Distributional surveys for vascular plants were carried out in Daecheong island, Ongjin-gun, South Korea, from 2008 to 2010. The vascular plants recognized from the island were in tatal 402 taxa that were of 90 families, 269 genus, 350 species, 3 subspecies, 43 varieties, 6 forms. Among the investigated 402 taxa, 2 Korean endemic plants, 8 rare and endangered plants which was designated by Korea Forest Service, 35 specially plants designated by the Ministry of Environment were included. The naturalized plants were identified as 40 taxa and the percentage of naturalized plants index was 9.9%. In addition, an unrecorded species, Thyrocarpus glochidiatus Maxim (Boraginaceae), was recognized from the island.

Conventional physicochemical technologies for algae growth inhibition have economical and environmental pollution problems. This study attempted to overcome the problems by nature-friendly biological inhibition technology using fibrous carrier. The experimental results showed that the most effective carrier material, polyester, exhibited the highest biofilm thickness. The removal efficiency for nutrient salts, such as nitrogen and phosphorous, and algae growth inhibition of polyester carrier was 14.59%, 6.36%, and 77%, respectively, which is higher than for control group. These result indicate that the polyester carrier is available in eutrophic lake.

The purpose of this reserch is to investigate the flora of Dumi Island. This island locates at $128^{\circ}$ 13' E. longitude and $34^{\circ}$ 41' N. latitude. As a result of our investigation, the distribution of plants on Dumi Island could be summarized as follows. The vascular plants through this investigation were 66 families, 121 genera, 127 species, 16 varieties, 2 forma, and 145 kinds. From 1945 to 1960, most Pinus densiflora and Quercus mongolica were cut and sent as fuel to the cities of Masan, Chungmu and Samchunpo. After these deforestation years, there was a change of policy in the area and then wood was substituted by coal blacks as fuel and along with this occurs reforestation. Because of the reforestation by the present administration and natural means of suctrees, Castamopsis cuspidata var. thunbergii, Camellia japonica and Machilus japonica; they were found to exist near Sheonangdang in the northern region at Hakli and at Kuchun in the south. In the central part of the island at Mt. Chunhwang there are slopes of 20-30 degrees which are cultivated by the islanders this mountain which can be cultivated and 65% or 830 islanders are farming this land. Although this 125.4 hectors is not a large portion, this mountain with its variety of growth at different elevations, seems to be very fertile causing thick growth at any level.

Several people called our attention to two books in which many new name were made by T. Nakai. Upon checking Mori and Handbook of Korea-Mandschurian Forestry, we found that there were more than 50 apparently overlooked and naked names for the Korean woody plants. Also, new combinations or avowed substitutes of some woody plants by several authors (Y. Lee, T. Lee and W. Lee) based on previously and validly published names were not validly published because their basionyms or the replaced synonyms were not clearly indicated and a full and direct reference was not given to their authors and places of valid publications, with pages or plate references and dates. These names should not be used any more. We consider it useful to summarize the results of this preliminary investigation and invalid names of woody plants are enlisted here. Hopefully, this note will alert other researchers to look into these works for other herbaceous Korean plants.

This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

In this study, arbuscular mycorrhizal fungi (AMF) were isolated and cultivated from rhizospheres of various plants in Korea. Five species belonging to four genus were identified based on spore morphology and 18S rDNA sequence analysis: Acaulospora cavernata Claroideoglomus luteum, Diversispora aurantium, D. trimurales, Rhizophagus irregularis. These fungal species have not been cultivated or reported to date in Korea, Morphological description and phylogenetic analysis for each species were presented. This result could be useful for research of AMF diversity in Korea.

The vascular plants of Is. Yeonpyeongdo regions, located in Ongjin-gun, Incheon were surveyed from May to October 2010. The vascular plants collected 4 times were consisted of total 524 taxa; 90 families, 315 genera, 459 species, 4 subspecies, 53 varieties and 8 formas respectively. Among them, 2 taxa endemic species of Korea and 8 taxa of Korean rare plants were investigated in addition to 38 taxa of specially designated plants announced by the Ministry of Environment. The naturalized plants were 66 taxa, therefore naturalized ratio was 12.6% highly.

This study was conducted to elucidate the distribution of vascular plants and their value of Mt. Samyeong. The vascular plants that were collected 10 times from October 2013 to July 2015 consisted of a total of 538 taxa; 92 families, 308genera, 466 species, 3 subspecies, 62 varieties and 7 forms. The observed rare plant species as designated by Korea Forest Service were 24 taxa. Endemic species were 25 taxa. 28 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.3% and 8.7%. Among the surveyed 538 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 220 taxa, 195 taxa, 167 taxa, 65 taxa, 25 taxa, 8 taxa, 6 taxa and 3taxa, respectively.

The seasonal changes of the flora at three samples sites such as Sockchong, Wang-gung and Chukrim hot spring by drained thermal waters were investigated from 1997 to 1998. Monthly occurrence of plant species in February and October showed more abundantly control site than that of heavy and/or light polluted sites. This trend demonstrated similarly in terms of seasonal changes of leaf area and plant growths, both fresh and dry weight, too. Cu, Zn, Ni and Pb content including plants from Sockchong hot spring site were increased from April to September at test area than that of control, while that was decreased in October. But Zn and Pb content holding plants from Wang-gung hot spring site represented higher test site than that of control. In short impacts on aquatic plants communities by thermal wastewater of sampled area have happened in the season of low temperature, and their restorations have done in summer season.
