The purpose of this study is to present the ecological data for conservation and management of three wetlands by surveying the vascular plants in Ganam reservoir, Ahnshim wetland and Jeomsae swamp. The whole taxa of vascular plants were 376 taxa including 90 families, 252 genera, 341 species, 7 subspecies, 24 varieties, 2 forms, 1 hybrid and 1 cultivar, and the planted species were 66 taxa including Ginkgo biloba and so on. The rare plants were 7 taxa including Euryale ferox(VU), Aristolochia contorta(LC), Koelreuteria paniculata(VU), Sagittaria trifolia(DD), Hydrocharis dubia(LC), Ottelia alismoides(LC) and Sparganium stoloniferum(VU). The Korean endemic plant was 1 taxon of Lespedeza maritima. In total, there were 21 taxa of floristic target species including 1 taxon of garde V, 2 taxa of grade IV, 6 taxa of grade III, 5 taxa of grade II and 7 taxa of grade I . The hydrophytes were 51 taxa including 36 taxa of emergent species, each 6 taxa of floating-leaved and submerged species and 3 taxa of free-floating species. The invasive alien plants were 79 taxa including 75 taxa of naturalized plants and 4 taxa of casual alien plant. The ecosystem disturbing species 6 taxa including Sicyos angulatus, Ambrosia artemisiifolia, Lactuca seriola, Symphyotrichum pilosum, Paspalum distichum and Humulus scandens.

The flora and vegetaion of the high moor in Mt. Daeam($128^{\circ}07^{\prime}E$, $38^{\circ}13^{\prime}N$) was investigated by the phytosociological method of Braun-Blanquet's from 13 - 14th June to 7 - 8th August, 1998. The flora of plants recorded in high moor was 191 taxa belonging to 53 families, 131 genera, 160 species, 30 varieties, 1 formas. The high moor vegetation of Sanguisorba tenuifolia var. alba community group in this survey trip was classified into 11 communities as follows : Carex dispalata community and Sphagnum palustre community at the interior of moor, Carex biwensis community and Juncus papillosus community at the regenerated area and Malinia japonica community, Spiraea salicifolia community, Geranium eriosteman var. megalanthum - Calamagrostis langsdorffii community, Juncus effusus var. decipiens community, Salix koreensis community, Caltha palustris var. membranacea community and Sparganium stoloniferum community at the margin of moor. As a result of this study, the change of plant communities on high moor was closely influenced by landization in relation to the disturbance of human since 1969.

This study was executed by China along with the Tumen river, which formed border of North Korea and China. As a result 91 family, 282 genera, 363 species, 57 variety 4 species, total 424 taxa of vascular plants were identified. The examination area was include the region that had various vegetation such as upper swampy land, seashore dune, a river, a high mountain grassy plain, deciduous tree zone, evergreen coniferous forest zone. The followings are representative plants, which found in an examination area but not in South Korea. Picea koraiensis, Larix gmelini var. principis-ruprechtii, Betula playphylla, Ulmus pumila, Populus koreana, Ledum palustre var. diversipilosum, Rhododendron parvifolium, Salix brachypoda, Phacelurus latifolius, Carex gotoi, Carex capricornis, Calla palustris, Aquilegia flabellata var. pumila, Lilium davuricum, Astragalus membranaceus, Trifolium lupinaster, Ledebourieila seselodeds, Polemonium racemosum, Scutellaria baicalensis, Linnaea borealis, Thladiantha dubia, Inula helenium, Trollius hondoensis, Hypocaeris ciliata, Aconitum kirinense, Aconitum arcuatum, Potentilla viscosa var. macrophylla. And there are 21 rare and endangered species, which Korean Forest Sevice designated, such as Aconitum koreanum, Acorus calamus var. angustatus, Polygonatum stenophyllum, Drosera rotundifolia, Iris setosa, Jeffersonia dubia, Lilium davuricum, Lilium cernum, Paeonia obovata, Penthorum chinense, Phacelurus latifolius, Rosa marretii, Sparganium stoloniferum, Thymus quinquecostatus, Trillium tschonoskii, Utricularia japonica, Tripterospermum japonicum, Vaccinium uliginosum, Vaccinium vitis-idaea, etc. Especially, plants like, Acanthopanax senticosus, Jeffersonia dubia and Lillum cernum which have high values of ornamental, and medical use are in an extinction crisis. High swampy land was formed to upper stream of Tumen river. It showed representative vegitation, like Carex sp., Scirpus radirans, Eriophorum latifolium. Wetlands plant and a dune plant were mixed in down stream area of Tumen river. On a dune, seashore plants, such as Carex kobomugi, Salsola collina, Raphanus sativus var. raphanistroides, Rosa rugosa, Scutellaria strigillosa, Linaria japonica, Phacelurus latifolius were appeared frequently.

This study was investigated on biodiversity and life forms of plants distributed in 28 wetlands on Jeju city, in order to apply wetlands to nature exploration sites for environmental education. The 131 kinds of the plants were found on 28 wetlands. The plant biodiversity was relatively high in Ban pond, Jeongmool, Mosanimool, Dolgaegi pond, Woot pond, and etc. The $5{\sim}6$ life forms of plants, relatively high in variousness to other wet lands, were distributed in Mosanimool, Dolgaegi pond, Woot pond, and Yeonhoa pond as well as Jeongmool and Yongsoo reservoir. The 71 kinds, which correspond to 54.2% of plants observed in this study, were identified as hydrophytes. The $4{\sim}5$ forms of hydrophytes were distributed on 23 wetlands, including Jeongmool, Mosanimool, Yongsoo reservoir, Ban pond, Dolgaegi pond, and etc. In conclusion, 5 wetlands such as Jeongmool, Yongsoo reservoir, Dolgaegi pond, Mosanimool and Woot pond were high in variousness of plant life forms as well as biodiversity of plants. These results suggest that 5 wetlands above could be applied as nature exploration sites. In addition, Korean rare and endangered plants such as Isoetes japonica, Nymphoides coreana, Utricularia japonica and Sparganium stoloniferum in this study need to be conserved.
