Abstract

This study conducted a survey from April 2021 to December 2022 to investigate habitat factors affecting bird diversity in the region between Cheonwangbong Peak and Aghwibong in Baekdudaegan protected area, South Korea. Since the region has a spatial scale of 736.4 km2 and is an area where a wide variety of habitats are mixed, we selected 20 survey areas of 3 km x 3 km by analysis of habitat homogeneity. As a result of analyzing the relationship between habitat environment and bird diversity in the survey area, it was found that the diversity of bird communities was directly or indirectly related to the diversity of terrestrial insects, slope, average habitat area, mean size of patches, elevation, and forest type, and distance from agricultural land. The slope of habitat, forest type, and distance from agricultural land affect the occurrence of food sources directly and indirectly, and the average area of habitats and forest type is closely related to the structural diversity of habitats. Therefore, it is determined that the diversity of bird communities is affected by the amount of food generated within the habitat and the diversity of habitats. It is determined that the relationship between bird communities and habitat environments in this surveyed region can be basic ecological data for establishing forest management measures to promote the diversity of bird communities.

본 연구는 백두대간보호지역의 천왕봉에서 악휘봉 구간을 대상으로 조류의 다양성에 영향을 주는 서식지 요인을 구명하기 위해 2021년 4월부터 2022년 12월까지 수행되었다. 백두대간보호지역의 천왕봉에서 악휘봉 구간은 공간적 규모가 736.4km2로 광범위하고 다양한 서식 환경이 혼재하는 지역이다. 그에 따라 조사지역은 서식지 동질성 분석을 통해 3km×3km의 조사구를 선정하여 20개의 조사구를 대상으로 수행하였다. 조사지역의 서식지 환경과 조류의 다양성 사이의 관계를 분석한 결과 조류 군집의 다양성은 육상곤충의 다양성을 비롯하여 경사도, 서식지의 평균 면적, 임상과 해발고도, 농경지와의 거리와 직·간접적으로 관련이 있는 것으로 나타났다. 서식지의 경사도를 비롯한 임상, 농경지로부터의 거리는 먹이원의 발생에 직·간접적으로 영향을 주며 서식지의 평균 면적과 임상은 서식지의 구조적 다양성과 밀접하게 관련된다. 따라서 조류 군집의 다양성은 서식지 내 먹이의 발생량과 서식지의 다양성에 영향을 받는 것으로 판단된다. 본 연구의 조류 군집과 서식지 환경의 관계는 조류 군집의 다양성 증진을 위한 산림의 관리방안을 수립하는데 기초 생태 자료가 될 수 있을 것으로 판단된다.
