Differences in Breeding Bird Communities Caused by Different Distance from the Road

도로로부터 거리가 다른 지역에서 번식기 조류군집의 차이

  • Published : 2003.02.01

Abstract

This study was conducted to clarify the influence of national road construction on breeding bird community from April to June 2002 in 8 fragmented forest areas of Baekdudaegan mountain ranges, Korea. There were more observed birds in 50∼100m areas than in 50m areas from road. Guild structures were different between both areas. Number of species and individuals belong to hole nesting and canopy foraging guilds were lower in 50m areas than in 50∼100m areas from roads. Habitat structure of breeding bird community would be changed by road construction.

도로의 건설로 인해 산림생태계의 단절이 발생한 백두대간의 진부령, 진고개, 삽당령, 백복령, 화방재, 이화령, 덕산재, 여원재 등 8개 국도 지역에서 번식기 조류군집을 대상으로 2002년 4월부터 6월까지의 기간동안 도로로부터 거리가 다른 지역별 번식기 조류군집의 특성을 파악하였다. 도로로부터 가까운 지역보다 먼지역에서 관찰된 종수와 개체수가 많았다. 또한 길드 구조의 분석 결과 도로의 인접지역이 도로로부터 멀리 떨어져 있는 지역보다 나무구멍 둥지자원과 수관층 먹이자원을 이용하는 조류의 종수와 개체수가 적었다. 이는 도로의 건설로 인해 조류의 서식지 환경이 변화하게 되고 그 결과 조류군집 구조에 영향을 주는 것으로 판단된다.
