The purpose of this survey was to evaluate herpetofauna including the confirmation of distribution and habitats. And ecological research for the conservation and management at the Mt. Kwangkyo (Suwon in Korea). The results are as follows : 1. During censuses periods Amphibians and Reptiles specimens collected and observed from the Mt. Kwangkyo were classified 10 Families, 13 Genera, 19 Species and 114 Individuals were recorded in this survey. 2. Among 19 species, Protected species and natural monument were not recorded. Meanwhile, Trachymus s. elegance(Exotic species) was founded at the Hakwangkyo small reservoir. 3. Rana rugosa, Hyla japonica, Rana nigromaculata and Rana dybowskii were commonly founded all survey sites(50%). Also, Bombina orientalis was observed Dasulkispa→Helipad course. Bufo bufo gargarizans was Munamvalley→Hyungjaebong and Rana coreana was collected at the Munamvalley and Hakwangkyo small reservoir. Among 8 species amphibians, Rana rugosa was dominant species and next were Hyla japonica and Rana dybowskii. Confirmed 11 Reptiles, Takydromus amuriensis and Elaphe dione were commonly collected all survey sites(18%). Pelodiscus sinensis and Trachymus s. elegance(Exotic species) were observed at the Hakwangkyo small reservoir. Dinodon rufozonatus rufozonatus was Bus station→Norumok course observed, respectively. Agkistrodon ussuriensis was collected 3 survey sites exclusionly Hakwangkyo small reservoir. Also, Reptiles dominant species were Takydromus amuriensis and Elaphe dione. And next were Rhabdohhis tigrinus tigrinus and Agkistrodon ussuriensis. 4. Therefore, At the Mt. Kwangkyo major species of herpetofauna were Rana rugosa, Rana nigromaculata, Rana dybowskii, Hyla japonica, Takydromus amuriensis and Elaphe dione(32%). 5. Species richness and diversity were R'=3.8005 and D'=2.5474. These data showed a little lower than biodiversity index of Mt. Nam(Chungju) and Mt. Chiri National Park. On the other hand, Mt. Chungdung was similar as the Mt. Kwangkyo. Therefore, Mt. Kwangkyo herpetofauna was theoretically complex and stable population structure compared with other survey areas. 6. Valley, wetland(swamp), miscellaneous tree, cultivated field(rice field and farming land) and waste cultivated field were very high herpetofauna biodiversity. So, these ecological environmemt status were must be conservation. 7. In the estimation of appearance frequency, very high(V.A:very abundant,①) were 9 species, including Rana rugosa(47%). (A.B: abundant,②) was none. And (C.O: common,③) were 4 species including Rana coreana(21%). On the other hand, Bombina orientalis, Dinodon rufozonatus rufozonatus, Bufo bufo gargarizans, Pelodiscus sinensis, Trachymus s. elegance and Amphiesma vibakari ruthveni were rare(R.A,⑤)(21%). So, Herpetofauna population density and abundance of the Mt. Kwangkyo was very high(68%).
