This study was part of a continuous research project on the status of waterbirds on major wetlands on Cheju Island. This study was researched twice each month for two years, from March 1997 to February 1999. In total, 29 species consisting of 4,887 individual birds were observed. The number of individuals of shorebirds was greater in the spring migratory season than in the autumn - in 1997, 131 birds in the spring, 104 birds in the autumn and in 1998, 2,453 birds in the spring, 635 birds in the autumn Pheasant-tailed Jacana, Eurasian Oystercatcher, Pintail Snipe and Temminck's Stint observed at the Hado-ri or Sungsan-po fishfarm are the first recordes on Cheju Island, Korea. Rare and endangered species were observed such as Eurasian Oystercatcher, Long-billed Plover, Far Eastern Curlew, and Spoon-billed Sandpiper. This survey area used for a suitable roosting and feeding place by many shorebirds. Thus, there is a need of critical plans for the conservation and management of shorebirds migrating in this area.

본 연구는 제주도 주요 습지에 도래하는 도요ㆍ물떼새류의 지소적인 연구의 일환으로, 1998년 3월부터 2000년 2월까지 2년간 매월 2회씩, 1) 동부지역(하도리 양어장, 종달리 해안 및 성산포 양어장)과, 2)서부지역(용수리 저수지, 금등리 해안 및 대정읍 일과리 해안)으로 나누어 조사하였다. 조사기간 중 2개 지역에서 관찰된 도요ㆍ물떼새류는 총 45종 5,117개체였으며, 지역별로는 동부지역에서 40종 4,910개체, 서부지역에서 38종 927개체로 나타났다. 계절별로는 봄철 2,821개체, 가을철 1,229개체로 봄철에 도래하는 개체수가 가을철보다 많았다. 우점종은 제1차 조사기간인 봄철에는 민물도요 Calidris alpina 2,024개체(88.5%), 흰물떼새 Charadrius alexandrinus 84개체(3.7%), 흰목물떼새 Charadrius placidus 11개체(2.4%)의 순으로 나타났으며, 가을철에도 민물도요 384개체(82.9%), 흰물떼새 20개체(4.3%), 흰목물떼새 11개체(2.4%)의 순으로 나타났다. 제2차 조사기간에는 봄철에 좀도요 Calidria ruficollis 116개체(21.8%), 민물도요 67개체(12.6%), 청다리도요 Tringa nebularia 58개체(10.9%)의 순으로, 가을철에는 민물도요 191개체(24.9%), 노랑발도요 T. brevipes 156개체(20.4%), 삑삑도요 T. ochropus 104개체(13.6%)의 순으로 나타났다. 동부지역은 서부지역에 비하여 우점도는 높았으나, 종다양도와 균등도는 낮게 나타났다. 동부지역과 서부지역간의 유사도는 0.85였다. 본 연구를 통해 물꿩 Hydrophasianus chirurgus, 검은머리물떼새 Haematopus ostralegus, 바늘꼬리도요 Gallinago stenura, 흰꼬리좀도요 Calidrius temminckii 등 4종의 제주도 미기록종과, 검은머리물떼새, 흰목물떼새, 넓적부리도요 Eurynorhynchus pygmeus, 알락꼬리마도요 Numenius madagascariensis 등 3종의 환경부 지정 보호조류가 관찰되었다. This study was part of a continuous research project on the status of migrating shorebirds on major wetlands in Cheju Island. This study was conducted twice every month for two years, from March 1998 to February 2000. The investigated location are mainly two areas. The first census areas were Hado-ri fishfarm and the coast of Jongdal-ri in Kujaw-up and Sungsan-po fishfarm in Sungsan-up, all located in the eastern part of Cheju Island. The second census areas were Yongsu-ri reservoir and the coast of Kumdung-ri in Hangyoung-myon and the coast of Ilgwa-ri in Dejong-up, all located in the western part of Cheju Island. In total, 45 species consisting 5,117 individuals were observed during the census period. There were 40 species and 4,910 individuals in the eastern area, 38 species and 927 individuals in the western area. The number of individuals of shorebirds in the spring migratory season was greater than in the autumn. The dominant species researched during the first census period were 2,024 individuals of Calidrius alpina (88.5%), 84 individuals of Charadrius alexandrinus (3.7%), 59 individuals of Charadrius placidus (2.6%) in spring and 384 individuals of Calidrius alpina (82.9%), 20 individuals of Charadrius alexandrinus (4.3%), 11 individuals of Charadrius placidus (2.4%) in autumn. The dominant species researched during the second census period were 116 individuals of Calidrius ruficolis (21.8%), 67 individuals of Calidrius alpina (12.6%), 58 individuals of Tringa nebularia (10.9%) in spring and 191 individuals of Calidrius alpina (24.9%), 156 individuals of Tringa brebipes (20.4%), 104 individuals of Tringa ochropus (13.6%) in autumn. Dominance index were recorded better in the eastern area than the western area, but species diversity and evenness index were recorded lower in the eastern area than the western area. Similarity index were 0.85 between the eastern area and the western area. Hydrophasianus chirurgus, Haematopus ostralegus, Gallinago stenura and Calidrius temminuckii, which are observed during the census period are previously unrecorded species on Cheju Island. Rare and endangered species were observed such as Haematopus ostralegus, Charadrius placidus, Numenius madagascariensis, and Eurynorhynchus pygmeus.
