최근 범지구적 문제가 되고 있는 지구온난화와 이로 인한 서식처의 환경변화는 고위도 지방의 식물이나 고산식물의 생존에 중대한 문제가 되고 있다. 본 연구는 강원도 태백산맥 고산지대에 분포하는 환경부지정 멸종위기종인 한계령풀 10개 집단에 대해 서식지와 분포 특성을 조사하기 위해 수행되었다. 한계령풀은 고도 940m~1,350m 의 범위에 분포하였으며, 이는 온도기후적으로 온량지수 (WI) 53℃·month~WI 75℃·month에 해당하여 냉온대북부림대에 속한다. 이 종은 5°~23° 경사의 북동사면에 주로 출현하였다. 한계령풀 분포지의 교목층은 신갈나무, 거제수나무, 층층나무, 고로쇠나무가 우점 하였으며, 관목층에는 고추나무, 물참대, 국수나무 등이 우점 하였다. 한계령풀 집단의 초본층 종다양도(Shannon`s Index)는 0.21에서 0.98이며 각 집단에서 한계령풀의 중요치는 개화기에 가장 높은 값을 나타내었다. 서식지의 특성에 대한 본 연구는 한계령풀의 보전과 복원 전략의 수립 결정에 중요한 기초자료로 이용될 수 있을 것이다. Climate change is recognised as the best serious environmental problem in recent time, and high alpine or high latitudinal organisms especially endangered by its change. Leontice microrhyncha is recorded one of the endangered species by the Ministry of Environment Korea. We surveyed ten L. microrhyncha populations distributed at Taebaek Mountains, high mountain area in Kangwon province. L. microrhyncha is distributed 940m~1350m high altitude which equivalent of Warmth Index 53℃·month to 75℃·month, the range of conspicuous cool temperate forest zone. The plant species distributed at slope of 5°~23° on northeast slopes. The vegetation structure at tree layer of L. microrhyncha distribution area is dominated by Quercus mongolica, Betula costata, Cornus controversa, Acer mono in tree layer, and by Staphylea bumalda, Deutzia glabrata, Stephanandra incisa in shrub layer. The species diversity of herb layer of each L. microrhyncha population showed from 0.21 to 0.98, and the importance value of L. microrhyncha in each population was the highest at blooming time of L. microrhyncha. These results will provide the basic information for the development of conservation strategies for this endangered species.

The study for the estimation potential natural vegetation was estimated the occurrence probability distribution using geographic information system (GIS) in Bukhansan National Park. Correlation and factor analysis were analyzed to estimate probability distribution. Coefficients were calculated by logistic regression analysis. Correlation coefficients were significantly at the 0.01 level. Commonality of elevation, annual mean temperature, warmth index and potential evapotranspiration were high value, but topographic index was low value. Communities of over the 0.3 points distribution probability, Quercus mogolica communities were the largest area, 76,940,900 m2, Pinus densiflora communities area was 860,800 m2, Quercus acutissima communities area was 500,100 m2 and Quercus variabilis communities area was 1,000 m2, but Q. aliena, Q. serrata, Carpinus laxiflora and Zelcova serrata communities was not appeared. Therefore, potential national vegetation of Bukhansan national park was likely to be Q. mongolica community, P. densiflora community, Q. acutissima community and Q. variabilis community.

최근 멸종위기 종에 때한 보전, 복원프로그램은 세계적인 추세일 뿐만이 아니라 국내에서도 자연환경보전법으로 보호를 받고 있다. 본 연구는 국내에서 멸종 위기에 처해 있는 붉은점모시나비가 상주-영덕 고속도로 계획노선에 의하여 서식지의 일부를 관통하거나 인접하여 이 지역의 개체군을 대체서식지로의 이주가 결정되었다. 이에 대체서식지의 조성에 앞선 선행 작업으로 위치 선정을 위하여 Mark-Release-Recapture (MRR) 방법으로 가상이동모텔을 적용하여 패치의 연결성을 추정하고 개체생존이주율을 산출하여 대체서식지 위치선정의 평가 자료로 활용하였다. 그 결과, 붉은점모시나비는 패치간의 거리가 약 250m 이내의 범위에서 50% 이상의 연결성과 개체생존이주 가능성을 보였으며, 나비의 이동거리를 추정에서는 평균 300m로 나타났다. 그리고 나비의 분포특성에서는 인접한 여러 개의 서식지 패치를 개체들이 이주를 하면서 순환 발생하는 메타개체군을 이루고 있다. 대체서식지의 위치를 결정하기 위하여 연구 결과에 따른 지역, 해당 지역의 지방자치단체의 추천지역, 그리고 훼손지역의 가치를 상쇄할 수 있을 정도의 중요도가 있는 지역을 예비 선정하였다. 그리고 이 지역들을 나비의 생태, 생태기반환경, 관리방안, 위험요소, 시공요소를 평가를 한 결과, 의성군에서는 5 안(안사면사무소)이 관리방안에서 높은 점수를 얻어 선정되었다. 이번에 평가된 항목에서 나타난 바와 같이 대체서식지의 위치 선정에 있어서는 대체서식지 조성이 가능한 예산의 범위, 서식지 관리주체의 선정, 현지 주민과의 협의 등 여러 가지 문제를 복합적으로 고려하는 것이 높은 비중을 차지하였으며, 생물학, 생태학, 경관생태학, 생물지리학, 생태공학, 조경학, 인문학 등의 다양한 분야의 참여로 얻은 결과물을 융합하여 반영하는 것이 필요하다는 것을 제언하고자 한다. Establishing conservation programs to protect and maintain populations of endangered species are not only a global trend, but also a pursuit endorsed by the Korean Environmental Conservation Act. This study evaluates the feasibility of alternative habitat patches for the endangered butterfly Parnassius bremeri. A portion of habitat of P. bremeri is expected to be fragmented and damaged due to the scheduled construction of the Sangju-Yongduk Highway. A trans fer of the habitat patches of P. bremeri is also scheduled. In order to select an alternative habitat patch, the Mark-Release-Recapture (MRR) method was used to simulate a patch transfer model. The connectedness between habitat are as and the survival of local populations were evaluated for each candidate habitat. It was found that metapopulations with patch distances of <250m showed a 50% connectedness and survival rate in local populations. P. bremeri were expected to migrate at an average distance of 300m. In addition, P. bremeri formed a metapopulation that exhibited intimate patch dynamics that promoted persistence among these patches. Possible candidate habitats including those recommended by local governing bodies were evaluated along with habitats that may counter problems arising from the damage done to the original habitat and habitats that may have a compensatory value equal to that of the original habitat. Based on these criteria, Ansa-myeon township office was selected due to its high scores. This scoring was based on a consideration of a wide range of variables that mark a successful transfer of habitat. These include the amount of funding available, the governing bodies of the possible alternative habitat, and the Expected collaborative effort of local citizens. This decision was collaborated on by incorporating the expertise of various fields of study including biology, ecology, biogeography, ecological engineering, landscape architecture, and social sciences. Therefore, it is suggested that in order to evaluate an alternative habitat for organisms, many social issues as well as ecological issues must be considered.

This study was conducted to find out characterization of spatial distribution of birds observed in river areas. Our bird survey was carried out 4 times at 31 sites from January to September in 2011. A total of 1,609 accumulated individuals belonging to 59 species, 28 families and 11 orders were observed. In the result of spatial autocorrelation analysis using the richness index of the maximum counts of each sites, we confirmed that the distribution of birds in Namdaecheon river was clustered and the tendency of spatial autocorrelation was apparent. The area of each sites within a 200m radius was classified in four biotope categories such as agricultural land, forest, residential area and water area, and the spatial autocorrelation was analysed about four types. In the result of spatial autocorrelation analysis for four biotope categories, all types were showed the positive spatial autocorrelation, but the type of water area was higher than other types. The positive correlation was found between the water area and water birds in statistical significance. However, the forest birds had non-significance values. Therefore, it is appropriate to focus on water birds except for forest birds, when researches of bird distribution in river ecosystem is conducted. The number of bird species and individuals increased as the riverside of water area was to widen. Thus, if the areas of riverside offering the feeding and roosting area increase, it will be accommodated many birds. Also, the areas of riverside should be maintained naturally because it is an important habitats of birds. Our study area is on the outskirts the city of higher rates of forest and agricultural land, it may be unreasonable to apply our results to the whole rivers. If the research about the river flowing around the city will be conducted, it is expected to be useful to the relation study area such as ecological river`s restoration.
