Abstract

Gotjawal areas have the unique ecosystem and we need to approach as the inhabit of animals to conserve Gotjawal. This study was conducted in Hangyeong-myeon Cheongsu-ri located in the western part of Jeju Island belonging to Hangyeong Andeok Gotjawal Zone and Jocheon-eup Seonheul-ri located in the eastern part of Jeju Island belonging to Jocheon Hamdeok Gotjawal Zone. Survey on advent of the birds was done twice a month from February 2013 to December 2014. A total of 66 species and 4,140 individuals in two Gotjawals were observed during the survey period. In Seonheul Gotjawal area, 53 species and 1,907 individuals were observed while it was 49 species and 2,233 individuals in Cheongsu Gotjawal area. The number of species between two Gotjawal areas was not significantly different, but the number of individuals between two Gotjawal areas was significantly different. Thirty-six species were found in both Gotjawal areas as common species and the index of similarity was 0.7. A total of 23 species were classified as the residents, 15 species as the winter visitors, 16 species as the passage migrants, 11 species as the summer visitors, and 2 species as the vagrant. Twelve species as legally protected birds including the natural monument and the endangered species were found and 8 species were found in Seonheul Gotjawal area while it was 10 species in Cheongsu Gotjawal area. The species that directly using a wetland or food resources related to water were 12 in the Seonheul and 6 species were observed in the Cheongsu Gotjawal area, but there is no significant difference between two Gotjawal areas. However, the number of individuals in Seonheul Gotjawal area was significantly higher than in that of in Cheongsu Gotjawal area. We need to research the wetlands and micro climatic condition existing in Gotjawal forests to find the cause of difference of two areas and this difference must be considered as an important indicator for the protection of Gotjawal forests.

독특한 생태계를 가지고 있는 곶자왈지역을 보호하기 위해 동물의 서식처로서의 접근이 필요하다. 본 연구는 2013년 2월부터 2014년 12월까지 월 2회 조류조사를 실시하였고 제주도 서부에 위치한 한경-안덕곶자왈지대에 속하는 제주특별자치도 제주시 한경면 청수리와 제주도 동부에 위치한 조천-함덕곶자왈지대에 속하는 제주시 조천읍 선흘리를 대상으로 하였다. 두 곶자왈지역에서 총 66종 4,140개체가 관찰되었고 선흘곶자왈지역에서는 53종 1,907개체가, 청수곶자왈지역에서는 49종 2,233개체가 조사되었다. 두 곶자왈지역간 종수는 통계적으로 차이가 없었으나, 개체수는 두 곶자왈지역간에 유의한 차이를 보였다. 두 지역간 공통종은 36종으로 유사도 지수는 0.7이었다. 계절적 출현형으로 살펴보면, 두 곶자왈지역에서 텃새는 23종, 겨울철새는 15종, 나그네새는 16종, 여름철새는 11종, 길잃은새 2종이었고 선흘곶자왈지역과 청수곶자왈지역은 비슷한 양상을 나타냈다. 천연기념물과 멸종위기야생생물을 포함한 법정보호종은 12종이었고 선흘곶자왈지역에서는 8종이, 청수곶자왈지역에서 10종이 관찰되었다. 관찰된 조류 중 습지를 직접 이용하거나 수분과 관련된 먹이자원을 이용하는 종은 선흘곶자왈지역은 12종, 청수곶자왈지역에서는 6종이 기록되었으며 통계적으로 유의한 차이는 나지 않았다. 개체수에서는 선흘곶자왈지역에서 89개체가, 청수곶자왈지역에서는 30개체가 관련 종들이었으며 두 곳을 비교하였을 때 통계적으로 유의한 차이를 보였다. 두 곶자왈지역간의 출현종 차이의 원인을 밝히기 위해 곶자왈 숲 내 형성된 습지 및 미세기후에 대한 연구가 필요하며 곶자왈지역 보전을 위한 방안 마련시 두 곶자왈 지역의 차이를 반영할 수 있어야 한다고 판단된다.
