Abstract

We investigated the differences in characteristics of rodent populations among unburned and two burned forest areas which were fire damaged in 2000 and 1980, Samcheok and Yangyang, Gangwon province, Korea. Apodemus peninsulae, Myodes regulus and Tamias sibiricus were captured in three study areas. Total density of rodents was the least at burned area which was damaged in 2000. Trappabilities of Apodemus peninsulae and Myodes regulus were higher in burned areas than in unburned area. However, trappability of Tamias sibiricus was the highest in unburned area. Changes in forest type and habitat structure due to time elapsed after forest fire might affect density and species composition of rodents. Mean body weight of rodents were the highest in burned area which was damaged in 2000 while the lowest in unburned area. Differences in body weight of rodents would be related with the coverage of understory. Detailed long-term ecological monitoring is needed to elucidate changes in characteristics of rodent populations after forest fire.

산불피해 후 경과년도에 따른 설치류 개체군 특성 차이를 파악하기 위해 강원도 삼척과 양양의 미피해지역 및 2000년도와 1980년도 산불피해지역에서 각각 조사를 실시하였다. 조사 결과 흰넓적다리붉은쥐, 대륙밭쥐 그리고 다람쥐 등 총 3종이 포획되었으며, 전체 포획밀도는 2000년도 산불피해지역에서 가장 낮게 나타났다. 또한, 흰넓적다리붉은쥐와 대륙밭쥐의 포획밀도는 산불 미피해지역보다 피해지역에서 높게 나타났고 다람쥐의 포획밀도는 산불 미피해지역에서 가장 높게 나타났다. 지역간 설치류의 체중을 비교한 결과 2000년도 산불피해지역에서 가장 높게 나타났으며, 산불미피해지역에서 가장 낮게 나타났다. 이러한 결과는 하층식생의 피도량과 관련이 있을 것으로 판단된다.
