Abstract

There are some factors affecting the shorebirds in selecting a coastal inland roost site where they have to stay during the high tide when the entire intertidal zone is covered with water. We investigated eight species (Eastern Curlews Numenius madagascariensis, Green Shanks Tringa nebularia, Bar-tailed Godwits Limosa lapponica, Grey Plovers Pluvialis squatarola, Dunlins Calidris alpine, Whimbrels Numenius phaeopus, Eurasian Curlews Numenius arquata and Terek Sandpipers Xenus cinereus) to identify the spatial and temporal variability in coastal inland roost use in the area and the factors influencing the use. We considered the area and length of the standing water in the roost site, temperature, wind speed, the time of migration and the intensity of disturbance. As a result, number of individuals and type of species using the roost site varied across spatial and temporal scales. And the factors affecting the roost use was species-specific. The roost site of the study area was a closed shrimp farm however, it has been converted to a Salicornia herbacea, a salt marsh plant, farm recently. In a situation where coastal inland roost site is needed, we hereby describe a resolution for the juxtaposition of shorebirds and farming.

도요 물떼새들은 만조시에 해안 내륙 휴식지에서 휴식을 취하는데, 휴식지를 선택할 때 여러 가지 요소들을 고려한다. 우리는 도요 물떼새 8종(알락꼬리마도요 Numenius madagascariensis, 청다리도요 Tringa nebularia, 큰뒷부리도요 Limosa lapponica, 개꿩 Pluvialis squatarola, 민물도요 Calidris alpine, 중부리도요 Numenius phaeopus, 마도요 Numenius arquata, 뒷부리도요 Xenus cinereus)을 대상으로 휴식지의 시공간적 이용과 그 이용에 영향을 미치는 요인들을 분석하였다. 휴식지 내 고인 물의 면적과 길이, 기온, 풍속, 종별로 이동시기, 방해정도를 변수로 고려하였다. 시공간적으로, 이용하는 종이 달랐으며 개체수 또한 변동을 거듭하였다. 그리고 도요 물떼새의 휴식지 이용에 영향을 미치는 요인은 종-특이적이었다. 연구지역의 휴식지는 폐장한 새우양식장이었으나 조사 기간 중 염생습지에서 자라는 함초 Salicornia herbacea 농장으로 전환하였다. 휴식지가 필요한 상황에서, 도요 물떼새들의 생태를 기초로 해서 기존 휴식지를 관리할 것을 권한다. 더불어, 여름철 가뭄에는 양식장의 수문을 열어주어 도요 물떼새들이 물을 이용해 체온관리를 할 수 있게 해주고, 만조시 도요 물떼새들이 양식장 안으로 날아 들어올 수 있도록 새들이 휴식지를 찾기 시작하는 만조 전네 시간부터는 농장 작업을 안 할 것을 권한다.
