habitats in Seoul through the overall present status of the species which live in Seoul. This study was performed in Seoul, the entire area of which is 605.52 $km^2$. We analyzed a total of 57 studies, including academic papers and research reports, for the natural ecology in Seoul. As for the results from the study, it was found that a total 1,907 species from 5 taxa were inhabiting and growing within the area. Among the total, plants of 1,656 species accounted for 86.7%, 197 species of wild birds made up 10.3%, 29 species of amphibians and reptiles consisted of 1.5%, and 27 species of mammalia totaled 1.4%. A total of 440 species except foreign species and species legally preserved by the Ministry of Environment, common species and uncertain species were selected as primary candidates. By taxon, it shows 212 species of plants, 180 species of wild birds, 24 species of mammalia, and 24 species of amphibians and reptiles. For extensive research subjects and research data limited in certain insect family, analysis by literature for discovered insects was excluded. The selection criteria for the second candidate species was based on extinction crisis, rarity, historicity and locality, academic value, habitat specificity, etc. The second candidate species from the primary species were selected through taxon experts' evaluations. As for the results of the selection of the second candidates, a total 77 species were selected through the experts' evaluations. Each species by taxon was 25 species for plants, 21 species for wild birds, 5 for mammalia, 10 for amphibians and reptiles and 16 species for insects. A site investigation for the second candidates was conducted to select the final candidate species. For the target areas, the habitats of the second candidates given by the literature and 46 potential areas in Seoul, which show good natural resistance, were finally selected. From the result of the site investigation, it was found that 14 species of plants, 19 species of wild birds, 2 species of mammalia, 4 species of amphibians and reptiles, and 16 species of insects were actually inhabiting Seoul; thus, the final 55 protected species were selected.

Reptiles, unlike mammals, have been considered to be unsuitable hosts of Trichinella spp., though larvae have been detected in their muscles and human outbreaks related to their consumption have, in fact, occurred. Herein we report 2 Korean cases of trichinosis, possibly transmitted via consumption of reptile meat. Both patients suffered from myalgia, headache, and facial edema. Laboratory examinations revealed leukocytosis with eosinophilia (54% and 39%, respectively) and elevated creatinine phosphokinase. ELISA was performed under the suspicion of trichinosis, showing positivity at the 29th and 60th day post-infection. Since they had consumed raw soft-shelled turtle meat, turtle was strongly suggested to be an infection source of trichinosis in Korea next to the wild boar and badger.

Rice Fields have provided large areas of open water for centuries in regions with a variety of rice-growing cultures, and, in addition to producing rice also provide other animal and/or plant food sources and medicinal plants, thus acting as wetland systems and helping to sustain livelihoods and human well-being in these regions. Also rice fields in many parts of the world support important wetland biodiversity, such as reptiles, amphibians, fish, crustacean, insects and mollusca, and play a significant ole in water-bird flyways and the conservation of water-bird populations. The purpose of this study is to find a way conservation of rice fields in connection with paddies's laws, for example, amend the Conservation of Wetlands Law or legislate for the conservation of paddies.

Before the construction of Hantangang dam, we surveyed vertebrate fauna along the Hantangang River and collected samples. We collected 248 specimens (1,394 individuals) of 41 fish species from 10 families in four orders, including 17 endemic species and 5 endangered species. In our herpetofauna survey, we collected 47 amphibian samples of 10 species from 5 families in 2 orders, and 19 reptile samples of 5 species from 2 families in 1 order. We observed 25 species of bird (6 orders, 14 families) inclulding collection of 51 bird specimens (10 species from 5 families in 1 order). We collected 91 mammals of 6 species, and identified 7 species from field sign and direct observation from a total of 10 families in 5 orders. This collection and list comprise the final vertebrate faunal survey of the Hantangang region, and will provide basic scientific information for future research on conservation and restoration of the region.

In order to assess ecologically for the restored detention basin in Joogyo creek, this study carried out a monitoring on the ecosystem of the detention basin. The study site was a small detention basin with an area $6,350m^2$, which had been established in March, 2004. The monitoring started in August and November, 2007. Terrestrial, riparian, and aquatic plants species have increased about 2 times at detention basin compared to that of streamside. Mammals, birds, reptiles, amphibians, aquatic insects and crustaceans were found more in species at detention basin, and especially there were a lot of more fish species. From the results, it seemed that various terrestrial, riparian, and aquatic ecosystem were made in the small detention basin.

1. The isolated strips of guinea-pig, fowl and reptiles (snake and tortoise) showed consistenly excitatory responses to $PGE_1\;and\;E_2$, which were dose-dependent. 2. Frog intestine revealed inhibitory responses to both $PGE_1\;and\;PGE_2$ except a small of $PGE_2$ (1-10 ng/ml) caused slight contraction. 3. The intestines of pieces showed inconsistent responses to $PGE_1\;and\;E_2$. In fresh-water fish(carp), $PGE_1$ produced relaxation under the dose of 50 ng/ml, and contraction by the large doses, but $PGE_2$ consistently caused contraction in dose-dependent manner. However, the strips of sea-water fish revealed the different responses to PGE compound: $PGE_1$ caused relaxation and $PGE_2$ conversly contraction even though in small degree. 4. These results that there are genera differences in the responses of the longitudinal strips of intestine to $PGE_1\;and\;PGE_2$ was assumed to be possibly correlated with evolutionally primitive function of gut.

This study was conducted to determine the geographical distribution and habitat for Rana catesbeiana and Trachemys scripta elegans in order to obtain the current basic data on biota needed for establishing a database on non-indigenous species(NIS) in Jeju-do and to develop management plans applicable to Jeju, starting from March 2005 until May 2006. As a result of an inspection, it was found that the habitat for R. catesbeiana in Jeju includes Hankyeong-myeon, Daejeong-eup, and Ahndeok-myeon. These areas are all located on the western side of Jeju-do, and considered to have favorable conditions for R. catesbeiana to inhabit. Thus, it is unlikely that the population of R. catesbeiana will possibly decrease; what's worse, there exists even a risk that it could not only expand to other regions but also do damage to the population of native insecta, fishes, amphibians and reptiles, so this terrible species ought to be exterminated. More than 92 individuals of T. scripta elegans species were found to inhabit in 15 ponds around Jeju Island. T. scripta elegans. as the topmost predator, could destruct the pond ecosystem, and also cause a problem of water pollution due to its excrement. Counter-measures against T. scripta elegans could include publicity activities encouraging self-control of the release of captive T. scripta elegans, extermination plans using its ecological habits, and sign-posting publicizing its hazard to healthy ecosystem at the areas with high population density of T. scripta elegans or at its habitats with high foot traffic, together with the continuous management of NIS(none-indigenous species).

Amphibian and Reptilian specimens which were surveyed in Gyebangsan during both from Apr. 26, 1995 to Oct. 15, 1995 and from Apr. 13, 1996 to July 28, 1996 were observed 9 Species in 5 Families on 2 Orders and 10 Species in 3 Families, 5 Fimilies, 9 Species and Reptiles were 2 Suborders, 3 Families on 2 Suborders, respectively. Bombina orientalis was revealed dominant species and Bufo stejnegeri was distributed abundant on this investigation area than other survey studies. Relatively large number of larvae of Rana dybowskii were found among the stream and small ponds at the Suchung-gol valley. There were 5 species of Specific wildlife species in Korea as Hynobius leechii, Rana dybowskii, Onchodactylus fischeri, Bufo stejnegeri and Bufo bufo gargarizans. Meanwhile Bufo stejnegeri were endemic species in Korea. 6 Species among 10 Species which were observed Reptiles in this survey Scincella laterale laterale, Dinodon rufozonatus rufozonatus, Agkistrodon brevicaudus, Agkistrodon saxatilis, Amphiesma vibakari ruthveni and Enhydris rufodorsata were Specific wildlife in Korea. Scincella laterale laterale and Takydromus amuriensis were habitated very abundant in Suchung-gol region. Habitat density of Takydromus amureinsis at Suchung-gol region was 36 individuals/ha. Total number of pressed to death individuals caused by press on the road from May to July, 1995 were 404 specimens in 10 Species. The 1,2,3 and 4 Stations where were found the largest number of death individuals caused by press on the road should considered to construct Eco-corridor to reduced the death individuals with small pipes beneath the road as a migration route. Onchodactylus fischeri have around 500m as moving distance and home range for lifelong and it were the climax of broad-leaved tree and highly moisture area that abundantly region of Onchodactylus fischeri.

In this study, the faunae before and after creating the Solbangjuk Wetland Ecological Park located in Jecheon-city were compared. As a result, the change of the fauna according to the creation of the park showed the phenomenon that the species having the strong wilderness are reduced and the rate of general species become higher. In addition, the species which receive the restrictions for moving such as mammals, amphibians and reptiles are being gradually decreased by the increased visitors owing to the creation of the park. Moreover because there was the case where group of fishes have died caused by discharging and working the water in the reservoir during the creation process of the park, the supplementation work for this is required. However, it showed that the insects sucking the honey from flowers in the composed flower garden after creating the park, and the aquatic insects which live in this park that the stable water system for the growth of wetland plants is maintained, are increased, respectively. As a result of this survey, because the reservoir for agriculture adjacent to the residential area is generally small, the securing of the habitat space for the wild animals living in this park when creating the ecological parks seems to be necessary. The countermeasure should be considered so that some areas of the reservoir can be maintained in their natural state by adjusting the visitors' trails and the position of facilities for in order to secure the habitat of the wild animals.
