Stream of Hongchon in Gangwon province was well known site for river otter(Lutra lutra) habitat. Because of habitat importance in this region a food analysis was conducted using 478 spraints of the species. A total food was domintnant by fish species occupying 80.5% and the dominant species was Zacco temminckii because of population abundance. Other food items were Amphibians and birds. Summer food was the highest due to its diversity. Gunup and Naechon streams were not different among diversity. Currently the highway construction was underway and we need more information regarding habitat requirement, and management implication for the species in this region.

This study investigate the epidemiological feature of Metagonimus infection in Kangwon-do (province). The average Infection rate of the surveyed inhabitants was 7.8% (83 positives out of 1, 067 examinees) by stool examination; male, 11.4% and female, 3.2%, respectively. The egg positive rate in residents in the Som river area was 7.3%, that of the Chuchon river area 6.3%, the Pyongchang river area 12.8%, the Tong river area 3.8%, the Hongchon river area 9.8%, and the Ohsip stream area of Samchok 8.0%,respectively. The average metacercarial infection rate of genus Metagonimus in the fish was 81.0% (256 positives out of 318 fish). The infected fleshes were Zacco platypus. Zacco teminki, Opswiichthys biens, Squdidis sp., Corqssius carassius, etc. in western Kangwon-do Meanwhile, in the Ohsip stream area of Samchok-gun, eastern costal Kangwon-do, the infected fish were Plecoglossus altivelis and Tribolodon hokonensis. The rats and dogs are infected with the metcercanae obtained from Zacco platypus and Opsariichthys biens, adult worms collected were Miyata type of Metagonimus with some M. takahashii. When infected with metacercariae from Plecoglossus ltivelis, Metagonimus yokogowai was only found. M. yoogawai and Metagonimus Mlyata type were fecund together in Tribolodon hakonenis in Ohsip stream area of Samchok, in the eastern Kangwon-do. The intestinal flukes of genus Metogonimus in western Kangwon-do were Miyata type of MetQnonimuT and M. takahashii transmitting mainly by Zacco platypus and Opsariichtys bidens as a source of infection. In the eastern part of Kangwon province (Ohsip stream area of Samchok), M. yokogowai was mainly distributed by P. altivelis and T. hakonesis, but some T. hakonensis harbored the metacercariae of Miyata type of Metagonimus with those of M. yokogawai.

Present work aims to establish an integrated management system of environmental data base for nine typical wind holes or air holes in Korea. It basically deals with definition, geographical distribution, morphological pattern, physical characteristics and anthropogenic environments of wind hole to propose systematic preservation strategy of their periglacial landscape and flora, which are known to be sensitive to global warming. Wind hole, in which cool air blows out during the summer, but mild air comes out during the winter from a cave or hole, is frequently found on northwest- and north-facing slopes on the terminal point of steep talus, block field, and block stream, and can be categorized into three types, i.e., talus, cave and sink types. Environmental characteristics of nine wind holes are analyzed on the basis of their geology, landform, climate, soil, hydrology, vegetation, road, footpath, land-use, and management system, and relevant DB are prepared. Wind hole areas with unique landscape and ecological values need to be designated as a nature reserve, and zoning of core, buffer, and transitional zones are required for the multi-dimensional preservation of periglacial landscape and ecosystem. Phytogeographical values of glacial relict plants, including mountain cranberry(Vaccinium vitis-idaea) at its global southernmost limit at Bangnaeri wind hole, Hongchon County, Gangwon Province of Korea are discussed in detail as a floristic refugia in connection with climate change during the Pleistocene Epoch and potential in-situ and ex-situ preservation sites in the future.
