Abstract

We studied the habitat sites of Siberian flying squirrel in Guhak-ri, Sillim-myeon, Wonju-si, Gangwon-do from March to April in 2009. We were found total 30 points of inhabitation trace types; nests 15 points(Tree nest types were 13 points, used Tree hole types hole types were 2 points) and droppings 15 points. We observed 3 individuals of Siberian flying squirrels and founded that 2 individuals of them used tree holes, and another individual used tree nest which were located in branches of Pinus densiflora. Most utilized nest trees of Siberian flying squirrel were Larix leptolepis, and also used Pinus densiflora, Betula davurica, Styrax japonica, Cornus controversa, Acer mono. Droppings trees were Prunus sargentii, Cornus controversa, Quercus xmccormickii, Acer palmatum, Acer palmatum, Betula davurica. Through the observation, we defined that flying squirrels mainly used Conifer trees as nest sites, and decideous trees as droppings.

본 연구는 2009년 3월부터 6월까지 강원도 원주시 신림면 구학리 지역에서 하늘다람쥐 둥지 및 배설물 흔적을 조사하였다. 조사지역 내의 하늘다람쥐의 흔적은 총 30개소에서 확인되었으며, 이 중 둥지가 15개소, 배설물 흔적이 15개소였다. 이 중 둥지 이용이 직접 확인된 개체는 총 3개체로 나무 구멍 둥지 1개소에서 1쌍의 하늘다람쥐를 확인할 수 있었으며, 소나무에 만들어진 나무 위 둥지에서 1개체를 확인할 수 있었다. 하늘다람쥐가 이용한 둥지의 수종은 일본잎갈나무를 주로 이용하였으며, 소나무, 물박달나무, 때죽나무, 층층나무, 고로쇠나무를 선호하는 것으로 나타났다. 배설지로 이용하는 수종은 산벚나무, 층층나무, 졸참나무, 단풍나무, 신갈나무, 물박달나무 등으로 확인되었다. 둥지는 주로 조림지 내의 침엽수 계통을 주로 이용하며, 배설지는 주로 활엽수에서 확인되었다.
