절경이과의 Plantago aristata Michx.(국명신칭: 긴포꽃질경이)가 경기도 고양시 한강하구에 자라고 있는 것으로 처음 확인되었다. 이 귀화식물은 선형인 잎(길이 9-20 cm, 폭 5-8 mm), 긴 선형의 포(길이 약 2.5 cm), 큰 흰꽃(직경 4-6 mm)으로 다른 한반도 질경이속 식물들과 구별된다. 북미 원산인 본 종은 인근 국가인 일본과 중국에도 유입되어 퍼져나가고 있는 것으로 보고되어 있다. 확증표본은 서울대학교 석엽표본관(SNU)에 소장하였다. We reported that an alien species of Plantaginaceae, Plantago aristata Michx. from North America, grows at the Han-River estuary in Go-Yang City, Kyunggi Province. This species is easily distinguished from others in Korea by its linear leaves, cylindrical spikes with long linear bracts at base, and relatively large flowers of ca. 4-6 mm in diameter. We called the species as gin-po-ggot-jil-kyung-i as a local name. Plantago aristata is known to be very invasive and has been already introduced to Japan and China.

Korean fir(Abies koreana E.H.Wilson 1920), endemic tree species of Korean peninsula, is considered as vulnerable and endangered species to recent rapid environmental changes such as land use and climate change. There are limited activities and efforts to find natural habitats of Korean fir for conservation of the species and habitats. In this study, by applying SDMs (Species Distribution Models) based on climate and topographic factors of Korean fir, we developed Korean fir’s predicted distribution model and explored novel natural habitats. In Mt. Shinbulsan, Youngnam region and Mt. Songnisan, we could find korean fir’s two novel habitat and the former was the warmest(13°C in annual mean temperature), the driest(1,200mm∼1,600mm in annual rainfall) and relatively low altitude environment among Korean fir’s habitats in Korea. The result of SDMs did not include mountain areas of Gangwon-do as habitats of A. nephrolepis, because there were different contributions of key habitat environment factors, summer rainfall, winter mean temperature and winter rainfall, between A. koreana and A. nephrolepis. Our results raise modification of other distribution models on Korean fir. Novel habitat of Korean fir in Mt. Shinbulsan revealed similar habitat affinity of the species, ridgy and rocky site, with other habitats in Korea. Our results also suggest potential areas for creation of Korea fir’s alternative habitats through species reintroduction in landscape and ecosystem level.

This study surveys and analyzes the ecology of Gangseo area to be developed near Nakdonggang River and West Nakdonggang River in Busan - before its development. With the result of the surveys as its basis, the study also finds ways to conserve the area``s bird habitats in response to the planned development. According to the site surveys over four seasons, West Nakdonggang River which is near the targeted development area is a wintering ground for migratory birds. Some representative bird types in this area are ducks, geese, and other water birds. There are even six legally protected species. The average altitude of their flight is calculated to be 92.4±18.8m and the main purpose for the migration is determined to be for food. According to evalution of the conservation value of the area, Nakdonggang River and West Nakdonggang River turns out to have the highest conservation value. Other areas are developable as long as it was environmentally friendly. Therefore, this study suggests incorporation of ecological parks and biotopes within the targeted development area along with the proposal for spaces in the surroundings where the wintering birds can rest and feed. Especially for the wintering birds that rest at Nakdonggang River and West Nakdonggang River, their flight direction and pattern was examined to determine that their resting ground should be located 50~100m off of the river bank. Furthermore, this study proposes ways to maximize bird habitat by building ecological corridors between the agricultural channel and other small streams in the targeted development area and the habitats in the surroundings. Lastly, the study suggests the construction of low buildings, at most 20m in height, near Nakdonggang River and West Nakdonggang River considering the birds`` flight altitude and direction.

This study was carried out to suggest fundamental concepts and data ideas for biodiversity and confrontation strategy on global environmental changes by analyzing geomorphic milieu and geotop in Mt. Jeombong experimental forest. Elements of landform were classified as landform sets by scale. Scale for classification could be decide on four categories. We could classify landforms which scale zero is seven elements, scale one is twelve elements, scale two is fifteen elements, scale three is twenty nine elements. Especially mountain wetlands were classed as valley and channel types in Mt. Jeombong. Geotop by clustering methods could be four spatial units as 2, 3, 5, and 7 classes, and analyzed geodiversity as landform sets for explanation of vegetation distribution. Rate of rise of temperature was 0.031°C per year, change ratio was increased 1.25°C, and also precipitation was increased 320mm during forty year(from year 1973 to year 2012). The result of this research can be affordable to provide information for forest management of mountainous areas.
