A Study on the Bird Diversity of Gang-neung Watersheds Region
강릉일대 수계의 조류다양성 연구
그동안 강릉일대에 보다 체계적인 조류에 관한 조사나 연구가 없었는데 이번에 한국교원대학교 박정미님 께서 강릉일대의 조류상에 관한 논문을 쓰셨습니다. 이것을 계기로 다른지역에 비해 조류 연구가 취약한 강릉을 비롯한 영동지역에 연구가 보다 활발하기를 바랍니다. 다음은 논문 요약과 결론 및 제언 일부를 넣었습니다.
Naturally formed lagoons around Gang-neung
watersheds region, in the east coast of Korea, provide a characteristic habitats
for resident and migratory birds. The bird fauna of this region, however, have
not been paid much attention and not regularly studied. This study aimed to
evaluate the birds diversity in the Gang-neung vicinity watersheds boundaries
and to determine importance of the area as a habitats for birds.
cha) were dominant species in the areas. For species richness by monthly account, the highest individuals, 8,232, was observed in December, whereas, the lowest, 1,143, in July. For the species diversity by each month comparison, the most species, 60, were observed in April, and least species, 30, were observed in July. During the birds' spring and autumn migration seasons, the species diversity was higher, especially for shorebirds, waterfowls and gulls in proportion. Dominance record compared for each study sites showed that gulls were mostly dominant at Yeongok river estuary than shorebirds and waterfowls, and waterfowls and gulls were dominant at Kyoungpo lake, an exception of the June 2002 when a flock of Far Eastern Curlews(Mumenius madagascariensis) were temporarily staged on the way of migration. Likewise, waterfowls and gulls were dominant group at Namdae estuary site. Of all birds observed in the areas, nine species were legally protected as Natural Monument, four species were
protected as endangered species and 10 species as protection species designated by the Ministry of Environment. Eight species were Red Data species of international importance. As for gulls, a major dominant group, 30,325 individuals of 15 species were observed, marking the highest percentage(63.99%) of all the regional bird community. Another dominant group was waterfowls, 13,446 individuals of 22 species were observed, which is 28.24 percent of all. In comparison to the previous survey data, a higher diversity of birds are regularly utilizing this region's habitats. A total 127 species, which is a large portion(29%) of Korea's bird diversity, were observed in the study area. Therefore, it suggests that the Gang-neung area's watersheds boundaries are vital habitats for migratory birds as well as resident and wintering bird communities.
