Abstract

Disturbance to marine wildlife is a serious negative impact of marine debris. In this study, the percentages of Black-faced Spoonbill nests that included plastic marine debris were calculated from surveys conducted on an islet named Suhaam off the western coast of South Korea. The percentages of nests including plastic decreased from 71% in 2010 to 37% in 2011 to 33% in 2012. The total number of nests increased from 28 in 2010 to 38 in 2011 to 43 in 2012. These differences in nests and nesting materials were possibly due to natural nesting materials such as tree branches and rice straws that were provided at the breeding site as a protective action in 2011 and 2012. Additional conservation efforts should be made to prevent further negative impacts from marine debris.

해양 생물에 대한 교란은 해양쓰레기의 악영향 중 하나이다. 이 연구에서는 한국의 서해안에 있는 수하암이라는 섬에서 수행된 조사를 바탕으로 플라스틱 해양쓰레기를 포함하고 있는 저어새 둥지의 비율이 계산되었다. 플라스틱을 포함하고 있는 둥지의 비율은 2010년 71%에서 2011년 37%, 2012년 33%로 줄어들었다. 전체 둥지의 개수는 2010년 28개에서 2011년 38개, 2012년 43개로 늘어났다. 이 번식지에 2011년과 2012년에 나뭇가지와 볏짚 등의 자연물 둥지 재료가 공급되었는데, 이런 보호 활동이 위와 같은 변화의 한 원인으로 보인다. 해양쓰레기의 악영향을 줄이기 위해 추가적인 보호 활동이 필요하다.
