The investigation was made about distribution and ecological characteristics of host plant for Phellinus linteus at habitats in Gangwon-Do. The habitats of P. linteus are the place where the fog is much generated and there is lots of the moisture. The flora of the vascular plants in P. linteus habitats were consisted of 76 taxa; 62 species, 10 varieties and 4 formas of 62 genera of 40 families. The plants of infiltration type were found 70% around P. linteus habitats. This results shows that the natural environments of P. linteus habitat is very stable condition. The categories of vegetation were classified into two types. The host plant for P. linteus appeared 61.6% from Populus tomentiglandulosa. The first type showed up above the sea about 600m and west exposure region. The second type was investigated around the facing north region of the steep slope-land.

The purpose of this study was conducted in order to provide the necessary basic data, to establish management solutions and to improve biodiversity by calculating similarity index, urbanization index (UI), and disturbed index (DI) to understand current status of naturalized and invasive alien plants in Eulsukdo, Maekdo and Samnak ecological parks in Busan, South Korea. The numbers of naturalized plants identified in these parks were 76 taxa; 20 families, 53 genera, and 76 species. As a result of the similarity index analysis, the most similarity level (83.0%) was obtained at Eulsukdo and Maekdo parks. The numbers of invasive plants identified in the two parks were 11 taxa; Rumex acetosella L., Sicyos angulatus L., Solanum carolinense L., Ambrosia artemisiifolia L., Ambrosia trifida L., Hypochaeris radicata L., Lactuca serriola L., Solidago altissima L., Symphyotrichum pilosum (Willd.) G.L.Nesom, Paspalum distichum L., and Humulus scandens (Lour.) Merr. Overall, UI and DI were 28.6% and 66.7%, respectively, indicating that the ecosystem disruption was serious.

A palustrine wetland is a type of a wetland that prevails in Korea as well as an ecosystem that provides various ecological functions and has affluent biodiversity. This study was conducted to understand the characteristics of vegetation in a palustrine wetland by analyzing a life form and naturalized plants, in order to present the maintenance and utilization plan of a small wetland. A total of 249 taxa including 76 families, 188 generics, 209 species, 38 varieties and 2 forma were found at six investigated wetlands. As a result of the appearance ratio analysis, Therophytes (37.8%) with 94 taxa and Hemicryptophytes (31.3%) with 78 taxa were in order of life form, and Gramineae (14.1 %) with 35 taxa and Compositae (11.2 %) with 28 taxa were in order of family level. These were deemed representative vegetation in a palustrine wetland. Equosetum arvense, Phragmites communis, Commelina communis, Persicaria thunbergii, Arenaria serpyllifolia, Stellaria media, Erigeron annuus, Erigeron canadensis and Artemisia princeps var, orientalis were found continuously for a period of investigation in all sites. Equosetum arvense, Phragmites communis and Persicaria thunbergii were species with high appearance frequency. Especially, Persicaria thunbergii was construed high in a cover ratio in May as it develop first among Hydrophytes and form a canopy sooner than anything else. We found that a degree of naturalization and an urbanization index appear comparatively high in Yeongok-ri, Cheonan, Gangjang-ri, Asan and Yodang-ri, Hwasung, which is construed due to artificial interference, such as fanning, fishing, swimming and green-tour program. These results would be used to utilize in restoring a deserted and damaged wetland and to provide fundamental data in creating a wetland as follows.

This study was conducted from March to October 2003 to investigate the distribution status and environmental index of naturalized plants at 14 sites at rivers penetrating the downtown area of Gwangju Metropolitan City. The flora consisted of 309 taxa, 76 families, 211 genera, 273 species, 35 varieties and one form, while the naturalized plants consisted of 46 taxa, 14 families, 36 genera, 44 species and two varieties. The dominant species of Gwangju-cheon were nine taxa. Panicum dichotomiflorum, Rumex crispus, Chenopodium album, Trifolium repens, Veronica persica, Ambrosia artemisiifolia var. elatior, Aster pilosus, Bidens frondosa and Taraxacum offici-nale. The dominant species of Hwangryong River were five taxa: Rumex crispus, Trifolium repens, Oenothera odorata, Ambrosia artemisiifolia var. elatior and Erigeron canadensis. At Yeongsan River appeared 16 dominant species: Patspalum distichum, Ckenopodium ficifolium, Lepidium apetalum, Erigeron annuus and Xanthium strumarium in addition to the same dominant species of Gwangju-cheon and Hwangryong River The Urbanization Index (UI) was 17.2% and the Naturalized Index (NI) was 14.9% at urban rivers of Gwangju. The naturalized plants consisted of 16 taxa, which originated in both Europe and North America. Based upon the UI and NI, the urban rivers and their riversides must be considered a major corridor for the invasion of naturalized plants.

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 great part of the traditional knowledge on ethnobotanical plants and their uses is gradually vanishing due to industrialization, therefore ethnobotanical studies that explore and preserve the knowledge are in urgent needed before the knowledge are lost ever. This study was conducted to record and conserve the traditional knowledge of botanical taxa in Korea from 2006 to 2014. According to the survey results, derived from 17,328 sheets of 1,771 residents at 868 places, the ethnobotanical plants in Korea consisted of a total 924 taxa; 130 families, 493 genera, 813 species, 7 subspecies, 92 varieties and 12 form. Of them, herbs were 619 taxa (67.0%) and woody plants were 305 taxa (33.0%). 707 taxa (76.5%) out of 924 taxa grow wild, 44 taxa (4.8%) were cultivated wild species, 145 taxa (15.7%) were introduced for cultivation, and 28 taxa (3.0%) were naturalized plants. The analysis of usage for 924 taxa showed that the edible use was the highest with 58.9%, followed by medicinal with 26.9%, material with 3.7% and ornamental with 2.3%, respectively. The leaf of plant was the most useful part, followed by stem and root. Quantitative analysis of the ethnobotanical plants in Korea was performed by the basic values of FC, NU and UR, and indices of CI, RFC, RI and CV. As a result, The CI place Artemisia princeps in first position, followed by Aster scaber, Kalopanax septemlobus. The RFC place A. scaber in first position, followed by A. princeps, Aralia elata. The RI place A. princeps in first position, followed by Pinus densiflora, Morus alba. The CV place A. princeps in first position, followed by P. densiflora, K. septemlobus.
