Accurate information on habitat distribution of protected fauna is essential for the habitat management of Korea, a country with very high development pressure. The objectives of this study were to develop a habitat suitability model of wild boar based on GIS and logistic regression, and to create habitat distribution map, and to prepare the basis for habitat management of our country s endangered and protected species. The modeling process of this restudyarch had following three steps. First, GIS database of environmental factors related to use and availability of wild boar habitat were built. Wild boar locations were collected by Radio-Telemetry and GPS. Second, environmental factors affecting the habitat use and availability of wild boars were identified through chi-square test. Third, habitat suitability model based on logistic regression were developed, and the validity of the model was tested. Finally , habitat assessment map was created by utilizing a rule-based approach. The results of the study were as folos. First , distinct difference in wild boar habitat use by season and habitat types were found, however, no difference in wild boar habiat use by season and habitat types were found , however, ho difference by sex and activity types were found. Second, it was found, through habitat availability analysis, that elevation , aspect , forest type, and forest age were significant natural environmental factors affecting wild boar hatibate selection, but the effects of slope, ridge/valley, water, and solar radiation could not be identified, Finally, the habitat at cutoff value of 0.5. The model validation showed that inside validation site had the classification accuracy of 73.07% for total habitat and 80.00% for cover habitat , and outside validation site had the classification accuracy of 75.00% for total habitat.

The habitat composition in the Han-river estuary, where white-naped crane(Grus vipio; endangered migrating bird) spend winter, was analysed by the geographic information system(GIS). And the habitat use pattern of white-naped crane collected by satellite tracking method was analysed. The % composition of seven habitat categories of land cover classification was compared for the buffers of radii 100 m, 200 m, 500 m, and 1 km, respectively, around the white-naped crane position point(n=228), and the statistical analysis was done using chi-square test. The results showed no selective use of habitat area by white-naped crane in the buffers of 100 m, 200 m and 500 m, but showed clear selection of habitat use (p < 0.05) in the case of 1 km buffer.

본 연구는 2002년 10월부터 2003년 9월까지 경상북도 봉화군 운곡천을 대상으로 수달의 배설물 및 배설지 등의 흔적조사를 통해 얻은 GPS좌표를 중심으로 하여 수치지도 및 현장조사에서 얻은 정보를 Arc/view를 이용해 수달의 최적 서식지분석에 이용하였다. 분석결과 수달의 서식지 이용에는 먹이자원인 어류의 종다양도와 풍부도가 깊은 연관을 맺고 있으며 식생 등의 서식환경이 밀접한 연관을 맺고 있음을 확인하였다 또한, 밀집된 주거지 등 인간의 간섭은 수달의 서식지 이용에 교란요인으로 작용한다는 것을 알 수 있었다. 본 연구는 수달의 보전 및 관리를 위한 적합 서식지를 선정하기 위해 GIS기법의 활용에 대한 적용 가능성을 평가하였다.

The damage and fragmentation of habitat due to urbanization pose a great threat to amphibians worldwide. To understand the effect of urbanization on the distribution and abundance of Hyla japonica, we measured their population sizes by listening frog calling and investigated the habitat their population sizes and land use in the 18 rice paddy fields located in Incheon and its surroundings. Abundance of H. japonica was 0 - 17 male adults / habitat or 0 - 41 male adults / ha in Incheon. The number of the frog was increased as the distance between the habitat and the road became longer or the ratio of circumstance / area of the habitat increased. Unlike the general prediction, the density of H. japonica showed a negative correlation with the size of the habitat and a positive correlation with the surrounding land use intensity. Our results suggested that H. japonica could be concentrated in a narrow habitat due to the habitat size decrease and the periphery development according to the urbanizaion.

건강한 수생태계 유지·관리를 위하여 다양한 수생생물을 활용한 각 분류군의 종별 서식지 적합도 지수 DB 구축의 필요성이 증대되고 있다. 대부분의 수생생물의 경우 문헌 연구를 통해 서식지 적합도 지수를 산정하기는 어려우므로 현장 모니터링 자료를 이용한 어류, 저서생물 등의 서식지 적합도 지수를 산정하여 하천 복원 및 수생생물의 서식에 필요한 생태유량 결정에 중요한 인자로 활용하고 있다. 국내에서 하천 건강성 평가 등을 통해 수계별 다양한 조사를 수행하고 있으나 대부분의 연구는 출현 종 분류 및 출현율 등에 국한되어 있다. 또한, 부족한 현장 모니터링 자료로 인해 서식지 적합도 지수를 산정하기 위한 객관적이고 과학적인 물리적 인자를 도출하기 어려운 실정이며, 이는 전문가의 경험을 바탕으로 한 주관적 판단으로 이어져 결과의 신뢰성 측면에서 한계가 있을 수 있다. 따라서, 수계별 장기적인 모니터링 및 자료 구축을 위한 연구가 필요하며, 기존 서식지 적합도 지수 산정에 관한 방법의 장단점을 명확히 파악하여 국내 하천환경 및 특성에 적합한 서식지 적합도 지수 구축이 반드시 선행되어야 할 것이다.

This Study was Analysis about Habitat of Eurasian otter Lutra lutra L. In October 2002 during September 2003, Otter Spraints and Sprainting site were searched in river Unkog of North-Kyongsang Province for taking the GPS coordinates. For Analysis of habitat, This data were used by Arcview ver. 3.2 with 1/25000 Topology Map and Other Field data. The result of Habitat Analysis meant that Habitat use was strongly related to Fish diversity and richness also vegetation and cover were connected with otter habitat. In other hand, The Human interferences including dense structures like House acted as factor of disturbance. This study suggest that The preceding about Suitable habitat having free of Human disturbance, abundant fish and good vegetation is essential In Trial for Conservation or Recovery of Otter like Trans-location.

This study aims at favorable environmental conditions by river otter residing in Hongcheon river ecosystems using spraints along the river. Otter spraints were indicative of habitat use pattern and marking a territory in the areas. Nae-chon and Kuneob-chon river otter spraints were collected totaling 478 with 8 times during 2009-2011, and based on the number river use patterns were analyzed with the technique of index of dispersion. Results with larger than one indicated that river otter habitat use pattern were not random; instead they used preferred areas for habitat use. 'I' values greater than one indicate a clumped distribution and lower than one indicate random distribution. This study also demonstrated that we need a sophiscated linear model that should be developed to identify key habitat elements in river ecosystems.

우리나라 특히 서ㆍ남해안은 전형적인 리아스식 해안으로 해안선 출입이 잦아 해안의 대표적인 지형들이 골고루 발달해 있는 곳이며, 해안생물자원도 풍부한 지역이다. 종래의 생태계 조사방법은 종목록을 작성하는 수준이었기 때문에 자연자원과 생태계 보존 및 관리에 필요한 해안생태계의 서식지 유형을 분류하여 지도화하는 작업이 우선적으로 이루어져야 한다. 이 연구는 태안해안국립공원 지역을 대상으로 다음의 세가지 연구를 시행하였다. 첫째, 해안생물의 서식 기반이 되는 물리적 요소인 기질, 경사도, 파랑에너지에 입각하여 서식지 유형을 분류하였다 둘째, 해안의 생태계 보존 및 관리에 영향을 미치는 토지이용 현황을 원격탐사를 이용하여 분류하였다. 셋째, 서식지와 토지이용을 결합하여 암석해안과 갯벌(모래, 펄)의 생태계 단위를 설정하였다. 이러한 생태계 단위는 생태적으로 관리전략을 세울 수 있는 토대가 될 수 있다.

This study examined habitat fragmentation that has occurred in Paju and Yeoncheon, the two border municipalities between North and South Korea in Gyeonggi-do (province) during the last 17 years using various landscape metrics. We 1) classified grass and agricultural habitats and forest habitats from two Landsat TM images collected in 1990 and 2007, and 2) compared the percentage of class area, patch density, mean patch area, and mean perimeter area ratio for the two habitat types between the two time points. Both types of habitats has been severely fragmented due to urban development in the last 17 years. The increased patch density and decreased mean habitat area are attributed to the construction of roads and railroads that separate a large habitat to many small pieces. The increased mean perimeter area ratio also indicates that the habitat fragmentation extended areas that are affected by the edge effect and so less suitable for interior species. A habitat conservation plan is urgently needed to minimize habitat fragmentation from developments that are expected to soon occur in the north and south Korean border.

The objective of this research was to develop habitat suitability models for wild boar (Sus Scrafa) in Mt. Sulak National Park and Mt. Jumbong Natural Forest Reserve. The study area is covered-with climax temperate hardwood forests ot'mainly Mongolian oak ($\textit{Quercus mongolica}$), and has diverse wildlife species including wild boars. Three suitability models - summer, fall, and annual models - were developed. These models were based on slope, aspect, forest types, forest year classes, distance from streams and trails. Habitat data collected through telemetry were used for the models. The accuracy of the models was tested by comparing observed traces of wild boar in Mt. Jurnbong, and most traces were on suitable areas on the suitability maps.
