  • A newly naturalized plant, Amaranthus powellii S. Watson was found Jail-dong, Uijeongbu-si, Gyeonggi-do, Korea. This species is native to Southwestern USA and Northern Mexico, and it is also naturalized in worldwide of temperate regions. This species was distinguished from the related species, A. patulus Bertol. and A. hybridus L., by leave blades broadly elliptic, rhombic or lanceolate, petals unequal, without conspicuous green mid-veins, and utricle gradually narrowed toward the stigma. Korean name was given as 'Min-teol-bi-reum' to A. powellii S. Watson, based on the character, it was hairy less than the three related species, A. patulus Bertol., A. hybridus L. and A. retroflexus L., conspicuously.

  • This study carried out to certify of taxonomic delimitation in A. artemisiaefolia, A. trifida, A. trifida for. integrifolia, and A. psilostachya in the area of literature and experiment. A. psilostachya was not a vestige of naturalized in Korea and A. trifida and A. trifida for. integrifolia didn't have any valuable differences of morphological and molecular biological experiment. I arranged that naturalized species in Ambrosia are A. artemisiaefolia L. and A. trifida L. in Korea.

  • A naturalized species, Silene antirrhina L is newly reported in Korea. S. antirrhina L. was found along the Geumho riverside in Daegu. S. antirrhina L. is similar to S. koreana Kom. and S. armeria L. in that it has dark glutinous areas. S. antirrhina L. can be distinguished from congeneric species by the stamens and styles of its sepal and seed surface which are finely papillate. The Korean name of S. antirrhina L. "Ganeun-Kkunkkunijangguchea" was newly formulated based on the overall characteristics of this thin and small plant and on the Korean name of S. koreana Kom. photos of the habitat and a description and key of characteristics are provided.

  • This study presents an ecological management plan for wildbird habitat conservation, an nature-friendly enhancement of bio-diversity using the riverside of the Tancheon Ecosystem Conservation Area in Seoul by analyzing environmental and ecological characteristics. As a result of analyzing actual vegetation, vegetation type was classified into 34 types. Humulus japonicus association covers an area of 441,568.6㎡(31.44%), and Artemisia princeps var. orientalis association covers an area of 89,690.1㎡(6.39%). Sandy plain as valuable wildbird habitat covers an area of 89,965.9㎡(6.4%). 125 taxa including 34 families, 93 genera, 107 species, and 18 varieties were recorded and the number of naturalized plants were 41 taxa at the survey site. Total naturalized index(NI) and urbanized index(UI) were recorded as 32.8%, and 15.5%. As a result of analyzing the herb plants association structure by surveying 8 belt-transects, the humid native plants was dominant in the partially adjacent revetment edge and damp riverside. On the other hand, naturalized plants was so extensively dominant that it was necessary to establish an ecological management plan. The observed wildbirds belonged to 50 species, 6,118 individuals, and 7 restricted species by law, which were Accipiter gentilis, Falco tinnunculus, Buteo hemilasius, and Buteo buteo. Oriolus chinensis,Hirundo rustica, and Alcedo atthis. The ecological administration plan for Tancheon Ecosystem Conservation Area as follows: in ecological land-use planning, the conservation area(695,518.5㎡) has native woody and herb vegetation and sandy plain with water as an wildbird habitat. The restoration area(653,702.7㎡) has a naturalized plants distribution are with artificial revetment. The nature-friendly Riverside Area(55,414.9㎡) was an easily approached area with damaged riverside vegetation, and a safe area to wildbird habitat. In riverside restoration planning, the artificial riverside should be restored to its natural riverside vegetation, and the artificial embankment should be restored with edge shrubs for wildbird habitat or revegetated for natural riverside landscape. For naturalized plants management planning, we selected naturalized plant species to be weeded out, and suggested an application method for ecological management.

  • A newly naturalized plant, Viola palmata L., was found in Uljin-gun, Changwon-si, and Yangsan-si. It belongs to the subsect. Boreali-Americanae (W. Becker) Gil-Ad of the sect. Nosphinium W. Becker, which is known to be from North America, with subsequent introduction into Europe. In Korea, this species is considered to have been introduced by freight transportation through the port of Busan, after which its distribution area expanded. We propose the new Korean name 'Chang-won-je-bi-kkot' based on the location at which it was initially collected in Korea. We also provide descriptions of the morphological characters along with photographs, illustrations, and a distribution map of Viola palmata.

  • Recent field and herbarium studies have yielded three vascular plant taxa of the family Poaceae that have been documented in Korea. All of the three species, collected from Jeolla-do and adjacent areas, were introduced and naturalized. Three species are identified as Vulpia bromoides (L.) Gray, Agrostis capillaris L. and Eragrostis pectinacea (Michx.) Nees. We provide the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa are also provided.

  • This study is to offer the basic data for restoration and conservation of wetland ecosystem by surveying and analysing the flora distributed in the Binae marsh, Namhan River, Chungju-si. The flora in the Binae marsh were verified 204 taxa including 48 families, 152 genera, 179 species, 23 varieties and 2 forms. In flora, pteridophyta were 2 taxa including 1 family, 1 genus and 2 species, among angiospermae, dicotyledonae were 153 taxa including 37 families, 110 genera, 138 species, 13 varieties and 2 forms and monocotyledonae were 49 taxa including 10 families, 41 genera, 39 species and 10 varieties. In the result of classifying the life form of flora, megaphanerophytes (M), nanophanerophytes (N) and chamaiphytes (Ch) were each 9 taxa (4.4%), 37 taxa (18.1%) of hemicryptophytes (H), 19 taxa (9.3%) of geophytes (G), 97 taxa (47.6%) of therophytes (Th) and 24 taxa (11.8%) of hydrophytes (HH). The rare plant designated by Korea Forest Service was 1 taxa (Aristolochia contorta), and the endemic plant was 1 taxa (Salix koriyanagi) too. The specific plants by floristic region were 6 taxa. From among these, the species of degree I were 5 taxa including Salix chaenomeloides, Aristolochia contorta, Artemisia selengensis, Cirsium pendulum and Vallisneria natans, and degree III was 1 taxa including Alisma orientale. The naturalized plants were 45 taxa and the invasive alien plants were 3 taxa including Sicyos angulatus, Ambrosia artemisiifolia and Ambrosia trifida. The naturalized index (NI) was about 22.1%, 16.1% of urbanized index (UI) and 27.3% of disturbed index (DI). The extinct species by construction were 17 taxa including Persicaria sagittata, Typha orientalis, Zizania latifolia and so forth. The new-occured species were 14 taxa including Brassica juncea, Thlaspi arvense, Carduus crispus and so forth. The important species among the extinct species were Aristolochia contorta, Alisma orientale and Vallisneria natans.
