This research investigated soil, plants, insects and birds in the Mongchon Earth Fort, establishing the 11 plots, according to planting treatment, in order to present management method for ecological stability of species in the ground covering plots. The results of analysizing the investigated data summarize as follows. 1. In the ground covering plots without upper layer, the density and coverage of middle and low layer in the natural plots were higher than those in the artificial plots. 2. In the ground covering plots without upper layer, the density and coverage of low layer were higher than those in the artificial, while the density and coverage of herb layer in the natural plots were lower. 3. Whether there was upper layer or not, the total species diversity and enenness of the ground covering community in the natural plot without artificial treatment and natural treatment plot were higher than those ground covering. 4. In the ground covering plots with upper layer, the species diversity of ground covering in the plots without artificial treatment is high, while the species diversity in the plots with natural treatment caused the secondary succession is higher than that of the natural plot. 5. In the ground covering plots without upper layer, the species diversity in the plots with artificial management was higher than that of natural plots, while the evenness in the plots with artificial management was lower. 6. In the ground covering plots with upper layer the species diversity of insect in the plot of natural state was higher than that of insect in the plots with artifical treatment. 7. Synthetically, in the area with upper layer the species diversity of the ground covering community in the natural plot was high, while in the area without upper layer, the species diversity of it in the plots with artificial treatment was high. The insect turned up frequently in the plots of high species diversity of the ground covering, so the bird did in the plots of high species diversity of the ground covering and insects.

Yangjae stream was divided with Seoul and Gwacheon reach. Seoul reach was ecologically restored; however, Gwacheon reach was not. Similarity index of the bird communities between the two areas was relatively high, 79.9%. The dominant species in Seoul reach were Passer montanus, Pica pica, Paradoxornis webbianus and Anas crecca. The dominant species in Gwacheon reach were Passer montanus, Pica pica, Paradoxornis webbianus and Streptopelia orientalis. The different species was Anas crecca in Seoul and Streptopelia orientalis in Gwacheon. An eco-park was constructed along the stream of Seoul reach since 1996 but was not in Gwacheon reach; the number of species has increased in Seoul area($r^2$=0.846, p<0.01), but Gwacheon was not change($r^2$=0.023, p>0.05) since 1996. The number of individuals, however, was almost constant in both reaches(Seoul : $r^2$=0.211, p>0.05, Gwacheon : $r^2$=0.032, p>0.05). In Seoul reach, the ecological restoration of stream was helpful to increase bird diversity. The number of waterbirds such as herons, plovers, sandpipers and wagtails was higher in Gwacheon reach than in Seoul reach, but the number of ducks and songbirds was higher in Seoul reach than in Gwacheon reach. We suggest that the ecological restoration in Seoul area might have negative effects on sandpipers, plovers and wagtails inhabiting on the flood plain in stream, but positive effects on other species such as herons, ducks and songbirds. Especially, the increasing number of ducks was attributed to an artificial pond in flood plain. The difference in the number of Streptopelia orientalis between both reaches was owing to the habitat differences such as forest trees playing a role as patch in high revetment. From the present investigation, it could be concluded that the ecological restoration of the local stream must be carried out with consideration of water channels, sand banks and water front in addition to the high revetment for birds to attract diverse bird communities.
We have conducted a verification test of correlation between bird community indices and bird sound recording results in order to use the equipment which deals with the automatic sound collecting system, the song meter. The study areas include four sites which are Gombaeryoung and Zochimryoung in Jeombongsan Mountain and Jookryoung and Gochiryoung in Sobaeksan National Park. We collected the bird sound data five times using a sound recorder and field survey results in the same place of the study site. As a result of the sound recording from the field survey, the species recorded by three researchers of sound analyst include common resident species or species which have a relatively conspicuous call and song. On the contrary, the species recorded by only one researcher are a relatively rare or inconspicuous species or was familiar with the personal experiences of each researcher. The number of species recorded by only one researcher totaled fourteen species (36.8 %), and that of two researchers totaled twelve species (31.6 %), and that of three researchers totaled twelve species (31.6 %). The correlations of the number of species among three researchers was not significant in some results, but the sum or maximum count of the number of species was useful to estimate a significant correlation between the result of researchers and the indices of field surveys. As a result of correlation analysis by using sound recordings, the maximum number of species among the three researchers significantly correlated with the number of species, the species diversity index and the species abundance index in the field survey at the same site, however it did not correlate with the number of individuals and species evenness index. As a result of sound analysis collected from the stationary sound recording system; song meter, the number of frequencies in bird songs and calls correlated with the number of species in the field survey at the same site. The number of calls and songs decreased as time went by. Finally, we could test the active time range and change the activity strength by using a sound recording system. In particular, that sound recording system is able to collect data in same time and site, so it is expected so that the equipment not only replenish a shortage of researchers and survey periods in field research in a short term monitoring survey, but also be able to acquire statistical objectivity.

The purpose of this study was to propose the community planting method through analyzing the plant community structure of three green space types and the relationship of vegetation and wild bird inhabitation of urban environmental forest in Seoul, Korea. The results from this study showed that the vegetation stratification, coverage, and species diversity were closely related to the wild bird inhabitation. In addition, the environmental forest in study site was analyzed as a negative factor that may decrease the biodiversity. Therefore the ecological structure and environmental condition must be considered in order to improve the quality of environmental forest. Based on results in three green space types, the planting species, density and species size for proper community planting were proposed in this study. The ecological niche relationships among sixteen selected species were also presented. The results will be provided as an valueable output for the completed community planting of urban green space in the central region, Korea.
The research area, located in the northern coastal region of South Korea's West Sea, involves three bird habitats. Among these are two newly established habitats in Songdo International Business District, created by filling and developing tidal flats that were previously utilized as stopover sites for migratory birds. One of these areas showed decrease (Residual tidal flats, site.1) while the other showed increase (Artificial lake, site.2) in bird influx. The third habitat (Namdong reservoir, site.3) is a pre-existing stable habitat which has been maintained as a stable habitat. This study conducts an assessment of habitats based on avian population clusters and environmental surveys and proposes habitat management measures. A survey of bird populations and habitat environments was conducted for a total of 39 occasions from January to December 2022. The observed bird species totaled 14 families and 48 species with 20,760 individuals. Compared to the existing habitats, the newly established habitats showed relatively lower influx of bird species and individuals. During the habitat assessment, the newly established habitats were rated as I to II grade, while the existing habitat was rated as relatively high III grade on the grading assessment of the tidal flat. An analysis of habitat types revealed that the existing habitat, in which diverse strategies for habitat type diversity and mitigating anthropogenic interference were demonstrated, attracted a diverse range of bird species. Through this research, it was deduced that the diversity of habitat types plays a significant role in attracting various bird species. Upon evaluation of habitat types concerning the habitat characteristics of the bird species selected for habitat management, as habitat management measures, it is deemed that the creation of shielded green areas (referred to as 'buffer green') to minimize interference from the surroundings, the establishment of reed fields (site.1, 2) positively correlated with reservoirs, and the improvement of sandbanks (site.1) positively associated with tidal flats, the two relations which we drew from correlation analysis between occurrence species and habitat types, would contribute to the future restoration and maintenance of stable habitats. The results of this study can be applied not only to the study area but also to other development zones, such as coastal reclamation sites, which share similar geographical and environmental characteristics, including arrival sites for migratory birds.
DNA barcoding, an inventory of DNA sequences from a standardized genomic region, provides a bio-barcode for identifying and discovering species. Several recent studies suggest that the sequence diversity in a 648 bp region of the mitochondrial gene for cytochrome c oxidase I (COI) might serve as a DNA barcode for identifying animal species such as North American birds, insects and fishes. The present study tested the effectiveness of a COI barcode in discriminating Korean bird species. We determined the 5' terminus of the COI barcode for 92 species of Korean birds and found that species identification was unambiguous; the genetic differences between closely related species were, on average, 25 times higher than the differences within species. We identified only one misidentified species out of 239 specimens in a genetic resource bank, so confirming the accuracy of species identification in the banking system. We also identified two potential composite species, calling for further investigation using more samples. The finding of large COI sequence differences between species confirms the effectiveness of COI barcodes for identifying Korean bird species. To bring greater reliability to the identification of species, increased intra- and interspecies sampling, as well as supplementation of the mitochondrial barcodes with nuclear ones, is needed.
We investigated the effects of postfire logging on bird populations and communities through 57 point counts in unburned, burned and logged burned plots of coniferous forests in Samcheok, Korea. We found that lower species richness, abundance, and diversity in logged plots where were controlled by a typical postfire management. As results of guild analysis for nest sites and food resources, postfire logging reduced densities of ground-shrub nesters, primary and secondary cavity nesters, but was also related to reduction in densities of some foraging groups such as timber drillers and foliage searchers. These results suggest that snag-retention is essential for birds in burned forests and that postfire logging is incompatible with the maintenance of bird populations and communities. Consequently we need to develope guidelines of postfire management for snag-retention in burned forests through intensive researches focused on some target species such as Great spotted woodpeckers Dendrocopos major.
