This study aims to establish the national strategy for biodiversity conservation by analyzing the current status of ecodiversity as the foundation of biodiversity conservation. Furthermore, this study has another purpose of preparing the measures for conservation and restoration of biodiversity. Ecodiversity was discussed as the basis for conserving biodiversity. Five climate zones and 14 climatic regions, eight plant geographic regions, three massifs and major geologic series, horizontal and vertical topographic conditions, 16 ecoregions, major ecosystems including forest, river and streams, wetlands, coast and marine, agriculture, and urban esosystems, and land use types were discussed as the element of the ecodiversity. In terms of biodiversity conservation, the actual conditions of each ecological unit were reviewed and measures were proposed to reduce biodiversity loss. Destruction and fragmentation of habitat, poor ecosystem management due to socioeconomic changes, the effects of exotic species and chemicals, and climate change were discussed as the major factors causing biodiversity loss. Systematic monitoring based on scientific principles and ecological restoration based on those monitoring results were recommended as measures for biodiversity conservation.

Evaluation of the effects of the river restoration in Hwangji Stream, the upstream reach of the Nakdong River

임봉순,설재원,이창석 한국생태학회 2024 Journal of Ecology and Environment Vol.48 No.1

Background: In Korea, riparian zones and some floodplains have been converted into agricultural fields and urban areas. However, there are essential for maintaining biodiversity, as they are important ecological spaces. There are also very important spaces for humanity, as they perform various ecosystem services in a changing environment including climate change. Due to the importance of rivers, river restoration projects have been promoted for a long time, but their achievement has been insignificant. Development should be pursued by thoroughly evaluating the success of the restoration project. Ecological restoration is to accelerate succession, a process that a disturbed ecosystem recovers itself, with human assistance. Ecological restoration can be a test bed for testing ecological theories in the field. In this respect, ecological restoration should go beyond a ‘simple landscaping exercise’ and apply ecological models and theories in restoration practice. Results: The cross-section of the restored stream is far from natural rivers due to its steep slope and artificial material. The vegetation profiles of the restored streams did not reflect the flooding regime of the river. The species composition of the vegetation in the restored stream showed a significant difference from that of the reference stream, and was also different from that of an unrestored urban stream. Although species richness was high and the proportion of exotic species was low in the restored stream, the effect was offset by the high proportion of gardening and landscaping plants or obligate terrestrial plants. Conclusions: Based on both the morphological and ecological characteristics of the river, the restoration effect in the restored stream was evaluated to be very low. In order to solve the problems, a systematic adaptive management plan is urgently required. Furthermore, it is necessary to institutionalize the evaluation of restoration effects for the development of river restoration projects in the future.

This study aimed to isolate and characterize wild yeast strains from the vineyard soil inKorea. Twenty yeast strains were isolated from vineyard soil in Gimpo-si, Gyeonggi-do, Korea,where Vitis labrusca cv. Campbell Early is grown. Eighteen strains were previously recordedin Korea. The remaining two, Cyberlindnera mrakii VG-21-10C and Starmerella bacillaris GR9were not previously recorded in Korea. The mycological characteristics of VG-21-10C and GR9were investigated. Both were oval-shaped, convex, and smooth. However, differences wereevident in colony color and carbon assimilation activities. Strain VG-21-10C is white-coloredand assimilates glucose, glycerol, D-xylose, D-cellobiose, D-saccharose, and D-raffinose ascarbon sources. Strain GR9 is cream-colored and assimilates glucose, D-saccharose, andD-raffinose as carbon sources.

This study was carried out to evaluate the restoration effect in the restored Yangjae stream and to draw up an adaptive management plan based on the results. As the result of evaluation on the restoration effect, the restored Yangjae stream was evaluated with low naturalness in both terms of the morphology of the stream and the composition and spatial distribution of vegetation. The diverse functional groups were introduced in the vegetation restoration, but the flooding regime, which is significant in the spatial distribution of riparian vegetation, were not correctly reflected. Exotic species or species that were not ecologically suitable for the location were introduced on the embankment and thus a measure to improve those problems is required. As the ecological principle was not reflected in the restoration plan, the stream was constructed as the double terrace structure. Therefore, the width of the waterway was narrowed further, and the waterfront was not designed to accommodate changes from flooding disturbance, making the micro-topography of the stream simpler and the naturalness lower. The adaptive management plan was prepared to improve those problems, and a plan for creating an ecological network was recommended to enhance the restoration effect.

Biotope, which represents the characteristic habitats of living organisms, need to be identified as essential for the efficient creation and sustainable management of urban ecosystems. This study was carried out to provide the basic information for ecological urban planning by analyzing types and attributes of the biotop established throughout the whole area of the Pohang city, a representative industrial city in Korea. The biotop established in Pohang city is composed of 12 types including forests (coniferous, deciduous, and mixed forests), agricultural fields (rice paddy and upland field), green facilities, river, reservoir, bare ground, residential area, public facilities, commercial area, industrial area, roads, and schools. As a result of analyzing the properties according to biotop types, industrial, commercial and residential areas, which represent urban areas, was dominated by introduced vegetation. Moreover the introduced vegetation is usually composed of exotic plants or modified forms for landscape architecture and horticulture rather than native plants, which reflects ecological property of both region and site. As the distance from the urban center increases, the agricultural field showed a form of typical farmland, whereas the closer it is, the more form of greenhouse farming. Natural green spaces were divided into riparian vegetation established along the stream and forest vegetation. Forest vegetation is consisted of secondary forests (seven communities) and plantations (three communities). The urban landscape of Pohang city is dominated by the industrial area. Among them, the steel industry, which occurs large amounts of heat pollution and carbon dioxide, occupies a large proportion. On the other hand, green space is very insufficient in quantity and inferior in quality. This study proposed several restoration plans and further, a green network, which ties the existing green spaces and the green space to be restored as a strategy to improve the environmental quality in this area.

Wetlands of Dongbaekdongsan were classified into two types of pond and vernal pool. 11 plant communities are established there such as Nymphoides indica community, Sparganium stoloniferum Community, Persicaria hastato-auriculata community, Scirpus triangulatus community, Triadenum japonica community, Juncus papillosus community, Deinostema violacea community, Centipeda minima community, Apocynum sibiricum community, Isachne globosa community, and Ulmus parvifolia community. Nymphoides indica community is established in a pond located on the entrance of the Dongbaekdongsan and Persicaria hastatoauriculata community appears on edge of the pond. Sparganium stoloniferum community is formed in nearby pond with relatively shallow water and Persicaria hastatoauriculata community is established on margin of the pond. Vernal pools had been used for drinking water source and for livestock in some cases in the past. Scirpus triangulatus community is established in the most wet site as the center of the pools and Juncus papillosus community - Deinostema violacea community - Triadenum japonica community, and Apocynum sibiricum community appear in a concentric circle pattern as far away there. Ulmus parvifolia community is established in a dry vernal pool. This is the first study on vernal pool carried out in Korea. Therefore, most vegetation types are new ones different from existing studies on wetland. 동백동산 습지는 못과 한시적 못으로 구분되었다. 어리연꽃군락, 흑삼릉군락, 좁은잎미꾸리낚시군락, 송이고랭이군락, 물고추나물군락, 청비녀골풀군락, 진땅고추풀군락, 중대가리풀군락, 수궁초군락, 기장대풀군락 및 참느릅나무군락의 11개 식물군락이 성립해 있다. 어리연꽃 군락은 동백동산입구에 위치한 한 못에 성립해 있고 좁은잎미꾸리낚시군락은 그 못의 가장자리에 성립해 있다. 흑삼릉군락은 수심이 비교적 낮은 인근의 못에 성립해 있고 그 못의 가장자리에도 좁은잎미꾸리낚시군락이 성립해 있다. 한시적 못은 과거 식수원으로 사용되었고 일부에서는 가축의 물먹이공간으로도 사용되었다. 송이고랭이군락은 그 못의 중심으로서 가장 습한 곳에 성립하고 청비녀골풀군락-진땅고추풀군락-물고추나물군락 및 수궁초군락이 그곳으로부터 멀어짐에 따라 동심원 구조로 성립해 있다. 참느릅나무군락은 상대적으로 더 건조한 한시적 못에 성립해 있다. 본 연구는 한국에서 한시적 못에 대해 처음으로 이루어진 연구이다. 따라서 본 연구에서 밝혀진 대부분의 식생유형은 습지에 대한 기존의 연구와 다른 새로운 유형으로서 그 가치가 있다.

To realize river restoration that ecological characteristics of the river are reflected, we classified the river into four reaches of valley stream, upstream, midstream, and downstream based on substrate as well as riverbed gradient obtained from the relationship between distance from the river mouth, and above sea level. Considering that the rivers of Korea have been dominated by various and intense artificial interferences over a lengthy period, we determined cross sectional range of the river based on the geological map and clarified transformation degree by reach. Vegetation profile diagram was prepared by depicting horizontal range and vertical stratification of major vegetation appearing in a belt transect of 10 m breadth installed between weirs constructed in both sides of the river. Restoration models by river reach were prepared based on breadth of waterway, bare ground, herb, shrub, and tree dominated vegetation zones on vegetation profiles wherein a flooding regime was reflected. Species composition information collected from vegetation established in each zone was systematized to use for restoring each reach ecologically. Further, background that longitudinal reaches and horizontal zones were divided, was discussed by comparing with case studies in foreign countries. In addition, necessity of ecological restoration of the river was discussed based on degree of integrity of Korean rivers, ecological significance of riparian vegetation, and importance of reference information for ecological restoration of the river.
