Hyangro-bong is located on the northern side of the civilian access control line and therefore has gone through natural ecological succession without human interference. Currently, it forms a distinctive natural ecosystem in which rare wild animals and plants are various. It is located in the Baekdudaegan mountain system and plays an ecologically important role as a bridge that connects the Geumgang mountain and Seorak mountain. This study investigated the flora of the eastern parts, Forest Genetic Resources Reserve Area, of Hyangro-bong. A total of 363 vascular plants that belonged to 77 families, 206 genera, 310 species, 3 subspecies, and 47 varieties were found in the study area. Rare and endangered plants identified in this study included the critically endangered Swertia wilfordii and endangered Irisuniflora var. caricina. Furthermore, 4 vulnerable species, Hanabusaya asiatica, Codonopsis pilosula, Leontopodium japonicum, and Taxus cuspidata, were found. A total of 7 families and 14 taxa including Aconitum pseudolaeve and Clematis fusca var. coreana were confirmed as endemic plants. Naturalized plants belonging to 4 families, 11 genera, and 13 species were distributed along the Hyangro-bong forest roads.

Distribution of vascular plants in Yangyang-gun were investigated 12 times from Apr. to Sept., 2008. In the result of survey, the flora of this area consist of 412 taxa totally; 89 families, 259 genera, 366 species, 5 subspecies, 37 varieties and 4 forms. There were remarkable plants such as 11 taxa of Korean endemic plants, 58 taxa of specific plants which were designated by the Ministry of Environment, 2 taxa of endangered plants of Ministry of Environment, 7 taxa of rare, endangered plants of Korea Forest Service and 28 taxa of afforestation plants and 296 taxa of useful plants. Furthermore, 36 taxa of naturalized plants (8.74%) were also observed in this area. Vegetation of investigated area was conserved well. However, vegetation has been destroyed rapidly due to construction of commercial complex for human recreation such as condominiums and stores. Therefore, it is need to efficient management of the water quality and vegetation by conservation strategies from huge visitors.

A survey was conducted on the vegetation of Judo and Gamagseum in warm temperate zone of Southern Korea. They are covered with natural vegetation, evergreen forest dominated with Castanopsis cuspiadata in Judo and Machilus thunbergii in Gamagseum. Judo is a small island, ca. 1.75 ha, located within the Wando port. Since the flora of Wando including the Judo was reported in 1924, some investigator have reported evergreen trees of Judo. But the list of plant species of Judo is still unavailable. Gamagseum, located at the 15km morth of Judo, is a small island, ca. 1.45 ha, cosisting of two islands, Dae-o-do and So-o-do in low tide, and the report of its flora and any other survery on its is almost none. The vegetatons of Judo and Gamagseum are an example of natural forest vegetation occured rarely in warm temperate zone because of human disturbance in the southern coast zone of the Korean Peninsula. However, the ecological study of those vegetation has not ever been made, and the ecological or plant geographical situations of their vegetation is not clear. To determine the vegetation type, listing of plant species in the islands, calculation of basal area of trees over DBH=4.5cm, Raunkiaer's life form, leaf size class, Pte.-Q and etc., were studied. Total plant species of Judo was 110 species and that of Gamagseum was 99 species. In Judo, Castanopsis cuspidata was 1384 individuals among 2359 individuals over DBH=4.5cm, and in Gamagseum, Machilus thunbergii was remarkably abundant and Castanopsis cuspidata could not be found.

이중벽의 퇴비화 용기를 사용하여 가정 생활쓰레기의 현장에서의 미생물상의 변동을 조사하였다. 그 결과는 다음과 같다. 1. 중온성 세균은 다소 완만한 변화를 보였다. 고온성 세균은 봄철을 제외하면 감소하는 경향을 보였고 중온균과 고온성 세균의 동시 증감도 관찰되었다. 2. 중온성 방선균은 겨울철 퇴비화 초기 증가하였고 봄철 퇴비화에서는 완만하게 감소하였으나 여름철에서는 다소 감소하였다. 고온성 방선균도 퇴비화 초기에 감소하였다. 3. 중온성 사상균은 퇴비화 중기 여름철에는 감소하였으나, 봄과 겨울철에는 완만한 증가를 보였고, 고온성 사상균은 전체적으로 감소하였다. 4. 암모늄 산화세균, 아질산 산화세균은 다른 보고에서보다 상당히 많이 관찰되었다.

The samples were collected at lowland swamps, reservoirs, mountainous wetlands, and sphagnum bogs from 2012 to 2014. The followings were newly recorded in Korea: two species, three varieties, and one form, including six taxa of the genus Cosmarium. The newly recorded Korean species were Cosmarium bioculatum var. hians, C. bireme, C. pseudobiremum, C. nitidulum var. pseudorectangulare, C. trilobulatum f. retusum, and C. trilobulatum var. depressum. The flora of the genus Cosmarium contains 303 taxa in total in Korea. The specimens were cultured and deposited on the algal culture collection of Kyonggi University (ACKU) and National Institute of Botanical Resources (NIBR).

Aerial algae were sampled from 28 sites on rocks, tree barks, and mosses along the Hongcheon-river in Gangwon-do, Korea, from December 2011 to September 2012 and then cultivated. Seven genera and eight species of the order Chlorococcales were newly recorded in Korea. These were Spongiococcum tetrasporum, Tetracystis aggregata, Myrmecia bisecta, Coenocystis inconstans, Lobosphaeropsis pyrenoidosa, Pseudococcomyxa simplex, Coelastrella oocystiformis, and C. vacuolata. As a result, the known Korean flora of the order Chlorococcales now includes 12 families with 54 genera, 263 species, 76 varieties, and 27 forma, giving a total of 366 taxa.

This study was performed to investigate the flora and plant resources of Mt. Gamak (537.8 m) from April to October 2007. The collected vascular plants were composed of all 478 taxa including cultivated species, and classified into 410 species, 3 subspecies, 61 varieties, and 4 forms of 284 genera under 94 families. Six taxa of the Korean endemic plants and 4 taxa of the rare and endangered plants were also distributed in this mount. Resource plants were categorized into edible 222, pasturing 208, medicinal 183, stainable 134, ornamental 96, timber 20, fiber 6 and industrial 4 taxa, respectively. Floristic geography of the investigated area was regarded as the boundary between middle parts in floristic pattern of the Korean Peninsula.

Centroceras gasparrinii is characterized by 1) straight spines, 2) an ovoid gland cell, 3) tetrasporangia with involucral branchlets, and 4) ovoid cortical cells on the first and second cortical initials. A similar Centroceras species with dichotomous habit, "Centroceras clavulatum", has been widely known as a common species of Korean marine flora. However, the species known as "C. clavulatum" in Korea is recognized as C. gasparrinii based on the molecular and morphological evidence. Newly generated sequences of rbcL gene reveal that all taxa of Centroceras from Korea having dichotomous branching pattern are C. gasparrinii. There is 0-0.07% sequence divergence among specimens of C. gasparrinii in Korea. "Centroceras clavulatum" is excluded from Korean flora and C. gasparrinii is included instead of "Centroceras clavulatum". C. gasparrinii also differs from C. distichum in Korea in that it has tetrasporangia with involucral branchlets and dichotomous branching pattern, while C. distichum has immersed tetrasporangia and an alternate branching pattern.

Marine benthic flora was investigated in an Arctic bay. Specimens of chlorophyte, phaeophyte, and rhodophyte were collected and examined over the period from July to August 2003 from Kongsfjorden Spitsbergen in Svalbard Islands. A total of 28 genera and 32 species (5 chlorophytes, 18 phaeophytes, and 9 rhodophytes) was identified and described. A green alga Enteromorpha linza(Linnaeus) J. Agardh, a brown alga Asperococcus compresus Griffiths ex Hooker, and three red algae Gracilaria gracilis (Stackhouse) Steentoft et al., Rhodymenia pacifica Kylin and Schizochlaenion rhodotrichum Wynne et Norris were recorded in Svalbard Islands for the first time.
