  • The study was investigated in vegetation and environmental factors of Thuja koraiensis habitats where provided for ecological evidence data for conservation and management. Study plots were located at altitudes of 1,000~1,588 m with inclinations of 10~30°. A total of 150 taxa was identified 22 quadrates in 6 study sites. The highest basal area was analyzed in Mt. Gariwangsan 49.98 ㎡/㏊ with the lowest Mt. Hwaaksan 3.46 ㎡/㏊. Thuja koraiensis forest was classified into two communities; Abeis nephrolepis-Taxus cuspidata community, Betula ermanii-Thuja koraiensis community. As a result of Multi-Response Permutation Procedures test, there was significant difference among the communities.

  • Observations and video documentation of interactions between animals living in dens, cavities, and other enclosed spaces are difficult, but they play an important role in field biology, ecology, and conservation. For example, bird parents visiting nests and feeding their nestlings may provide crucial information for testing of ecological hypotheses and may easily attract attention of participants of citizen-science ecological and conservation projects. Because of the nest concealment of cavity-nesting birds, their behaviors in the nest can only be studied by using video surveillance. Professional wildlife surveillance systems are extremely expensive. Here, we describe an inexpensive video setup that can be constructed with relatively little effort and is more affordable than any previously described system. We anticipate that the relatively low cost of about 250 USD for a battery-operated system is an important feature for citizen-science type of projects and for applications in heavily populated areas where the potential for theft and vandalism may be high. Based on our experiences, we provide methodological advice on practical aspects of using this system in the field for ecological research on birds. We highlight the low cost, easiness of construction, and potential availability to a large number of observers taking part in wildlife monitoring projects, and we offer technical help to participants of such research projects.

  • The unrecorded fungus Galactomyces pseudocandidus de Hoog & M.T. Sm. was isolated and cultured from an introduced species, Procambarus clarkii, in Korea. Two related species, Galactomyces citri-aurantii and Geotrichum candidum, have been reported, but no other Galactomyces spp. have been found in Korea. In this study, we isolated G. pseudocandidus from the digestive tract of American crayfish using RGY (river water-glucose-yeast) medium and then compared the morphological and molecular characteristics of this species with those of related species. As a result, we confirmed that G. pseudocandidus is an unrecorded fungus in Korea, so we described and reported the cultural characteristics and microstructures, such as conidia.

  • Owing to their high bioproductivity and unique physical environment, estuarine wetlands are gaining importance in national biodiversity management and habitat conservation. With regard to conservation and management of estuarine wetlands, this study analyzed the ecological characteristics of Gahwacheon Estuarine Wetland, an open estuary with various habitat types. Data from vegetation and biotic surveys have shown that 12 plant communities of five physiognomic vegetation types, including lentic herbaceous vegetation, halophytic herbaceous vegetation, and chasmophytic herbaceous vegetation. Due to the discharge of Namgang Dam and the effect of the tide, vegetation are distributed along the narrow waterside area. In terms of biodiversity, a total of 715 species, including 12 endangered wildlife species, were identified. Species diversity was relatively high in sections I and III where various riverbed structures and microhabitats were distributed. Due to the effect of the brackish water area following the inflow of seawater, endangered wildlife of various functional groups were also found to be distributed, indicating the high conservation value of that area. The collection of ecological information of the Gahwacheon Estuarine Wetland can be used as a framework for establishing the basis for conservation and management of the estuarine ecosystem and support policy establishment.

  • The Ministry of Environment of South Korea has launched its plan to establish the National Ecological Institute. An International Symposium and Workshop was held at Ewha Womans University in Seoul on Thursday, 30 September 2010, to strengthen international cooperation, networking and partnerships for the conservation of biodiversity. This symposium was attended by experts of many major institutions for biodiversity conservation from South Korea and overseas. At the symposium and workshop preceded by a keynote speech by the renowned primatologist and conservation biologist Jane Goodall the participants discussed a wide range of topics including "biodiversity conservation: in situ and ex situ approaches", "conservation of species diversity and ecosystem management", and "international cooperation for biodiversity conservation and research". As a basis for future discussions, this article summarizes how the National Ecological Institute might contribute most effectively to public life and environmental management in South Korea and worldwide. It addresses the following issues: governance and funding, synergies within Korea, participation in international networks, external advice, a broad view of ecological issues, research agenda, building on identity, public outreach, and training the next generation of scientists.

  • The purpose of this research is to verify the effect of a 3-year-old's green growth education knowledge of environmental conservation and eco-friendly attitude. This study conducted a survey of 2 classes of 3-years-old children (totaling 45 children) located in Gyeonggi Province Shiheung. The experimental group consisted of 23 children while the comparison group was comprised of 22 children. Experimental treatment period was 5 primarily by the classroom teacher in the experimental group and 12 sessions going green growth program was compared to a group, the basic curriculum was operate as usual. The results of this research are summarized as follows. First, the result of the experimental group, which participated in green growth and did not participate in the control group, show that the early childhood of the experimental group has been improved about knowledge of environmental conservation and showed a statistically significant difference. Second, the result of the experimental group which participated in green growth show that the attitude of the experimental group improved an infant's environment-friendly conscience.

  • To investigate the structure and the conservation strategy of natural forest at Nature Conservation Area in Chuwangsan, 21 plots(20$\times$20m) set up with random sampling method. Two groups were classified by cluster analysis. High positive correlations was proved between Carpinus laxiflora and Fraxinus rynchophylla, Quercus serrata and Quercus variabilis, Lindera obtusiloba and Stephanandra incisa and High negative correlations was proved between Acer mono and Fraxinus sieboldana, Acer pseudo-sieboldianum and Quercus variabilis. Species diversity(H') of investigated area was calculated 1.1306~1.2688.
