Tonggo-san(1066.5m) is located at 36° 53 00 - 36 55 00 in latitude, at 129° 10 30 - 129° 13 00 in longitude and on Seo-myeon, Uljin-gun and Subi-myeon, Yeongyang-gun in Gyeongsangbuk-do. Tonggo-san shows the typical vegetation patterns including the middle area of temperate region of Korea represented by the secondary forests of Quercus mongolica and Q. dentata. There was no detailed result on the flora and vegetation of Tonggo-san until now. Therefore, we tried to discuss on the distribution and availability of vascular plants including economical plants. Also, we could discuss the especialized plants and their distributions according to the criteria by the Ministry of Environment. The results of plant collection and their investigation from April in 2001 to November in 2001 are as follows : The vascular plants consist of total 565 taxa; 17 forms, 82 varieties, 466 species, 297 genera, 94 families,37 orders, 4 classes, 2 subphyla. In this area, there were a lot of useful economic plants such as 232 taxa(41%) of edible source, 222 taxa(39%) of forage source, 183 taxa(32%) of medicinal source, and 72 taxa(12%) of ornamental source, 15 taxa(2.6%) timber source, 7 taxa(1.2%) industrial raw material source respectively. Among them, the Korean endemic plants were 22 taxa(3.9% among total 565 taxa); 1 forms, 2 varieties, 19 species, 22 genera, 16 families. And rare and endangered plants was 1 taxa; Astragatus membranaceus. Also, the naturalized plants were 19 taxa(3.4% among total 565 taxa and 10.4% among the total naturalized plants in Korea).

한국 특산식물인 미선나무 1종을 대상으로 세포학적 조사를 수행한 결과 2n=28로 x=14의 2배수성 식물로 조사되었다. 염색체 크기는 $1.00{\mu}m$에서 $2.03{\mu}m$의 크기를 보였고, 그 크기는 연속적인 상태를 나타내었다. 본 연구에서 밝혀진 세포학적 형질인 기본염색체수, 크기의 연속성, 배수성 및 핵형에 있어 개나리속 식물과 거의 유사한 특징을 갖는 것으로 밝혀져 이들 속간에 세포학적으로 유연관계가 밀접한 것으로 판단되며, 미선나무속과 개나리속은 동일족에 포함되는 것이 타당할 것으로 사료된다. Cytological characteristics of Abeliophyllum distichum (Oleaceae), endemic to Korea, was examined. Somatic chromosome numbers was 2n = 28 which corresponds to diploid based on x=14. Chromosome length was varied continuously from $1.00{\mu}m$ to $2.03{\mu}m$. Karyotype of Abeliophyllum distichum was investigated in this study for the first time. The cytological characteristics including basic chromosome number, continuous variation of chromosome length, diploid and karyotype were similar to those of the genus Forsythia, which indicated the close relationship between Abeliophyllum and Forsythia, and consequently the two genera seemed to be included to same tribe.

This study was conducted to develop a habitat assessment system for the endangered wildlife II Kirengeshoma koreana Nakai through in-depth interviews with experts based on field surveys and environmental characteristics through spatial data analysis and literature research. Evaluation factors were selected based on the survey results of 31 variables for 23 K. koreana habitats. Afterwards, the importance and evaluation range for each assessment factor were selected. The selection of survey variables, assessment factors, importance of each factor and assessment range was conducted through in-depth interviews with experts at each stage. As a result, the assessment factors and importance were 16% for precipitation of the wettest month, 10% for vegetation zone, 12% for vegetation type, 10% for crown canopy vitality, 14% for tree layer coverage, 13% for drainage grade, 12% for soil depth, and 13% for distance to stream including dry stream. This study provides basic ecological information and a habitat assessment system for K. koreana habitats. Therefore, it can be used as primary data for preparing an endangered wildlife conservation policy, preparing a habitat improvement plan, and selecting an alternative habitat.

This study analyzed potential breeding sites for black-faced spoonbills on 70 non-breeding, uninhabited islands in Incheon, Korea, in order to suggest potential breeding sites for black-faced spoonbills, whose breeding population has recently been increasing. By comparing the environmental characteristics of breeding and non-breeding areas identified through a literature search, we developed a discriminant to identify potential breeding areas for black-faced spoonbills. Among a total of eight environmental variables(Island area, distance from land, distance to mudflat, distance to rice field, distance to sea route, depth of water, mudflat area, rice field area), the variables that influenced the selection of breeding sites for black-faced spoonbills were average water depth, tidal flat area, and paddy field area. As a result of discriminant analysis of breeding islands using these variables, the accuracy was found to be quite high at 80%. As a result of applying the developed discriminant to non-breeding islands located in the Incheon region, a total of 9 islands(Yongrando, Goseokdo, Beolyeom, Joreumseom, Goeriseom, Hambakdo, Moido, Bigajido, Ahyeom) were identified as potential breeding grounds for spoonbills. The research results can be used as basic data for future management of black-faced spoonbill breeding sites and selection of alternative habitats.

Climate is generally accepted as one of the major determinants of plants distribution. Plants are sensitive to bioclimates, and local variations of climate determine habitats of plants. The purpose of this paper is to identify the factors affecting the distribution of narrow-range plants in South Korea using National Survey of Natural Environment data. We developed species distribution models for 6 plant species using climate, topographic and soil factors. All 6 plants were most sensitive to climatic factors but less other factors at national scale. Meliosma myriantha, Stewartia koreana and Eurya japonica, distributed at southern and coast region in Korea, were most sensitive to precipitation and temperature. Meliosma myriantha was mostly effected by annual precipitation and precipitation of driest quarter, Stewartia koreana was effected by annual precipitation and elevation, and Eurya japonica was affected by temperature seasonality and precipitation of driest quarter. On the other hand, Spiraea salicifolia, Rhododendron micranthum and Acer tegmentosum, distributed at central and northern inland in Korea, were most sensitive to temperature and elevation. Spiraea salicifolia was affected by mean temperature of coldest quarter and annual mean temperature, Rhododendron micranthum and Acer tegmentosum were affected by mean temperature of warmest quarter and elevation. We can apply this result to future plant habitat distribution under climate change.
