Nationally designated Cultural Properties 'Scenic site No.12 Maisan Mountain, Jinan' designated areas and some protected areas, and taking into account the dynamics of naturalized plants causing problems, we will restore the original vegetation scenery of Mt. Maisan. The results of this study are as follows. A total of 76 families, 192 genera, 286 taxa, and inland and inhabited areas, 76 and 138 genera and 163 taxa were identified in the areas of Ammaibong. The total number of naturalized plants identified in this study area is 28 taxa total, which corresponds to 7.1% naturalization rate(NR) among the vascular plants of all 395 taxa, and the urbanization index(UI) corresponds to 8.4% of the 333 taxa of Korean naturalized plants. Ecosystem disturbance plants identified in the survey area were Ambrosia artemisiifolia 1 taxa. The naturalized plants controlled and managed by separate anthropogenic vegetation management within the designation and protection area of Maisan scenic place are three species of herbaceous Rumex acetosella, A. artemisiifolia and Festuca arundinacea. It was identified as a breed. Indigofera bungeana and F. arundinacea communities around the stairway and Amorpha fruticosa, I. bungeana, A. artemisiifolia and Amaranthus patulus of the top of Am-Maibong were selected as the first priority sites for exclusion of exotic species in Maisan area and target naturalized plants species to the Ammaibong peak. In addition, R. acetosella community around the temple was suggested to be removed first to preserve endemic species. For the restoration of vegetation, we suggest that Stephanandra incisa, Spiraea blumei, Weigela subsessilis, etc. should be planted after removal of I. bungeana, and F. arundinacea, C. lanceolata, Carex callitrichos var. nana.

The purpose of this study was to understand the geographical and environmental distribution of wild animals in Baekdudaegan region using field survey and GIS data. Crucial factors were selected and analyzed to understand the distributional characteristics of wild animals (7 species in 6 families) and rare endemic plants (14 species in 11 families). These crucial factors include stand factors (forest type, DBH class, and crown density), soil factors (bed rock, soil texture, and organic matter), geographical factors (elevation, slope, aspect) and climatic factors (temperature, rain fall, humidity). Finally, 10 factors were selected by statistical analysis and categorized for analyzing geographical and environmental features. Four families such as Muridae, Sciuridae, Suidae and Talpidea in wild animal showed the similar habitat characteristics with the 10 factors.

Eight unusual individuals of a laminariaceaen species were collected from the Sea of Okhotsk in 1974 and described as a new species, Laminaria multiplicata Petrov et Suchovejeva in 1976. Since that time no new information, including pictures and numerical data, has been provided, although the species was cited in floristic lists of the Sea of Okhotsk based on the first record in 1976. We investigated a type and 3 paratypes of L. multiplicata and strongly believe that they were wrongfully identified abnormal plants of L. gurjanovae A. Zinova. Therefore, the species L. multiplicata needs to be closed.

A type specimen is the specimen originally used to name a new species; thus, it is one of the most significant materials for taxonomic study. In our study on the inventory and management of endemic species in Korea, we checked the type materials for Pseudolysimachion pusanensis (Y. Lee) Y. Lee, combination name Veronica pusanensis Y. Lee, recorded as deposited at the herbaria of the Ewha Womans University and the National Institute of Biological Resources, and failed to find any specimens. Thus, we concluded that all type specimens of V. pusanensis have since been misplaced. According to articles 9.11 and 9.13 of the International Code of Nomenclature for algae, fungi, and plants, it is necessary to select a neotype if the holotype is missing and no other original material exists. Therefore, we designate the neotype maintained in the herbarium of the National Institute of Biological Resources of the Republic of Korea.

Three components, fraxetin-8-glucoside, esculetin-6-glucoside and mannitol, were isolated from the stem bark of Fraxinus chiisanensis var. stenophylla, F. japonica var. intermedia and F. densata. The MeOH extract of the cortex of F. densata had the antiinflammatory activity on the carrageenin-induced paw edema in rat. The MeOH extracts of the cortex of all three Fraxinus spp. have the potent analgesic activity on the HOAc-induced writhing syndrome in mouse and the hepatoprotective activity on the $CCl_4-induced$ fatty liver in rat: protection of ballooning formation and inhibition of sGPT and sGOT increased by $CCl_4$.

This study was conducted to clarify the floristic composition and to investigate the landscape structure of habitats of Aconitum pseudo-leave var. erectum. A. pseudo-leave is designated an endemic plant in Korea. Floristic compositions of habitats were mainly composed of Quercus mongolica community. Other elements in this composition were Weigela subsessilis, Corylus sieboldiana and Cornus contioversa. Landscape ecological structure of habitats were defined by soils of mesic, loamy skeletal, slope of more than 60$^{\circ}$, sixty percent of woody coverage at 460-520m above the sea level and 25m away from drainage. Distribution patterns of A. pseudo-leave var. erectum plants in Taejon were presented on the 1km X 1km grid map.

This study was conducted to investigate the flora of Mt. Myongji and also to find the distribution characteristecs of rare and endangered plants in this mountain. Field surveys were carride out 21 times from 1991 to 1997. Main results obtained from this study were as follows; 1. Mt. Myougji was covered with Pinus koraiensis and Sarix leptolepis stands at the altitude lower than 600m, and deciduous forests which were consisted of Quercus mongolica, Carpinus sp., Acer sp., Cornus sp., Fracinus sp., etc. occupied at the altitude higher than 600m. Dicentra spectabilis population and Anemone population were remardable, and Adenophora grandiflora and Astilbe chinensis var. davidii with white flowers were found. 2. The vascular plants in Mt. Myoungji were recorded as 677 taxa such as 19 families, 358 genera 576 species 90 varieties 11 forma. Among them. 19 families 31 genera 32 taxa were endemic plants and 27 taxa were naturalized plants. 3. 26 taxa of rare and endangered plants protected by Forestry Administration were found in Mt. Myonfji. Among them, Asarum maculatum. Hanabusaya asiatica, Lilum cernum. Jeffersonia dubia, and Cypripedium japonica populations could be regarded as very important in a biogeraphical aspect. So it is necessary to monitor this area in a long term and to establish the conservation strategies.
