Abstract

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.

본 연구지역은 우리나라 서해북부 초입부로 철새류의 중간기착지로 이용되던 갯벌을 매립하고 조성된 송도국제자유도시에서 조류 이입이 확인된 축소(잔존갯벌, site.1) 및 창출(인공호수, site.2)된 서식지 2개소와 개발 전 부터 안정된 서식지를 유지하고 있는 서식지 1개소(남동유수지, site.3)를 대상으로 실시한 조류군집과 서식환경조사를 기초로 서식지 평가를 실시하고 서식지 관리방안을 제안하였다. 2022년 1월부터 12월까지(총 39차례) 관찰된 조류는 총 14과 48종 20,760개체로 기존 서식지에 비해 새로 조성된 서식지로 이입되는 종과 개체수가 상대적으로 적었고 서식지 평가 중 갯벌등급에서 축소나 창출된 서식지는 I~II등급인 반면 기존 서식지는 상대적으로 높은 III등급으로 평가되었다. 서식지유형에 대한 분석에서 유형별 면적보다는 유형의 다양성과 인위적 간섭에 대한 대책이 확보된 기존 서식지에서 다양한 조류의 서식이 확인 되었는 바, 서식지유형의 다양성이 다양한 조류의 유입에 관여한다는 것을 알 수 있었다. 서식지 관리를 위한 조류종을 선정하고, 선정된 종의 서식특성을 고려한 서식지 유형별 평가를 통한 서식지 관리계획 수립방안으로 주변으로부터 간섭을 최소화할 수 있는 차폐녹지조성(=완충녹지)과 출현종 및 서식지유형간 상관분석을 통해 저수지와 양의 상관관계에 있는 갈대숲의 창출(site.1, 2)과 서식밀도가 높고 주요서식지 유형인 갯벌과 양의 상관관계가 있는 모래톱의 개선(site.1)을 통해 향후 안정된 서식지가 복원 유지될 수 있을 것으로 판단된다. 본 연구를 통해 연구대상지와 입지적이나 환경이 유사한 서해안 간척(매립)지역 등 개발예정지역의 철새류 도래지역에서 적용할 수 있을 것으로 기대된다.
